What do I need to do if our Talon SRX is blinking red? It’s Using CAN. I’ve read all of the other posts but still cant figure it out. We’ve re-wired our robot so our wires are a bit all over the place. There could be a possibility I placed them wrong. But when I search how to wire it, nothing pops up. Bit of a newbie to wiring.
How do you have your CANbus wired?
It should be from RIO to Motor controllers such as Talon SRX to PDP/PDH
FIRST also provides detailed wiring instructions.
There are LEDs on both sides of the Talon. When they are blinking red, is it
- one side is red and the other side off, then flipping such that they are red and off, but the other way around – or –
- both sides are lit up red at the same time and then off at the same time
Pattern 1 is an indication of a CAN problem. Pattern 2 is an indication that the Talon is being commanded to output in reverse.
Assuming that it’s pattern 1, make sure that your CAN wire is always connected yellow-to-yellow and green-to-green whether in the connectors on the components or when connecting wire-to-wire. Be sure that you have the terminating resistor ON in the Power Distribution Panel or Power Distribution Hub, whichever you are using.
There’s one for CTRE products too, for some reason I can’t link it
If it is Pattern 2, as Paulonis described, it may be a programming error. The controllers are designed to go to the off-state if they are not getting commands via the CAN bus.
