FC BUS Terminal Block
An FC bus connects to BACnet MS/TP, Modbus, or N2
devices. Third party BACnet MS/TP or Modbus devic-
es can also be connected to the FC bus. Units shipped
with a BACnet IP card cannot support BACnet MS/TP,
Modbus, or N2 on the FC bus. Unplug the BACnet IP
card to support other protocols.
The FC bus terminal block is a removable, 4-terminal plug
that fits into a board-mounted jack. Wire the removable
FC bus terminal block plugs on the main control board
and other control boards in a daisy chain configuration
using a 3-wire twisted, shielded cable as shown in Figure
40. See Table 27 on page 95 for more information.
