System Overview
The CrystalViews two Units, (Local and Remote) work together to extend the
distance between a KVM station and a CPU. Up to 1,000 feet of
CAT-5 cable can be used to connect the two units.
The Local Unit connects to a CPUs Keyboard, Video, and Mouse ports with the
appropriate CPU cable. The Local Unit communicates data from the Remote Unit
to the CPU and CPU to the Remote Unit. Power is provided to the Local Unit
from the Keyboard port of the CPU, eliminating the need for an external power
source. The Local Unit is available in two versions, a Single Unit and a Dual Unit.
The Dual Unit allows for a second KVM station to be connected to the Local Unit.
The Remote Unit connects directly to the PS/2 Keyboard, Video monitor and the
PS/2 Mouse cables of your KVM station. The Remote Unit sends Keyboard, and
Mouse signals to the Local Unit, which in turn, sends the signals to the CPU.
The Remote Unit adjusts Video brightness and sharpness and provides Video
equalization settings to enhance the image quality. Power is supplied to the
Remote Unit from an external power transformer.
Both the Single and Dual models have serial and audio capabilities. The audio
option allows you to transmit the “Line Out” audio from a CPUs sound card to
speakers or headphones connected to the Remote Unit. You can also connect a
microphone to the “Line In” connector on the Remote Unit.
The Serial option allows the CPUs DB9 serial ports data to be transmitted to the
Remote Units serial connector.
Figure 1 shows a typical configuration using stereo audio speakers, a
microphone and a serial device. The installation section explains the proper way
to connect and install these.
