The normal calibration interval is once per year.Chapter 3 Functional DetailsExternal componentsThe OM-USB-3101 has the following external components, as shown in Figure 2.▪Screw terminals▪LED indicators▪USB connector1 Screw terminal pins 1 to 28 4 Power LED2 Screw terminal pins 29 to 56 5 USB connector3 Status LEDFigure 2. OM-USB-3101 external componentsUSB connectorThe USB connector provides power and communication. The voltage supplied through the USB connector is system-dependent, and may be less than 5 V. No external power supply is required.LED indicatorsThe OM-USB-3101 has two LED indicators –Status and Power.▪The Status LED indicates the communication status of the OM-USB-3101. It blinks when data is being transferred, and is off when the OM-USB-3101 is not communicating. This LED uses up to 10 mA ofcurrent and cannot be disabled.▪The Power LED turns on when the device is connected to a USB port on a computer or an external USB hub connected to a computer.Screw terminalsThe screw terminals on the bottom edge of the OM-USB-3101 provide the following connections:▪Four analog voltage outputs (VOUT0, VOUT1, VOUT2, VOUT3)▪Eight digital I/O (DIO0 to DIO7)▪One digital I/O pull-down resistor connection (DIO CTL)▪One SYNC I/O terminal for external clocking and multi-unit synchronization (SYNCLD)▪One counter input (CTR)▪One power output (+5 V)▪Analog ground (AGND) and digital ground (DGND) connectionsFigure 3. OM-USB-3101 signal pinoutUse 16 AWG to 30 AWG wire gauge when making screw terminal connections.Signal connectionsAnalog voltage outputsThe screw terminal pins labeled VOUT0 to VOUT3 are voltage output terminals. The voltage output range for each channel is software-programmable for either bipolar or unipolar. The bipolar range is ±10 V, and the unipolar range is 0 to 10 V. The channel outputs may be updated individually or simultaneously.Digital I/OYou can connect up to eight digital I/O lines to DIO0 through DIO7. Each digital channel is individuallyconfigurable for input or output. The digital I/O terminals can detect the state of any TTL-level input. Refer to the schematic shown in Figure 4.Figure 4. Schematic showing switch detection by digital channel DIO0 If you set the switch to the +5 V input, DIO0 reads TRUE (1). If you move the switch to DGND, DIO0 reads FALSE (0).DIO control terminal (DIO CTL) for pull-up/down configurationAll digital pins are floating by default. When inputs are floating, the state of unwired inputs are undefined (they may read high or low). You can configure the inputs to read a high or low value when they aren’t wired. Use theDIO CTL pin to configure the digital pins for pull-up (inputs read high when unwired) or pull-down (inputs read low when not wired).▪To pull up the digital pins to +5V, wire the DIO CTL terminal pin to the +5V pin.▪To pull down the digital pins to ground (0 volts), wire the DIO CTL terminal pin to a DGND pin. Synchronous DAC loadThe synchronous DAC load terminal (SYNCLD) is a bidirectional I/O signal that allows you to simultaneously update the DAC outputs on multiple devices. You can use this pin for two purposes:▪Configure as an input (slave mode) to receive the D/A LOAD signal from an external source.When the SYNCLD pin receives the trigger signal, the analog outputs are updated simultaneously.