2.2.2 Network to FX-2200

Network wiring for communications to the FX-2200 is
connected to the terminal pairs marked C1+/C1- and C2+/
C2- (see Figure 1).
COM1 (C1+/C1-) is connected to COM2 the next panel in the
network loop. Ensure that the Annunciator is programmed to
communicate with the next panel or that COM1 is disabled as
required in the downloaded database. COM2 (C2+/C2-) is
connected to the previous panel in the network loop.

2.2.3 Operator Keys

All operator keys are wired between an X and a Y terminal. A
key switch may be placed in series with the Y2 terminal to
make certain operator keys limited access (see Figure 2).
The figure is typical only; any, all or none of the operator keys
can have the key switch used.

ports must be connected even if there is only one other unit in the system.
If the annunciator is programmed for single port operation, only COM2 (C2+/C2)
is connected.
COM1 and COM2 are power-limited and supervised.
For information on connecting a fiber optic network, please refer to the Fiber
Optic Module's Installation Manual.
