2.4 Communication Function
a) RS232 communication
RS232 Port use 6P6C vertical RJ11 Socket
RJ11 Pin| Define
Pin 1、 2、6| NC(empty)
Pin 3| TX(computer receives data)
Pin 4| RX(computer sends data)
Pin 5| GND(ground)
BMS can communicate with the upper computer through RS232 interface, so that it can monitor all kinds of battery information, including battery voltage, current and temperature, working status etc. The default baud rate is 9600bps.
b) RS485-1 / CAN main communication If you need to communicate with the
monitoring device through RS485 or Can, the monitoring device will be used as
the host, and the address setting range of other batteries will be 2~15
according to the polling data of the address.
The product adopts isolated communication design, supports RS485/CAN
communication mode, RS485 communication default baud rate is 9600 bps, 8 bit
data bit, 1 bit stop bit, no test bit; The default baud rate of CAN
communication is 500Kbps；
RS485 & CAN use 8P8C vertical RJ45 socket
RS485 PIN| Define| CAN PIN| Define
1、8| RS485-B1| 9、10、11、14、16| NC
2、7| RS485-A1| 12| CANL
3、6| GND| 13| CANH
4、5| NC| 15| GND
c) RS485-2 communication for parallel connection With dual RS485 interfaces, the default baud rate is 9600bps. If you need to communicate the batteries in parallel with the monitoring device or inverter, you need to connect each battery with RS485-2 ports, so the host battery can read the information of each battery.
RS485-A & RS485-B use 8P8C vertical RJ45 socket
RS485-A PIN| Define| RS485-B PIN| Define
1、8| RS485-B| 9、16| RS485-B
