JVL Retro ioboard connections?
« on: September 05, 2016, 06:46:18 pm »
Just acquired some jvl retros in about a thousand pieces and I'm trying to reconstruct them. Can't seem to find manuals anywhere. Looking to figure out how the io board connects to the motherboard. There appears to be a 7x2 pin connector that I can't figure out where to plug in.

Also, anyone know where I can find cheap aftermarket power supplies?  And the back doors for these?

I believe the larger connector to be the plug for the DBA, the 2x7 is what I'm stumped on

yes, the smaller is meant to be plugged into a 10 pin electronic coin mech (standard mars/coinco/cctalk type pinout.) with 2 pins hanging on either side of the connector. (the extra length was supposed to keep it from getting pulled sideways and pulled out.)


1 Gnd
2 +12vdc
3 coin 5
4 coin 6
5 N/C or Coin Counter
6 Inhibit acceptance
7 coin 1
8 coin 2
9 coin 3
10 coin 4

in canada it has a non standard signalling.

Coin 25 cents - Line 1
Coin 1 dollar - Line 2
Coin 2 dollar - Line 1+2 simultaneously

the larger is indeed for a BA. (in canada we never used bill acceptors in these machines.)

Those coin acceptors aren't cctalk. They simply pull a line to GND for 100ms if the correct coin passes.
(The newer ones can have a cctalk output as well, but that's on another connector.)

I was describing the connector as being that style as opposed to the cashflow style of connector  (16 pin connector) or other custom connector...since it appears at first glance to be a non standard connector.

the CCtalk connector itself is a 4 pin connector.  I should have said cctalk COMPLIANT mechanism, since all these would also have a standard 10 pin connector.

90% of all coin accepters on the market today are of the 10 pin header style.
to clear the air cctalk is a protocol used by 99% of mfgs to "chat" with the coin accepter in question

just to give u an idea of what shawn was talking about
here is a rm5 pdf
please note
the pin headers
1-10 pin
1=14 pin (old style)
1--6 pin (programmer interface >handheld< cctalk version)
and of course there dip switch's

A lot of the somewhat older coin acceptors have the 10 pins connector but no cctalk connector.
That's why I made the correction.
Some brands offfer the choice to have either cctalk or a parallel output.

cctalk is suposed to be the successor of the parallel output. The idea is that you can have multiple devices on the same serial bus. It makes cabling less complicated. It's being in use on gambling machines. It's not yet popular on amusement machines.
And, as you said, it can be used to program the coin acceptor, but I doubt there is a standard for that?

It's kind of confusing to see a 14 pins connector on a 10 pins header. It might help against misalignment, but some coin acceptors probably won't accept the plug due to the hole in the housing being 2 small.

But... It's getting of topic. (This is not Wikipedia after all.)

standard, yes... but also no, proprietary.

The cctalk protocol is standard across all cctalk compatible devices (same bits mean the same thing) but the software to program them is locked down like a nazi concentration camp... often having a licence good for X number of acceptor programs or for X number of days before it disables itself.

u can always tell a cctalk style coin acceptor
just look for the 6pin header..
if it has 10 pin or 14-16 headers it is only to allow for different mfgs hook ups
an ideal acceptor for this is the cash code 330
it has on the older units a 14-15 pin header serial in design
the newer cash code 330 has a 10pin header for the serial out
both units still have the 6 pin header for programming
