1A镍氢电池充电管理IC-CN3085规格书

睡眠模式
CN3085内部有睡眠状态比较器，当输入电压VIN小于电池端电压＋10mv时，充电器处于睡眠模式；只有当输入电压VIN上升到电池端电压60mv以上时，充电器才离开睡眠模式，进入正常工作状态。
涓流充电状态
如果FB管脚电压低于0.84V，即电池电压低于电池端最高电压的69.4%，则CN3085处于涓流充电状态，充电器以恒流充电电流的28.8%对电池进行充电。

恒流充电状态
当FB管脚电压在0.84V和1.133V之间时，即电池电压在电池端最高电压的69.4%和93.2%之间，，则CN3085 处于恒流充电状态。充电电流公式为： ICH = 1216V / RISET 其中，ICH 表示充电电流，单位为安培 RISET 表示ISET管脚到地的电阻，单位为欧姆例如，如果需要1安培的充电电流，则： RISET = 1216V/1A = 1.22kΩ 为了保证良好的稳定性和温度特性，RISET建议使用精度为1%的金属膜电阻。

的28.8%；当FB管脚电压在0.84V和1.133V之间时，即电池电压在电池端最高电压的69.4%和93.2%之间，充电器采用恒流模式对电池充电，充电电流由ISET管脚和GND之间的电阻确定；当FB管脚电压大于 1.133V时，即电池电压大于电池端最高电压的93.2%时，CN3085处于维持充电状态，维持充电电流为恒流充电电流的28.8%，如果FB管脚电压达到1.216V，即电池电压接近电池端最高电压时，电池电压不再上升，充电电流逐渐减小。在维持充电阶段，内部定时器启动，维持充电时间由第6管脚的电阻和电容决定 (图1中的R5和C1)，当定时结束时，整个充电过程结束。在充电结束状态，当FB管脚电压下降到1.053V时，即电池电压下降到电池端最高电压的86.6%时，CN3085进入再充电状态，开始新的充电周期。当输入电压掉电或者输入电压低于电池电压时，充电器进入低功耗的睡眠模式，电池端消耗的电流小于3uA，从而增加了待机时间。上述充电过程如图3所示：

Switch Controller 1Track ID: JATR-3375-16 Rev. 1.0 1.General DescriptionThe RTL8305NB is a 5-port 10/100M Ethernet switch controller that integrates memory, five MACs, and five physical layer transceivers for 10Base-T and 100Base-TX operation into a single chip.In order to accomplish diagnostics in complex network systems, the RTL8305NB provides a loopback feature in each port.The RTL8305NB supports several advanced QoS functions with four-level priority queues to improve multimedia or real-time networking applications, including:•Multi-priority assignment•Differential queue weight•Port-based rate limitation•Queue-based rate limitationThe RTL8305NB supports 16 VLAN groups. These can be configured as port-based VLANs and/or 802.1Q tag-based VLANs. The RTL8305NB also supports VLAN learning, with four Independent VLAN Learning (IVL) filtering databases.The RTL8305NB contains a 2K-entry address lookup table. A 4-way associative hash algorithm avoids hash collisions and maintains forwarding performance.Maximum packet length can be 2048 bytes. Three types of independent storm filter are provided to filter packet storms, and an intelligent switch engine prevents Head-of-Line blocking problems.The RTL8305NB supports Energy-Efficient Ethernet mode (EEE; defined in IEEE 802.3az) to minimize system power consumption. Energy-Efficient Ethernet (EEE) supports Low Power Idle Mode. When Low Power Idle Mode is enabled, systems on both sides of the link can disable portions of the functionality and save power during periods of low link utilization.To simplify the peripheral power circuit, the RTL8305NB integrates one LDO regulator to generate 1.0V from a 3.3V input power, and needs only one external diode.Single-Chip 5-Port 10/100Mbps Ethernet Switch Controller2Track ID: JATR-3375-16 Rev. 1.02.

