Allen Bradley 1203-GD2 Communication Modules

The 1203-GD2 Serial Communications Module is an interface device designed to deliver a digital link between serial communications devices and all devices that use SCANport technology. It is available in both open and enclosed configurations and is compatible with the following Allen-Bradley devices: 1336 PLUS, 1336 FORCE, 1305 MicroDrive, SMC, and SMP. It is intended for use with devices that communicate via RS232, RS422, or RS485 hardware standards (using the DF1 protocol), and the module contains three DIP switches as follows: SW1, SW2, and SW3. Switches have the option of being set to either ON or OFF. The communications module can be set up with three mounting configurations, as follows: open style board factory installed in a drive, open style board as a separate kit, or enclosed style for panel mount or DIN rail mount.
