Are you willing to take a chance on those "errors" popping up in a finals match?

Students - please take the advice of Ether and others and use CANBus as intended. Terminate at both ends (done for us at one end on the roboRio) only, keep stubs under .3m and total length under 40m. Use shielded twisted pair when possible. The standards exist for a reason - much testing was done to arrive at the numbers in the standards and the designers of the CANBus nodes (on the roboRio, PDP and TalonSRX for example) follow the standards in their designs. Intentional deviation from the standard puts your design in unknown territory probably without the time or facilities to do proper testing. This is most unwise.
