The Handheld Control Box connects to the Main Control Box via a length of CAT6 cable. The control box uses a Pololu Micro Maestro 6-channel USB Servo Controller from ServoCity. The programmable Micro Maestro takes input from 3 center detent potentiometers (position, speed, tilt functions) and translates the analog voltage at the wiper of the potentiometer into standard RC signals.These signals are connected to a ServoCity CAT6 Sending Board (non-boosted). The CAT6 cable connects to the Main Control Box’s ServoCity CAT6 Sending Board (boosted).
