CAN Instructions

Using the CAN bus to control the Talon FX allows users to take full advantage of all its features. To wire the
CAN bus, connect a yellow signal wire to the CAN terminal marked "H" on the NI roboRIO and connect a
green signal wire to the CAN terminal marked "L" on the NI roboRIO.
To connect additional Talon FXs, use the pre-installed connector to connect one Talon FX to another Talon
FX. After your Talon FXs have been wired, there will be 2 remaining signal wires – connect these two wires
using a 120 Ω resistor or to the CAN interface on the Power Distribution Panel (PDP) to properly terminate
the cable end.
If the signal wires are too long, they can be cut shorter, but the end of the wire should be terminated with a
tightly crimped connector to connect the signal wires green-to-green & yellow-to-yellow. For the best
connection, it is highly recommended that each connector is crimped and soldered. The yellow and green
wires should also be wrapped in a twisted pair fashion (not illustrated) to maximize tolerance to electrical
noise.
NOTE: Signal wires of the same color are electrically identical – it does not matter which wire is used if the
color is correct.
