r17537 Tuesday 28th August, 2012 at 16:00:57 UTC by Jim Stolis
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]

576584        Emulating IGT IDO22 Pulse Protocol (IGT Smoke 2.2)
577        ID022 protocol requires a 20ms on/off pulse x times for denomination followed by a 50ms stop pulse.
578        The DBV then waits for at least 3 toggling (ACK) pulses of alternating 20ms each from the game.
579        If no toggling received within 200ms, the bill was rejected by the game (e.g. Max Credits reached).
580        Once toggling received, the DBV stacks the bill and sends two 10ms stacked pulses separated by a 10ms pause.

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