OVERVIEW
Transmit high-resolution graphics over greater distances
with ServSwitch™Brand CATx KVM Extenders.
As with many of the other great products in our ServSwitch
Extender family, these extenders enable you to put more
distance between your PS/2®style server or CPU and your
keyboard, monitor, and mouse (KVM) workstation. With these
extenders, you get a maximum distance of 984.3 feet (300 m)
between the server/CPU and the KVM station.
And you don’t need any special cabling for the extender
connections—standard CAT5, CAT5e, and CAT6 twisted-pair
cabling will do just fine, hence, the ”x” in the product’s name.
The extender kits include local and remote units that are con-
nected with a single CAT5 or higher cable that carries all video
and data signals between the units. All KVM signals (as well as
serial and audio signals on models that support them) are fully
buffered to ensure consistent remote operation of your PC.
Pleasing to the eye.
What‘s most unique about these extenders is that they
bring greater clarity to what you see on your monitor.
That’s because the remote unit (sold as part of a kit or as an
add-on to many of our other ServSwitch Extenders) features
deskewing technology; this equalizes video colors so you get
sharp and clear video at the remote end. Video resolutions
include 1600 x 1200 @ 656.2 ft. (200 m) and 1280 x 1024 @
984.3 ft. (300 m).
The technology does this by addressing a problem
frequently seen with higher grades of UTP cable, on longer
cable runs, and on high-resolution monitors: color drift or
color split. Color drift shows up as that annoying colored
shadow you occasionally see around objects on a video screen.
It sometimes happens with UTP cable because the pairs of wire
in the cable are twisted at slightly different rates to reduce
crosstalk between pairs. Because of these differences
between wire pairs, video signals for different colors often
travel different distances before they reach the remote
receiver. When one color signal arrives behind the others
because its wire is longer, you get that red, blue, or green
shadow around the objects on your video screen.
ServSwitch Brand CATx KVM Extenders remove color drift
by delaying some color signals to compensate for differences
in wire pairs. Skew compensation occurs on all video channels
and colors, resulting in a maximum compensation of 42 ns,
which is sufficient for most applications. This skew
compensation works with all colors transmitted. Even higher
resolutions don’t show visible degradation at great distances.
Such clarity means you can run multimedia presentations
over greater distances without having to settle for less-than-
optimal viewing. We even offer dual-video extender versions
that support multivideo graphics card systems and enable you
to set up a multimedia presentation that can be enjoyed by
more than one user.
Easy to configure and adjust.
The extenders are easy to operate and require no
software. Video tuning and configuration can be done by
entering simple commands on a keyboard that’s attached
to the system’s remote unit. All it takes is a hotkey sequence
and you’re in Command Mode, where you can configure
modes of operation and adjust video for any or all video
channels. The ability to tune adjustments on all video chan-
nels simultaneously is especially helpful when setting up the
multihead versions, which have almost identical cable lengths.

The extenders feature independent low-frequency (LF)
and high-frequency (HF) equalization (EQ) adjustment so you
can fine-tune the video to match your cable type. Tweaking
the LF EQ removes video “smear,” and adjusting the HF EQ
sharpens the image.
The remote units also have built-in Assisted EQ, Channel 0,
and Quick Skew features that can save you time during the
video-tuning process and make it nearly automatic.
Assisted EQ steps through a table of preset LF and HF
EQ values for different cable lengths in 25-meter increments,
quickly setting the approximate EQ for a selected
video channel.
Use the Channel 0 feature to compensate for cable skew
on all channels simultaneously. It’s particularly useful in setting
up large multihead installations where the required adjust-
ments are always the same. We even offer a test card to help
you adjust the skew—just download a copy of the card from
our Web site.
Quick Skew is a one-step skew-elimination function that
sets the color delay to the value that most installations typically
require. Once it‘s set, you can fine-tune the delay further
to your liking. And, often, all it takes is to use Quick Skew
on green.
All settings for the ServSwitch Brand CATx KVM Extender
can be stored in EEPROM memory, so you only need to set up
the system once, and the settings are automatically restored
at power up.
Because the extenders perform full PS/2 keyboard and
mouse emulation, you can boot the PC without having
a keyboard or mouse attached to it. The extenders are
also compatible with Microsoft®IntelliMouse®and other
wheel mice.
Various kits are available.
Our ServSwitch Brand Single-Access CAT5x KVM Extender
Kit (ACU2001A) performs basic KVM extension and features
skew compensation.
With the dual-access model (ACU2009A), you can attach
an additional monitor, keyboard, and mouse to the local unit,
and then operate the PC from either the local or remote user
station. These stations share access on a “first-come, first-
served” basis. You can even use a standard PS/2 mouse at
one user station and an IntelliMouse at the other.
The dual-access local units feature an Enhanced Private
Mode, too. In this mode, a local user can disable the remote
unit or vice-versa.
We also offer models with serial extension and
bidirectional stereo audio extension. These kits, offered as
a single-access version (ACU2022A) and a dual-access
version (ACU2028A), enable you to attach a remote station
with a serial device and place audio devices up to 984.3
feet (300 m) from the CPU. These extenders contain boards
that enable bidirectional stereo audio and full duplex
serial data to be sent along with the KVM signals across
the twisted-pair cabling.
For the serial interface, no setup or adjustments are
required. It transmits six signals (three in each direction).
The audio interface is designed to receive the output from
a sound card (or other line-level) source and be connected
to a set of powered speakers at the other end of the link.
With the audio versions, you can transmit stereo audio
either way across the link. You can even plug a microphone
into the remote units.
To add a second video channel to your system, order
a dual-video version (ACU2201A-R2 or ACU2209A) and get
the same high resolution and skew compensation on both
channels. If you want a dual-video version that also has
serial and audio capabilities, order the ACU2222A-R2 or
ACU2228A extender kit.
As with the single-video models, the dual-video
extender kits use a single CAT5 or higher UTP cable
for transmitting video signals. The dual-video versions,
however, use two copper cables for video channel
interconnects. The first cable plugs into Port 1 on both
local and remote units and carries the primary KVM
video signal; the second cable links Port 2 on the local
and remote unit and carries the secondary video signal.
Or upgrade your existing ServSwitch Extender
remote unit.
If you’re already using a ServSwitch Brand CAT5
Extender and want to enhance your video capabilities
with skew compensation, just order a ServSwitch
Brand CATx KVM Extender Remote Unit to replace your
existing remote unit. These standalone units feature easy-
to-adjust skew compensation and are compatible with
many of our ServSwitch Brand CAT5 Extender products.
