SOLVED?: S2000 Hopper I/O Test “Coin Jam” on Known Working Hopper

[DB26]

Solved...maybe? More info in new post.


Hello everyone.

I was testing a known good hopper on an S2000 and during the I/O test, all it says is “Coin Jam” That same hopper works well on another machine. I swapped in a second hopper and got the same message. Any idea what to check first?

I have coinless disabled, hopper limit is above 0 (forget what amount), and split pay is enabled.

I have only done the I/O test so far. The hopper does not act like it tries to move or anything. Also, the hopper level is reading 0 even when I have the “full” probe grounded. Seems like the hopper is not being sensed by the machine. For a control test, I turned the machine on without any hopper installed and it gave me the same “coin jam” error on the I/O test. Maybe something up with the harness? Which connector controls the hopper?

Also I have a TITO@Home installed.

I was reading around the forums and saw maybe using “Auto Configure Netplex Devices” might help? I’m going to do some troubleshooting when I get home. Would the machine need a key chip? I already had coinless mode disabled from my previous key chip. Was not using a hopper up until I tried last night. So it has not been keyed in a few months.

[DB26]

Well. After hours of troubleshooting I have gotten nowhere. I have tried swapping MPUs. I have cleared and keyed, disabled the TITO, unplugged and checked all my harness wires, swapped hoppers and got nada.

Here is the message I keep getting:

Error 404 (Not Found)!!1

The machine accepts coin. It just won’t see the hopper.

I don't see that you have tried replacing the cabinet I/O card. It runs the hopper. They fail often.

[DB26]

Thanks for the reply. Actually I forgot to put that down. I swapped in the I/O card from the machine with the working hopper. Still did not work. I put the card and hopper back into their original machine and they still work fine.

I tested the hopper plug with my multi meter and I have 13 volts coming through.

[DB26]

Let me also add that I recently installed a new main cabinet harness into the machine. Part number 62300800.
Everything else continues to work fine.

I upgraded the harness because I needed to hack some connectors and decided to install the new one and hack the old one. I noticed the new harness has some new extra connectors, like “netplex input” could any of these need to be jumpered or plugged in somewhere?

I noticed on my working machine, something is plugged into the spare senet, but I do not know what. The working machine is a 3 reel + skinny bonus reel.


EDIT: As some of you may know, this machine is now capable of running both the 50x and 1270 MPU boards. So I transferred my chips to a 1270 and gave it a test. Same error. So I do not think it’s the MPUs. Gotta be something in the harness or an I/O card right? I guess I will try swapping I/O cards again.

EDIT 2: I just disconnected to molex connector that attaches from the backlit reel controller to the cabinet I/O card. It did not cause any errors. I then pulled the card itself and I got a meter disconnected error. Does the molex have a major effect on what the I/O card will do? Because it did not make a lick of difference for me.

[DB26]

Well, I have given up for now.  Happy 4th everyone.

Robert give me a call tomorrow or later in the week.

I’ll call you this week, Tony. Thanks

Reel backlight driver is not beeded so you will not get an error with it unplugged. It sounds like senet is working properly if your buttons are working. You can confirm senet is not the issue by by running a reel light test. If that works my bet would be damage to the harness running from the cabinet io card to the hopper.

Yes, I am starting to suspect that as well. I will do a few more tests, but I am going to try to exchange my harness for another.

Solved it everyone. It was due to my ignorance.

I put a new harness in and decided to do continuity checks on all the hopper plug wires. Well, after tracing all the wires I discovered that half of the hopper plug wires go back into a plug that I never installed. Turns out it goes into J7 (spare senet) I never installed it because I did not realize you could plug a 10 pin molex (On the harness) into a 12 pin molex (on the backplane) But I remember being told the hopper is a senet device, so I figured what the hell. I plugged the 10 pin molex into the 12 pin backplane spare senet and BAM. Working hopper. Thanks for your help everyone.

There should not be a miss match in the pin count of plug and socket.

[DB26]

I’ll take a picture. The setup is working, though.

[DB26]

I do not have access to the machine right now but I can show you on a photo of the harness.

I have circled in yellow the molex connections that go directly to the hopper plug. Those are the ones that I confirmed in my continuity test. And that molex was one of the molexes I had unplugged, once plugged into the spare senet the hopper worked.

Where else would that plug into? I have no more open 10 pin molexes on the backplane.

Am I missing some sort of adapter?

According to the wiring diagram its a netplex plug but im not sure those pins are used on the hopper side it may be for a feature igt never used.

[DB26]

Hmmm. I’ll do some more fiddling, but at this point since it is working I might just leave it alone.

If the pins are not populated on the hopper leaving it plugged in won’t matter.

All pins from the hopper are making connections. The spare senet (j7) on the backplane has two pin that are unpopulated.

My wireing diagram shows none if those pins shows none of those pins should be populated on the hopper itself. They show they are there on the machine harness tho. I will check the hopper and harness when i get back to work.