Basic Function Descriptions7.1. Switch Core Function Overview 7.1.1. Flow ControlThe RTL8305NB supports IEEE 802.3x full duplex flow control, force mode full duplex flow control, and optional half duplex backpressure.7.1.1.1IEEE 802.3x Full Duplex Flow Control For UTP with auto-negotiation ability, the pause ability of full duplex flow control is enabled by internalregisters via SMI on a per-port basis after reset. IEEE 802.3x flow control’s ability is auto-negotiated between the remote device and the RTL8305NB. If the auto-negotiation result of the IEEE 802.3x pause ability is ‘Enabled’, the full duplex 802.3x flow control function is enabled. Otherwise, full duplex IEEE 802.3x flow control function is disabled.7.1.1.2Half Duplex Back PressureThere are two mechanisms for half duplex backpressure; collision-based or carrier-based.Collision-Based Backpressure (Jam Mode) If the buffer is ready to overflow, this mechanism will force a collision. When the link partner detects thiscollision, the transmission is rescheduled.The Reschedule procedure is: •The RTL8305NB will drive TXEN to high and send the preamble; SFD and a 4-byte Jam signal(pattern is 0xAA). The RTL8305NB will then drive TXEN to low •When the link partner receives the Jam signal, it will feedback a 4-byte signal (pattern is CRC^0x01),it will then drive RXDV to low •The link partner waits for a random back-off time then re-sends the packet. The timing is shown inFigure 3Figure 3. Collision-Based Backpressure Signal TimingCarrier-Based Backpressure (Defer Mode)If the buffer is about to overflow, this mechanism will send an 0xAA pattern to defer the other station’s transmission. The RTL8305NB will continuously send the defer signal until the buffer overflow is resolved.7.1.2.Address Search, Learning, and AgingWhen a packet is received, the RTL8305NB will use the destination MAC address and FID to index the 2048-entry lookup table. If the indexed entry is valid, the received packet will be forwarded to the corresponding destination port. Otherwise, the RTL8305NB will broadcast the packet. This is the ‘Address Search’.The RTL8305NB then combines the source MAC address and the FID to index the 2048-entry lookup table. If the entry is not in the table it will record the source MAC address and add switching information. If this is an occupied entry, it will update the entry with new information when LRU is enabled. This is called ‘Learning’.Address aging is used to keep the contents of the address table correct in a dynamic network topology. The lookup engine will update the time stamp information of an entry whenever the corresponding source MAC address appears. An entry will be invalid (aged-out) if its time stamp information is not refreshed by the address learning process during the aging time period. The aging time of the RTL8305NB is between 200 and 400 seconds.7.1.3.Half Duplex OperationIn half duplex mode, the CSMA/CD media access method is the means by which two or more stations share a common transmission medium. To transmit, a station waits (defers) for a quiet period on the medium (that is, no other station is transmitting) and then sends the intended message in bit-serial form. If the message collides with that of another station, then each transmitting station intentionally transmits for an additional predefined period to ensure propagation of the collision throughout the system. The station remains silent for a random amount of time (backoff) before attempting to transmit again.When a transmission attempt has terminated due to a collision, it is retried until it is successful. A controlled randomization process called ‘truncated binary exponential backoff’ determines the scheduling of the retransmissions. At the end of enforcing a collision (jamming), the switch delays before attempting to retransmit the frame. The delay is an integer multiple of slot time (512 bit times). The number of slot times to delay before the n th retransmission attempt is chosen as a uniformly distributed random integer ‘r’ in the range:0 ≤ r < 2kwhere:k = min (n, backoffLimit). IEEE 802.3 defines the backoffLimit as 10.7.1.4.InterFrame GapThe InterFrame Gap is 9.6µs for 10Mbps Ethernet and 960ns for 100Mbps Fast Ethernet.7.1.5.Illegal FrameIllegal frames such as CRC error packets, runt packets (length < 64 bytes), and oversize packets (length > maximum length), will be discarded.Single-Chip 5-Port 10/100Mbps Ethernet Switch Controller 11Track ID: JATR-3375-16 Rev. 1.0Single-Chip 5-Port 10/100Mbps Ethernet Switch Controller 12Track ID: JATR-3375-16 Rev. 1.0 7.2.Physical Layer Functional Overview7.2.1.Auto-NegotiationThe RTL8305NB obtains the states of duplex, speed, and flow control ability for each port through the auto-negotiation mechanism defined in the IEEE 802.3 specifications. During auto-negotiation, each port advertises its ability to its link partner and compares its ability with advertisements received from its link partner. By default, the RTL8305NB advertises full capabilities (100Full, 100Half, 10Full, 10Half) together with flow control ability. The RTL8305NB also advertises the Energy Efficient Ethernet (EEE) capability to the link