Hey peeps looking to build a MFME cab, done a few MAME cabs, and I can get MFME to read the keystrokes, my question is how do you guys make the program connect to the hopper and payout?

 

sorry if it's a noob question, but I'm starting to build a prototype and would very much appreciate your help

MFME can connect to the hopper via an I-PAC ( https://www.ultimarc.com/ipac1.html) and a Pac-Drive ( https://www.ultimarc.com/pacdrive.html ) with outputs off at startup - ensure that you request that option.

 

Note that you must not have conflict Pac-Drive's as they have different numbers.

 

Both of these devices need to share a common ground and can be wired up to a ME126 coin mech ( eBay ) and a couple of Universal MK IV parallel hoppers ( http://www.e-service...per-replacement) along with the baseplates ( http://www.e-service...opper-baseplate ), one for each hopper.  The hoppers need to run off a seperate 24v PSU (eBay), but this kind of thing ( https://www.ebay.co....K-/291087849273 ).

Do note tho, that any hopper can be used that has a low going signal to enable the motor and gives a low going pulse for every coin payed out.

 

Once this is in play and everything correctly wired and configured - you can control the hoppers via MFME.

Note you must be running MFME v6.

Hi Reg,

 

I want to say You make a great job !!!

 

I have connect my hopper to my pac drive and when  i push the collect button,  all the tokens in my hopper  falls.

this is a good first step but  how do you configure the token countdown ?

 

the hopper sensor out must be connect to  i-pac for deduct each token or is different ?

 

thank for your answer

The Hopper coin sense output connects to the i-Pac which must generate a '[' for hopper 1 and a ']' for hopper 2

Wizard,

Thank you for making us dream with Mmfe.

 

all it's ok now

Glad you got it sorted

By the way, do NOT power your hopper motor directly from the PAC Drive as that will overload it and likely kill it. If you need to do this use a PNP power transistor between the PAC Drive and the motor and add a back EMF diode as shown in some of the hopper datasheets.

 

If your hopper has a logic level motor enable then you can connect it directly.

i have connect the output of  the pac drive to a ssr relay and the ssr control  the hopper whith is power supply

[Wizard]

Excellent

Hi wizard,

the epoch roms are good with my hopper  (i select hopper 1 in my pac drive output) but i can't found how parameter  the mpu4 roms (ex: criss cross crazy). i have try to change the dip switch and the payout column but nothing happens. Have you the solution ?

thank

Eric

[eric]

ok i have found i must select the hopper number 7

Oh no! I wish I had seen this earlier. I only ordered the pacdrive. I thought the opto sensor just plugged in to the pacdrive. Obviously I can get my hopper to spit coins out, but it doesn't count what's coming out.

 

Does the hopper need the opto sensor to be plugged in, to work with old triac payout stuff? 

 

BTW if anyone is selling an old I-pac let me know.

Answered myself this by testing. Yes it works (pulses my relay to spin the hopper), but not accurately of course.

 

BTW. Does anyone have a diagram of the opto sensor (hopper) set up? Mine has 3 wires. [+5v]  [Gnd]  [Output]. Which one goes in to the Ipac, and which ones Pacdrive? I am trying to work out why I need to spend $55 just to get the opto sensor working.

hey sorry to bother you but, can you please elaborate on this a bit more. I have bought two pacdrives and would like to understand before I hook everything up. Thanks for your help

Pac Drives are only output drivers, coin sense is an input which you connect to an IPAC, it can go to any of the inputs but the IPAC needs to be programmed to generate a '[' keystroke for hopper 1 opto and a ']' for hopper 2 opto

Just to clarify things, MFME drives an PAC Drive output low to enable the hopper motor, and expects coin output signals from the hopper to appear as keystrokes from an IPAC, each key decrements the payout count and when it reaches 0 ( or times out if the hopper is empty), it deactivates the hopper motor.

 

Hoppers can be directly connected to the PAC drive if they have a logic level motor input and the supply is permanently connected. If the hopper doesn't have a logic level motor input the PAC drive output must be connected to either a relay or transistor driver to drive the motor.

 

Hopper coin outputs usually pulse low when a coin is output and this can be directly connected to an IPAC input. IPAC is also used to connect all your cabinet switches

Thanks wizard, very clear now.
