9. Dual Coin Entry Rundown Interface (DCE)
Figure 5: DCE Connector Pin Outs
This interface is used with the dual coin rundown. It is used to provide information to the SR5i
indicating whether a coin or a token has been entered.
Normally, when there is no coin or token in the entry, both the opto detectors are active as they
are receiving infrared light from the corresponding emitter. This is the quiescent state.
When a coin or token is entered then the light path between the corresponding emitter and
detector is broken and the detector becomes inactive.
Once the coin has passed the optics, the system returns to its quiescent state.