partner.7.2.2.10Base-T Transmit FunctionThe output 10Base-T waveform is Manchester-encoded before it is driven onto the network media. The internal filter shapes the driven signals to reduce EMI emissions, eliminating the need for an external filter.7.2.3.10Base-T Receive FunctionThe Manchester decoder converts the incoming serial stream to NRZ data when the squelch circuit detects the signal level is above squelch level.7.2.4.Link MonitorThe 10Base-T link pulse detection circuit continually monitors the RXIP/RXIN pins for the presence of valid link pulses. Auto-polarity is implemented to correct the detected reverse polarity of RXIP/RXIN signal pairs.7.2.5.100Base-TX Transmit FunctionThe 100Base-TX transmit function performs parallel to serial conversion, 4B/5B coding, scrambling, NRZ/NRZI conversion, and MLT-3 encoding. The 5-bit serial data stream after 4B/5B coding is then scrambled as defined by the TP-PMD Stream Cipher function to flatten the power spectrum energy such that EMI effects are significantly reduced.The scrambled seed is based on PHY addresses and is unique for each port. After scrambling, the bit stream is driven into the network media in the form of MLT-3 signaling. The MLT-3 multi-level signaling technology moves the power spectrum energy from high frequency to low frequency, which further reduces EMI emissions.7.2.6.100Base-TX Receive FunctionThe receive path includes a receiver composed of an adaptive equalizer and DC restoration circuits (to compensate for an incoming distorted MLT-3 signal), an MLT-3 to NRZI and NRZI to NRZ converter to convert analog signals to digital bit-stream, and a PLL circuit to clock data bits with minimum bit error rate. A De-scrambler, 5B/4B decoder, and serial-to-parallel conversion circuits are followed by the PLL circuit. Finally, the converted parallel data is fed into the MAC.7.2.7.Power-Down ModeThe RTL8305NB implements power-down mode on a per-port basis. Setting MII Reg.0.11 forces the corresponding port of the RTL8305NB to enter power-down mode. This disables all transmit/receive functions, except SMI (Serial Management Interface: MDC/MDIO, also known as MII Management Interface).7.2.8.Crossover Detection and Auto CorrectionDuring the link setup phase, the RTL8305NB checks whether it receives active signals on every port in order to determine if a connection can be established. In cases where the receiver data pin pair is connected to the transmitter data pin pair of the peer device and vice versa, the RTL8305NB automatically changes its configuration and swaps receiver/transmitter data pins as required. If a port is connected to a PC or NIC with MDI-X interface with a crossover cable, the RTL8305NB will reconfigure the port to ensure proper connection. This replaces the DIP switch commonly used for reconfiguring a port on a hub or switch.Note: IEEE 802.3 compliant forced mode 100M ports with Autoxover have link problems with NWay (Auto-Negotiation) ports. It is recommended to not use Autoxover for forced 100M.7.2.9.Polarity Detection and CorrectionFor better noise immunity and lower interference to ambient devices, the Ethernet electrical signal on a twisted-pair cable is transmitted in differential form. That is, the signal is transmitted on two wires in each direction with inverse polarities (+/-). If wiring on the connector is faulty, or a faulty transformer is used, the two inputs to a transceiver may carry signals with opposite but incorrect polarities. As a direct consequence, the transceiver will not work properly.When the RTL8305NB operates in 10Base-T mode, it automatically reverses the polarity of its two receiver input pins if it detects that the polarities of the incoming signals on the pins is incorrect. However, this feature is unnecessary when the RTL8305NB is operating in 100Base-TX mode.Single-Chip 5-Port 10/100Mbps Ethernet Switch Controller 13Track ID: JATR-3375-16 Rev. 1.0Single-Chip 5-Port 10/100Mbps Ethernet Switch Controller 14 Track ID: JATR-3375-16 Rev. 1.0 7.3. General Function Overview7.3.1. Power-On SequenceTwo power voltage types are required for RTL8305NB normal operation, 3.3V and 1.0V. The 1.0V is converted from 3.3V via the LDO of the RTL8305NB.• Ta is the moment when 3.3V power is higher than 2.6V (±5%). 3.3V power never falls lower than2.6V (±5%) after Ta• Tb is the moment when 1.0V power is higher than 0.71V (±10%). 1.0V power never falls lower than 0.71V (±10%) after Tb • Tc is the moment when both 3.3V and 1.0V power are stable (the voltage is always in the legal operating range) • Td is the moment that the pin reset signal is de-asserted •Te is the moment that the RTL8305NB device is ready to be accessed by an external CPUFigure 4. Power-On SequenceThe requirements are:• The time of Ta should be between 1ms and 20ms• The sequence of Ta is always less than Tb for the LDO of the RTL8305NB. In principle, the sequence of Td and Ta/Tb/Tc is also not required. The sequence of Td > Tc + 10ms is recommended• The time from Te to the later of Ta/Tb/Td is the sum of the time of the EEPROM loading + 30ms. The EEPROM loading time varies according to the autoloaded data bytes in the serial EEPROM• Reset。

