Connectivity for Legacy Serial Devices

This 6ft null modem cable links two serial devices that require a cross-wired connection. It carries a DB9 female connector on one end and a DB25 male connector on the other. Gold-plated contacts and foil shielding protect the signal against interference. The moulded construction is built for a long service life.

Ideal for Direct DTE-to-DTE Links

The cable suits installers connecting a PC serial port to a modem, plotter or industrial controller that expects a DB25 interface. It is not intended for straight-through peripheral extensions or for devices that need a DB9-to-DB9 pinout. Buyers who need a different gender combination or a longer run should select an alternative part.

DB9 Female to DB25 Male Pinout

The decisive specification is the connector pairing: one end is DB9 female, the other is DB25 male. This fixed pinout determines whether the cable matches the two ports you are joining. Verify the port genders on both pieces of equipment before ordering.

Questions about this item

Will the DB9 female end plug straight into the 9-pin serial port on my legacy PC?

Yes, the DB9 female connector mates directly with a standard 9-pin serial port so no adapter is needed for that side of the link.

How can I verify the cable is wired correctly once I connect both ends?

A successful serial handshake — such as a terminal session opening or a modem responding to AT commands — confirms the cross-wired pinout is functioning.

Does the package include any gender changers or extra connectors for other port types?

Only the 6ft cable with a DB9 female on one end and a DB25 male on the other is supplied; no additional adapters are included.
