<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.)
Another user asked about splitting from the Controller to the power expander, then splitting again, which I understand is not legal. However, is it legal to just Y from cortex to “in” ports on the power expander as long as only single connection are made from the “out” ports? If legal this could be done twice (two pots from cotrex filling all 4 “in” ports).
I just wanted to verify that it was the second spilt that was not legal in the previous answered question.
