Typical Application

CrystalView Plus USB application


CrystalView Plus USB KVM extenders enables you to position KVM stations up to 1,000 feet away from computers over CATx cabling.

In order to simplify control over video, CrystalView Plus USB has eliminated adjustment knobs and jumper switch settings. Integrated controls that adjust for skew, low and high frequency equalization, and RGB delay for each channel are easily adjusted using keyboard commands compatible with almost any operating system.

Channel settings (single or dual) can be adjusted individually or universally, allowing for a high degree of flexibility and quality.

The stereo audio option produces low-noise and high quality sound. Speakers, headphones, and a powered or un-powered microphone can be connected to the remote unit, making it suitable for a wide range of business applications. The bi-directional serial option allows you to connect a touchscreen, digital tablet, serial printer or other supported serial device to the remote location. No set-up is needed; just connect the serial device to the serial port and it is ready to use.
