OEM RS232 Cable Set
5.8.2.1
OEM RS232 CABLE SET
Insert the mixed D-Sub plug of the cable into the socket of the final module. The system should be
deactivated when you do this. Tighten both screws on the plug manually. You do not need a bus
termination plug, since the plug of the RS232 cable already contains a bus termination resistor.
Now, plug the 9-pin D-Sub socket of the cable into an RS232 connection on your PC or other controller.
For greater distances to the socket please use a 1:1 cable with a 9-pin D-Sub plug.
Now, you can reactivate your system and send or receive data through RS232. Since every module
contains a gateway from RS232 to the system’s internal CAN bus, you can now address each module of
your system with only one RS232 cable.
