Introduction
The SDBX product range enables high-resolution video, PS/2 keyboard and
mouse, stereo audio, and serial port signals to be communicated up to 300m
over Category 5, 5e, 6 or higher (CATx) cable.
A basic SDBX extension system comprises a Local Unit (transmitter) and a
Remote Unit (receiver). The Local Unit connects directly to the computer (or a
KVM switch system) using the supplied cable(s). The user console (keyboard,
mouse and monitor) attaches to the Remote Unit. The Remote and Local Units
communicate video and data information along the connecting CATx cable
(Figure 1).
Within the product range, models are available with combinations of the
following:
• Audio transmission: bi-directional stereo audio (16-bit digitized).
• Serial transmission: transparent serial COM port (to 19.2Kbps).
• Dual access: allowing a second user console at the Local Unit.
• Multiple video channels: single, dual (and quad) video heads.
