Connecting the Concentrator to the Controller via RS-232 Connections
To connect the concentrator to the controller:
1.
Connect one end of the eight-wire communication cable to the Radio INT adaptor card, located in
the controller. Connect the wire’s other end to the Galcon Galcel (AI0617) connector.
2.
Connect the Galcel connector to the communication adaptor.
Figure 7: Galcel-to-Adaptor Connection
The communication adaptor is used to convert outgoing RS-232 signals from the Radio INT adaptor
card into RS-485 signals; this enables the transmission of the signals to the concentrator even at a
distance from the controller (up to 30 m).
3.
Connect the double-wire communication cable from the concentrator to the communication
adaptor:
Connect the brown wire to input
TX+
in the communication adaptor.
Connect the blue wire to input
TX-
in the communication adaptor.