Para minimizar el riesgo de lesiones, le rogamos que tome algunas medidas básicas de seguridad siempre que usted utilice este dispositivo. Por favor, lea detenidamente y al completo este manual de instrucciones y asegúrese de haberlo entendido.Guarde bien este manual de instrucciones.IndicacionesPonga el dispositivo cargador en “OFF” (apagado) antes de conectar el cable de conexión a la batería para evitar chispas peligrosas.Antes de quitar las pinzas de la batería, apague el dispositivo.Durante el proceso de carga pueden formarse gases explosivos, por ello evite el fuego, las chispas, etc.La pinza roja de la batería se conecta con el polo positivo y la pinza negra con el polo negati-vo. ¡NUNCA las intercambie!No utilice NUNCA el dispositivo cargador si los cables de carga o los bornes de la batería es-tuvieran dañados. Durante la carga, no lo golpee ni lo sacuda.No intente NUNCA cargar una batería congelada.Utilice los fusibles que se incluyen en el envío. NUNCA instale fusibles mayores.Limpie cuidadosamente la batería antes de la carga y compruebe su voltaje.Tenga en cuenta que la batería conectada debe tener mín. 50 Ah y máx. 750 Ah (Boos-ter 430) ó 800 Ah (Booster 630).Manejo seguro de las baterías•¡Utilice siempre gafas de seguridad y guantes de protección al manejar la batería! El contacto de la piel, los ojos o la ropa con el ácido de la batería debe ser evitado en todo caso, ya que el ácido es altamente corrosivo. Si el ácido de la batería entrara en contacto con los ojos, es-tos deben ser enjuagados inmediatamente con abundante agua, a continuación, póngase en contacto con un médico. Las salpicaduras de ácido en la piel deben ser eliminadas al momen-to con agua y jabón. Las salpicaduras de ácido en la ropa producen agujeros.•No coloque su cargador de baterías sobre materiales inflamables durante el proceso de car-ga. Durante su funcionamiento, el dispositivo se calienta. Coloque el cargador de manera que pueda ventilar adecuadamente. ¡Nunca cubra las ranuras de ventilación! El dispositivo de car-ga solo puede ser utilizado en espacios interiores. Proteja el dispositivo de humedad y humo.Si el dispositivo se mojara, existe el riesgo de sufrir una descarga eléctrica con peligro de muerte. Al cargar la batería, se liberan pequeñas cantidades de gas del ácido que esta contie-ne. Esto es normal. El gas de la batería se nota por la formación de burbujas. Tenga cuidado con las burbujas de gas que estallan, ya que causan salpicaduras de ácido alrededor. Para conectar la unidad es imprescindible seguir las recomendaciones, de lo contrario se podrían producir chispas que causen que los gases exploten (¡gas de oxígeno!). Del mismo modo, el dispositivo cargador no debe funcionar en las proximidades de llamas vivas. ¡No fume mien-tras manipule la batería! Asegure una buena ventilación, ya que el gas que la batería contiene es explosivo.•Preste atención: Cargue solamente baterías convencionales de plomo-ácido de 12 o 24 V.No cargue baterías no recargables. Cargue solo baterías intactas. El tiempo de carga depen-de del nivel de carga de la batería. Esto puede determinarse midiendo la densidad del ácido con un densímetro o areómetro, disponible en el mercado. Si tiene una batería permanente-mente cerrada y libre de mantenimiento, esta no debe ser abierta. En este caso, no es posible o necesario comprobar o corregir el nivel de ácido. Para cargar la batería, siempre que sea posible, deben quitarse en primer lugar todas las tapas de las células, como muestra la ilus-tración. Entonces, se debe comprobar el nivel de ácido en las células de la batería. Cuando la batería se descarga, el nivel de ácido debería estar todavía, aproximadamente, 0,5–1 cm por encima de las placas de plomo de las células de la batería. Si no fuera así, rellene con aguadestilada. Bajo ninguna circunstancia utilice agua del grifo. El nivel del ácido aumenta a medi-da que el estado de carga aumenta. Para evitar que con ello se desborde la batería, el ácido no debe rellenarse al comienzo del proceso de carga hasta la marca máxima. Los tapones de cierre solo pueden ser sustituidos una vez que el proceso de carga haya finalizado. Solo asíse permite que los gases que se hayan formado durante la carga escapen. El escape de pe-queñas cantidades de ácido a través de salpicaduras durante el proceso de carga es inevita-ble.Principio de funcionamientoCuando la batería se carga, la corriente de carga depende del tipo de batería. En general, la corriente de carga se sitúa alrededor de un 10 % por encima de la corriente máxima de la batería.Tiempo de cargaEl tiempo de carga depende de la batería. Una regla general es:tiempo de carga = capacidad de la batería ÷ corriente de cargaDurante el proceso de carga la corriente de carga irá disminuyendo cada vez más, de modo que el tiempo de carga calculado será como mínimo ¼ más largo. El cargador de baterías puede cargar una o más baterías al mismo tiempo. En este último caso, se sobrentiende que el tiempo de carga serámás largo.Si desea arrancar un vehículo con el Booster tenga en cuenta lo siguiente:1.Si se trata de un motor grande, es mejor realizar una carga rápida previa de 15 min antes dellevar a cabo un intento de arranque.2.En caso de que el motor que desee arrancar se trate de un motor diesel, deje que las bujíasde encendido se precalienten antes de intentar arrancar el motor.Para cargar, conecte la pinza roja de la batería al polo positivo y la pinza negra al polo negativo. ¡No las intercambie!Conecte los cables de conexión del dispositivo cargador a la batería. Conecte el cable rojo (+) con el polo positivo de la batería (+) y el cable negro (–) con el polo negativo de la batería (–). Si la batería todavía se encuentra en el vehículo, conecte el cable negro (–) al bloque del motor para que sirva de toma a tierra.