▪Configure as an output (master mode) to send the internal D/A LOAD signal to the SYNCLD pin.You can use the SYNCLD pin to synchronize with a second OM-USB-3101 and simultaneously update the DAC outputs on each device. Refer to Synchronizing multiple units section below.Use InstaCal to configure the SYNCLD mode as master or slave. On power up and reset the SYNCLD pin is set to slave mode (input). Refer to the "USB-3100 Series" section in the Universal Library User's Guide for information on how to configure the OM-USB-3101 with the Universal Library.Synchronizing multiple unitsYou can connect the SYNCLD terminal pin (pin 49) of two OM-USB-3101 units together in a master/slave configuration and simultaneously update the DAC outputs of both devices. Perform the following procedure:1.Connect SYNCLD on the master OM-USB-3101 to the SYNCLD pin on the slave OM-USB-3101.2.Configure SYNCLD on the slave device for input to receive the D/A LOAD signal from the master device.Use InstaCal to set the direction of the SYNCLD pin.3.Configure SYNCLD on the master device for output to generate an output pulse on the SYNCLD pin.Set the Universal Library SIMULTANEOUS option for each device. Refer to the Universal Library User's Guide for information on how to configure the OM-USB-3101 with the Universal Library. When the SYNCLD pin on the slave device receives the signal, the analog output channels on each device are updated simultaneously. Counter inputThe CTR terminal is a 32-bit event counter that can accept frequency inputs up to 1 MHz. The internal counter increments when the TTL levels transition from low to high.Power outputThe +5V terminal can output up to 10 mA maximum. You can use this terminal to supply power to external devices or circuitry.Caution!The +5V terminal is an output. Do not connect to an external power supply or you may damage the device and possibly the computer.GroundThe analog ground (AGND) terminals provide a common ground for all analog voltage output channels.The digital ground (GND) terminals provide a common ground for the digital, counter, and sync terminal and the power terminal.Chapter 4 SpecificationsTypical for 25 °C unless otherwise specified.Specifications in italic text are guaranteed by design.Analog voltage outputTable 1. Analog voltage output specificationsNote 1: The OM-USB-3101 output voltage level defaults to 0V whenever the output voltage range is reconfigured.The OM-USB-3101 output voltage level will also default to 0V:1) Whenever the host PC is reset, shut down or suspended.2) If a reset command is issued to the device.Note 2: The duration of this particular output transient is highly dependent on the enumeration process of the host PC. Typically the output of the USB-3101 is stable after 2 secondsNote 3: The maximum differential non-linearity specification applies to the entire 0 to 70 °C temperature range of the OM-USB-3101. This specification also accounts for the maximum errors due to the softwarecalibration algorithm (in Calibrated mode only) and the DAC8554 digital to analog converter non-linearities.Table 2. Absolute accuracy specifications – calibrated outputTable 3. Absolute accuracy components specifications – calibrated outputTable 4. Relative accuracy specificationsAnalog output calibrationTable 5. Analog output calibration specificationsDigital input/outputTable 6. Digital I/O specificationsNote 4: Pull up and pull down configuration area available using the DIO CTL terminal block pin 54. The pull down configuration requires the DIO CTL pin (pin 54) to be connected to a DGND pin (pin 50, 53 or55). For a pull up configuration, the DIO CTL pin should be connected to the +5V terminal pin (pin56).Synchronous DAC LoadTable 7. SYNCLD I/O specificationsNote 5: SYNCLD is a Schmitt trigger input and is over-current protected with a 200 Ohm series resistor.Note 6: When SYNCLD is in input mode, the analog outputs may either be updated immediately or when a positive edge is seen on the SYNCLD pin (this is under software control.) However, the pin must be ata low logic level in order for the DAC outputs to be updated immediately. If an external source ispulling the pin high, no update will occur.CounterTable 8.

