The 1747-PIC SLC 500 RS-232 to RS-485 Interface Converter by Allen-Bradley is a device that allows RS-232 devices like the SLC 5/03, SLC 5/04, SLC 5/05, MicroLogix 1000, 1200, and the 1500 to connect to a DH-485 network. It has a 25-pin connector for interface pin-out, a 2-pin connector to transmit data from the PC to the converter, a 20-pin connector for a PC and a converter, and a 3-pin connector for receiving RDX Data from the converter to the PC. The 1747-PIC works best with the built-in COM1 and COM2 serial communication ports. It is not compatible with the USB-to-serial adapter and it does not support serial port extender boards which extend the COM port capacity.
