The Unitech MS830 supports keyboard wedge interface for PS/2, AT, RS232, USB, & Wand. When used as a keyboard wedge, the operation of the keyboard remains unaffected. It uses a 3-in-1 interface which makes it easy to select and replace connection cables. Like other Unitech scanner products, MS830 setup is fast and easy. A bar code menu provides extensive setup options. A simpler quick setup menu lets users configure common features. Once ready, the configuration can be cloned and applied to other units through the use of custom bar code labels. This is very useful when deploying large installations.
