ZvPro 280 is configured via a USB cable to a PC running a software program called ZvConfig. You can get creative, setting channel names, customize idle screens with the customer's logos, and even change the 'heartbeat' watermark in the lower right corner with an image of your choosing. There is also a command line interface that can be used with either the RS-232 port or USB connection. See the ZvBox Configuration page to learn more.
