Re: CAN Jaguar: could longer CAN cables cause problems?
Alright, so our CAN Jaguar setup is up and running now.
Solution: We were using flat CAN cables, we switched them out with twisted-pair CAN cables with much more favorable results. If you are a team having CAN issues similar to this, replace your flat CAN cables with twisted pair cables! They help!
Also, apparently our resistors (or at least the one on the tail end) are actually soldered onto the wire instead of crimped, so they are functioning now. I'd advise other teams to solder their resistors as well, as it could increase the lifetime.
When we make our new RS232 CAN cable, we will probably put the terminator at the serial side, since that's what our mentor recommends to prevent extra signal reflection, and to have resistance all the way through the network.
Thank you all for your help and insight!
EDIT:
Apparently we are also getting intermittent connections in our RS232 cable (so the resistor was probably crimped on that end, or it's just dying of old age). Anyway, we're going to make a couple of new ones, then we should have a good signal!
