6.2.5 MC-62 Comparator Connector Pinouts
The connector J1 on the right of the comparator PCBA connects to P14 on the

The coin interface section of the I/O Driver Board receives the signals from the coin
comparator and solenoid optics and converts them into the form required by the Main
Board. For a description of the coin-handling interface refer to the I/O Driver Board
chapter.
The signals to and from the coin comparator are shown in the following table.
