Jaguar motor contollers stopped working

[djdaugherty]

Our software/electric team told me that they can't mix the black jags and the grey jags when using CAN.... If that's not true, I'd like to know, because the team just invested some bucks in more black jags! It sounds like you were using a mix of black and grey with CAN and they worked at some point, is that true?

There is no reason you could not use both grey and black Jaguars on your CAN bus.

While you can in fact mix BLACK & GREY Jaguars on the same CAN bus, I personally would put all the GREY JAGS in a storage closet for use only in prototyping or an emergency fix where a BLACK JAG wasn't available.

The initial GREY JAGS had several issues, burn outs, melt downs and the like and I wouldn't trust them for use on a competition bot unless I was desperate.

So here is what happened. I had a fully functioning robot, with all motor controllers working. While the robot was one, I tried putting the pins of the female DB-9 into the ports of the cRIO. I tried to enable the robot and noticed none of the motors worked. I am not sure when they all stopped flashing.

A quick thing I just realized is when I turn the robot ON, the brown jaguars that went out flash once before stopping again. If I continue to add different brown jaguars to the end of of the CAN bus, they work.

Thanks for any help,

This sentence confuses me greatly. Female connectors do not have pins that go into anything, and I know of only one cRIO port that can accept a DB9 connector. Can you rephrase it, or perhaps draw a picture of what you mean?

A photo or two of your wiring would help greatly in our attempt to help troubleshoot what's going on.

I'll put up a photo soon.

So for starters, I realized I was doing this all wrong, but I was taking the connectors from inside the RJ12/DB9 convertor and putting them into the pins of the cRIO. I was referring to the the fact that the convertor is a female convertor.

The robot was on, and I did connect the pins incorrectly, so that might have killed it. But I don't think that would short all of the brown motor controllers, and NOT short the black one.

I hope this helps to clear up any confusion.

Thanks,

Omair

I can confirm that you can use both black and tan jags on a CAN network, in fact I did it yesterday. However if you're using serial based CAN (if you didn't pay $200 then you are) a black jag needs to be the first one connected as the tan ones do not have a serial bus. After the first black one they can be any color in the rainbow in any order, as long as it's black or tan.
