IP-485 is an open standard communication technology that allows users of existing twisted pair networks to expand and update existing serial data buses to simultaneously transport both Ethernet and RS-485, RS-422, RS-232, Modbus serial, or other serial data on the same twisted pair wiring without running Point-to-Point CAT5/6 wiring.
