Then the indicator on the key willchange to Green light, press “ ENTER ” key to store, the indicator of “ ENTER ”will keep light on;d.Turn the “SET” setting switch to “OFF”, the “ENTER” indicator will turn off, thatmeans the output channel selecting procedure is completed;e.If cross interpretation is needed OPEN mode should be selected.f.Repeat the same procedure (Steps b~d) to assign all the Interpreter Consoles.(3)To Cancel Selected Output Channel (only for LOCK mode)a.Turn the “SET” from “OFF” to “ON”.b.Push the “ENTER” for 3 seconds. Then all Channel Output Indicators will turn off.c.Turn the “SET” from “ON” to “OFF”. The Console will be of factory setting now.(4)The Operation of IT-12D Interpreter Console:The Interpreter Console is designed with digital technologies and used in conjunction with interpreter headset. Each Console allows two interpreters to work on it. The operation procedures are as follows:a.At LOCK mode, when the output channel is selected an interpreter only needpush the MIC ON/OFF key to activate the microphone or deactivate it.b.At OPEN mode, an interpreter can press any Output Channel key to deliver thecorrespondent language. The available channel will show a green indicator. A flash-ing red indicator means the channel is occupied.c.Put on the headset, adjust the microphone to an appropriate position and controlthe volume (Floor language is “ORIGINAL” as defaulted). Press “MIC. A/B ON/ OFF” to start the interpretation.d.In case the interpreter doesn’t understand the floor language. He/she can select alanguage familiar with from other interpreter for relay interpretation. First press“RELAY” key, the indicator will be on, and then switch the MONITOR to choose a familiar language for interpretation.e.In case the Interpreter wants to cough, keep pressing “COUGH CUT” key to cutoff the language output, release it to continue the interpretation.f.When the speaker speaks too fast for the interpreter to follow, the interpreter canpress “SLOW” key to remind the speaker to slow down. A pulse signal will comeout as remind from the IT-12M to the speaker desk.g.Each Interpreter Console accommodates A/B two interpreters to work, the opera-tion A/B interpreter is the same.5.

The codec is used to digitise incoming audio from the microphone into PCM data and convert the PCM digital audio output of the Bluetooth chip into an analogue signal for the headphones. The codec board has a microphone input and headphone output which are compatible with standard PC headsets.The W681630 codec has several features such as power down mode and high pass filter disable (to allow frequencies down to DC to be used). The ACC-005 codec evaluation board provides options to allow these features to be tested.The W681360 incorporates a feature that allows the volume of the codec output to be digitally controlled via 3 bits of the PCM data stream. The BISM II provides an AT command (ATS589) that allows you to control the volume of the codec.This document provides you with information to prototype and evaluate your own audio application. Once you have tried out your application, you will be able to design your own audio solution based around the Winbond codec and the EZURiO Bluetooth Intelligent Serial module.Bluetooth is a trademark owned by Bluetooth SIG, Inc., USA and licensed to EZURIO Ltd.2.OverviewThe codec board is powered by an on-board 3.3V regulator to reduce noise to a minimum. The PCM control signals for the codec go directly to the Bluetooth module on the motherboard via the 10-way connector, as do the 3 push button switches. This allows the switches to be used with an external program that implements the upper portion of headset or Handsfree profile.The microphone input, designed to interface to PC compatible headsets, has a fixed gain of 16 set by external components to the codec (the amplifier itself is part of the codec). Part of the microphone signal is mixed into the headphone output signal via VR2. This feature is known as “sidetone” and allows the user to hear their own voice when speaking. It is commonly used in telephony applications to give the user the necessary audio feedback that their ears expect.The audio output gain is by default fixed at 1. By fitting VR1, the audio gain can be made adjustable.The 120mW stereo output amplifier U3 ensures that the codec board can drive standard 32Ωstereo headphones while keeping total harmonic distortion down to 0.1%.Component PlacementNote that not allcomponents are fitted –non-fitted components areshown without pads. Referto Section 7 for details ofcomponent fitment andspecification.3.Codec Board Quick Start Guide3.1 Getting StartedThe codec board is supplied with a right angle, 10 way connector that can be used to connect it to the main developers kit. If required, this should be soldered to the main board. Alternatively other connectors or ribbon cables can be used.3.2 Equipment Required (not supplied)•Headsets (with microphone) (Standard PC headsets are fine)•EZURiO Wireless Developers Kit•BISM II Bluetooth module (Firmware release V9_20_22 onwards supports audio volume control)Normally two sets of development kit are required to test both ends of an audio link. If an application is being developed with an existing endpoint, such as a mobile phone or headset, only one set may be needed.3.3 Motherboard Jumper SettingsBefore using the codec board, there is a jumper setting on the motherboard that needs to be checked. This