Connect Serial Devices Over Long Distance

This cable extends an RS-232 link up to 500 feet (152.4 m) between a host and any serial peripheral such as printers or terminals. It is built for industrial or office installations where standard cable lengths fall short. The heavy-duty construction supports reliable data transmission across the full span.

Removable Metal Hoods Allow Repinning

Each end features metal EMI/RFI hoods that can be removed to repin the connector for custom wiring needs. This flexibility helps installers adapt the cable to non-standard pinouts without replacing the entire run. The shielding protects signal integrity in electrically noisy environments.
