The previously posted answer for turning off term.res jumper and terminating manually with a 120Ω resistor is correct. Since the CAN harness is just two wires it's pretty easy to solder a single resistor and heatshrink it.
kiettyyyy, did you void your TALON SRX's warranty on purpose?
To kiettyyy's point, it's nice putting the PDP at the end instead (I like effortless solutions!). But I understand not every robot has the luxury of having the PDP at the end of the chain. I'm sure prifken's team will make the best decision based on what they want to do.

The physical location of the CAN device does not have to correspond to it's place in the daisy-chain. The OP could have installed the PDP with two motor controllers on either side, connected from the RoboRio to one motor controller then from motor controller to motor controller until he reached the fourth then connected the fourth motor controller to the CAN Bus terminals of the PDP and enabled the termination resistor on the PDP. The CAN Bus wires would be looping back from one of the motor controllers at the end.
