The
ServSwitch CAT5 KVM Switching Extender
(ACU1049A)
is similar to the regular extenders in that you can place your remote
workstation nearly 1000 feet (304.8 m) away. It, too, features
keyboard and mouse emulation and video equalization.

The ACU1049A is also a switch. It enables the remote station
to switch between the local CPU and remote CPU with a simple
keyboard code. Its Double Private Mode locks out the second
workstation, preventing conflicts.
Versions for single or dual access, plus serial extension.

With the
ServSwitch® Brand CAT5 KVM Extenders
with Serial
Extension, you can place a VGA monitor, keyboard, mouse, and a serial
device (such as a modem, printer, or touch screen) as far as 1000 feet
(304.8 m) from your PC’s CPU. Now you can operate your PC from
almost anywhere in the same building.

The
ServSwitch Brand CAT5 KVM Extenders
with Serial Extension
enable you to connect just about any standard asynchronous RS-232
peripheral—including trackballs and serial mice—that operate at up to
19.2 kbps and don’t require any control signals other than RTS, CTS,
DSR, and DTR.

serial extension.
With the dual-access models (ACU1008A, ACU1028A), you can
attach an additional monitor, keyboard, and mouse to the local unit.
The PC can then be operated from either the local or remote user
station. These stations share access on a “first-come, first-served”
basis. When there’s no keyboard or mouse activity on one station for a
certain amount of time, the dual-user extender switches automatically
to the first station from which it detects a keyboard keypress (or mouse
movement, if you prefer). The “inactivity timeout” prevents a user
at the other station from interrupting work in progress at the active
station. (NOTE: KVM contention has no effect on the serial
communication between the CPU and the remote serial device.)

For applications in which your remote station isn’t in a secure
location, the local user should set the extender for “private mode”
operation, which disables the remote monitor, keyboard, and mouse.

The ACU1022A and ACU1028A models also provide audio-
extension capabilities. With them, you can place audio devices, such
as speakers, micro phones, and headphones, up to 1000 feet (304.8
m) from the PC’s CPU! Through this bidirectional stereo audio interface,
sound can be transmitted in both directions across the link at the same
time. This way, you can listen to near-digital-quality audio from the
CPU via speakers attached to the remote unit (on the single-access
version) or both the local and remote unit (on the dual-access version).

Just about any standard PC sound card or consumer audio device
that doesn’t transmit or receive signals at voltages above line level
(5 volts peak-to-peak) works with the audio exten ders. And, as with
the KVM and serial signals, the audio signals transmit fully buffered.
No-hassle setup and operation.

No-hassle setup and operation.
Setup is easy. Start with a simple configuration of your extenders.
This is done using several internal controls. You may, for instance, have
to adjust jumpers to work with the distance of the CAT5 cabling run
between the extender’s local and remote units. And, for the extenders
with audio capabilities, you may need to amplify microphone input
from the remote site.

As for the rest of the setup, connect the local and remote units
to each other and to your equipment, adjust your video compensation
as necessary, and you’re ready! The extenders are simple to use and
require no software. And, other than a few keyboard-command
functions, they operate automatically and transparently in most cases.

mouse emulation, you can boot the PC without having a keyboard
or mouse attached to it. Your PC will boot even if an extender’s remote
unit is not powered or if no keyboard or mouse is connected to the
local or remote unit. You can also “hot-swap” the remote or local
keyboard and mouse at any time; that is, you can unplug and replug
the keyboard and mouse without disrupting the operation of the PC.

The extenders are designed for use up to a maximum cable length
of 1000 feet, and at this length, the video quality should be acceptable
even at a screen resolution of 1024 x 768 and a refresh rate of 75 Hz.
To fine-tune the image more, the extenders feature fully adjustable
video equalization to compensate for the loss of image quality caused
by the signal passing through long cable runs. Jumpers on the remote
unit‘s board enable you to configure an equalization-adjustment range
appropriate to the length of the cable connecting local and remote
units, and rotary controls on the remote unit enable you to adjust
the compensation level while the system operates.

To save even more space in your application, you can rackmount
the extenders using a 19" Rackmount Kit (RMK19U-R2 or RMK19X),
which enables you to place an extender unit in 1U of vertical space
within a 19" rack.
