KVM Switches

[Paul Taylor]

One recommendation, if you plan on rebooting your computer remotely or
want to boot up without having to select the computer, get one that
emulates keyboard and mouse. The two Linksys models do not emulate (per
their online ads).

I've been looking around for a KVM switch. Does anyone know about the
IOGEAR MiniView GCS14 Compact 4-port KVM Switch for PC's? Check it out
at  http://www.kvm-switches-online.com/gcs14.html

Thanks,
Paul

I got a 4-port Linksys one that does the proper emulation back to the
computer for less than $50 about a year ago.  Purchased it at
MicroCenter,
and it wasn't on sale.  It's about the size of a paperback book, and
takes
standard cables; it even lets you switch between systems directly from
the
keyboard just like the big fancy ones.

Aside from the funky blue color, and the fact that it turns into kind of
a
mutant octopus of cables when you have 4 systems plugged into it, I
would
recommend it wholeheartedly.  I think this is it:

Hope this helps!

I've been using these at home for years now, and there's quite a range.
You
can easily pay over a thousand dollars for one, or you can get one for
less
than $30.

The mechanical rotary switch type were ok for DOS and VGA or less
monitors,
and they can be used even up through fairly current equipment.  There
are
three drawbacks:  Weak connections due to oxidized contacts make funny
colors and odd mouse/keyboard errors; uneven contact during switching
can
do
weird things to monitor sync, and there's  a chance you can short two
connections together, which may very well fry your motherboard (done
twice).
If you go this route, consider getting more connections than you need
and
leaving one blank connection between each "live" connection for cleaner
switching.

Then there are the passive electronic ones.  These offer clean switching
and
eliminate a lot of the headaches of the mechanical switch.  The only
problem
with these are when you have software that checks for the mouse or the
keyboard.  For instance, if NT reboots and it's not the selected input,
it
will fail to detect your mouse and there's no way to load it.  Mostly
Linux
doesn't have a problem with this, if you're in text mode you just start
GPM
manually.

The fancy ones actually emulate a keyboard, mouse, and P&P monitor back
to
the input/workstations, so even if you boot without being selected, you
appear to have a live mouse.

Price wise, you can get four station passive electronic switches for
under
$100, and you can get decent four station switches with emulation
starting
at about $120.  Shop around, watch the specs, and you should do fine.

I've seen ads in catalogs that implied that the unit could connect to
both
a
Macintosh and a Wintel machine - that's some feat of
emulation/translation.
I've never actually tried one, but they may be out there.  I've also
never
seen a USB switch - that sounds like something that would be very hard
to
do.
