User Manual

If you want your microcontroller to have the ability to detect errors from the Maestro using a digital
input instead of the serial command, or you want to receive direct feedback from the user script, then
connect the ERR line of the Maestro to any general-purpose I/O line of the microcontroller. The ERR
line is only available on the Mini Maestro 12-, 18-, and 24-channel servo controllers. See Section 1.b
for more information about the ERR line.
