Powering the touchscreen of my Megatouch MAXX

[wrecksus]

Hi there,

I bought some old megatouch maxx cabinets in the hope to use them as touchscreen cabinets running windows.
I've gutted the insides and managed to get the machines working when attached to my own windows 10 machine (albeit at an awful resolution due to the CRT but what can you do?)

The problem I now have is that my machine does not recognise the touchscreen when it comes to calibrate it.
I think it's something to do with this wire (see pic)


I have naturally connected the serial port to a serial port on the new PC but this extra piece doesn't seem to go anywhere?
Judging by the connector on the end of it, i thought it was just there to 'earth' the connection but now I'm starting to believe that its made to be powered?

Can anyone help?
Pics attached of the cab for reference.

Earth ground. If there is no spot on metal where it goes, it could have been looped inbetween the bolts to hold the connector ends together.

Okay, that makes sense.

Does the touchscreen get powered by molex exclusively or could it be wired to something else?

I didn't see a connector for it is all.

My old megatouch machines connected via serial port.
I swapped in a serial port ELO touchscreen and it worked fine.
The ELO would also work on Windows XP with the serial ELO drivers and software installed.
So you might try those drivers.

Windows 10 is probably pushing it.  Definitely not going to be plug and play.

I will definitely give XP a go next.

It's strange because the drivers detect the touchscreen on the correct serial port during install but when I open the calibration software it just gives me this screen (see pic).
