Title: Can't connect Coin Slot to 2 player Xin mo not working
Post by: bradley1023 on May 24, 2014, 03:50:45 am
Hello all

I am now up to mapping buttons on my Cocktail Arcade Project, and i have bought one of those cheap Comparative Electronic Coin Selectors for a coin slot and i want to connect it to the xin mo as a button input. Shorting the two wires i programmed for the coin slot inserts a coin, but when i connect it to the coin slot itself it doesn't work? i have applied 12v to the coin slot and it accepts the correct coins.

I tried connecting ground on the coin slot to ground of the xin mo and the coin signal to the button 10 input on the xin mo which as i said is programed to coin insert with no luck. I found this picture someplace and tried this configuration with a zenner diode to take down the 12V but it also didn't work.

Thankyou in advance, any other questions you might have or if you you want a photo of something i am happy to supply it.

InfantSorrow ran into the same thing in this thread (http://forum.arcadecontrols.com/index.php/topic,137899.msg1423848).

The Xin-Mo ZD encoder is an active high device -- the common trace around the outside edge has 5v on it, instead of ground.

He ended up having to use a small relay.

Part #s and wiring diagrams are in the other thread.

if you you want a photo of something i am happy to supply it.
If you haven't installed your coin recognizer yet, would you mind taking several good pictures of it for the Wiki Coin Doors (http://newwiki.arcadecontrols.com/index.php?title=Coin_Doors) page since it's a pain to contact vendors asking to upload the *copyrighted* photos from their site for the Wiki -- much easier when someone takes and donates photos of one that isn't installed yet.   :cheers:

If you (or anyone else) can take several pics just like these (same angle and distance, clean/contrasting background), it would be greatly appreciated.

EDIT: Mixed up the Xin-Mo with the ZD Encoder -- must have been really tired when I posted that.   :embarassed:

Wire a Xin-Mo same as an IPac.

Hello PL1
Thanks for the response, i attempted hooking it up again with a different zenner diode and played with the speed switch and sensitivity pot and i got it working 100% flawlessly. As for taking some photos, i had a go below, what do you think? its not the best i know it doesn't look as bad as a smaller image though  ;D

Here is another view of it side on like the other one you had as an example.

Thank you, sir.   :woot

Those photos are perfect.

What part# zener diode ended up working and can you do a quick wring diagram of exactly how everything is connected?
(for the next guy trying to do this)

EDIT:  Error made in earlier post -- please disregard diagram request.

That's great i am glad i could help  :cheers:

I ended up placing the diode the same way as the diagram i attached in my first post, And its was simply in my draw of parts i have soldered off things, i believe it is marked 12 C3. I hope the next guy will find it this easy too, because i read through the other forum PL1 where you helped InfantSorrow with something very similar and it looks like he went to a lot of trouble in putting in a relay.

D'oh. Just realized that you're using a Xin-Mo which is active-low device like an IPac, and not an active-high device like the ZD encoder that InfantSorrow used -- that's why he needed the relay. :embarassed:

Found two 12c3 zener diode datsheets -- they are 14v diodes instead of 5v diodes.   :o

You may be damaging your encoder by using that diode.   :dunno

A "5c1" might be a better choice. (datasheet for General Semiconductor/"GZ" Zener diodes here (http://www.digchip.com/datasheets/download_datasheet.php?id=357230&part-number=GZ12C3&show=inline))
