HI!

I am installing one of your ADU5 displays. I would like to connect a RPM output from a MBE ECU which is a 12v switched signal.  
Can the display accept this signal and if so which pin should I connect it to?

Hi Kraig!

You can connect this signal to digital input #1 on the dashboard. Afterward, configure the input as an RPM signal and set the threshold to 2.5V.

For detailed information on configuring digital inputs, please refer to the manual on page 80 at the following link:
