Digital Input Power

[AHepperla]

When we use digital inputs 1-12, only inputs 1-9 are getting the required 5 volts of power to power inputs, anything after that has .35 volts going through them.

There is no distinction for power to the pins you describe. On only one occassion, one pin failed to have +5 volts of all the robots I have inspected and /or helped troubleshoot over the years. That failed pin had zero volts. There is a possibility you may have a damaged device, but nothing that would give you 0.35 volts on I/O 9-15. There is an internal circuit breaker inside the RC. Is it possible you have devices wired to input 9-15 that might be shorting out the 5 volt supply and tripping the breaker. Can you describe exactly the condition under which you are reading 0.35 volts? Is one of your inputs, failing to operate? If so which one?

My question is what are you using the 5v rail for on your digital inputs... The only digital sensors I know of that need it are the old Optical switches we got in 03/04... if its just a switch it should be wired to ground and signal.
