The both side of BMS to MBMS communication cable must be marked with labels.
The last port of Ethernet Switch is for the MBMS.
From the 1
port to the n
st
can fastest find out the corresponding battery string on the Ethernet Switch.
3.6.3 ADD Switch Setting (Address Assignment)
ADD Switch is a 6 bit dial switches to manually distribute the
communication address of the battery system. Nether position is OFF,
means "0". Upper position is ON, means "1". 1
address, and the 6
bit dial switch support a 120Ω resistance (Terminal
th
Resistance).
ADD Switch MBMS is a 6 bit dial switches to manually distribute the
communication address of the battery system. Nether position is OFF,
means "0". Upper position is ON, means "1". 1st bit to 4th bit is for
address, the 5th and the 6th bit dial switch support a 120Ω resistance
(Terminal Resistance).
3.6.3.1 Under communication for single BMS (battery string qty. 1 set)
The BMS's first five bits must set in below <BMS's Address Configure Table>. The last BMS's terminal
resistance must set in "1" (X=1);
The address is configured follow ASCII code: ("X" is terminal resistance).

3.6.3.2 Under CAN Communication Mode between MBMS and BMS (battery string qty. s6 set)
The BMS's first five bits must set in below <BMS's Address Configure
Table>. The last BMS's terminal resistance must set in "1" (X=1), and
other BMS's terminal resistance must set in "0".
The address is configured follow ASCII code: ("X" is terminal
resistance).
BMS's Address Configure Table:
The MBMS's ADD Switch set with "000011". The last 2 bits are terminal
