Q-4300 chassis allows users to locate DVI and SDI monitors (via fiber) from just a few meters up to 40km away from the controlling computer, securely and without the loss of resolution. The Q-4300 is a rack space saving, high reliability solution providing a rack mount for up to 4 modules of DVI and/or SDI, dual USB HID and audio in a compact 1U chassis. Ready for the challenges of demanding applications, the Q-4300 can combine any variety of DVI and SDI modules, along with USB HID and audio in trasmit/receive units for a space saving and cost effective solution. Four functional source computers each connected to a Q-4300 chassis equipped with four Velocitydvi module 3 transmitter interface components, which extends dvi video signals to one Q-4300 receiver chassis equipped with four Velocitydvi module 3 receiver interface components. Signals are routed through the Thinklogical VX 320 router. Three sources each connected to a Q-4300 chassis transmitter which extends DVI and SDI video, audio and serial signals to three destinations at separate workstation locations. Thinklogical receiver components used one Velocitydvi 3 receiver, one Velocitydvi-6 A/V+ receiver, and one SDI Xtreme 3G+ receiver.
