Wiring Procedure of Communication Line
The system using LIBM
・
Connect CN1 (Receive) with CN2 (Transmit) of the modules and connect CN1 and
CN2 of the module with CN4 (Receive) and CN3 (Transmit) of LIBM to wire the
communication line in a loop.
・
Ensure that the LIBM external output signaling is used to control the system.
・
For operation of the LIBM, refer to the LIBM instruction manual.
2.3 Connector Input/Output Summary Table
Table 1 shows the connector input/output and the pin assignments of the battery module. CN1
is a receiver of module communication and CN2 is a transmitter of module communication.
