(A momentary short circuit on Con 12 on coin-op models evokes a "permission to start"
request via the CBT serial data link. A connected payment device (such as a card reader) then
has the responsibility to allow or deny the start request. This eliminates the need to press the
Compass Control knob following payment and allows the machine to start immediately if the
loading door is closed when payment is made.
