The VB552 VGA over Cat 5 repeater + audio is an audio/video signal extension device which is compatible with ATEN Cat 5 audio/video splitters. The VB552 extends the audio/video transmission range an extra 150m over Cat 5e (or higher) cables. The use of an additional repeater means the audio/video signals can be transmitted over even longer distances, up to 450m. The VB552 has adjustable video gain and compensation controls to provide the sharpest video quality possible. An IR remote control also provides picture control at the remote site. Rack-mountable, with two RS-232 channels on the unit for selection, and support for high video resolutions, the VB552 is the perfect solution to extend the range of your A/V and serial transmissions in any installation environment requiring VESA FDMI mount standards.
