So a possible fix!
The sale approved issue finally came to a head and decided to sale approve every single
transaction the Wednesday before last, it would also do something new and beep the same amount of times as the wash price, immediately after selecting the wash I was trying to fire. (example: 16 beeps for my $16 wash) My distributor contacted Cryptopay for the 1000th time, and they literally had no idea what was going on. On a whim, Cryptopay told us to move the red and green wire from pin 6 to pin 5 (one
coin pulse input to the other
coin pulse input) and magically we haven't had one sale approved message in a week and a half. If you are struggling with this same issue let me know and I can take pictures of exactly what we did.
I don't want to jinx it by saying its fixed, but this is the longest that it hasn't had a sale approved message in a very very long time.
