2. Overview
2.1 Introduction
The ServSwitch Brand USB Micro Extender Series enables high-resolution video, USB,
stereo audio, and serial port signals to be communicated up to 150ft (50m) over Category 5,
5e, 6 or higher (CATx) cable.
A basic USB extension system comprises a Local unit (transmitter) and a Remote unit
(receiver). The Local unit connects directly to the computer (or a USB Hub) using the
supplied cable(s). The user console (consisting of monitor, keyboard, mouse and other
devices) attaches to the Remote unit. All Local Units in the USB Micro Extender Series have
video output ports, allowing a second user console at the CPU (using further CPU/Hub ports).
The Remote and Local units communicate video and data information along the connecting
CATx cable (see Figure 1).
Within the product range, models are available with:
•
Audio and serial transmission: bi-directional stereo audio (16-bit digitized) and
transparent serial COM port (to 19.2Kbps).
• Multiple video channels: single and dual heads.
