2. Overview
Thank you for choosing the ServSwitch Wizard DVI/USB SRX extenders. These compact modules present the quickest way to
extend high quality DVI digital video plus USB keyboard and mouse (plus on dual variants, a second digital video channel and
two stereo audio channels) with an additional 2 USB peripherals up to 196 feet (60 meters) away from your computer.
Thanks to our long involvement and investment in extender technology we have succeeded in overcoming the numerous prob-
lems associated with extending digital video signals. Using our proprietary transmission techniques the ServSwitch Wizard DVI/
USB SRX (and dual) modules can reliably transfer video rates up to 165 Mpixels per second. This is in addition to two USB chan-
nels for keyboard and mouse - all via the same single length of Category 5e, 6 or 7a twisted pair cabling.
The ServSwitch Wizard DVI/USB SRX extenders have been designed to be quick to install and totally transparent in operation.
