Hello. Recently upgraded my IGT PE+ with new program chip supporting multi-game wingboard. My BV unit is a DBV 145 SH with ID 011 program chips which worked fine until wingboard upgrade, now validator enables but does not accept bills. Convinced it a protocol issue requiring ID 022/023 software. Problem is I can't find either (1) a new EPROM with latest version of DBV 145 SH ID 022/023 (would need both chips since not sure of protocol required) or (2) a new DBV 200 SH validator head with ID 022/023 software. Can anyone advise? I've searched this entire site but find only rare references to IGT PE+ machines running DBV 145 or 200 SH heads. Seems most posts are referring to SS head which supports a different transport mechanism (vertical not horizontal).
