Allen-Bradley 1747-CP3 SLC 500 Programmer Cable, 3-meter (10 ft) serial communication cable, Dual 9-pin D-shell female DTE connectors

Establish direct hardware-level serial connectivity with the Allen-Bradley 1747-CP3 SLC 500 Programmer Cable. Purpose-built by Rockwell Automation for classic industrial networking setups, this shielded 3-meter (10 feet) cable links your central programming station or HMI device to the integrated RS-232 Channel 0 port of legacy SLC 5/03, 5/04, and 5/05 processors. The cable also connects processors to an Advanced Interface Converter (AIC+) module to distribute signal transmission across wider network clusters. 

The physical configuration consists of a space-saving 90-degree right-angle female DB9 connector designed to snap tightly under closed enclosure doors, combined with a straight female DB9 connector for host interface mapping. The internal wiring contains a hardware-jumpered null-modem pin configuration with crossed RxD/TxD paths and RTS/CTS handshake loops. This design facilitates highly stable serial data exchange at speeds up to 19.2K baud without dropping critical status packets. Enclosed in a heavy-duty, over-molded PVC jacket with full outer screen shielding to block electromagnetic transients, this original accessories wire is the standard tool to execute firmware configurations, system data backups, and direct RSLogix 500 ladder monitoring on classic manufacturing floors.
