3.1 Wiring of communication cable

LG Chem RESU batteries require a communication wire to the ISS 1Play.
The ISS 1Play will send the necessary keep-a-live command to the LG RESU battery, which is needed to
keep its internal circuit breaker close. When the battery does not receives for 10 minutes such a command, its
internal circuit breaker opens.
The ISS 1Play uses a three-pin CAN BAT connector and the LG RESU uses a RJ-45 connector. The pin-out
is the following:
