Cable type and distance rules
• Cable screening is paramount. The best cable
screening specifications for digital KVM extension are:
S/FTP, S/STP or PiMF.
• Extension distances up to 50m are supported with
single uninterrupted runs of recommended cable
(Black Box CAT7a patch cable) at full resolution.
• Extensions of 50m may be achieved with single
uninterrupted runs of shielded CAT6a bulk/trunk (not
patch) cable at full resolution.
• Black Box does not recommend CAT5e cables for use
with this product.
• Overall cable runs must be reduced by 5m for each
additional cable coupling.
• Run specifications may be increased by 10m when
using resolutions of 1280 x 1024 or lower.
• All patch cables should be as short as possible and
should be no longer than 2m.
• It is recommended that Black Box CAT7a patch cables
are used for maximum performance.
2. Welcome
Thank you for choosing the Black Box Dual Link DVI/USB Extender SRX units. These compact modules provide the quickest way
to extend high quality dual link DVI digital video plus USB keyboard, mouse and stereo audio with an additional two USB periph-
erals up to 165 feet (50 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 these modules can extend all
dual link video resolutions up to 2560 x 1600. In effect, these modules can reliably transfer video rates up to 330 Mpixels per sec-
ond. This is in addition to multiple USB channels plus stereo audio - all via the same single length of CAT6a or CAT7 shielded
twisted pair cabling.
The Dual Link DVI/USB Extender SRX modules have been designed to be quick to install and totally transparent in operation.
