3 ft Null Modem Cable

This three-foot serial cable connects two DB-9 female ports with a null-modem crossover so RS-232 data flows directly between DTE devices. The CMG in-wall rating makes it suitable for permanent installation in educational or commercial buildings.

Low-Profile 1.25 in Connectors

Molded connectors measuring 1.25 inches total depth fit tight gang boxes and allow the cable to sit behind shallow monitor mounts. Full shielding blocks EMI and RFI interference while thumbscrews secure each end without tools.

Female-to-Female RS-232 Link

The crossed transmit and receive lines enable a direct link between two serial ports such as a PC and a legacy console or industrial controller. Buyers who need a male-to-female straight-through cable or a longer run will need a different assembly.

Questions about this item

What does the 232 in the RS-232 rating mean for everyday serial connections?

It identifies the electrical standard for point-to-point serial links, so this cable carries the correct voltage levels and signal timing for legacy COM ports and industrial equipment.

How does the DB9 female-to-female null-modem wiring affect the interface?

The transmit and receive lines are crossed inside the hood, letting two DTE devices such as PCs or PLCs talk directly without a separate adapter.

Will the 1.25 in low-profile connectors fit behind my rack-mounted patch panel?

Yes, the slim 1.25 in depth is designed for tight gang boxes and shallow monitor mounts, leaving enough clearance for the thumbscrews to tighten.
