CAN in the 2015 System

I'm trying to help out the programming/electrical squad here.

From how I see it, there's only one CAN I/O on the RoboRIO. We want to use the PCM and the new Talon SRX, but from what we understand both need to be attached to the CAN I/O, but there is only one I/O.

TL;DR How do I connect both the SRX and PCM in CAN to the RoboRIO?

Re: CAN in the 2015 System

You daisy chain. The SRX has 4 CAN wires. 2 go into the roboRIO and 2 go into the next device (in your case, the PCM). The PDP should be at the end of the chain, with the termination resistor jumper set to ON.

Re: CAN in the 2015 System

The CAN bus is daisy chained from one device to another. The PCM has 4 CAN connectors (2 pairs) and the Talon SRX has 2 pairs of CAN wires. Wire (for example) from the roboRIO to the PCM to a Talon SRX (optionally to additional Talon SRXs) to the PDP.

Re: CAN in the 2015 System

Oh. Well duh, we used CAN for Jaguars last year and daisy chained them together. I just thought that since they were two different devices you wouldn't be able to.

Re: CAN in the 2015 System

Is there a special connector I should be using between say 2 talons on the bus or will solding/ quick disconnectors work?

Re: CAN in the 2015 System

Really it's whatever you want. Soldering the wires together also works.
Lots of suggestions here...
