Thank you my friend. I don't know anything about electronics and I've been trying to install this in an arcade for 3 years. And this is because a "Brazilian guy" explains it all in an impressively complicated way (it never worked that way). As explained here, it's simple and... IT WORKS. Thank you very much.

Thank you. Just picked up two of these units off Amazon. I had no clue how to setup with Retropie. Awesome video.

The reason there was a grey wire commoned with the positive was for the total coin counter function. The other grey counter wire pulls down to the negative rail via a transistor to click round a mechanical counter connected between the two grey wires. It's a function that is included for professional gaming machines where there is a requirement to keep a permanent log of coins for duty/accounting purposes. The pulse output is for the logic board, Arduino or MAME interface.

I dug through a lot of videos on KZread before it served this one up. Your video was BY FAR the most useful. Thank you!

Thank you for your video.

you my friend just saved me a ton of headaches! gotta love the Chinese to English manual instructions NUMBERICAL???? HAHAHA! also one minor thing I noticed was that you don't want to have the multi-meter leads connected to the counter and coin wires when you are sampling the coins. Doing so caused me to get "0" on the counts and then I would need to power off the unit and redo the procedure. Leaving the multimeter disconnected until it was programmed solved this issue for me. Hope this helps someone else out, Thanks for the video!

An excellent tutorial, mate. I never thought I'd get my head around it but you made it nice and simple. My Game Elf cabinet is now accepting coins. Thank you so much!

You sir...rock... it took all of 3 minutes watching your video. If I had to do it with the instructions that were shipped, I'd have canned the unit.

Very informative. First real video I've found on how to set this up. Thank you!

Thank you so much for this. I have been trying to find this info for such a long time

Thanks for this vid dude, got that exact model of coin acceptor coming in the post..!

Thank you so much for this, incredibly helpful, building an arcade cabinet with my son.

hello, have you noticed that this coin acceptor kills some USB boards? Mine sometimes work and than not. Der ist some Current on the Acceptor wires and different current on the USB Board. One board went dead with ghost inputs on the other all buttons besides the ones i plugged in are not responding anymore. In all i tried the Acceptor.

Thank you so much. I have a somewhat different model (accepts six different coins, no need to switch off after initial setup / before sampling), but without you would have had no idea, where to connect my USB-Joystick-Adapter or program this thing!

Thanks a lot! It's better than trying to understand the bad chinese translation to english photocopy I got with my mech!!!

Really Great video (much better than mine) I will point to yours for further info in my old one. I never knew how to set up multiple different coins, until now I only could use 50p for one pulse, now I have £1 for two pulses. Cheers

Wonderful video! Detailed and well explained. Thanks a lot!

Thanks for this video, after seeing how it’s done I def want to add one myself 👍

Hi Eldon! Thanks for the clear instruction! I had no clue without this and only the manual. The only problem I hav is that I tried plastic coins that we would like to use but are not registered by the meter. Do you have a suggestion? Which coins could be used?

THANK YOU!!! awesome Link as well! You are my HERO!!♡♡♡
