Manage a few IBM PS/2 or
PC/AT compatible CPUs—
plus one or two Mac CPUs—
using a single keyboard,
monitor, and mouse.
ServSwitch Jr .:
Access up to eight
IBM PC/AT or PS/2
type CPUs with a
single monitor, PS/2 or
PC/AT keyboard, and
PS/2 or serial mouse.
ServSwitch Jr .MP:
Access one or two
IBM type CPUs and
one or two Mac CPUs
with a single monitor,
PS/2 keyboard, and
PS/2 mouse.
Both Models:
Use any of a variety of
video types at resolutions up to 1600 x 1280.
Key Features
I
f you’ll only need to switch
between up to eight PCs or
servers for the foreseeable future,
why spend a fortune on an
electronic keyboard/video/mouse
switch with a myriad of ports or
fancy cascading features?
Our ServSwitch Jr.
™
is just
right for small-scale applications
such as workgroups, small
offices, or home offices. Use one
monitor, keyboard, and mouse
to control IBM
®
PC compatible
(and, on MP models, Apple
®
Macintosh®compatible) computer
or server CPUs.
With the ServSwitch Jr.
(non-MP version), access either
two IBM type CPUs (with the
SW621A-R3) or as many as eight
(with the SW629A-R2). With the
ServSwitch Jr. MP, access one
IBM type CPU and one Mac
®
type CPU (with the SW627A-R2)
or one or two of each type (with
the SW628A-R2).
Setting up is easy. Using
their own cables, plug your VGA
or XGA monitor, keyboard,
and mouse directly into the
ServSwitch Jr. Attach each of
the computers to the switch using
a special CPU adapter cable that
has a single connector on the
switch end and three connectors
(for keyboard, mouse, and video
I/O) on the computer end. These
CPU adapter cables help keep
cabling simple; also, the coax
versions can be run longer
distances than normal keyboard,
mouse, or video cable.
As long as you use the right
type of CPU adapter cable, it
doesn’t matter what general type
of keyboard and mouse any given
IBM type computer uses. As for
user-station equipment, use a
regular or wheel-type PS/2
®
mouse and PS/2 keyboard with
the ServSwitch Jr. MP. With the
regular ServSwitch Jr., attach
either a PS/2 or PC/AT
®
style
keyboard and either a PS/2 mouse
(regular or wheel type) or (if there
are no PS/2 type CPUs attached)
an RS-232 mouse. Except for
RS-232 mouse input to PS/2
mouse output, the switch can
perform all of the various
conversions internally.
The switch also seamlessly
handles VGA, SVGA, or XGA
video at resolutions up to 1600 x
1280 pixels, although higher
resolutions, refresh rates, or
distances will require coaxial
CPU adapter cables. On non-MP
models, using coaxial cables will
also give you the ability to display
RS/6000
®
or SGI™video. On MP
models, to get Mac video in
resolutions above 640 x 480 pixels,
you’ll need the Mac Adapter for
ServSwitch (KV99MA).
To switch between CPUs,
either press the port-selection
buttons on the switch’s front
2
panel or send switching
commands from the shared
keyboard. (Other keyboard
commands control port scanning
and configuration functions.

Specifications
Configuration settings can be
saved in nonvolatile memory, so
they’ll be preserved even if the
switch loses power.)
The ServSwitch Jr. doesn’t
even have to be plugged in—
it draws its power from the
keyboard and mouse interfaces
of the attached CPUs, while the
ServSwitch Jr. MP has its own
external power supply. And both
are small enough to fit on a
cramped desktop or even in one
rack unit (rackmount kits are
available).
