Added IGT ID-023 Protocol to driver. This additional DBV protocol allows all remaining unsupported sets to accept dollar bills in-game. The protocol is switchable via driver configuration (along with denomination). [Jim Stolis]

Emulating IGT IDO22 Pulse Protocol (IGT Smoke 2.2)
|
||||
ID022 protocol requires a 20ms on/off pulse x times for denomination followed by a 50ms stop pulse.
|
||||
The DBV then waits for at least 3 toggling (ACK) pulses of alternating 20ms each from the game.
|
||||
If no toggling received within 200ms, the bill was rejected by the game (e.g. Max Credits reached).
|
||||
Once toggling received, the DBV stacks the bill and sends two 10ms stacked pulses separated by a 10ms pause.

PE+ bill validators have a dip switch setting to switch between ID-022 and ID-023 protocols.
|
||||
Emulating IGT IDO23 Pulse Protocol (IGT 2.5)
|
||||
ID023 protocol requires a start pulse of 50ms ON followed by a 20ms pause. Next a 15-bit data stream
|
||||
is sent based on the country code and denomination (see table below). And finally a 90ms stop pulse.
|
||||
There is then a 200ms pause and the entire sequence is transmitted again two more times.
|
||||
The DBV then waits for the toggling much like the ID-022 protocol above, however ends with two 10ms
|
||||
stack pulses instead of one.
