I've hooked up multiple gate systems with these and each one works flawlessly. Hard to mess these up, no complaints.

Perfect adaptor to customize DB9 pinouts without having to solder. Used by my technicians in our Fire Alarm company in NYC for all different types of Fire Alarm and Security Programming from laptop to Panel. A standard 4 wire RJ11 flat cable connects to one side, a USB to DB9 Male for the other side. Easiest configuration module option for this industry.

These adapters are used as part of an access system. It is easy to set the pins in the configuration we need.
