The CBA-2 was designed to be used in vending and amusement/jukebox applications. Different harnesses and wiring allow you to configure it to your particular needs.
Seperate service/parts manuals were issued depending on application.
For vending machine and universal applications use manual # 25520901.
For jukebox and amusement game applications use manual # 21922101.
This bill acceptor operates on 12 volts DC.
There needs to be TWO harnesses from the bill acceptor to your game/jukebox/vending machine cabinet.
One harness is the 12 volt DC power to the bill acceptor. Part # 0030789 Power Harness Assembly can be ordered from any Rowe distributor's parts department. It connects to connector P2 on the bill acceptor's control board. Pin 1 is the red wire which goes to +12 volts power source. Pin 6 is the black wire and goes to ground of the power source.
The other harness is credit output. Part # 0030738 Interface Harness Assembly can be ordered from any Rowe distributor's parts department. It connects to connector P8 on the bill acceptor's control board. Pin 5 is the one dollar credit positive pulse. Pin 6 is the one dollar credit negative pulse. Pin 7 is the five dollar credit positive pulse. Pin 8 is the five dollar credit negative pulse.
These credit pulses are output from an open collector opto-isolator chip. Credit positive pulse is from the collector of the opto-isolator. Credit negative pulse is from the emitter of the opto-isolator.
Dip switch settings for the various applications are shown in the interface instruction manual.
