Hi all,

As I have just bought a c435 coinmech on eBay for a couple of quid for my Barcrest Royal Jewels fruit machine I am wondering whether it needs a parallel interface cable between the mpu4 unit and the c435 or is the routing plug enough as it is? If you miss the parallel interface cable can you get one from a dealer and is this a fairly standard item or is there a difference in cable pin layout per game?

Thanks,

Richard

you need to have the parrallel lead connected between the mpu and the coin mech.

it should be a standard cable if it has already worked in an mpu4 barcrest machine but i do not know if there is a difference between the wiring of a loom that is designed for the uk market and the euro market.

i would assume they are the same.

Thanks Baz, I will receive a cable shortly from another forum member who kindly sent me the cable yesterday, so I will have a go with that if I don't have a cable fitted in my machine already

[Rich69]

I got the c435 coinmech in yesterday and it fits in the holder, so far so good, and I still have the parallel cable from the mpu4 that was still tucked away somewhere in the back. Now my parallel interface cable ends in two plugs: the parallel interface plug (15 pins) and a sorter override plug. When I look at the parallel interface pins on the c435 I have 21 pins in total: 4 pins, one blank and another 16 pins. However my plug only has 15 holes...how should I fit that onthere; just skip the first pin of the row of 16 pins, or should I start counting at the four pins and the blank and then the 16 pins? I have attached some pics to clarify

miss out 1 pin at the top and plug in so the blanked out socket on the cable lines up with the blank space on the mech.
you should only have 1 pin at the top showing.

Thanks Baz, the red wire is on the plug is to power up the coinmech isn't it?

[Rich69]

Whoops think I'm wrong, the red one is ground and the brown wire is +12V

[skabaz]

i would have to find a mpu4 manual with the wiring to confirm that.

I've looked at the wiring diagram and the mpu4 fse manual but could not find any color codes for the wiring, but I found an Excalibur manual which is I believe an mpu4 barcrest in a genesis cabinet, and inthere I found the sorter override layout connected to a C435: Pin 1 is red, Pin 2 is Key Wire, Pin 7 blue, Pin 9 is white/brown and Pin 10 is brown. Comparing that to the C435 manual, the sorter override layout states Pin 1 is Ground and Pin 10 is +V Supply.

Furthermore the mpu4 fse manual shows that the +V Supply wire from mpu4 to coinmech has a 3A fuse in between; I have seen that one in my cabinet and the wire's definately not red..

Does that make sense?

[skabaz]

this could be difficult!!!

have you tried the original loom that was hidden away inside the machine??

rich69, I found some info that may be of interest, check these out for pin information http://slot-techs.co.../backissues.htm
look in july 02 page 10 plumbers guide.
and www.coin.demon.co.uk/parts/c00084.htm
hope these help.

Dave.

Thanks Baz & Captain, these articles confirmed what I was thinking, but I will doublecheck to confirm, I will be using the original loom that's in the machine (see pics posted previously) connected as Baz pointed out earlier in this thread and the image below I found on the web confirms Baz' recommendation (the image text is in German but not too difficult to figure out)

The German Barcrest distributor was so kind to send me a German MPU4 manual and a German Royal Jewels Owners manual, and there one of the images shows the parallel interface layout to a C435 (as that's the standard coinmech for this machine) including wire colouring

Haven't hooked up the coinmech yet; too busy doing other stuff last week....what's the normal position for the Rotary Switch on the coinmech: No Tokens or one of the Token Groups. My C435 coinmech was reprogrammed to accept 0,50 cents, 1 and 2 euro coins.

Channel 3 is set to accept to take 2 Euro coins,
Channel 2 is set to accept to take 1 Euro coins,
Channel 1 is set to accept to take 50 cent coins.

I'd say the rotary switch should be set to Position 0: No tokens.

Now my next question is; what if I want to get the coinmech to accept tokens as well; I just move the Rotary switch to one of the preprogrammed token groups? And will it still accept Euro-coins in that case or will they get rejected?

Okay, Í've put the coinmech in; and discovered the following. The rotary switch on the coinmech is set to C (accept taught tokens). That was the setting it was on when I got it, and I haven't played around changing the setting yet.
It now accepts 2 Euro coins and gives 50 points for that; it also accepts 1 Euro coins and rewards 20 points for that. It doesn't accept 50 Eurocent coins, but I can live with that. What surprises me is that the coins fall straight through into the cabinet money collecting drawers at the bottom. I would expect them to fall into the hopper first. Secondly, the Payout button on the cabinet is not lit any longer; is that because the hopper is empty? The Payout-button is lit when playing in Test Mode.

i am not sure of the settings for euros and cents as i only deal with uk currency and have never had to deal with anything else.

also the european machines may well be a different set up to the uk machines.

when you turn the refill key what does the hopper reading say???

if it reads that it is full then that is why the payout light may be unlit and also the coins going straight into the cashboxes and not the hopper.

[Rich69]

Thanks Baz,

As far as the coins are concerned, then I am quite happy with the fact that it takes 1 Euro coins and 2 Euro coins and won't bother with the 50 cent coins then. I would assume that the Payout light would be lit when the hopper is full; as the hopper contains enough coins to pay out wins? But am still learning, and sofar I haven't blown any fuses or anything so I am not complaining yet :-) I will have a go at the Refill Key suggestion tonight and add some coins into the hopper to see whether the machine actually pays out...the refill key is what you use to fill the hopper with coins, or am I missing things completely?

[skabaz]

the easiest way to do this is the following...

open the machine so you can see the hopper and put whatever coins that are supposed to into the hopper(i would assume its 1 euro coins).
just put at least 10 or 20 euros in the hopper.

then open the door where the cash boxes are at the bottom and there should be a switch called the hopper dump button.

turn the refill key and then press the hopper dump switch,it should then say something on the display in regards to which button to press to dump the hopper(probably will be the start button).

the machine should then payout all the coins you put into the hopper and the machine will now know how many there are.
put the coins directly back into the hopper close all the doors.

when you play the machine the 1 euro coin should now go into the hopper and not the cashbox.

That sounds promising Baz, I'll give that a try later on today; thanks!
