I have just received the display unit and it has only been on the way to the Netherlands for about 1.5 weeks!
I hooked it up as described but it doesn't get any further than The Warning picture.
The SDS200E sees the cable and I confirm the serial connection with "."
But then nothing more happens.
Am I missing something ?
Can you email me at rayers@touch-scanner.com? I can walk you through the settings.
