Figure 26. 10-Position Modular Jack Pin Locations
Figure 27 shows how to wire several FP-1001 banks in an RS-485 network
controlled by the cFP-2220/2220A. Only two FP-1001 banks are shown,
but the cFP-2220/2220A can control up to 24 FP-1001 banks. Install 120
Ω
termination resistors at each end of the network as shown in Figure 27.
