    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.
