The StarTech.com NM9MF is a DB9 male-to-female null modem adapter that converts a straight-through cable into a null modem cable, for users connecting serial equipment that requires a null modem connection.
Recommended For
- IT technicians connecting two DB9 RS-232 devices that need a null-modem (crossover) connection can use this adapter to convert an existing straight-through 9-pin cable rather than replace the cable. Confirm the devices’ required pinout first.
- Network or server administrators troubleshooting a DB9 serial console can use it when the host and console device require crossed transmit and receive lines and they already have a compatible straight-through cable.
- PC, terminal, or legacy-device users making a direct serial connection between two DTE devices can use it to adapt an existing DB9 cable for a null-modem link, provided the devices’ connector genders and wiring requirements match.
- Homelab and repair users who keep a straight-through DB9 cable on hand can use this small adapter when serial-console troubleshooting shows that a null-modem connection is required.
