Re: Remtely locating a touchscreen.

I have just done this with 3  of 1024 x 768 vga/serial elo touchscreens.

I used normal cat5 for the serial and screened cat5 for the vga but it
work=
s with normal too.

The links to the serial to rj45 convertors (=A31 each ish)=20

It took a bit of trial and error to work out which of the 9 serial pins to
=
send over the 8 wires of cat5 but I got it in the end.

The vga baluns were from hiddenspeakers.com

I like to terminate both ends of the cat5 with plugs as it makes testing

Max run I have tired is 30ft but should work much longer.

I'm looking to mount a touchscreen in the kitchen (one of these
perhaps:  http://linitx.com/product_info.php?products_id=3D877<http://lin=
itx.com/product_info.php?products_id=3D877>) to my HA
pc in the loft.=20=20

I know there has been some debate over being able to extend over Cat5
in the past but wonder if anyone has successfully done this. I have
one (perhaps 2 - but I'd ideally like to keep the second free) runs of
cat5 from the PC to the screen location. I think I need to extend:

- VGA feed
- USB for touchscreen
- Possibly a second USB for a small local keyboard & integrated
trackball (although I'm not sure if this can be 'linked' with the same
USB as for the screen).=20

Run of cat5 is probably no more than about 15m maybe 20m.=20=20

Any pointers on what additional bits I need and quality gratefully
received.

Richard
