3Overview

The VP-81KSiroutes any input to both outputs, using 15-pin HD female connectors for the computer graphics video signals, a 3.5mm mini jack for the unbalanced stereo audio Output 1 signal, and a detachable terminal block connector for the balanced stereo audio Output 2 signal.

In particular, the VP-81KSi:

•Has a very high video bandwidth ensuring transparent WUXGA performance

•Features audio-follow-video (AFV) in which all operations relate to both the video and the audio channels, or audio breakaway option, in which video and audio channels are switched independently

•Features volume control

•Includes the Kramer innovative integrated sync processing Kr-isp™ technology, which lets you achieve a sharp, stable image even when the sync level is too low, by restoring the sync signal waveform

•Up to eight units can be cascaded to provide a single “virtual” switcher with up to 57 inputs

•Supports the SI-1VGARemote Step-in Panel for remote inputs and remote step-in control

You can control the VP-81KSiusing the front panel buttons, or remotely via:

•RS-485 or RS-232 serial commands transmitted by a touch screen system, PC or other serial controller

•Ethernet over a LAN using a Web browser

•The SI-1VGARemote Step-in Panel

•The Kramer RC-IR3Infrared Remote Control Transmitter or infrared remote extension cable transmitter (optional)

•Remote, contact closure switches

To achieve the best performance:

•Connect only good quality connection cables, thus avoiding interference, deterioration in signal quality due to poor matching, and elevated noise levels (often associated with low quality cables)

•Avoid interference from neighboring electrical appliances that may adversely influence signal quality and position your VP-81KSiaway from moisture, excessive sunlight and dust
