USB under Multicast Mode

When connecting USB devices to the DVI KVM over IP, the functionality is similar to that of video and RS-232. There are two USB modes available in multicast mode: Active per request mode and Active on link mode.

For an example, we’ll begin with the last diagram and connect another keyboard and mouse device to Receiver R1. This will allow us to control the computer from two separate locations.