The Radio provides two-way FM communication on up to 28 channels, over a frequency range of 136 to 160 MHz, with an RF output of 3 watts.This synthesized portable utilizes a microprocessor core allowing features and performance designed to meet the requirements of a commercial NDI NSUR as detailed in the Purchase Description, AN/PRC-127(A) Radio Set. Using the information in this manual will help assure optimum and proper performance from the Radio.The Radio Set consists of the EPI 3101A Radio and the following accessory items: LAAO126 Rechargeable Nickel-Cadmium Battery (2), LAA0312A Battery Charger, LAA0117 Battery Holder for 9 replaceable AA batteries, LAA0818A Flexible Antenna, LAA0203A External Speaker/ Microphone and LAA0445A Carrying Case. All of these items, except for the Radio, are shown on page 27.EPI 3101A User’s Manual1PREPARATION FOR USEKEYBOARD/DISPLAY COVERTo remove or install the Keyboard/Display Cover, remove the battery if installed. The Cover slides in grooves and latches at its bottom edge. BATTERY INSTALLATIONA.Battery packs are available as a rechargeable type (LAA0126) oras a non-rechargeable type (LAA01 17). Rechargeable battery packs can be charged separately or while attached to a radio.NOTE: For safety reasons, rechargeable battery packs are shipped uncharged or only partially charged. Therefore, a recharge-able battery pack should be properly charged before use.B.To install the battery pack, locate the center hub on the radio baseand place it in the recess of the battery pack. Position the pack at the 30” offset, seating two metal studs in their recess. Apply upward pressure to the pack while twisting the pack to its original position.The metal tab will click, locking the pack in position.C.To remove the battery pack, first turn the radio off. Then, as shownabove, push up the metal tab on the side of the case while twisting the battery pack approximately 30° and remove it from the radio.NOTE: All information programmed into the radio is maintained even when the battery pack is removed.D.Periodically check the contacts on the battery pack for dirt that mayprevent a good electrical contact with the charging base.WARNING:Do not dispose of a battery pack in fire.An explosion may occur.ANTENNA INSTALLATIONInsert the flexible helical-wound antenna (LAA0818A) into the Unit’s antenna connector and turn it clockwise until it is firmly seated.27-SEGMENT LIQUID CRYSTAL DISPLAYSPEAKERM I C R O P H O N ELCD DISPLAYK E Y B O A R D EPI 3101A User’s Manual3BASIC OPERATIONTRANSMITFunction - Used only in Programming ModeClear (Erase) - Used in Operational andSQUELCH CONTROLRotate the Squelch Control (CG-SQ) Knob clockwise from its detent (CG) position in order to hear any transmissions, regardless if they are tone or digital coded or not. This, in effect,. is the Radio’s MONITOR position. Turning the Squelch Control further clockwise until “noise” is heard permits the Volume Control to be adjusted to a desired level, even though an actual signal is not present.CHANNEL GROUPS510411312213114SELECT A GROUPGROUP NUMBER The Channel Selector knob has 14 positions. The Radio has 28 channels which are separated into two “groups” of 14 channels each. Group 01 is factory programmed for narrow channel (12.5kHz) FM reception. Channel Group 02 is programmed for wide channel (25 kHz) FMreception. Use Group 02 for proper communicationwith the original AN/PRC-127 Radio.P RESS THE #KEY on the keyboard to display the current Channel Group number. If it isn’t the desired Group, proceed to the next step.P RESS A NUMBER KEYfor the new Group number.P RESS THE ENTKEY or wait about 5 seconds; the radio returns to normal operation for the newgroup, and the channel corresponding to theChannel Selector’s position is displayed in theLCD.If an invalid number is selected (05 for example)when selecting a Channel Group, the LCD displaysnogrp05 (no Group 05) immediately if ENT ispressed, or in about 5 seconds if not pressed.Then, after 5 seconds, the radio returns to thepreviously selected group.6Rotate the Channel Selector knob to the desired channel. Please note that not all 14 channels may be programmed. Therefore, select only an authorized (programmed) channel for communication purposes.PTT SWITCHChCODE GUARD OPERATIONCode GuardTM, Tone or