New vex cortex and motor controllers

My electrical team has been looking at the new cortex, 4 wire “phone jack” they wonder how we will connect the “phone jack” to a PWM motor controller…cut the wire, special adapter, other? thanks

I think you’re talking about the v5 system. Ports A-H, opposite the power button, are standard PWM ports.

The above two posts are correct and have good information.

The 4P4C connectors (the phone jack cable) are for RS485 communication. You can’t splice a PWM cable onto the end of the V5 Smart Cable (the phone cable looking cables) and use it to control motor controllers. It’s a completely different way of communicating.

The only ports that can output PWM are the ones @Taylor mentioned above.


@bernieseaholm Also look into purchasing the 3-wire expander when you run out of ports.
