• NT21 Serial Port Adapter (RS232 to RS422)
• To convert either NT21 serial port to an RS422, connect this 2 or 4 wire connection adapter directly to the RS232 port. There are screw terminals for RS422 connections and the on-board switch allows you to choose between 2 wire or 4 wire and physical termination settings for the RS422 network. Using the NT Link 1: N protocol configuration, you can connect up to 8 NT21 touch screens to a single Omron PLC serial port via this adapter. The 4 wire connection cable has a Belden 9729 (part number; 802-373 802-373).