Digital, allows one radio or group of radios to be selectively called within a system. If the radio has been programmed with Code Guard, use the following receive and transmit instructions. CODE GUARD RECEIVETURN POWER ON by turning the Volume knobclockwise past the OFF detent.S ELECT A C ODE G UARD CHANNEL by turning theChannel Selector knob.A DJUST VOLUME by turning the Squelch knobclockwise until a rushing noise is heard, thenturning the Volume knob to a comfortable level.S ET C ODE G UARD MODE by turning the Squelchknob completely counterclockwise, past the detentto the CG position. A message will be heard onlywhen the proper Code Guard value is received.CODE GUARD TRANSMITT URN THE S QUELCH KNOB clockwise, off the detent.M ONITOR THE C ODE G UARD CHANNEL beforetransmitting.P RESS THE PTT (Push-To-Talk) switch if thechannel is not busy (signal is not present). Whenthe transmitter is activated, the LCD goes blank.R ESET THE S QUELCH KNOB to the Code Guardposition (CG) to receive only the messages withthe proper Code Guard value. During extendedtransmissions the squelch can be left open (offthe detent) until the exchange has ended.Code Guard is a trademark of BK Radio, Inc.8PROGRAMMINGThere are three different ways to program an EPI 3101A radio:A.It can be programmed and/or reviewed using its internal keyboard.This section of the manual describes that procedure.B.Another radio (MASTER) with the desired information can transferits programmed settings to the radio (SLAVE) by using a cloning cable, LAA0700. See “Cloning” on page 23.C.It can be programmed from a computer by using a special RS-232interface cable. That procedure is not described in this manual.See page 26 for more details.PROGRAMMING - KEYBOARD METHODRadios are shipped with a removable door covering the keyboard and display. Before programming or reviewing, remove the door. First, remove the battery pack if installed. Then, engaging the door just below the speaker grill, slide the door downward. Reinstall the battery pack. Make sure the battery pack is charged.1.Turn the radio on.2.Select the Channel Group to beprogrammed or reviewed.3.Press and hold the FCN key. Afterapproximately three seconds, the LCD willdisplay ---Id.4.Release the FCN key. The radio is now inthe password entry mode.5.Enter the six-digit Password Code.IMPORTANT: VVithout the correct PasswordCode, you cannot proceed with reviewingor programming. The same PasswordCode is used for both Channel Groups.New radios shipped from the factory areassigned the Password Code 000000.While entering the Password Code, thedisplay will not change, but a beep willsound for each key pressed. If thePassword Code is entered incorrectly, theradio will reset to normal operation. Tryagain, starting at step 3.EPI 3101A User’s Manual96.To keep the Password Code unchanged,press the ENT key and continue with normalradio programmingTo change the Password Code, press theFCN key and enter a new six-digit passwordcode. The’digits are now displayed as youenter them. The Password Code cancontain the digits 0 through 9, *, and #. The* is represented as a b and the # isrepresented as an A in the display.IMPORTANT: Do NOT use a 1 for the first digitof the Password Code - the radio willmalfunction. It will then require using acomputer program to correct the PasswordCode and put the radio back into normaloperating condition.If you make an errorwhile entering the newPassword Code, press the CLR key andtry again.7.Press the ENT key to store the newPassword Code and proceed to theprogramming mode. The display willchange to PROG Ch 0. The Radio is nowready for Reviewing and/or Programming. TO REVIEW GENERAL RADIO PERFORMANCE VARIABLES (CHANNEL 0):Channel 0 is the portion of the program that controls the general performance variables for each Group of 14 channels in a 28-channel radio. Thus, the Channel 0 settings for each Channel Group must be reviewed or programmed separately.NOTE: Settings listed as Group One Functions and Group Two Functions refer to reviewing or programming Function Groups,not the two Channel Groups 01 and 02.10Channel 0 Settings for each Channel Group include:Factory ProgramD e s c r i p t i o n Setting D i s p l a yID or Automatic Number Identification (ANI)’12345671234567 Transmit Timeout Timer disabled0 sec.

