Q. How do I connect a C220B coin mech/coin accepter to the Coin-kit board?
A. Coin kit is not designed for use with a c220b, however u can modify CoinKit at your own risk
put coin kit into ccTalk mode - see here
http://jukeblaster.com/forum/index.php?topic=459.0on the ccTalk connector of ur c220b conect the following-
connect the data pin of the c220b to the coin screwterminal on coin kit
conect the 0v of the c220b to the gnd screwterminal on coinkit
connect 12v pin of c220b to 12v screwterminal on coin kit
u may also need to connect pin9 to gnd (ccTalk enable) read the c220b datasheet, (google it)
put 12v into coinkit 12v jack, see if 220b takes a coin, if it does plug in the usb
