The RS485 BUS connection
There is a round four-pin socket located on the back plane of the device.
This is used for remote RS485 BUS control of the device.
Connect the RS485-BUS by the following scheme:
OUTPUT
INPUT
BUS-output
BUS-input
(„female“ socket)
(„male” socket)
The INPUT socket is used to connect the incoming BUS signal coming
from a BUS converter or a RS485 BUS interface.
The OUTPUT socket is used to connect the BUS terminator, if no
successive BUS device is looped into the RS485 BUS line.
