3.9 RS 485 rear communication
This test should only be performed where the relay is to be accessed from a remote location
and will vary depending on the communication protocol being adopted (refer to label under
the upper flap).
It is not the intention of the test to verify the operation of the complete system from the relay
to the remote location, just the relay's rear communication port and any protocol converter
necessary.
Connect a laptop PC to the RS485 rear port (via a KITZ for Courier communication) and
check the communication with the appropriate command.