is CB1, next to the USB adaptor, which must be removed. If fitted it will short out the PCM output from the codec and prevent it operating. CB1 is only relevant for the WLAN 802.11 data module.3.4 Procedure:1)Plug the BISM II into the socket on the Dev Kit, connect to a PC serial port and power up.See the dev kit manual for different power supply options.2)Check that AT commands are working using EZURiO terminal. (Refer to blu2i Quick StartGuide if needed)3)Run the “ATI3” command to find out the firmware release number. If it is less thanV9_20_22, contact EZURiO to get a firmware upgrade for the BISM II. (Note: older versions of firmware will work, but audio output will be at half the full volume and the ats589=7 command will not be recognised)4)Power down, plug the codec board into the dev kit and power up. Check that ATcommands are working.Configure the Slave unit as follows:AT&F* Restore system defaultsATZ Reset the unit= 4 Makeconnectable and discoverableATS512ATS0=1 Answer after 1 ringATS531=1 Keep AT command mode going after a connection isestablishedATS589=7 Set Max. Volume level (requires firmware V9_20_22)AT&W Save the above settingsATZ Reset the unit.5) Find out the Bluetooth address of the Slave Unit by typing ATI4<return>6) Configure the Master Unit as follows:AT&F* Restore System DefaultsATZ Reset the unitATS531= 1 Keep the AT commands going after a connection isestablishedATS589=7 Set volume to maximumAT&W Save to flashATZ Reset the unit.ATD008098nnnnnn Connect to the slave (substitute your slave’s Bluetoothaddress that you found in step 5 for nnnnnn)AT+BTA1 Establish an audio link – displays AUDIO ON on both sides.(Alternatively AT+BTA7 can be used and the units willnegotiate the best link type.)An Audio link is now established between the two units.AT=BTA0 will turn off the audio link (but still leave the units connected).To change volume use ATS589. ATS589=0 gives minimum, ATS589=7 gives maximum. 4.Bluetooth SCO Links – A Primer4.1 Normal SCOBluetooth uses a Synchronous Connection-Orientated link (SCO) for audio. All this means is that for an audio link, the bandwidth needed to maintain the data rates required by the audio link is pre-allocated between the master and slave. This ensures audio data is always transmitted at the required data rate, and takes priority over the transmission of digital data.The Bluetooth specification for SCO is such that there is no re-transmission if data is corrupted or lost. This explains the crackling and popping that occurs when you get to the limits of radio range.The actual data rate over the air is 64 kbits/sec. There are 1600 timeslots available per second and when a master transmits a SCO packet in one timeslot, the slave replies with its SCO packet in the next. The SCO packet size is fixed at 240 bits (30 bytes). This means when a SCO link is established using the HV3 packet type, two out of every 6 timeslots are used up by the SCO link. This means there is enough bandwidth to have up to three SCO links active between a master and slave at the same time. In this scenario, there are no spare timeslots for other data.There are 3 main types of SCO packets, HV1, HV2 and HV3 (High Quality Voice). As mentioned earlier, the HV3 packet type has a 1 to 1 mapping between incoming audio data and the data transmitted over the air. There is no error correction possible with HV3.With HV1, each bit is transmitted 3 times and a simple voting algorithm is used at the other end to correct for any bit errors. This means that only 10 bytes of actual audio data can be transmitted in a SCO packet. To maintain the 64 kbits/sec data rate, all 6 timeslots have to be used for the SCO link, leaving no bandwidth available for data.With HV2, an FEC algorithm is used to correct for 1 bit errors. This increases the data packet size by 50%. This means that only 20 bytes of actual audio data can be transmitted in a SCO packet. To maintain the 64 kbits/sec data rate, 4 out of every 6 timeslots are used for the SCO link.AT+BTA1 enables HV3AT+BTA2 enables HV2AT+BTA4 enables HV1AT+BTA7 allows the link manager to negotiate which packet type to use, the default is HV14.2 Enhanced SCOEnhanced SCO or eSCO was implemented as part of the 1.2 Bluetooth Core Specification Release. The main driving factor was to improve audio quality. This has been achieved by: 1)including a CRC as part of the audio data packet to allow error detection and a re-transmission request. 2)allowing higher data rates by using packets that span more than 1 timeslot 3) allowing asymmetric links to allow high quality audio to be streamed in one direction.eSCO offers significantly better audio quality, but has to be configured at both ends of the link before a unit is enabled to accept incoming connections or enquiries.To try out eSCO, add the ATS584=1 command to the commands listed in the quick start section immediately after the AT&F* and ATZ commands.Both ends of the link must be configured for eSCO for the audio link to be established. If one end is set to eSCO and the other to SCO, you will get an “AUDIO FAIL” when the AT+BTA1 command is issued.The following are the packet types associated with the AT+BTA commands for eSCO.AT+BTA1 – EV3 packet. Up to 30 bytes + CRC. Uses up 1 timeslotAT+BTA2 – EV4 packet. Up to 120 bytes + CRC + 2/3 FEC. Up to 3 timeslotsAT+BTA4 – EV5 packet. Up to 180 bytes + CRC. Up to 3 timeslots. Currently Unsupported4.3 SCO / eSCO Transport DelaysThe following