ACW-4 retrofit for Nayax

[Clean Days]

I am changing my ACW-4 from CryptoPay to Nayax. I installed the Nayax retrofit kit that I bought from CWS ( Steve has been great). Although we are struggling to get it to work. My current ACW was retrofitted for the CryptoPay and we are thinking that is the problem on why the Nayax retrofit won’t work. Does anyone understand what the CryptoPay retrofit does to the ACW circuit board that may cause and issue with changing it to the Nayax system? I know the CryptoPay retrofit instructions talk’s about cutting a component off of Q10 and discarding it. Is there anyway of getting this component to put back on my circuit board or is there any circuit boards out there that has not been retrofitted, and I could trade for mine that is retrofitted for CryptoPay?

When you install Cryptopay on a ACW-4/5 controller you cut off the 5 volt regulator from the board and install a jumper around around it. I have a unmodified ACW-4/5 controller.

Do you think that the regulator has to do with the new display that is installed with the CryptoPay retrofit?

By removing the regulator it increases to voltage to the display. The Red Cyrytopay display also has a library of words built into it that could be confusing the Nayax reader.

Have you talked to Steve about your issue? Also, what exactly is the nayax system doing that you are having issues with. We have his kit on an acw 4 and another on an acw 5, both work, though we do get the occasional hiccup with the nayax system

Steve and I have talked several times about it and he has been great.

Steve and I have talked several times about it and he has been great, we just havn't solved this problem yet. Were your acw4 and acw5 previously retrofitted for CryptoPay before retrofitting them for Nayax? I am thinking that is my problem because mine was.
On my new circuit board for the Nayax retrofit it has LED's for TK & .25 that stay lit all of the time. Steve doesn't know why they are; they shouldn't stay on all of the time. The Nayax takes and approves the credit card when tried but it does not tell my Hamilton controller that it received payment, so it won't start the wash.

Cryptopay sends a "payment made" signal via the token wire that goes to the controller. Stated another way, when the card is verified and sale approved, CP tells the Hamilton via several pulses to the token input. It would be identical to inserting two brass tokens, and the token acceptor sending pulses to the token input, completing the payment and saying OK to the vend.

It looks like the CP has a red with green strip wire coming off of the card swiper and ties into the pink wire coming out of the ACW-4 controller. That pink wire goes into the controller one way and up to the blue wire on my slugbuster the other. The new Nayax retrofit ties onto that same pink wire and takes it down to the new Nayax circuit board. So, it should be doing the same thing as far as sending a token input signal. I am not sure when the pink wire goes into the ACW-4 controller, if something was changed in there when it was retrofitted for the CP system. Randy thinks that the CP display may be confusing the Nayax system but I am not sure. I am not sure if the display is the problem or not.

I never had cryptopay, just went from hamilton system to Steve's system. I would try to get your hands on some stock parts and see if it works.

I found a used ACW-4 that has not been retrofitted for CryptoPay and I just installed it but I had the same problem. So I have shipped the control board that Steve provided back to him so he can test it to see if that might be the problem. My hope is that he finds a problem with his board and replaces it and that fixes my problem.
