Serial null-modem cable for DB9 devices

This 2-metre StarTech SCNM9FF2MBK cable links two DB9 female ports so that serial equipment can communicate directly without a separate modem. It suits technicians, industrial engineers and hobbyists who need a straightforward RS-232 cross-wired connection between legacy hardware or test gear.

Shielded construction resists EMI during extended

High-quality shielding protects the signal from electromagnetic interference, keeping data integrity stable over long transfers or continuous monitoring tasks. Molded connectors with built-in strain relief prevent cable fatigue where the wire meets the plug, so repeated mating cycles do not degrade performance.

Fixed two-metre length

The black PVC jacket measures exactly two metres, limiting placement flexibility but eliminating excess slack in tight racks or control panels. Both ends are DB9 female, so the cable only fits equipment presenting male RS-232 ports; installations that require male-to-female or male-to-male wiring will need a different assembly.

Questions about this item

Does the 2 m length of this DB9 null-modem cable add noticeable resistance or signal loss when it runs all day?

The 2-metre DB9 null-modem cable uses high-quality shielding and moulded connectors with strain relief to maintain reliable RS232 connections free of EMI interference during continuous use.

What serial ports must my two devices already have to plug this cable in directly?

Both devices need a standard DB9 female RS232 port; the cable provides a DB9 female connector on each end for a direct null-modem link.

Will this null-modem cable work with legacy 9-pin serial equipment I still use?

Yes, the DB9 female-to-female pin-out follows the RS232 null-modem standard, so it connects older 9-pin serial devices without adapters.
