[Communication connector]
Connector for monitoring status data inside the power supply by communication. In order to
enable communication of multiple power sources by multi-drop, two connection ports are
provided. The differential signal of each connection port is short-circuited, so any port can be
used for connection. The cable side connector is an accessory.
Even if the communication connector is not connected, it does not affect the operation of the
power supply unit itself.
