Incorrect voltage readout on Driver Station

[wireties]

Ours is reading zero also. I have swapped analog modules and breakouts and the jumper is in the correct position. We are playing with custom dashboard code at the moment and getting message errors. Could that be messing it up?

TIA

It would greatly help us help you if you could take a clear photo of your analog breakout while the problem is occurring and post it here, showing the jumper and the wiring connected to it.

photo attached - sure looks correct

It looks okay...except for the lack of any indication that there is actually power applied. There's a green LED that ought to be lit. What voltage do you see using a meter on the white Wago connector?

Sorry - the power was not on - the green LED is on when power is applied - we see 12.07V on the wago connector. It must have something to do with the dashboard packet format not matching (because we are customizing it).

Customizing a dashboard will not break the robot battery voltage communications. They are very independent.

The problem became obvious once I realized what to look for.

Keith, your NI 9201 module is in Slot 8 of the cRIO chassis. It needs to be in Slot 1, at the end nearest the Ethernet ports and power connector.

Hmmm - I'll check it tomorrow. I thought it was in slot 1.

Thanks

Thanks Alan - the students swapped the cRio mount around and I did not even notice - an acute case of cRio slot dyslexia!!

All is good now!
