Probably very similar to the KT Display I had, but TBH I cant remember much of setting that up. I just used the printed off manual.

I have one. With a geared motor, it only works when motor is powered up. Must use hall sensors to get speed, and they don't detect when coasting with geared motor. Probably works with direct drive motor.

Vendor could not tell me if the LCD or if his controller has a external speed sensor input. The latter should, but haven't found it.