delays have been measured between incoming audio and audio output at the other end of a Bluetooth link.Normal SCO: AT+BTA1 7.84 ms AT+BTA2 9.24 ms AT+BTA4 10.8 msEnhanced SCO AT+BTA1 12.1 ms AT+BTA2 33.4 ms AT+BTA4 41.2 msAs can be seen, the additional error correction of eSCO comes with a transport delay penalty. This is because a buffer is needed to ensure that there is still data to output while waiting for a corrupted data packet to be re-transmitted.For AT+BTA1 and normal SCO, the data is transmitted once every 6 timeslots so the transport delay is expected to be 6/1600 = 3.75ms. When doing loop-round testing with the codec, i.e. with no transport delay, it was found that from input to output, the codec added ~1ms of delay at 1kHz and 1.5ms at lower frequencies.4.4 PCM TimingThe codec samples at 8 kHz. The default mode of operation of the codec is 16 bit Receive Gain Adjust Mode. In this mode, in every 8 kHz cycle, 16 bits of data is clocked into the codec. The first 13 bits are PCM audio data, the last 3 bits are volume data. Of the last three bits, 000 equates to maximum volume (ATS589=7), 111 equates to minimum volume (Ats589=0).At maximum volume, the output signal matches the amplitude of the input signal at the other end of the Bluetooth link. It is more appropriate to think of this feature as being an attenuation control.The clock rate used for sampling is 250kHz (4µs). 16 clock cycles takes 64µs. 8kHz equates to 125µs.The same timing is used for all packet types in both SCO and eSCO modes.5.Frequency Response5.1 Codec Frequency ResponseThe codec frequency response can be measured by connecting PCM_IN from the codec to PCM_OUT to the codec (PCM_OUT from J1, the 10 way connector has to be disconnected). A 1kΩ pull down resistor is needed on PCM_OUT to ensure maximum volume setting.The following graph shows the measured frequency response. For this test, R32, the side-tone resistor was removed to prevent audio feedback.A 1V peak to peak sine wave was injected into the microphone circuit and its amplitude measured at TP5, A0, the input to the codec. The output from the codec was measured on TP6, PA0+.The chart below shows the codec frequency response with the High Pass Filter Enable (HB – Pin 16) pin set high and set low.As can be seen from the chart, the codec frequency response is flat between 300 and 3,300 Hz. With the high pass filter on, the 3dB points are at 150Hz and 3,600 Hz respectively. With the high pass filter off, the 3dB point goes down to approximately 15Hz.5.2 Bluetooth Link Frequency ResponseThe Codec 13bit linear data is coded within the Bluetooth chip using CVSD (Continuous Variable Slope Decode) encoding for transport over the Bluetooth link. CVSD is essentially a form of Adaptive Differential PCM (ADPCM) and is well suited for voice transmission. It is forgiving of individual bit corruption as each bit only implements an up or a down shift relative to the previous level (corruption of the MSB of a 13 bit sample would create a much larger error term than is possible with ADPCM). A draw back of ADPCM is that it cannot track large delta changes in signal quickly enough. For voice, this does not present a problem.The chart below shows the frequency response of the Bluetooth link at different levels of input sine wave.As can be seen, the frequency response can only be considered to be flat when the input voltage level is less than a 0.3V peak to peak sine wave.6.Circuit DescriptionThis section describes the individual parts of the circuit and give design information aboutthe components, to allow you to adapt the circuitry of the codec board for your own implementation.6.1 Audio AmplifierThe Winbond codec is capable of driving a 32Ω load directly if the gain of the output amplifier is reduced by a factor of 4. This is done by Setting R1 to 39kΩ.Of the stereo headsets tested, it was found that 32Ω was a common impedance for each earpiece. For a stereo headset where two speakers are being driven in parallel this would be equivalent to driving a 16Ω load. This is out of the codec’s specification so a small headphone amplifier, U3, has been used on the evaluation board. This is not required if the impedance of the earpiece is equal or greater than 32Ω.The large 100 μF decoupling capacitors have been used so that the codec could be tested in its “high pass filter mode disabled” configuration. If you do not require a frequency response to go down below 300 Hz, then these capacitors can be reduced to small values. The main design consideration is the impedance should not be significant compared to the impedance of the headphone selected at frequencies of interest.E.g. if using a 32Ω headphone and expecting a 3dB point at 300 Hz, then the decoupling capacitor impedance could be 32Ω at 300Hz i.e. 10 μF. This requires a much smaller footprint than the 100μF used in the reference design.6.2 Driving the Headset Directly from the CodecThis will achieve the most cost effective design but care must be taken to ensure that the 32Ω specification of load is met by selecting an appropriate headset.Remove R10, R13 and R12. Fit R11, R9, R38 as zero ohm links. Fit 39kΩ in place of R1 to reduce the gain by 4.In-house testing showed that with a 32Ω load and with R1 set to 39kΩ, that there was some distortion at zero cross-over but that it was not easily perceptible.Even though the output signal level had been reduced by a factor of 4, on the headsets tested, the volume levels