I need some help to build remote control lawnmower

I build remote control from electric wheelchair, I try to replace vr2 control system 70A 24V of PG by RoboteQ. I use the lawnmower for hill side that the same concept of wheel chair, that it have electric brakes by If the wheelchair is driven up a hill,there is practically zero roll-back between the time the joystick is released and the brakes are applied. we need roboteQ have 2 output for Brakes and to program them for brakes function.
can you let me know what kind of Roboteq and program of it ?

All roboteq controllers have an output that can be used to release a brake.

The AX... models have one ouput which activates when any of the two motor is running.

The new generation products have two ouputs which can be assigned to each motor channel.

Does anyone knows what pins in the AX3500 controller can be used for electric brakes ? any wiring diagram?

thanks

The digital output is on pin 1 and 8.

This is an open drain ouput. See the manual for wiring info.
