3 The IC-2 Communication interface

The IC-2 appears as a small plastic box that contains the electronics. A green LED on the front panel is lighted when
the power is on.
The box can be opened exerting pulling the upper side from the lower side; there are no blocking screws.

Fig. 3.1

Inside, the printed circuit board is marked CD95204/B; the only features relevant to the installer are the connector's
block and the jumpers (see Fig. 3.2).
The following connections are provided:

−

RS485 communication line (towards CMX,Westinghouse 422)

−

IC-2 power supply

−

RS232 communication line (towards Gateway)

The jumpers let you set:

−

Baud rate: jumpers A, B, C, D, E, F - refer to Table 3.1.

The RS-232 communication line toward the gateway is a 3-wire connection.
