Well for one, that's not FRC Legal. *Standard warning about 2016 rules may not apply to 2017* See rule R70:
Quote:
Each Jaguar or Talon SRX must be controlled with signal inputs sourced from the roboRIO and passed via either a PWM (wired per R68) or CAN-bus (either directly or daisy-chained via another CAN-bus device) signal, but both shall not be wired simultaneously on the same device. If the CAN-bus configuration is used, the firmware on the device must be updated to at least the following versions:
You can only either directly connect to the roboRIO or daisy chain through another device.
