dinoo31 0 Posted February 7, 2017 Hi, I have an interface Wiegand / F/2F for managing a door acces which is Martec S973 (on the electronic card) and I don't have user manual of this equipment. This system was installed 7 years ago, it works properly but when I wanted to replace a broken one it doesn't work. I have only a small doc which says usb for hyperterminal configuration. It has a usb port but don't know how to configure it. If any information about this equipment don't hesitate. Share this post Link to post Share on other sites
