Product information

Description

The StarTech.com NM9FF Null Modem Adapter provides a simple, cost-effective way to convert a straight-through DB9 serial cable into a null modem connection. Featuring two DB9 female connectors, this compact adapter enables direct RS-232 communication between two serial devices without the need for an external modem. The NM9FF is designed for reliable point-to-point data transfer and is backed by StarTech.com's lifetime warranty and free lifetime technical support.

Advantages

The adapter uses two DB9 female connectors to invert transmit and receive signals for straightforward null modem operation, reducing the need to purchase special crossover cables. Its compact inline design preserves desk and rack space and requires no external power. Manufacturer support includes a lifetime warranty and complimentary technical assistance.

Suitable for

Connecting two RS-232 serial devices directly (PC-to-PC, router-to-console, industrial equipment)
Temporary or permanent serial data transfer and debugging
Field service, laboratory setups, and legacy system integration

Key specifications

Model: NM9FF
Connector type: 2 × DB9 female (DE-9F)
Interface: RS-232 (null modem)
Brand: StarTech.com
MPN: NM9FF
EAN: 0065030815789

How to use

Insert each end of the NM9FF adapter into the DB9 male connectors of the two serial cables you want to join. The adapter will swap the necessary transmit and receive lines so the connected devices can communicate directly via RS-232. No drivers or power source are required; the adapter functions passively as a wiring crossover.

Usage recommendations

Use short, well-shielded serial cables where possible to minimize signal degradation. Confirm DB9 pinouts of your devices if they use non-standard wiring. For critical or long-distance links consider using active line drivers or higher-grade cabling.
