Overview

Specs

Reviews

This 6-pack DB9 male-to-male serial gender changer is a practical RS232 cable extender for all D-SUB 9-pin serial devices. It connects two female-ended serial cables to lengthen transmission lines without replacing full-length serial cables.

All internal pins adopt gold-plated shielding treatment to suppress external noise interference, effectively avoiding data loss, communication disconnection and device unrecognition during long-hour continuous industrial operation.

The lightweight tiny structure will not block equipment ports, and the sturdy wear-resistant plastic shell supports frequent plugging and unplugging. No complicated setup steps needed, direct plug-and-play use.

It is widely used in industrial automation equipment debugging, cash register connection, laboratory measuring instrument wiring, old server console port maintenance and vintage computer serial system renovation.
