10 ft DB9 Null Modem Cable

This 10 ft DB9 female-to-female null modem cable links two DTE devices directly through their serial ports without a DCE device in between. It is built for PC-to-PC data transfer or for connecting a PC to a nearby serial peripheral using modem protocol. The fully moulded connectors include thumbscrews for a secure, tool-free attachment. All materials comply with the RoHS directive.

Suits direct serial links.

The cable serves users who must join two DB9 serial ports for file transfer, legacy hardware communication or industrial equipment control. It will not work for parallel printer ports, USB connections or any interface other than DB9 serial. Buyers who need more length, a different connector gender or a non-null-modem pinout should look at another cable.

DB9 female-to-female crossover pinout

The single specification that decides fit is the DB9 female-to-female null-modem wiring, which crosses transmit and receive lines so two DTE devices can communicate directly. Verify that both endpoints present a DB9 male port and require a crossover cable before ordering.

Questions about this item

Which length should I choose for connecting two serial devices?

This cable is 10 ft long and coloured grey; pick it when the two DB9 ports are within that distance.

What does the null-modem wiring do inside my machine?

It crosses transmit and receive lines so two DTE devices such as PCs can talk directly without a modem between them.

What interface does the DB9 connector use and what does it limit?

The 9-pin DB9 female ends carry standard serial signals; throughput is set by the UARTs in the connected equipment, not by the cable.