sounded loud enough for most applications. It is important to check this with the target headset for your application.6.3 Microphone CircuitThe microphone circuit is designed for an electret microphone (which is commonly used in PC applications). Typically this would be powered by 5V via a 2.2kΩ series resistor. In the reference design, it is powered by 3.3V to ensure a clean supply regardless of the power supply used to power the Dev kit. This reduces the sensitivity of the microphone - you should test your application with the microphone and voltage you intend to use in order to determine your component values.The gain of the microphone is set by R22 and R24, with gain being equal to R22/R24. The current values are 62K and 3.9K, giving a gain of approximately 16. When changing to a different gain, R27 and R25 should be set to the new values as well. This ensures that the load seen by common mode noise on the microphone is identical and prevents it from being amplified.R31 is a no fit resistor. It’s purpose is to facilitate test modes where a user wants to loop audio output directly back to the audio input to conduct an over the air audio test.6.4 SidetoneWhen we talk, we hear our own voice, which is part of normal speech perception. If our ears are covered by headphones, we do not hear our voice, which is perceived as abnormal. (Try covering your ears while talking to notice the difference).To compensate for the loss in feedback to the ear when it is covered with a headphone, most telephony systems inject some of the microphone signal back into the audio output path so that the person perceives their own speech as normal. This feature is commonly referred to as sidetone.Variable resistor VR2 allows you to control the amount of sidetone that is fed back to the audio output so that the user perceives their speech as normal.If the headset design does not totally cover the ear, then the sideband circuitry can be omitted.6.5 Power DownFor battery powered audio applications, the power down feature of the codec allows you to turn it off and save power when it is not being used. This feature can be tested by fitting R7 with a 0Ωlink and controlling the PUI input of the codec via MPIO_5.For AT commands, MPIO_5 translates to GPIO 7.The put GPIO 7 into output mode, use “ats610=$040”To turn the codec on, use “ats627=1”To turn the codec off, use “ats627=0”6.6 Alternative PCM_CLKSome applications require that the PCM Clock is driven by external circuitry. This requires the PCM Interface provided by the BISM to be put in Slave mode and a clock is supplied by the external circuitry on MPIO_7.Contact Ezurio for further details if this is a requirement.6.7 SwitchesThe switches S1, S2 and S3 have no defined function. They are there to assist you to prototype your audio application. e.g. If your application requires a button to be pressed for the user to answer an incoming connection, you can prototype that function using one of the switches provided.ATS620 allows you to read the status of the GPIO ports.No switches pressed: ATS620? => $0028S1 pressed (GPIO 9) ATS620? => $0128S2 pressed (GPIO 7) ATS620? => $0068S3 pressed (GPIO 8) ATS620? => $00A86.8 High Pass Filter EnableThe W681360 can have its High Pass filter enabled or disabled, depending on the state of the HB pin (Pin 16). This is pulled high or low by R3 or R4 (Default). See section 5.1 for more details.6.9 GPIO to MPIO MappingAT commands use GPIO numbers to represent I/O lines. These GPIO numbers map to physical signals drawn on the schematics as MPIO lines. Some of the GPIO/MPIO lines are used when providing a full RS232 interface.The following tables gives the mapping between GPIO, MPIO and RS232 signals.DCD MPIO_3RI MPIO_2DTR MPIO_9DSR MPIO_8GPIO_1 MPIO_0GPIO_2 MPIO_1GPIO_3 MPIO_9GPIO_4 MPIO_10GPIO_5 MPIO_11GPIO_6 MPIO_4GPIO_7 MPIO_5GPIO_8 MPIO_6GPIO_9 MPIO_7Note: For the BISM PA (Class 1 design), MPIO_0 and MPIO_1 are used to control the RF switch so are not available to the AT Command Set.7.

BRD4305E Block Diagram3.3 Radio Board Block Description3.3.1 Wireless SiPThe BRD4305E Mighty Gecko Radio Board incorporates an MGM13S12F512GA Mighty Gecko MGM13S12 module featuring 32-bit Cortex®-M4 with FPU core, 512 kB of flash memory, 64 kB of RAM and a 2.4 GHz band transceiver with output power up to 18 dBm. For additional information on the MGM13S12F512GA, refer to the MGM13S data sheet.3.3.2 LF Crystal Oscillator (LFXO)The BRD4305E Radio Board has a 32.768 kHz crystal mounted. For details regarding the crystal configuration, refer to Application Note "AN0016.1: Oscillator Design Considerations".3.3.3 UFL ConnectorTo be able to perform conducted measurements, Silicon Labs added a UFL connector to the Radio Board. The connector allows an external 50 Ohm cable or antenna to be connected during design verification or testing.Note: By default, the output of the matching network is connected to the printed inverted-F antenna by a series component. It can be connected to the UFL connector as well through a series 0 Ohm resistor, which is not mounted by default. For conducted measure-ments through the UFL connector, the series component to the antenna should be removed and the 0 Ohm resistor should be mounted (see section for further details).| Building a more connected world.Rev. 1.0 | 53.3.4 Radio Board ConnectorsTwo dual-row, 0.05” pitch polarized connectors make up the BRD4305E Radio Board interface to the Wireless Starter Kit Mainboard.