TP8305B 高效率恒流限流 WLED 驱动器说明书

南京拓品微电子有限公司DATASHEETTP8305B 高效率恒流/限流WLED驱动器TP8305B 高效率恒流限流WLED驱动产品简介TP8305B是一种输入电压范围宽（0.8~5.5V），可调恒定电流和限定电流两种模式来驱动白光LED而设计的升压型DC/DC变换器。

采用变频模式，逐周期限流，使输入输出电流随电源电压降低均匀变化。

该器件能利用单节或双节干电池驱动单颗大功率白光LED，同样可以利用一节锂电池驱动两颗、三颗或多颗WLED。

驱动WLED串联连接的方法可以提供相等的WLED电流，从而获得均匀的亮度。

46mV的低反馈电压最大限度地降低了电流调节电阻器的功耗，从而提高了效率。

46mV的限流反馈电压，可根据不同需求来设置限流值。

TP8305B与TP8305区别于在限流模式时，随着输入电压的降低，TP8305输入输出电流在某个点会突变，TP8305B采用了变频模式避免了这个现象。

其他功能均不变。

松下BQ830问题充电器的分析及有效改造（原创）

松下BQ830问题充电器的分析及有效改造（原创）松下BQ-830充电器完美改造方案的探讨看到网上关于松下BQ-830充电器的介绍很感兴趣，正好到上海虬江路二手货市场15元买了一个，用了三天测绘，三天检测、查资料，基本弄清了BQ-830的原理。

