10.6.1 Configuration of a FC700 series
panel RBus interface
The routing of the RBus is controlled by the DIP
switches XP4 1A/1B, 2A/2B, 3A/3B. The switches are in
pairs as the A and B lines of the RBus are switched sep-
arately.
The combination of these switches controls the routing
of the RBus to the front door GUI or external devices.
The front door GUI communicates with the panel over
Ethernet, but may be configured to use RBus in Standby
Emergency Mode should there be a failure of the main
panel CPU.
The GUI and panel both have built in terminating resis-
tors, so external terminating resistors should not be fit-
ted to the panel. The table below shows all the switch
combinations.
The recommended configurations, depending on what
devices are connected to the RBus, are highlighted in
grey in Table 4.
Refer to Figure 21 to see the electrical layout of the
switches.
XP4 1A/1B XP4 2A/2B XP4 3A/3B Configuration
OFF OFF OFF No RBus.
OFF OFF ON RBus only to internal GUI.
OFF ON OFF RBus only to external devices.
OFF ON ON RBus routed to internal GUI and external devices.
RBus will have double termination resistors at
panel end.
ON OFF OFF No Rbus.
ON OFF ON RBus routed to external devices through internal
GUI.
ON ON OFF RBus routed to internal GUI and external
devices.RBus will have double termination resis-
tors at panel end.
ON ON ON Invalid configuration. This will result in RBus errors.
