Either 2-wire or 4-wire RS-485 cable configuration can be used for series 1. Only 2-wire RS-485 cable configuration can be used for series 2. The main run RS-485 cable should be no longer than 4000 feet (1219 m), 100 ohms maximum (Belden 9842, West Penn, or equivalent). The drop cables (to readers and other devices) should be kept as short as possible, no longer than Ten (10) feet (Belden 9502 or equivalent).The RS-485 communication is asynchronous, half-duplex, using 1 start bit, 8 data bits, 1 stop bit.revision 6 — 259LNL-1100 Input Control Module
