Re: Code Problems
 

Thank You those diagrams are amazingly helpful! I'll be able to let you know if I need help with anything else after next wednesday.

Re: Code Problems
 

We have completely rewired our robot and it will turn on and thats as far as it will go. I need help with the ethernet cable wiring. The situation is as follows:

When we connect an ethernet cable from the laptop to the wireless router, and another one from the bridge to the cRIO, we recieve no robot communication but the ethernet and radio signals on the driver station are both green and the light on the 1st ethernet slot on the cRIO is lit up.

However, when we tether the ethernet cable, (directly from the laptop to the cRIO) we get the same green radio and ethernet signals but the light on the cRIO slot does not light up.

That probably didn't make sense so i've put together some diagrams that might make a little more sense, they are attached.


This probably isn't really clear but if you have any quesions please ask thank you. I am confused and my coach is not that familiar with the wiring on our robot. Any help would be great.

1st: This may be a little simple and looking at your problem probably not the solution, but have you tried using a different Ethernet cable? It just may be you have a bad cable.

2nd: I don't know if you did it just for the picture or what, but are all the modules in for the cRio? In my experience it is generally bad to take them out.

3rd: Try to reset the bridge. It may just be a "frazzled up" in there and need some tuning.

4th: This one seems like the most likely one to me. What did you put as the ip address for your robot? It should be 10.xx.yy.2 , XX and YY being your team number (ex XXYY=3413).

5th: Read through the posts before. Some of those may be it too (router encryption being a big one)

Hope this helps!

Can you say crossover ethernet cable?

Re: Code Problems
 

The fact that the Status light on the cRio stays on indicates a problem there. Check out these Troubleshooting documents http://www.team358.org/files/program...olSystem2009-/
You might have to re-image the cRio.

Re: Code Problems
 

All you have to do for this is just input the team number into the text box on the driver station, correct? If so, then I have done this. However, I waould like to make sure there isn't more to it.

Re: Code Problems
 

There sure is.
You can change the cRIO IP address with the re-imaging tool.
(You don't even need to reformat the cRIO to do this)

Re: Code Problems
 

Well there's your problem :D

Re: Code Problems
 

we got a new cRIO for this year and we tried it in our old robot just to see what would happen. We weren't getting comms wirelessly so we tethered. But both tethered and wireless gave us the same problem: the ethernet and ds radio lights are always green. however, we cant get the bridge light to go on no matter what and so we have no robot comms. the status light on the cRIO is blinking the whole time. We are going to look at the cRIO light indicators tonight but any other ideas are welcome thank you.

Re: Code Problems
 

Have you reconfigured your wireless bridge since it was used in competition? It was set up with a security code at that time. You need to follow the instructions to connect to it using a web browser and reset the security to "none".

How do you reconfigure the wireless bridge?
