This is how are pins are set, is this correct???

Re: SIGNAL LIGHT WONT WORK
 

That photo shows all the cRIO's DIP switches set to the off position, which is the way they should be for most teams' normal operation.

It also shows no power or data connection, and it has obviously been edited, which is a little confusing.

Re: SIGNAL LIGHT WONT WORK
 

Dave,
Since we are grasping at straws anyway, the next step would be to exercise the switches with the power off. Every once in a while, a switch gets a little dirt inside and it needs to be cleared. Hey, it's worth a shot and only takes a few seconds.

Re: SIGNAL LIGHT WONT WORK
 

this thing is driving all of you guys nuts im sure,
im not even on your team and it bugs me!

whenever you download code or re-image, has it said its been successful?
have you attempted to download code/reimage from a different computer?
have you been downloading wirelessly or through cat-5?
make sure you are using a normal cat 5 or cat 6 cable, not a crossover.

at this point, im just throwing out things, hoping one simple little mistake is all that it is. I believe you used multiple cRios to test this, its hard to believe that more than one would have the same issue... Mark, Al, or Alan, would it be probable to use the little reset button on top of the cRio before imaging and downloading code? If so, is there a proper order of operations to do such? ie hold for a certain amount of time, or until a certain LED flashes in a certain pattern?

I am fairly confident in this teams abilities as to getting everything wired properly and connected correctly by this point, we have gone through most of the hardware errors that i can think of. I believe its something in the code/cRio that is giving the problem.

Maybe go through your Digital cRio modules and slot 4 in your cRIo, and check for anything that may have shorted them out. One shorted module may have shorted out the slot in your other cRio maybe? also causing the shorting of all the other modules that were plugged into that slot? i dont know how practical that is, but its a possibility. Once again, can Alan or Mark back up this theory? It would be unfortunate, but the warranty may cover it if that happens to be the problem. Also check the DB37 cable for any shavings inside that may have put two of the pins in contact. That may have also fried the modules/slot...

At this point in the season, would it be practical to send the cRio back to NI? they overnight replacements for you i believe if you are having issues and send the other one back.

Re: SIGNAL LIGHT WONT WORK
 

Samir,
I defer to Mark or Alan on software/Crio questions. I am just approaching this from a troubleshooting angle since that is what I play in real life.

Re: SIGNAL LIGHT WONT WORK
 

I'm stumped.

All I can think of to try right now is to start over and ask all the usual questions again, on the slim chance that whoever answered them the first time didn't fully understand what they meant or didn't look closely enough at the system to answer them correctly.

Question #1: when the system is powered on, what is the state of the three power status LEDs lit on the Digital Sidecar? BAT, 5V, and 6V should all be on brightly.

Re: SIGNAL LIGHT WONT WORK
 

We ran into this same problem and methodically checking every connection resolved it for us. It turns out that someone plugged the pneumatic pressure sensor into the wrong location.

Re: SIGNAL LIGHT WONT WORK
 

Have you installed the cRIO gaskets?
The reason I ask is that process includes cleaning out any accumulated metal dust that may have collected inside the cRIO.

Re: SIGNAL LIGHT WONT WORK
 

I had a similair thought, but i found it rather odd that both cRios were performing in the same manner. I am correct as to you having two cRios right?

Re: SIGNAL LIGHT WONT WORK
 

OK,
I am reaching back into 2009 on this. It seems to me that the DSC power LEDs can come on dimly even if the power supply wires are not connected. Does anybody remember that? An old mentor of mine used to say..."When you have checked everything else, check the power supply one more time." I would pull the connector out of the DSC and measure the power at the DSC side of the connector. Tug on the wires and see if they pull out.

Re: SIGNAL LIGHT WONT WORK
 

The DSC gets a very little power from the 37-pin cable that can make some of the lights glow, and even that dimly, in the absence of power through the Wago.

Think about what you haven't tried changing, maybe because it was so obviously right by just looking at it.
Maybe a new Wago connector with new wiring back to the Power Distribution Panel, and get someone different to wire it.

Re: SIGNAL LIGHT WONT WORK
 

IT WORKS!!!!!!!!!!!:yikes:
We removed the entire electronics board from the robot and removed EVERY WIRE AND COMPONET! (For the 3rd time) I then wired only the power board, cRIO, cRIO module 9403, and a DSC. The signal light still didn’t work so I imaged the cRIO and the light work! I changed the wire from the power board to the DSC to 14 AWG (it was tough to fit in the wago connectors but I did it)!

Thank you all for your help, especially 1257 for inviting us to their shop and testing our components!

Re: SIGNAL LIGHT WONT WORK
 

Peter,
It is great that you got it working. I would suggest you replace the #14 with the #18. I only say this because the larger wire would be prone to having a strand move over and touch the other wire, shorting the power supply. The #18 will give you that extra margin of safety to keep everything alive. I am very glad you got it working.
