Serial null-modem cable for legacy links

This two-metre DB9 cable crosses transmit and receive lines so that two DTE devices can communicate without a modem. It carries standard RS-232 signals between equipment that still relies on nine-pin serial ports.

Sustained data transfer over the full length

The six-point-five-six-foot run maintains reliable RS-232 signalling for continuous file transfers or terminal sessions. Shielded construction reduces interference during extended use in industrial or laboratory environments.

Verify port gender and pinout before ordering

Ensure the host side presents a male DB9 connector and the peripheral side a female DB9, or use a gender changer if your ports differ. Confirm that both devices expect a null-modem crossover rather than a straight-through cable.

Questions about this item

Does the 2 m RS-232 null-modem cable generate any heat or noise during continuous all-day use?

No, the passive DB9 cable carries only low-voltage serial signals and has no active electronics, so it produces no heat and makes no noise.

What ports must my equipment already have to use this DB9 male-to-female serial cable?

One device needs a DB9 male RS-232 port and the other a DB9 female RS-232 port; the cable simply bridges those two connectors.

Will this 2 m null-modem cable work with legacy 9-pin serial gear I still own?

Yes, it follows the standard RS-232 pin-out, so any older DB9 serial device that expects a straight-through null-modem connection will communicate correctly.
