RS232
Up-link
communication
port
It is adopting RS-232 series port to upload data. Contents of data
transmit include BMS parameters, battery running status, alarms, etc.
Generally, speed rate of RS-232 is 1200bps. RS232 up-link
communication can be available for the battery module with a binary
communication address of 0000 (Master PACK). Protocol for RS232
communication is shown in
Annexed Table 3.1

RS485
Cascading
communication
port
It is adopting RS485 series port communication pattern to upload data.
Communication of modules connected in parallel (Slave PACKs) is
available through RS 485. Data of slave PACKs will be transmitted to
Master PACK. Protocol for RS232 communication is
shown in
Annexed Table 3.2
