3.2 CONNECTION TO THE MASTER AND POWER SUPPLY
• The only electronic connection to the master device is made through the ccTalk bus, through the 10
pins on the interface board connector.
• The ccTalk bus, via parallel 10-way cable, directly connects to the coin validator, the three Hoppers
or Discriminators and I/O interface board. The interface board controls the escrow device, the motor
and recovery button.
• Make the connection with a 10-way ribbon cable of the necessary length. It should not exceed 3
meters in length.

Power supply
The Combo-T device is powered from the ccTalk connection. Ensure that the power supply from the master
provides the correct voltage for the operation of the equipment.
• We recommend a power supply to provide at least 4 amperes of current.
• It is necessary to take into account that if Discriminators are used, they will only work at 24VDC.
