The controller communicates to the host via the onboard 10-BaseT/100Base-TX Ethernet interface (port 0) or RS-232 interface (port 1). The RS-232 interface is for direct one to one connection to a host computer port or via modem, 50 feet maximum.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.The downstream communication port (TB3) is a 2-wire RS-485 interface which can be used to connect additional I/O panels. The interface allows multi-drop communication on a single bus of up to 4000 feet (1200 m). Use twisted pairs (minimum 24 AWG) with an overall shield for communication.Important:
