I picked up a used touchscreen monitor in hopes of playing with the idea of using it on some of our equipment. Either the lasers or the CNC router. They guy was most helpful and said if it didn't work, he'd give me my money back and left all his contact details with me, so I think I've got nothing to lose (especially since I didn't pay much for it).
It's a ELO touchscreen monitor.
Out of the bottom, there is the blue, VGA plug and a green 9 pin serial plug. The guy said "You'll have to buy that touchscreen cable from ELO", which is the green one.
We called ELO and asked if the cable was special and they said it was just a straight through 9 pin. Cool, we have those.
I don't understand how it's supposed to be hooked up (mainly because of the instructions the guy told me). Am I supposed to hook up the VGA to the VGA on the computer and then the serial to the serial on the computer? Is that how those things work? He indicated that you didn't use the VGA, just the green serial connection. But I can't see how plugging a serial connection into the serial port is going to drive video. So am I right in thinking that you have to hook up both of them, one cable drives the video and the serial actually handles the touchscreen part of it?
I've never seen one or played with one before, so it's all greek to me.
