Do you have the volume up, down and reject connected - does it respond to these? If it does, it must be something in the programming! In which case, it might be worth running through the program locations and making sure they have valid entries.

The volume and cancel work but they are connected to S602. The free play switch I made based upon your diagram is connected to S603. I'll go back through the programming and see if I see anything but I have a gut feeling there is a lock out code somewhere.

Although the volume and reject inputs are on a different socket to the remote, they interface to the same chip in the control centre - so the fact they work pretty much proves the hardware. I once had a machine where only the volume up worked and I got it working by sorting out some corrupt entries in the programming locations - so worth a look!

Norman, Could you please check your manual and tell me what the volume pot value is?
Thanks,
Scott

Hi Scott,
I'm not sure what you mean by "volume control pot"? The volume control itself is digital - if you look back to the previous page where I posted the picture of the volume and reset, you will see the hardware for the volume "up" and "down" is just two switches. Are you having trouble with the amplifier control or is your question still related to the free play issues?
Norman.

If you look at the picture you sent me, one of the options is an analogue volume pot. The schematic shows the pots but doesn't show the value. If used that way, the pot is connected to LK and RK on the interface board. When using the analogue pots instead of the digital buttons, the two switches on the interface board are supposed to be moved pointing inward to the board.
I have not been able to get the free play working. Speaking with Mark at NSM Jukebox Repairs in East Yorkshire England, we have come to the conclusion there must something in the credit computer that is wonky. He did help me determine S6 pins 2 and 4 would be the key switch and, assuming P10 is set to 254 or 255, momentarily connecting these pins should activate free play. Instead it only adds one credit.
Which brings me back to my question. My idea is to replace the volume down (middle) button with a pot and connect the volume up button as a free credit switch. This will allow credit, volume and cancel without drilling any additional holes anywhere. Not my first choice of solutions but easier than sending the credit computer to England for repair.
Scott
PS: Correct me if I'm wrong but it doesn't appear these units have a factory reset. I was thinking that may clear any erroneous settings but it doesn't appear to be an option.

Hi Scott, Yes indeed you are correct! This morning I had looked through the written manual I have, to check if there was anything about a volume control - but nothing! I have had another quick look at the schematics and I cannot see anything further but I will look more closely tomorrow! The pots shown in the drawings do go to the amp (pin 10 on both channels) and there is a 2.2k pot on the amp side of pin 10. I see another * (other than the pots) on the pic I sent you, maybe there is a note somewhere and I've missed it! I don't know of any factory reset. I'm also wondering whether the fact that the free credit only adds one credit should be telling us something?
Edit - I've had another thought! What happens if you enter 255 and keep the free play button pressed, does it only just add one credit or does it keep incrementing?
Whereabouts are you located? Norman. |

It only adds one credit no matter how I do it.

Hi Scott,
The more I look into this, the more confused I become! I cannot find any other information on analog volume controls other than what I've provided already. I have looked at every schematic that I have and I suspect that there must have been separate instructions regarding the volume control.
On the Control & Credit Unit Schematic, volume and reject are specifically identified and connected to a totally different area to that of the remote control. However when I trace through these volumes up and down, I find that they connect via S600 and to the two controls (although I can't decide exactly what that symbol means?) adjacent to the asterisks on the Configurations Plate - see picture I posted. Do you have these? As far as I can see, there can be four different methods of controlling volume! You previously said that your volume up & down was connected to S602 which would route it to the remote control area of the CCU.
Norman.

I am sure I did not get all details from this post. But today I found this from an AUS distributor in my files and thought I post it anyway:
In general there is a key code programmed to those models. NSM used 0000 but each operator could have made his own. If a key code is programmed it is needed for making changes.
Sorry I don't know anything about the vol. pots. The parts list shows a digital and also a stereo analog with two sliders and a mono with one slider remote volume controls.

Good point about the key code, Hildegard!

So what parameter (P#) do I go to in order to enter the key code? It was my understanding that I couldn't make any changes if there was a key code programmed in. I can make changes, they just don't do anything.

"I can make changes, they just don't do anything" - does that not equate to not allowing changes? The operation of the key code is covered in the programming document.

Maybe I didn't say it well enough. I can change the parameters and they stay, meaning if I set P10 to 255 then go back to P10 for instance it will still show 255 but it doesn't activate the free play. The programming document I have doesn't say much. The closest thing I can find to what might be the key code would be P49 which states "Legitimation to enter keyed programme". |

Hi Scott,
I'm afraid that I have now pretty much reached my limit here! The coding is covered in the document that I gave you via Dropbox. You could go to P49 and enter the code 0000, PPPP will appear on display 2. If you press the top ten button and 0000 is the correct code, PPPP will then move to display 3. If it stays on display 2, then 0000 is not the correct code. That would at least let you know whether the code was still the factory set one or whether it had been subsequently changed.
Norman.
