Need help with IGT I+ Bill validator problems

[ucanwin]

I have two IGT, what I believe to be I+ upright machines, a Kenny Rogers game and a Hexbreaker game. The bill validator on the Kenny Rogers was working fine......until I messed with it. I recently got the Hexbreaker machine, and have had problems with the bill acceptor since I got it. It comes up with a Bill Validator Error message or, at the moment....Bill Validator COMM FAILURE. At times, I would put the cash can in and it would clear the error. When the machine would accept the bills and I would shut it down and the next time I would power it up.....the error would return. Now I have the Bill Validator COMM Failure. So......dummy me....I decided to take that the bill acceptor assembly and try it in my Kenny Rogers machine to try to see if it was the problem and maybe it would work in that machine. That was not the thing to do, as I soon found out. The Kenny Rogers machine which was working fine, came up with Bill Validator CRC MISMATCH. so, I put what was, the good working bill acceptor back in the Kenny Rogers machine and now....it also has the Bill Validator CRC MISMATCH error. What did I screw up, and how can I get both machines to accept bills? PLEASE HELP!! Thanks. Also..... what is a CRC Mismatch.....and is COMM Failure....communication failure?

New update on my problems..... I have the two machine powered up and the Kenny Rogers machine that had the Bill Validator CRC Mismatch error message somehow, on it's own, corrected itself and is now showing no errors and is accepting bills again. So....I still need help with the Bill Validator COMM Failure on the Hexbreaker machine. Anyone???

I had the same problem when i changed bill acceptor on my GK.I found that if you go into menu using small white button with no credits i was able to reset the ccr or crc what ever it is.Worked like a dream.I guess the bill acceptor sets up its own little program and does not like to be moved to another machine.If you have trouble getting into setup i may be able to help.I am using a 3902 board.

Jerry No big deal switching BV from one machine to another, 9 times out of 10 you will not get the CRC error.This time you did and now your going to learn something so the day isn't going to be lost

Open the main door and press the test button on the MPU, screen will change, touch set up, touch machine options, touch Peripheral Device Set up.  Your top left the center tab is Cal BV CRC touch that tab, the machine will do it's thing and your done, close door and test with a bill. For what it's worth this can be done with credits on the machine. Now not all I Game soft ware will have Peripheral Device Set up. ( I looked at my Kenny Rogers and it did ) If you don't see that in Machine options just touch each and every tab until you see something about CRC. Trust me you will do NO harm in anyway by touching all these tabs and looking around, matter of fact I recommend everyone takes a look and see what they have.

Ed To ans, your question you sent in a PM,  If your talking about the board I set up for you, all the games are already set for Max pay, If were talking about a different board, your going to have to use your Key  chip. In Key menu go into Machine Options, touch Game Selection, a page will come up with a whole lot of Red tabs and one Yellow tab. If the Yellow is at the top the machine is already set for Max pay out, if the Yellow is down a ways, touch the Yellow and it will change to Red, now touch the top Red tab and it will turn Yellow, touch Save and close the door your done.

Thanks, Buzz and Grumpy, It seems to have solved my problem. I also was able to get my game percentages changed. The machine was set to rip anybody that played it. All three denominations were set as low as possible. The game wasn't much fun to play as it was.