BRD4305E Bottom ViewMechanical DetailsRev. 1.0 | 7EMC Compliance 5. EMC Compliance5.1 IntroductionCompliance of the fundamental and harmonic levels of the BRD4305E Radio Board is tested against the following standards:• 2.4 GHz:•ETSI EN 300-328•FCC 15.2475.2 EMC Regulations for 2.4 GHz5.2.1 ETSI EN 300-328 Emission Limits for the 2400-2483.5 MHz BandBased on ETSI EN 300-328, the allowed maximum fundamental power for the 2400-2483.5 MHz band is 20 dBm EIRP. For the unwan-ted emissions in the 1 GHz to 12.75 GHz domain, the specific limit is -30 dBm EIRP.5.2.2 FCC15.247 Emission Limits for the 2400-2483.5 MHz BandFCC 15.247 allows conducted output power up to 1 Watt (30 dBm) in the 2400-2483.5 MHz band. For spurious emissions the limit is -20 dBc based on either conducted or radiated measurement, if the emission is not in a restricted band. The restricted bands are speci-fied in FCC 15.205. In these bands the spurious emission levels must meet the levels set out in FCC 15.209. In the range from 960 MHz to the frequency of the 5th harmonic, it is defined as 0.5 mV/m at 3 m distance which equals to -41.2 dBm in EIRP.Additionally, for spurious frequencies above 1 GHz, FCC 15.35 allows duty-cycle relaxation to the regulatory limits. For the EmberZNet PRO the relaxation is 3.6 dB. Therefore, the -41.2 dBm limit can be modified to -37.6 dBm.If operating in the 2400-2483.5 MHz band, the 2nd, 3rd, and 5th harmonics can fall into restricted bands. As a result, for those harmon-ics the -37.6 dBm limit should be applied. For the 4th harmonic the -20 dBc limit should be applied.5.2.3 Applied Emission Limits for the 2.4 GHz BandThe above ETSI limits are applied both for conducted and radiated measurements.The FCC restricted band limits are radiated limits only. In addition, Silicon Labs applies the same restrictions to the conducted spec-trum. By doing so, compliance with the radiated limits can be estimated based on the conducted measurement, by assuming the use of an antenna with 0 dB gain at the fundamental and the harmonic frequencies.The overall applied limits are shown in the table below.Table 5.1. Applied Limits for Spurious Emissions for the 2.4 GHz Band | Building a more connected world.Rev. 1.0 | 86. RF Performance6.1 Conducted Power MeasurementsDuring measurements, the BRD4305E Radio Board was attached to a Wireless Starter Kit Mainboard which was supplied by USB. The voltage supply for the Radio Board was 3.3 V.6.1.1 Conducted Measurements in the 2.4 GHz BandThe BRD4305E Radio Board was connected directly to a Spectrum Analyzer through its UFL connector (the was removed and a 0 Ohm resistor was soldered to the position). The supply for the module (VDD) was 3.3 V provided by the mainboard; for details, see the sche-matic of the BRD4305E. The transceiver was operated in continuous carrier transmission mode. The output power of the radio was set to 18 dBm.The typical output spectrum is shown in the following figure.Figure 6.1. Typical Output Spectrum of the BRD4305EAs shown in the figure, the fundamental is just a bit under 18 dBm and all of the unwanted emissions are under the -37.6 dBm applied limit.Note: The conducted measurement is performed by connecting the on-board UFL connector to a Spectrum Analyzer through an SMA Conversion Adapter (P/N: HRMJ-U.FLP(40)). This connection itself introduces approximately 0.3 dB insertion loss.Rev. 1.0 | 96.2 Radiated Power MeasurementsDuring measurements, the BRD4305E Radio Board was attached to a Wireless Starter Kit Mainboard which was supplied by USB. The voltage supply for the Radio Board was 3.3 V. The radiated power was measured in an antenna chamber by rotating the board 360 de-grees with horizontal and vertical reference antenna polarizations in the XY, XZ, and YZ cuts. The measurement planes are illustrated in the figure below.Figure 6.2. Illustration of Reference Planes with a Radio Board Plugged into the Wireless Starter Kit Mainboard Note: The radiated measurement results presented in this document were recorded in an unlicensed antenna chamber. Also, the radi-ated power levels may change depending on the actual application (PCB size, used antenna, and so on). Therefore, the absolute levels and margins of the final application are recommended to be verified in a licensed EMC testhouse.6.2.1 Radiated Measurements in the 2.4 GHz BandThe supply for the module (VDD) was 3.3 V provided by the mainboard; for details, see the BRD4305E schematic. The transceiver was operated in continuous carrier transmission mode. The output power of the radio was set to 18 dBm based on the conducted measure-ment.The fundamental was set to the frequency where the maximum antenna gain was measured. The results are shown in the table below. Note: The frequency in which the antenna gain has its maximum value can vary between modules due to the technological spreading of the passive RF components and the antenna.Table 6.1. Maximums of the Measured Radiated Powers in EIRP [dBm]As shown in the table, the level of the fundamental is 17 dBm. The strongest harmonic is the double-frequency one and it is compliant with the -37.6 dBm applied limit with 0.7 dB margin. | Building a more connected world.Rev. 1.0 | 10EMC Compliance Recommendations 7. EMC Compliance Recommendations7.1 Recommendations for 2.4 GHz ETSI EN 300-328 ComplianceAs shown in the previous section, the power of the fundamental frequency of the BRD4305E Mighty Gecko Radio Board with 18 dBm output is compliant with the 20 dBm limit of the ETSI EN 300-328 regulation in both the conducted and radiated measurements. The harmonic emissions are under the -30 dBm limit with large margin.7.2 Recommendations for 2.4 GHz FCC 15.247 ComplianceAs shown in the previous section, the power of the fundamental frequency of the BRD4305E Mighty Gecko Radio Board with 18 dBm output is compliant with the 30 dBm limit of the FCC 15.247 regulation. The harmonic emissions are under the -37.6 dBm applied limit.Board Revision History 8. Board Revision HistoryTable 8.1.

