17 APPENDIX C: COMMUNICATOR / CONTROLLER
CONNECTIVITY
When designing a control system:
•
Rotem Communicator supports multiple infrastructure technologies: RS-232 and RS-485.
•
Each Rotem Controller has its own specific communication card for any supported
communication infrastructure.
•
There is specific wiring required for each infrastructure.
This paper details which 1) controller communication cards to install 2) wiring infrastructure to use in
order to support each infrastructure technology.

Wiring
3-wire shielded cable
2-wire shielded cable; must be
twisted pair preferred
4-wire shielded cable;
must be twisted pair
Examples
:
•
To connect a Platinum Controller over RS-232 cable, order a Platinum controller equipped with
a 232 ISO / 232 Extension Card or a 232 ISO/ 485 Extension Card. Use 3-wire shielded cable.
•
SuperGuard only supports RS-485 cable. Therefore, order a SGP 485 Communication Card
and use 2-wire shielded cable (twisted pair).
