Not sure if this is the right place, but we’re desperate.
We will be taking part in a competition tomorrow (11/13) and our cRio does not work on occasion. Every time we kick, the cRio essentially dies. Our bridge establishes wireless communication with our driver station, but it cannot establish ethernet connection the cRio. Does anyone have any suggestion on what we can do to fix the problem? Please help as soon as possible. Thanks in advance.
Have you checked all connections to make sure they’re tight?
The fact that this happens only after you kick seems to indicate that something is getting jostled loose, or that power is getting drained. I’d look particularly closely at the bridge-cRIO cable and ports, and the power connections on the cRIO, to make sure that they’re working and secure.
We’ve determined that the breakdown occurrs between the bridge and the cRio. The lights around the ethernet ports (a green and/or yellow) do not light up which leades me to believe that something has been knocked loose in the cRio.
Also, the indicatore light (the big orange one) does not turn on after this happens. Next time it occurrs, I’ll take some pictures so you all can see what I’m attempting to describe.
Sounds like you may have a loose ethernet connection on the cRIO side. I don’t know if there is a fix for that; someone else might. There are ways to help prevent this, but they may not work against all possible cRIO impacts.
Joe covers most of the bases but if you still are having trouble try a small screwdriver handle (the insulated part) tapped lightly against the side of the ethernet connector on the Crio board. An over anxious student may have lifted the connector off the board. In general these are not easily repairable and certainly not for someone who doesn’t do this on a daily basis.
Also be extra sure that the power connector is terminated properly. If you think it might be a problem, reterminate. I have seen more than ten teams who have had a small whisker of wire shorting out the power supply input to the Crio. Give it a tug test when you are done.