However, since most systems adhere to the Electronic Industry Association (EIA) standards, tones should be selected from the following EIA list.In order to insure optimum performance tone selection for use on the same radio frequency (RF) channel or adjacent channels in the same coverage area should be made from one of the Groups A, B, or C as much as possible. RELM guarantees optimum receiver performance only if tone frequencies below 220 Hz are chosen.GROUP A GROUP B GROUP C67.0 77.0 88.5 *100.0 107.2 114.8 123.0 131.8 141.3*151.471.9146.274.4 162.282.5156.779.7 173.894.8167.985.4 186.2103.5“179.991.5 203.5100.9192.8218.1*118.8210.7233.6127.3225.7250.3136.5241.8*50/60 Hz power distribution systems could cause falsing.The assignments in a given area shall be made from one of the Groups A, B, or C as much as possible.EPI 3101A User’s Manual21SELECTING A DIGITAL CODE GUARDCodes for the Digital Code Guard system (CDCSS) may be chosen from the following list. For the performance or compatibility of Digital Code Guard systems, it is recommended that an operational test be made on the intended system before wholesale assignments are made.In some cases, either one or both the transmit and receive codes will require an inverted code* to operate with existing systems. This can be done during the code programming of the system.Usually, systems using direct unit to unit transmission (systems without mobile relays, repeaters, remote control, etc.) may use codes from the table. Systems with relays, etc. may use code variations for system control and operational efficiency. The system operator or engineer should be consulted regarding the operational requirement on such systems.023065 131 172 251 331 412 466 612 703 025071132 174 261 343 413 503 624 712 026072 134 205 263 346 423 506 627 723 031073 143 223 265 351 431 516 631 731 032074 152 226 271 364 432 532 632 732 043114 155 243 306 365 445 546 654 734 047115 156 244 311 371 464 565 662 743 051116 162 245 315 411 465 606 664 754 054125 165*NOTE: Inverted code is displayed with a "-" following the Digital Code’s value.

Improper connectionB.Failure to power up CLONEC.CLONE set in the programmingmodeNOTE: To stop the FAIL mode,press CLR, power down both radiosand try again, starting at step 1 onpage 23.24SPECIAL CLONING INSTRUCTIONSIt is possible to change Channel 0 values on the MASTER radio, hold them in a temporary memory, and download them to the CLONE without actually entering them into the permanent memory of the MASTER. This is convenient if sequential identification numbers are used to identify a series of portables in a radio system. Assuming that the frequencies,Code Guard values, and other CH 0 values are common for all radios in the system, but that the radio identification number should be unique to each radio, the following method would be used to clone additional radios for the system:123456Program the MASTER with allfrequencies, Code Guard values andChannel 0 values that will becommon to all radios.Advance the display to show theMASTER’s ID number (for example100)Press CLR; press 1,2, and 5.125 isnow only in temporary memory.Press *, connect the cloning cable tothe CLONE radio and download bypressing FCN. ID number 125 isnow stored in permanent memory ofthe CLONE.After download, press CLR.Disconnect the CLONE. TheMASTER radio display will showthat 125 is still being held in thetemporary memory of the MASTER.Press PRI. This will increment theID number one digit to 126.NOTE: Any new number can be entered at this point by pressingCLR and using the digit keys toenter the new number.EPI 3101A User’s Manual 257.Press *.

➢ 在会议进行过程中，尽量控制会场噪音，不要在会场中随意走动。
MIC发言注意事项
➢ 发言时，不必手持MIC，距MIC 0.5-2m以内为佳。 ➢ 会议开始前，应固定好MIC的位置。MIC尽量远离有噪音发出的设备，并
且尽量使发言人能正对MIC，这样采集的声音质量更高，声音效果更好。
➢ 会议过程中，特别是本地有人发言时尽量不要移动MIC，因为Polycom的全向MIC灵敏度很高，发言时移动MIC会出现很大的噪音。

诊断功能
• 音频测试，可以在本地对麦克风和扬声器进行回环测试，以判断发送和接收音频是否正常。
➢ 会议过程中，不需要发言的会场要主动将本地会场的MIC关闭，保证会场安静。当需要发言时要及时打开MIC。
➢ 会议过程中，需要发言讨论时，先打开MIC向主会场提出请求，得到同意后再继续发言，否则请继续保持静音。
➢ 发言时，要一个人一个人的发言，不要多人同时讲话。因为全向MIC会把所有人的声音混合，远端听到的声音会非常嘈杂，听不清具体说话内容。
