Rule <R12> reads:
“<R12> A maximum of one (1) VEX Y-cable can be used per Motor Port of the Microcontroller or Power Expander. (You cannot “Y off a Y” to have more than two (2) motors controlled by the same Motor Port.)
a. Teams using the Cortex Microcontroller can only power one (1) 2-wire Motor per each of the two 2-wire motor ports on the Microcontroller. It is illegal to “Y” off a 2-wire Motor Port.
b. Teams may not “Y” off a Motor Controller 29”
In a hypothetical scenario, we have two 393 motors that we wish to Y together. Is the correct order to do this in putting a 2-wire Y-Cable on the two leads coming out of the motor, then connecting that INTO a Motor Controller 29 which is then plugged into the Cortex?
Is it correct to use a Motor Controller 29 on each of the 393 motors, then use a 3-wire Y-cable to connect the 3-wire ends of the Motor Controller 29s, the end of which is then plugged into the Cortex?
Or is it illegal to use a Y-cable on any two-wire motors?
I just want to be absolutely sure we are not in violation of any rules.
