Title: Any use for this touchscreen??
Post by: Peja on January 11, 2012, 01:08:04 pm

Long story short.....I have a about 6 or 7 of old touchscreen POS terminals laying around in my spare office.  These are 12 inch monitors that use the ELO drivers to ring in food/drinks in our various restaurants.

I am just wondering if I can use the monitor and hook it up to a home computer as a touchscreen jukebox.  I am just not sure about the connections.  The POS terminals are IBM 4840-533 Kiosk terminal which do not have a sound card in them and the hardware is severely lacking.....celeron/256mb memory etc. 

Here are pictures some pictures of the type of connection it is.  It looks proprietary but I could be wrong and maybe there is an adapter.  Is it even worth messing around with a little 12inch screen?  It is free after all.....

If anyone has any ideas, please let me know.

Thanks

I would say that is a proprietary interface. Personally I would probably give this one a miss, although someone else may have better ideas.

Full specifications and tech sheet available here.

Just looked through the DOC PDF, and that looks like the external disk drive connector and not the monitor connector. Maybe that's not the right PDF manual for that unit?

Mainly I was just curious. It may be that the signalling is standard VGA, just in a different cable package, but you'd likely have to cut and splice video cables to make an adapter. Not hard but not trivial either.

And you'd have to find the right pinouts first.

Free is good, but if it's a bunch of work, for a 12" screen.... I dunno

Hmmmm that is the right data sheet....it is the 4840-533 with the celeron processor and no audio.  That cable is definitely the video cable as it is the only one that goes up to the monitor....the monitor is attached to a metal bracket to the computer housing so there aren't any other cables behind it.  Plus when I unplug that cable, the monitor goes black until I plug it back in. 


I think drnick may be right as it being proprietary but drventure (lots of doctors in here) may be onto something with it being just a vga package.  But yes it may not be worth it when you can get a 23" touch screen for a little over 300 or smaller for less.

Thanks for the ideas guys....was just hoping there was some kind of video adapter out there I didn't know about.

Yeah, if you could find an adapter to a standard VGA plug, that'd be ideal. But, being IBM, I'd bet that adapter will cost you dearly if they even make it  :(
