There are a few options for establishing communication to configure the settings for the first time. For initial configuration prior establishing a LAN connection, a CAT 5 crossover cable can be used to connect directly to a PC. In this scenario, the controller has a static IP address and the web browser-enabled PC is connected directly to the controller using a crossover cable.Ports 2 and 3 utilize 2-wire RS-485 interface only. The interface allows multi-drop communication on a single bus of up to 4000 feet (1,200 m). Use twisted pair (minimum 24 AWG) with shield for the communication with 120 ohm impedance. Install termination jumpers only at the end of line unit.166 — revision 6Hardware Installation GuideWiring ports 2 and 3TR2+ TR2-TR2+ TR2-GNDTR3+ TR3- GNDGND TR3+ TR3- GNDPORT 2 2-WIRE RS-485Earth GroundPORT 3 2-WIRE RS-485Earth GroundWire with 24 AWG, stranded33.2Power and Alarm Inputs
