## 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.

## Features

- Converts standard, straight wired cables to null modem wiring
- Null modem configuration with pin 9 open
