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.
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.
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 host computer from the FP-1001 modules.
5 modules on different serial ports may have the same address. Every module on one serial port of a host computer must have the same baud rate. Figure 6.
6 Switches 6-8 set the baud rate of the FP-1001. Table 2 shows the switch positions and the corresponding network baud rates. 40 170 50 180 60 190 70 200 80 210 90 220 100 230 110 240 120 Other Settings Not Allowed Table 2.
7 Powering the FP-1001 NOTE: Terminal bases must be connected to the FP-1001, and the baud rate switch must be set, before power is applied to the FP-1001. An 11-30 VDC power supply is required by each FieldPoint stack. The network module filters and regulates this supplied power and provides power for all the I/O modules in the stack.
