I've got touchscreen which has a VGA output and a USB (or alternatively, serial) connection which acts like a mouse (for the resistive touch part).
I've got Cat5E cabling in my house, and would like to run this screen remotely in my living room connected only to some sort of KVM switch, driven by a computer upstairs in a different room across the Cat5E ethernet cabling, i.e.:
+--------+ +-------+ +--------+ +------+
| Touch +--USB---+ Magic +--Ethernet--|| ... ||-----+ Magic +---USB----+ PC |
| Screen | | Device| | Device +---VGA----+ |
| +--VGA---+-------+ +--------+ +------+
+---+----+
|
Power
Is this possible to do? What is the the "magic device" I need - an IPKVM? I don't want to spend too much. (I could buy a new PC for $200!) I'm quite happy to get my hands dirty with some hardware hacking if necessary.
If it is possible, is it realistic to display (non-HD) video over this link?
Thanks!
EDIT: noticed the screen can take serial (RS-323) instead of USB if that helps.
actually, you still need a computer for the touchscreen, the screen on it's own is rather useless as you cannot assign an IP address to a monitor, the only way would be monitor and USB extensions (with the appropriate range booster). – None – 2009-12-30T11:31:12.250
I don't understand your point about assigning an IP to a monitor. I mearly want to bridge a monitor and USB connection simultaneously over a single ethernet connection - I don't need the monitor to act as an IP address. – Ash – 2009-12-30T11:44:05.797
I guess it would be the magic device which had an IP, do you also use the ethernet cable to internet connection to the PC or would it be just to get the video to the touchscreen? – Jonathan. – 2009-12-30T11:45:36.683
ethernet connections require IP addresses in order to work and if you're thinking about some sort of adapter to use the USB and the VGA signal over the ethernet cable, doesn't work either, it's only 8 leads in a cat5 cable. – None – 2009-12-30T11:48:23.947
