The Premium KVM Cables come in two types: User Cables, designed to extend the
distance between a switch and a set of user equipment (keyboard, monitor, and
mouse); and CPU Cables, designed to extend the distance between a switch and a
CPU or another switch. Premium KVM User Cables (product code EHN409) come
in 10-ft. (3-m), 20-ft. (6.1-m), and 30-ft. (9.1-m) lengths. Premium KVM CPU
Cables (EHN408) come in 5-ft.(1.5-m), 10-ft. (3-m), 20-ft. (6.1-m), 30-ft. (9.1-m),
and 50-ft. (15.2-m) lengths.
Both types of cable are built to the special three-in-one design shown in
Figure 3-7 on the next page. The central coaxial video strand of each cable is
molded to the keyboard and mouse strands on either side, and the ends of its
video strand are one inch (2.5 cm) longer than the ends of the other strands, so
that the weight of the composite cable can be borne by the video connector’s
screwlocks. To help you tell the otherwise identical keyboard and mouse strands
apart, they’re labeled “K” and “M” respectively. Also, at the time of this writing, the
keyboard strand is colored orange while the mouse strand is colored green, but the
colors of the strands or connectors might be changed at some point to conform to
PC-interface color specifications such as PC99.
We offer several types of ServSwitch Brand KVM Extenders. At the time of this
writing, there are three models that you might want to use to extend switch-to-user,
switch-to-CPU, or switch-to-switch distances in a ServSwitch Duo/Quadro system:
• The ServSwitch Brand CAT5 KVM Micro Extender (product code ACU3001A)
is suitable for runs up to 50 m (160 ft.).
• Depending on your video resolution, the regular ServSwitch Brand CAT5 KVM
Extender (ACU1001A) can be suitable for runs up to 300 m (1000 ft.).
• The ServSwitch Brand Fiber KVM Extender II-SM (ACS251A) is suitable for
runs up to 10 km (6.2 mi.).
With the regular Extender and Micro Extender, you’ll need CAT5 cable to run
between the Extender’s Local and Remote Units, plus special cable to connect the
Extender to the CPU or Duo/Quadro. For Duo/Quadro-to-CPU runs, you might
want the Dual-Access regular Extender (ACU1009A) or Micro Extender
(ACU3009A), which supports a local user station at the CPU that contends with
the Duo’s/Quadro’s user station for access. With the Fiber Extender II-SM, you’ll
need a duplex single-mode fiberoptic cable to run between the Extender’s Local
and Remote Units. Call Black Box Technical Support for help planning an
Extender-assisted ServSwitch Duo/Quadro system.