Laird Technologies Bluetooth模块开发套件说明书

Laird Wireless Development KitApplication NotePart # DVK-BT740-SA and DVK-BT740-SCApplicable to the following Bluetooth module part numbers: BT740-SA and BT740-SC1O VERVIEWLaird’s Wireless Development Kit provides a platform for rapid prototyping of wireless connectivity, providing options for the development of Bluetooth applications.This manual is for Rev. 03 of the development PCB, previously utilised in Laird part # BISDK02BI-02. IntroductionThe Laird Wireless Development Kit is designed to support the rapid development of applications and software for the latest range of Laird Class 1 Bluetooth modules. It is applicable to all of the BT740 series of modules, which includes module part numbers BT740-SA and BT740-SC. More information regarding these products is available from the Laird website:/Products/Embedded-Wireless-Solutions/Bluetooth-Radio-Modules/BT700-Series/BT740/ Package ContentsAll kits contain the following items:Development Board The motherboard is used to mount your chosen wireless module, providing the RS-232 interface and access to all the module interface pins.USB cable The USB cable can ONLY be used to provide power for the Dev Kit via the on-board connector. Serial cable RS-232 interface cable to provide communication between your host pc and your choice of wireless module. The serial cable can also be used to power the motherboard and module from pin 9.Bluetooth USB adapter Development Kit includes a free USB Bluetooth adaptor, Laird part # BRBLU03-010A0. This robust, Class 1 Bluetoothv2.0 Adapter has native support for Microsoft Bluetooth software stacks since Windows XP SP2.CB-BT740-SA ORCB-BT740-SCDepending upon the end DVK part number one of these carrier boards will be included. This issimply the small SMT Bluetooth module mounted onto a host PCB carrier board that terminates in a Hirose 40 pin connector on its base to allow simple, removable connectivity to the matingDevelopment Motherboard. This may not be bought alone and is for evaluation purposes ONLY.Note: The Carrier Board inverts the Reset logic generated on the Development board (to Active high for Reset).EZURiO / Laird Terminal application PC-based terminal emulation software, specifically designed to help the development and diagnostics of applications on the Laird range of modules. Web link Card for Documentation Instructions on the web links to download extensive documentation including Development Kit user guide, board design circuit diagrams, User Manuals and quick start guides and product videos. External AntennaExternal antenna only supplied with DVK-BT740-SC development kit.2W IRELESS M ODULED EVELOPMENT B OARDThe development board allows the Laird Bluetooth Module to be connected to a PC. The development board providesRS-232 level conversion through a standard 9-way D type connector to all pins of the 40-way Hirose connector supplied on the Carrier Board that the BT73O series module is soldered onto.3 G ETTING TO KNOW THE D EVELOPMENT B OARDFigure 1: Development Board50-way connector(Not required for Bluetooth) modules)RS-232 Level ShifterPSU Options:or RS232 Pin 9Reset SwitchPCM Output – not available on BT740 series4P OWER S UPPLYMinimum Typical MaximumInput Voltage 3.6V 5V 6VThe development board provides a number of options to provide power to the module:▪5V Power from a USB port▪Power from an external power supply via screw terminals▪Power from an external mains power block via a 2.1 mm DC connector▪Power via Pin 9 of the RS232 adaptorThe developer kit includes a USB cable to provide power to the development board. This should be plugged into a PC USB port, a USB hub, or a mains adaptor with a USB output. If a hub is used, it should be a powered USB hub to ensure that sufficient current is available at the port being used. The BT740 series modules can be driven by the current available at a USB port.Jumper JP2 is used to select an external power source on the screw terminals.Note: MC55 Supply is not for use with the BT740 – this relates to a legacy use of the Development Motherboard only.Figure 2: JP2 SettingsSW1 (slide switch) provides the power on/off for the module but does not isolate the power from other components of the development board.S1 (push button TACT switch) provides a reset signal to both the 40- and 50-way connectors. Note that the reset polarity is different for the 40- and 50-way pinouts. This is accomplished by circuitry on the development board, providing an active HIGH reset for the 40-way connector and an active LOW for the 50-way connector. Users connecting a reset signal to the test points on the board should be aware that there is a 10kΩ pulldown on the 40-way reset pin and an open collector transistor connected to the 50-way reset pin. Refer to the schematics available for download from the Documentation tab at /Products/Embedded-Wireless-Solutions/Bluetooth-Radio-Modules/BT700-Series/BT740/ Note: The 50-way connector is not used for Bluetooth modules.An alternative method of powering the development kit is to supply power to Pin 9 of the RS-232 connector. If this method is used, no other power supplies should be connected