厂家声称的“国际标准的充电电路：负电压差微电脑控制及温度过热保护”纯属商业炒作，如此花样繁多，吸引眼球的直观功能，与美国那些质朴的智能充电器相比一定吸引了大量美国顾客，因此我们才看到如此之多的东洋垃圾。

松下BQ-830充电器的改造首先要遵从安全与简单实用的原则，安全第一，毕竟我们的电池每节都比BQ-830充电器的现价要贵，方法不简单普通人改造不了。

松下BQ-830充电器的改造有现实的意义，因为现在的电池容量已经在3600mA之上了，我们都迫切需要一个跟上时代步伐的大电流的快速充电器。

用市售几十元的充电器不但充电时间长，而且电池长期在C/10（容量的1/10）以下电流充电会产生枝晶效应，促使电池内部短路，因此电池厂家推荐在2-3小时充满电。

市场上现在一—至三百元的快速充电器充电电流在200-400mA左右，同样难满足要求，而且没有一个是微电脑智能控制。

很多厂家公开说假话早已经达到无耻的地步，中外如此。

毕竟精明的商人和高级骗子并无一步之遥。

能四槽独立充电控制的单片机智能充电器只在资料上看到过，市场上没有，估计太贵了。

真正的单片机智能充电器是根据什么来决定最完美的充电方法呢，了解了下列知识对于我们使用改造后的BQ-830充电器时，如何保护电池是相当重要的。

单片机智能充电器检测的项目，及充电方案：1. Vmin 及Vmax：镍铬(NiCd)电池放电终止电压，8小时放电率时为1.1V，1小时放电率为0.5V；镍氢(NiMH)电池一般认为是1V。

