The hand box connects to the main ScopeDog control box via a standard USB cable.
A light touch joystick gives precise motor control. Moving the stick on the diagonal engages both axis drives.
A button on the joystick lever cycles through the three speeds. The two LEDs indicate what speed is selected.
The toggle switch engages a spiral search pattern. During ‘GoTo’s this switch performs an emergency stop.
