CAN connection on roboRio.
 

This is my first year on the Robotics team. I have familiarized myself with the RJ12-Serial connection for the CAN BUS on the cRio.
I was wondering how CAN will work on the new roboRio with Jaguars, since there is no serial port.
Do I only use the CAN - H and CAN - L wires of the RJ12 cable and connect it to the RoboRio?
Should I use a a different gauge wire to connect the wires to the roboRio? If so, would it cause bottle-necking?
Would I need a terminating resistor on the roboRio, or does it act like one itself?

Thanks.

The implementation of CAN on the RoboRIO only uses CANH and CANL. The RoboRIO has an integrated termination resistor.

Would the 2 wires be able to fit the connectors, or should I use a different gauge wire?

The roboRIO has 2 serial ports, but it also has a dedicated CAN interface, so you should certainly use that instead of the serial ports for controlling Jags.

The CAN connectors on the 2015 system fit 16 to 24 gauge wire.

The JAGs have a built in RS232 port that is on the same receptacle as one of the CAN bus ports. Since the RoboRio has a CAN port you will not use the RS-232 port on the JAG. So yes, wire the Can H & L to the jags & ignore the RS-232 port on the Jag. Just like the Jags on the old system that was not directly connected to the Crio.