如果电池电压低于最低电压阈值（1V左右）则不能快速充电。

而是采用涓流充电进行修复，如果在规定时间仍达不到要求，则认定电池损坏，报警拒充。

A block diagram showing an example hardware installation before and after installation is shown below for reference.Figure 1: Example of Hardware Changes Associated with Replacing an MTL830B System with an MTL830C System(RTD, TC, or mV)(RTD, TC, or mV)(RTD, TC, or mV)(RTD, TC, or mV)2 Steps for replacing the MTL830B with the MTL830C system1. Record the settings if the exsiting MTL830B system.a. Record the channel configuration (thermocouple, mV, 2-wire RTD, 3-wire RTD or 4-wire RTD).b. Record the address of each MTL831B. The address is set by the positions of SW 100 switches1 and 2. NOTE: Only addresses 1 and2 are used.2. Power of the MTL830B system. This can be done by turning off or disconnecting the power to theMTL838B-HON units.3. Replace each MTL831B with an MTL831C (see the MTL831C Analog Transmitter Instruction Manual(INM MTL831C) for details).a. For hazardous area installations, confirm the Intrinsic Safety entity parameters of the sensorsare compatible with the entity parameters of the MTL831C.b. Move the wires from each MTL831B sensor input channel to the corresponding MTL831Csensor input channel.c. Each sensor input channel has 4 terminals labelled A, B, C, and D. The proper connections tothe terminals for each input type are shown in the drawing below.Figure 2: MTL 831C Terminal Connections for the Various Sensor Typesd. The extra components, terminal strips and wiring used to connect RTDs to the MTL831B arenot necessary on the MTL831C. The MTL831C supports direct connection 0f 2, 3 and 4-wireRTDs. Extra diodes for RTD measurements are not required with the MTL831C. Connect eachRTD to its own input channel port.e. Move the Data Highway cable from the MTL831B to the MTL831C. If two Data Highway cableswere used with the MTL830B system, select one of the two cables to use with the MTL830Csystem. The second Data Highway cable is not connected.f. On the MTL831C replacing the MTL831B with address 2 (if there is one), install a jumper wirebetween the ADDRESS terminals A and S (terminal numbers 7 and 8)Figure 3: Jumper Wire Between Address Terminals4. If an MTL3052 Isolator is installed in the Data Highway cable, replace the MTL3052 Isolator with theMTL5553 Isolator/Power Supplya. Shielded twisted pair Data Highway cable is highly recommended for noise immunity.b. The Isolator splits the Data Highway cable into 2 isolated sections. The shield of each section ofthe Data Highway cable must be grounded in only one location.i. Connect the shield of the section between the MTL5553 and the MTL831C to a cleaninstrument ground near the MTL5553.ii. The shield of the section between the MTL5553 and the MTL838C is grounded through the MTL838C when connections to the MTL838C are made as described below.iii. See Figure 1.c. Verify the load capacitance and inductance associated with your installation are compatible withthe MTL5553 intrinsic safety entity parameters.d. See the MTL5500 Series Instruction Manual (INM MTL5500) for details.5. Replace the MTL838B-HON with the MTL838C (see the MTL838C Receiver Instruction Manual (INMMTL838C) for details).a. Move the wires from the MTL838B-HON RS-485 ports to the corresponding terminals of theMTL838C.b. Move the wires from the MTL838B-HON Data Highway port to the corresponding terminalsof the MTL838C. If two Data Highway cables were used with the MTL830B system, connectthe same cable attached to the MTL831C Data Highway port(s) to the MTL838C Data Highwayport. The second Data Highway cable is not connected.c. Move the wires from the MTL838B-HON power port to the corresponding terminals of theMTL838C.d. A Shielded twisted pair Data Highway cable is highly recommended for noise immunity.Connect the shield to the MTL838C Data Highway connector S terminal.e. Connect one or both MTL838C GROUND terminals to a clean instrument ground.6. Apply DC power to the MTL830C system (turn on power to the MTL838C and MTL5553, if installed).7. Verify the MTL838C green POWER LED turns on.8. Verify the MTL838C green COMM LED is flashing. This indicates communication is established with theMTL831C(s). If not, verify proper connection of the Data Highway wiring.9. Install the MTL83xC Configurator software on a computer.10. Connect the computer to the MTL838C USB-C port.11. Use the software to configure the MTL838C to match the old MTL830B system settings you recorded(see the MTL83xC LLMUX Emulation manual (INM MTL83xC LLMUX) for details). On the MTL838C tab:a. Check for relevant firmware updates for the MTL831/MTL838Cb. Select LLMux as the Communication Protocol.c. Select the MTL831C transmitters that are connected (#1, #2, or both).d. Select the type of inputs connected to each MTL831C (mV/TC or RTD).e. Select the Line Frequency to 60Hz or 50Hz (frequency of power on site).f. Click the Download -> MTL838C button.Figure 4: Example MTL838C Configuration12. Use the software to configure the MTL831C(s) to match the old MTL830B system settings yourecorded.a. NOTE: The Honeywell system sends most of the channel configuration to the MTL830Csystem. However, the number of wires used for RTDs is not included in the configuration datasent by the Honeywell system. The default channel configuration for RTDs is 3-wire. If mV,thermocouple, and 3-wire RTD are the only channel configurations used then no MTL831Cconfiguration is required. If any channels are connected to 2- or 4-wire RTDs, set thosechannels using the software as described below.b. On each MTL831C tab where MTL831C is configured to measure RTDs, select the correctnumber of wires for the RTD for each channel. NOTE: this is only required for channelsconnected to 2- or 4-wire RTDs. Any channels connected to RTDs and left as “Not Configured”will be treated as 3-wire RTD when the Honeywell system enables them.c. Click the Download -> MTL831C button.d. NOTE: The MTL838C remembers the last way a channel was configured for RTD even if it islater unconfigured. if the Honeywell system then configures the channel for RTD, it will usethe number of wires that was last configured by the software. If you see unexpected behaviorwith RTDs use the software to configure the number of wires on ALL RTD channels so that you know they are correctly configured.Figure 5: Example MTL831C RTD Configuration13. Disconnect the computer from the MTL838C. NOTE: The Honeywell system will not be able to com-municate with the MTL830C system while the computer is connected to the MTL838C.14. Confirm the new system is operating properly using the Honeywell system.EUROPE (EMEA): +44 (0)1582 723633 ********************THE AMERICAS: +1 800 835 7075*********************ASIA-PACIFIC: +65 6 645 9888***********************The given data is only intended as a productdescription and should not be regarded as a legal warranty of properties or guarantee.
