Plugging and unplugging network cables
The display base module is provided with two RJ45 network
sockets.
The socket 1 in the first station is for the bus terminating
resistor. For other stations, socket 1 is used for plugging in
the incoming cable. Socket 2 is used for the outgoing cable
or for the bus termination resistor on the last physical station
in the network.
