OVERVIEW
You have an IBM PC computer at point A. You’d like to put
the keyboard, mouse, and monitor at point B. Points A and B
aren’t too far apart—maybe only 75, 100, or 150 feet. That
calls for KVM extension, because the system almost certainly
won’t work if you try to run regular keyboard, mouse, and
video cables that far. But you don’t need a big extender that
will cross 1000 feet. So what do you do?
Why not try a ServSwitch Brand CAT5 KVM Micro Extender
Kit (ACU3001A)? The Micro Extenders have the same central
circuitry as many of our more sophisticated KVM extenders—
for example, they support video resolutions up to 1280 x
1024—but they’re specially designed for basic keyboard/
monitor/mouse control across medium distances up to
160 ft. (48.8 m).
The extender consists of a local module to which you’ll
attach the computer CPU with an included three-to-one cable,
plus a remote module that the user-station equipment can
plug directly into.
Connect the local module to the remote module with
inexpensive Category 5 twisted-pair cable. (You might be able
to use CAT5e or CAT6 cable instead; call Technical Support for
details.)
Once your extender system is cabled together, just plug
your remote unit into AC power. Then set a single DIP
switch—to tell the extender whether to equalize for CAT5
cable shorter or longer than 82 ft. (25 m)—and power up
your equipment.
The extender buffers all of the signals that pass between
the CPU and the remote user station. This makes the oper-
ation at the user station so smooth that it will feel like the
computer is right there under your desk.
Just as our bigger extenders do, the local unit always
emulates a directly attached keyboard and mouse. So you can
unplug and replug any keyboard or mouse attached to the
extender at any time without disrupting the booting or
operation of your CPU.
The Dual-Access Micro Extender (ACU3009A) supports a
local user station at the CPU’s site as well as the remote
station. Normally the two stations will contend for access to
the CPU. One station will be granted control while the user at
that station is typing at their keyboard or moving the mouse.
Once this activity stops for two seconds, the user at the other
station can take take control.
The Single-Access Micro Extender with Bidirectional Serial
and Audio Support (ACU3022A) has all of the capabilities of
the regular single-access version, and can also support a con-
nection between the PC and a remote microphone and
speakers (or other sources of audio input and output). Plus, it
offers a serial connection which supports RS-232 devices with
speeds up to 19,200 bps.
Except for CAT5 cable, everything you need to operate a PS/2 type local CPU
with a remote user station is included—just plug in your equipment and go!

WHAT‘S INCLUDED
ACU3001A
• Solid-core 4-pair Category 5 UTP or STP, pinned and
paired according to EIA/TIA-568A or (preferably)
EIA/TIA- 568B, to run from your local module to your
remote module. (Bulk CAT5 cable should be terminated
with high-quality RJ-45 plugs.) If possible, do not use
cable such as Category 5e, “Level 6,” etc. If such cable
is already installed at your site, you will need to install
either a Delay Line Module or a Skew Compensator.
See the Ordering Information and call Black Box for
technical support.
• A monitor for each user station (each monitor must
work when attached directly to any of the CPUs
connected to the extender).
• A standard IBM®PC/AT®or PS/2®keyboard for each
user station where users will need keyboard control.
• A standard PS/2 compatible mouse for each user station
where users will need mouse control.
• An AC power surge protector.
• If you’re attaching ServSwitch family KVM switches:
Compatible user cables and/or CPU cables.
WHAT ELSE YOU MAY NEED
In data communications applications, using products
that exceed required capacities is usually not a problem.
For example, if a 28 kbps modem is required, a 33.6 kbps
or 56 kbps model will work just fine.
But sometimes, more isn’t better. Take KVM extenders
designed to expect CAT5 and only CAT5 cable. You’d expect
that CAT3 cable wouldn’t be effective with these products.
But you may also assume that if CAT5 cable works fine, CAT5e,
CAT6, and other higher capacity cables would work even
better. Unfortunately, this isn’t the case, and here’s why.
KVM extenders from many manufacturers, including
ServSwitch CAT5 KVM Extenders, are designed specifically for
the CAT5 specs defined by the TIA/EIA standard. Higher-level
cables, such as CAT5e, have different characteristics and
specifications. Although differences—specifically twist ratios—
might seem small, they can have a negative impact on these
extenders, which are expecting a true CAT5 transmission.
So with ServSwitch CAT5 KVM Extenders, you can think
big with CAT5—just don’t think bigger.
