Summary
2 The FP-1001 has a simple rail clip for mounting reliably onto a standard 35 mm DIN rail. To install the FP-1001 to the DIN rail, follow these steps: 1. With a flat bladed screwdriver, open the DIN rail clip to the unlocked position as shown in Figure 1. Figure 1. DIN Rail Clip 2. Hook the lip on t...
3 Figure 3. Installed Network Module Network Connection 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-4...
4 The RX+ of the host port (or FP-1000 RS-485 repeater port) must be connected to the TX+ of all of the FP-1001 modules, and the RX- of the host port (or FP-1000 RS-485 repeater port) must be connected to the TX- of all of the FP-1001 modules. This pair of connections provides communication to the h...
