Purpose-built null-modem link

This one-metre RS-232 cable carries a DB-9 female connector on each end, wired as a null modem so two DTE devices can communicate directly without a separate modem. The moulded strain relief protects the solder joints during repeated connection cycles. It is intended for technicians and hobbyists who need a ready-made crossover link for legacy serial equipment.

Suited for direct DTE-to-DTE ties.

The female-to-female, crossover pin-out serves administrators configuring routers, switches or industrial controllers through their console ports, and developers testing serial protocols on bench hardware. Builders who require a straight-through extension for a DTE-to-DCE connection, or who need male connectors to plug into standard PC ports, should select a different cable assembly.

Steady signalling over the full metre

Because the conductors are short and the crossover is hard-wired, signal integrity remains consistent during long configuration sessions or automated test runs that last hours. The moulded hoods resist cable fatigue at the connector junctions, so the link stays reliable even when the cable is routed through tight cable-management channels or moved between test stations.

Questions about this item

What serial port must my computer or device already have to plug this cable in?

You need a standard DB9 male RS-232 port on each device you want to connect, because both ends of this cable are DB9 female connectors.

Will this null-modem cable work with legacy RS-232 equipment such as an older modem or industrial controller?

Yes, it is wired as a straight RS-232 null modem, so it can link two DTE devices like a PC and a legacy modem or controller without a separate adapter.

How can I verify the link is active after connecting the cable?

Open a terminal program on both machines, set identical baud rate, data bits, parity and stop bits, then type on one side — characters should appear on the other if the cable is working.