to the board. Pins 2 and 3 of Jumper 8 on the development board need to be connected to allow power to be derived from pin 9 of the serial port. In this mode the ring indicator is not available from the RS-232 interface. Note that J8 is fitted with a wire link in the default position. This must be removed and replaced with a jumper or wire link to enable Pin 9 power.Figure 3: J8 Settings5RS-232S ERIAL I NTERFACEThis provides a direct interface to any standard RS-232 port on a PC or peripheral. The 9-way D type connector can be plugged straight into a serial port on a PC or peripheral. If access to the serial port is restricted, the serial cable provided can be used to connect the development board to the PC.The development board contains a level shifter on the RX, TX, CTS, RTS, DTR, DSR, RI, and DCD signals that converts between the 3.3 V levels required on the module to the standard RS-232 levels.The level shifter can have its outputs permanently enabled or enabled only when the module is active (i.e., not in sleep mode). The latter is useful when a defined state is required at the RS-232 interface as the module enters and exits its low power modes. The behaviour is determined by the setting of J10 which is located behind the USB socket at the rear of the board. The normal setting is Always Enabled.Figure 4: J10 SettingsIf digital signal levels are required at the RS-232 connector, these can be achieved by removing the level shifter and populating the PCB pads that are then exposed with zero ohm links.6S OFTWAREThe development board connects the Carrier Board housing the BT740 series module to the serial port of a PC or other device. From a PC you can communicate with the module using any Terminal Emulator software such as HyperTerminal, Procomm, or the EZURiO / Laird Terminal application supplied.Standard SettingPin 9 PowerEZURiO Terminal is a terminal emulation application capable of running on Windows 98, Me, 2000, XP, Windows 7and Windows 8 operating systems. It was developed specifically to aid development and testing of Laird modules. It allows connection to serial devices using any combination of the communications parameters listed in Table 1.Table 1: Communication ParametersCOM Port: 1 to 255Baud rate: 300 to 921600Parity: None, Odd, EvenData Bits: 7 or 8Stop Bits: 1 or 2Handshaking: None or CTS/RTSThe benefits of using EZURiO / Laird Terminal are:▪Status of DSR, CTS, DCD, and RI are continuously displayed▪DTR on the host PC can be directly controlled via a check box▪RTS can be directly controlled▪BREAK signals can be sent▪Scripts can be run to assist▪Additional built-in features speed developmentLaird includes a “Data Transfer Test” mode allowing data to be sent as fast as the handshaking permits. This feature is useful for testing the bit transfer rate of a Bluetooth connection.The EZURiO / Laird Terminal application is available from our website at the link below and thenDocumentation tab:-/Products/Embedded-Wireless-Solutions/Bluetooth-Radio-Modules/BT700-Series/BT740/ 7I NTERFACE S PECIFICATION7.1Serial port connectorThe pin-out for the 9-way D type connector is shown in Table 2.Note: The direction is as seen from the module’s perspective.Table 2: Pin DefinitionsPin Description Signal Direction1 Data Carrier Detect DCD Output2 Transmit Data TD Output3 Receive Data RD Input4 Data Set Ready DSR Input5 Ground GND ---6 Data Terminal Ready DTR Output7 Clear To Send CTS Input8 Request To Send RTS Output9 Board Power or Ring Indicator RI or Power Output7.2Module Breakout ConnectorsAll of the pins from the 40-way connector are available on the two rows of plated through holes on the long sides of the board. These translate directly to the pin layout of the module receptacles, allowing access to all of the module pins. Pin 1 is indicated by an indent on the silk screen.The format of the holes allows the fitting of your choice of connectors, or they can be used for directly soldering test wires to the board. Both are laid out on a standard 2.54 mm (0.1 inch) pitch.7.3Board Configuration JumpersTable 3: JumpersJumper DescriptionJP1 Breaks the supply to the module for current measurementsJP2 Selects external power supply for Siemens modulesJP8 Selects pin 9 power (fitted as wire link)J10 Selects low power mode for RS-232 level shifter8O THER F EATURES8.1Power Consumption MeasurementA removable jumper JP1 is provided to break the supply line directly to the modules, allowing the current consumption to be measured. For normal operation JP1 must be fitted.Note: This only measures the current consumption of the module, and not of the level shifter or other peripheral circuitry.8.2USB AccessUSB access can be provided to allow a direct USB connection to a Bluetooth HCI module. To do this fit resistor pads R17 and R18 on the development kit with zero Ohm links.Note that if this is done and the unit is then connected to a USB host port, it will be powered from that same port. Do not attempt to use any other power source for the development kit when operating in this mode.This is not relevant for modules with a UART interface.CONN-APPNOTE-BT740-DVK-0813Copyright © 2013 Laird Technologies, Inc.

