how do I push a button remotely (second post)

hi, sorry this post may not appear in the thread it should. I only
have access to google to post, (no newsserver) and google says it's
'unable to retreive the message' (google fails like that sometimes).

I should have given more info.
The device is a KVM Switch (also known as a CPU switch)

meaning: (plug many computer boxes in and then plug in one actual
Keyboard Video(monitor) and Mouse, and you can switch between them -
choosing which computer to access).

The button on the KVM Switch will let me cycle between computers.

The KVM switch is connected to a KVM Extender which boosts 30 meters,
hence the KVM switch is downstairs.
meaning: The system I have, is that the KVM Switch - instead of
plugging directly into a Keyboard monitor and Mouse, is plugged into
a KVM Extender - boosting the signal along a 30 meter cable, into my
room, where my Keyboard monitor and monitor plug in.

I opened up the KVM Switch to have a look. Posts mentioned something
about 4 contacts, I can see them. I could find the correct pair (via
experimenting with a screwdriver or little wire, to see which
activates the switch), and then I could solder one end of a wire to
those 2 contacts, and the other end to an actual switch.

The KVM switch does plug into the mains.

Should I use 30 meters of shielded cable or just normal wire? I have
heard that normal wire may act like an antenna and confuse the kvm.
Though i've also heard that normal wire is fine 'cos it's just a
switch.

I intended to get 24AWG wire - shielded, but the technical sales guy
was convinced that I didn't need shielded, and that shielded would be
harder to solder on. He didn't have the info available to him to tell
me what the AWG of the wire he sold me was, but he said it'll be fine.

thanks

 

First RTFM.
If you had RTFM, you would realize that the KMV has a feature that allows
you to press some keys on the keyboard to change the active system.

Go read your KVMs manual and find the easiest and cheapest solution.

 

my kvm extender does not support the hotkeys offered by my kvm switch

James Hanley formulated on Monday :

I have a Linksys KVM and double clicking the lefu ctrl key on my
keyboard switches it witgout having ro fish around for the button. If
yours dosn't do that..try the linksys switch.
