Here’s what happened. I ordered the serial instead of the standard and it does not accept cryptopay. I can send it in and have it converted.
I am a Dixmor led7 fan ... but out of curiosity ... can someone explain why anyone would order the serial version?
Just wondering how common is that serial firmware actually used in the real Dixmor & other
coin payment methods world. Cryptopay has gone in the direction of the the laundromat industry is one of the reasons I am asking. On the SparkFun
coin mechs that we have been testing for the future retrofit on our 32 washing machines ... we have found that our ability to do via laptop "in house" changing of the specific "Arduino Ide based" firmware had
advantages with serial communication vs just the pulse communication.
