## Description

Convert your existing straight wired cables to null modem or reverser (transmit & receive) cables with these handy, inexpensive adapters. Simply plug these adapters onto the end of a cable and you're done !

Review: Works to convert between crossover and straight through - Because serial is not exactly current technology it can be difficult to tell both what type of cable you need and what type of cable you are buying. Sellers don't know the difference and even if things are properly labeled the terminology and jargon might as well be hieroglyphics at this point. After purchasing the wrong ones, and buying the "right ones" but receiving completely different mislabeled cables, this item allowed me to get my DB9 - DB25 Epson Thermal Printers working. I still don't know exactly which cables I purchased or which I needed, but these fixed the issue regardless.
Review: Exactly as stated - These adapters were solidly built and worked as advertised. Fast delivery and excellent packaging.

These adapters were solidly built and worked as advertised. Fast delivery and excellent packaging.

### ⭐⭐⭐⭐⭐ Compact and secure null modem adapter with solid mechanical design
*by R***O on February 17, 2026*

I purchased these for connecting legacy equipment that requires a null modem configuration, and they worked exactly as expected. The slimline form factor is helpful in tight setups where multiple DB9 connectors sit close together. Fit is solid once connected, and there’s no noticeable play in the connection. One detail I especially appreciate is the mechanical design of the screw posts. Each jack screw is essentially a double-sided threaded post — one end secures the adapter to the equipment’s serial port, and the other end has internal threading to accept the thumbscrews from the connected cable or another adapter. This allows the connection to be mechanically fastened on both sides, which adds stability and prevents accidental loosening in lab, rack, or field environments. Signal transfer has been stable with no communication issues during use. For serial troubleshooting or legacy device connections, they’ve been reliable.
