Hi, I have an old rc5 controller but with only the mini pendant not the full size pendant. If I plug in a monitor to the vga port I can see the same screen as on a full size teach pendant. And when I plug in an ps2 keyboard I can navigate most of the controller using a function key, f1, f2 etc. However I cant click on buttons that aren't mapped to a function key.
I've tried connecting a ps2 mouse to the controller but it does nothing. There is no cursor although the mouse does power up.
Is there a way to get a mouse to work? Or another way to access all the buttons? I thought about a touch screen but not sure if this would work or how to connect it.
