Connect the FP-1001 to a host computer, or to the RS-485 repeater
port of an FP-1000, using the 5 position Combicon screw terminal
adapter of the RS-485 connector on the FP-1001. You may connect
up to 25 FP-1001 network modules to a single RS-485 port of a
host computer, or up to 24 FP-1001 network modules to the
RS-485 repeater port of an FP-1000. The pinout of the RS-485
connector is shown in Figure4.
Figure 4. RS-485 Connector Pinout
The TX+ of the host port (or FP-1000 RS-485 repeater port) must
be connected to the RX+ of all of the FP-1001 modules, and the
TX- of the host port (or FP-1000 RS-485 repeater port) must be
connected to the RX- of all of the FP-1001 modules. This pair of
connections provides communication from the host computer to
the FP-1001 modules.
