C Control PRO-BOT128 + C-Control PRO 128 Unit + Voltcraft® USB programming cable Kit 190406 Benutzerhandbuch

To enable the PRO-BOT128 to attract attention, it was equipped with a sound converter. This component consists of a piezo element on the
inside, which converts the electric voltage to sound.



Observe the polarity indication on the sound converter (plus/+ and minus/-) and solder on the part in line with the equipment imprint
on the circuit board.

LS1 = sound converter (cylinder-shaped housing)

A capacitor microphone is required for sound detection.

You may have to solder on two small wires here if these are not available already.



Also observe the polarity with this part! If you take a closer look, you will see that one contact is connected to the housing of the
microphone. This indicates the ground (GND, "-").

Mic = EMY 62



The buttons only fit exactly into the soldered contacts in one position (in the "wrong" position, you would have to bend the pins).

SW2, SW3 = MTS602 (small square button with four pins)

SW1 = slide switch