This allows the router to update the firmware of the cellular module automatically. Only the firmware of the cellular module is updated (not the firmware of the router). The FOTA user module is easy to use – it can be activated with just one checkbox. The router must be connected to the Internet in order to use FOTA updates. The connection to the server with firmware files provided is already defined in the FOTA user module, but it is possible to enter your own server credentials. The FOTA user module checks for the new cellular module firmware every 24 hours. It is also possible to check for new cellular module firmware manually.FOTA user module operationThe FOTA user module is NOT part of the standard router firmware. Th e FOTAuser module is available for OWL LTE and OWL LTE M12.12.INSTALLATION USER MODULE2.Install ation of the FOTA user modulee the web interface for installing the FOTA user module. Enter your userpasswordname and Array2.Select User Modules item in the Customization section3.Select the file of the FOTA user module and click on Add or Update button32.INSTALLATION USER MODULE3.UPDATE CELLULAR MODULE FIRMWARE 3.Update of the cellular module firmwareThere are 2ways of updating the cellular module firmware:Automatic u pdate:Use the automatic update as standard option.For detailed information see chapter "3.1. Automatic u pdate".Manual u pdate: Use this option only if is explicitly described in theR elease Information.For detailed information see chapter "3.2. Manualu pdate".43.1.Automatic u pdateIn this chapter, the configuration of the FOTA user module is described. Go to the Automatic Update page in the Configuration section. To enable the FOTA user module, tick the Enable automatic update checkbox and click Apply. The other configuration items are described in the table below. The behavior of the FOTA user module is described on the next page.Item DescriptionEnable automatic update Enable s the FOTA user module. There is a presetconnection to the server with up to date firmwareinformation.URL Optional. Fill in a different server address where theJSON file with firmware information is stored, along withfirmware files.Username Optional. Specify only if you have specified URL. Thepreset username for the preset server is saved in theFOTA user module.Password Optional. Specify only if you have specified URL. Thepreset password for the preset server is saved in theFOTA user module.Apply Conﬁguration changes will take effect after pressing the Ap-ply button.Start Manually Press this button to check manually for a new cellularmod-ule firmware. Otherwise, a check for updates takesplace every 24 hours at the same time that the FOTA usermodule was first enabled.5Behavior of the FOTA u ser m oduleWhen the FOTA user module is enabled, it will connect to the preset server to check for new firmware updates of the cellular module and of the FOTA user module. It is then done every 24 hours at the same time the FOTA user module was enabled. You can also run this firmware update check manually using the Start Manually button.This file is in JSON format, complete – with cellular module names, associated firmware revision numbers and links to firmware files. The FOTA user module will download this file and compare it to the current firmware revision number. If there is new firmware available(higher revision number), the firmware file for the cellular module is downloaded. The router needs a stable connection and power supply to download the firmware file properly. If the downloading of the firmware fails, the FOTA user module will recognize the incomplete file when next attempting to download the firmware file. It will then continue to download the rest of the file – it does not unnecessarily download duplicate data again.The FOTA user module will regularly check for new firmware updates of the cellular module and the of FOTA user module when it is connected to the Internet (it does not matter which interface is used). The preset server address, username and pass-word are saved in the FOTA user module, so there is no need to fill-in credentials unless you want to use another server.63.2. Manual u pdateIt is strongly recommended to double-check the firmware to be uploaded to the cellular m odule.If the firmware is not intended for a cellular module used in thisrouter,uploading m ay irretrievably dam age the device.Firmware u pdate is at your own risk!Use this option only if is explicitly required in the R elease Information.3.2.1F irmware CompatibilityChoos e the cellular module firm ware according to the information given in theR elease Information.73.2.2.Step-by-step Manual u pdatee the web interface for installing the FOTA-manual user module.

Frame Synchronization
The ET12 supports both short- and long-frame synchronization in both master and slave modes. In short frame synchronization mode, the frame synchronization signal is an active-high pulse at the audio frame rate that is a single-bit period in width and is synchronized to the rising edge of the bit clock. The PCM slave looks for a high on the falling edge of the bit clock and expects the first bit of the first slot to start at the next rising edge of the clock. In long-frame synchronization mode, the frame synchronization signal is again an active-
high pulse at the audio frame rate; however, the duration is three-bit periods and the pulse starts coincident with the first bit of the first slot.
Data Formatting
The ET12 may be configured to generate and accept several different data formats. For general use, PCM interface is configured as below:
PCM_BCLK=512KHZ
PCM_SYNC=8KHZ
PCM_A mode (Short Frame Sync), Master mode, check the timing below.

如下图，其中0xFFE1为主服务，0xFFE2为读Notify，0xFFE3为写Write，如果往0xFFE3上写，模块串口（PUART）上会出现对应信息输出。

串口输出的数据格式为：+DATA:00,<data Length>\r\n<data…>
串口输入的数据格式为：AT+DATA=00,<data Length>\r\n<data…>
十一.模块参考PCB封装尺寸（单位：mm）
十三.参考炉温曲线
1.参考IPC / JEDEC标准。

2.峰值温度：<250°C；基于上述回流焊（条件），最多允许回流焊次数：2次。

3.建议在回流过程中添加氮气（N2）以实现2000ppm或更低的氧气浓度。

4.MSL=4，湿敏元件；如果超过保质期，请确保烘烤步骤以去除组件中的水分。
