VP-81N 8x1 VGA/XGA/Audio Switcher 

The Kramer VP-81N/VP-161/VP-321 are 8x1/16x1/32x1 switchers for VGA/XGA and balanced stereo audio signals. They are designed to route one of up to 8/16/32 inputs using 15pin HD female connectors for the VGA/XGA signals, and detachable terminal block connectors for the audio. Inputs and outputs are DC coupled, and up to seven units can be cascaded to efficiently increase the number of inputs. Bandwidth exceeding 400MHz ensures transparent VGA/XGA performance. There are many methods of switching the VP-81N/VP-161/VP-321 : they  can be controlled via their front-panel switches, an IR remote controller, and via remote contact closure switches.  In addition, RS-232/RS-485 serial control can be used, such as that transmitted by a touch screen system, PC or other serial control device. VGA/XGA and audio signals can be switched separately (in Breakaway mode) or together (in Audio-follow-Video mode), and the switchers are perfect matches for Kramer's VPM-2 wall mount units. The machines are housed in rugged, professional rack mountable enclosures.
