Description
(e)
RJ-45 connectors for an external network on 2 wires RS-485
These connectors allow the Xcom-485i to be connected to a third party system (SCADA,
PLC, etc.) on RS-485.
Do not connect any devices suited for standard Ethernet connection.
(f)
Switch for RS-485 termination
This switch activates or deactivates the communication bus termination. The termination
is by default activated. In Figure 4, the termination is activated (T). Place the switch to the
correct side: if there is only one cable connected on port e put the switch in T (terminated)
position. If there are two cables connected on port e (Xcom-485i connected to two other
devices) place the switch in position O (open).
