Title: version eprom crc error 0xF002 Post by: rjpohl on December 06, 2008, 11:06:28 PM I started getting "CALL ATTENDANT" error code. When I open the door I get the "system error" followed by "version eprom crc error 0xF002" error, after clearing all errors with jackpot key I'm prompted to close main door. As soon as door is closed "Initializing" flashes on screen for a split second and then "CALL ATTENDANT"
I performed a complete ramclear and the it worked properly until it set idle for about an hour with power on. I believe the problem started right after the "attract" noise was played. Any suggestions appreciated. Title: Re: version eprom crc error 0xF002 Post by: Foster on December 07, 2008, 02:55:01 AM Check the power supply behind the reels.
Re-seat the power supply. Title: Re: version eprom crc error 0xF002 Post by: Slotmaster on December 07, 2008, 11:49:52 AM Replace the Version EPROM (VSXxxxxx) on the MPU board. First try to re-seat it
Or you can fiddle around with the power supply but if that fixes it I will buy Foster Lunch (via paypal). Title: Re: version eprom crc error 0xF002 Post by: rjpohl on December 07, 2008, 12:51:24 PM Slotmaster, I think you were right, I removed the chip and then reseated it, everything seems OK for now. I'll leave it on for a few hours and see what happens.
What does the Version chip control? thanks, Bob Title: Re: version eprom crc error 0xF002 Post by: Foster on December 07, 2008, 12:59:19 PM Denominations that are available, jurisdictional settings, money/currency symbols.
Title: Re: version eprom crc error 0xF002 Post by: Slotmaster on December 07, 2008, 01:01:21 PM From what we care about it controls the Multi-denom capability (Split Screen which many call it). If you use the one with the SD you get the scrolling credit screen, if you use the MD version of it you get the split screen with the $.
Really it's the chip that tells the machine which state it's being used in and the limits associated (Including MD or SD) as foster points out. Title: Re: version eprom crc error 0xF002 Post by: rjpohl on December 07, 2008, 01:25:58 PM thanks and Karma to Foster and Slotmaster.
Does any one have a list of Version chips and documentation Title: Re: version eprom crc error 0xF002 Post by: Slotmaster on December 07, 2008, 01:30:14 PM From a PSR
Version PROM The version PROM controls what is available to meet special jurisdictional requirements and controls what certain features and options are available. The label indicates STEPPER VERSION and the version number: VERSION DESCRIPTION VS011CX0 single denomination –Colorado ONLY VS011CX1 multi-denomination –Colorado ONLY VS011GX0 single denomination VS011GX1 multi-denomination VS011GX2 multi-denomination with denomination-plus mode VS011GX3 multi-denomination with fractional-cent VS011IH0 single denomination –Netherlands ONLY VS011IH1 multi-denomination –Netherlands ONLY VS011IX0 single denomination –International VS011IX1 multi-denomination –International VS011NX4 single denomination –New Jersey ONLY VS011NX5 multi-denomination –New Jersey ONLY Title: Re: version eprom crc error 0xF002 Post by: knagl on December 07, 2008, 03:14:11 PM Computer geekery here -- warning, warning! :96-
CRC stands for "cyclic redundancy check". It's an error checking method and essentially compares a checksum that the chip should have versus what is being read -- more or less the same deal with looking at a checksum when you burn an EPROM. The machine was saying that the CRC failed -- it was having trouble reading or getting the accurate information from the chip. The causes of that could be a corrupted chip, or a chip that isn't quite seated properly. In your case it was the latter, and as you observed the issue didn't happen until it tried to play an attract sound -- likely the part that wasn't making a good connection was related to that, or needed to access that part of the chip. |
