his RS-485 Junction Interface help simplify cable management of RS-485 networks by utilizing both screw terminals and RJ11 connectors. This RS-485 junction makes it easy to connect our USB to RS-485 converter (PR49-4) to CAT3/5 cabling. Users may use network cables or RJ11 connectors to interconnect junction modules. Please see the wiring diagram in the “Resources” tab for a complete wiring example. Requires minimum 4-Conductor RJ11 cable (not included).
Our RS-485 Serial Communications Module makes it easy to network up to 256 NCD devices together at distances up to 4,000 feet. Each RS-485 node includes 3 screw-terminals for a 3-wire connection to the RS-485 master.
