PE Plus Upright IBA Keno Pen Harness

[Mikalnm]

Here we go again!  Recently I attempted to make my own harness to connect a Keno Interface board to my PE Plus Upright with IBA.  Basically, I had at least one of the wires wrong and blew a fuse on my machine.  If anyone has this harness (60993600 I think), I would like to buy it!!.   But, with your help, I may be able to wire it correctly this time.  So this is what I have.  I know that the harness connects to J207 on my machine.  It uses 4 of the 6 positions in the molex connector.  I am assuming that this is correct??  Red/Black wire is +VB, Red/Orange is Light Pen +, Red/Yellow is SW 20 (whatever that means) and the Green wire is Light Pen - Ground.  So, what order do they go on the interface board Below?  For simplicity sake since I am apparently brain dead, lets go 1 to 4 starting on the left.  Thanks in advance for any help.

I have collected all of the parts and this is on my list of things to do for my PE+ as well....

When you get this right please document it for others......

Hello All, Not much action on this post so far??  Any advice will help.  So I got out my CHEESEY Multimeter and figured out that Position 3 on the interface board is the ground.  So, any ideas for 1. 2. and 4.? Thanks Again.

A friend of mine has a shop with a lot of random parts.  Next time I'm there I'll ask him if he has the interface board or any information about it.

Michael   went thru some of by books and came up with the following, this is from a slant top manual, it should be the same, the plug number may be different but the inputs should be the same.E.G.  earlier posts indicate P-207 on the upright mother board. On this the plug is P-197, still a six pin plug with only four being used and the same ones you described.

J-197  6 pin molex
Pin 1   +VB     goes to Pin 2  input to pen amplifier
Pin 2   Light Pen +     goes to Pin 1 input to pen amp.
Pin 3   Light Pen SW 20   goes to Pin 4  input to pen amp.
Pin 4   Light Pen  --     goes to Pin 3  input to pen  amp.
Pin 5   N/C
Pin 6   N/C

Hope this helps     Jim

I think there are too many threads of the same stuff going on. I documented the harness yesterday.

Here is the other thread.

Jay     sorry for the duplication     After looking at your post and comparing it to mine, there is difference , or I think there is      the outputs from the connector don't  match up pin for pin  , as they go into the pen amplifier board. According to the schematic layout , the pins don't go  + 1 2 3 4 -, they go  2  4 3 1  ????  Are my eyes crossed from looking at this too long, or can't I see the forest for the trees???

[jay]

No they are not straight through...

I was not sure what order the pins were actually defined so I simply
labled them like the following

SLOT:

1 2 3
x x 4
In this manner.

S     C
1 --- 1
2 --- 4
3 --- 3
4 --- 2

On the contoller end I used the + (on the left) as number 1, and then 2,3,4....

Your scematic above lables the pins in a different fashion .....

I will post a picture of the harness tonight.

Hello All,  This is how I have mine wired now.  It doesn't work.  I do get an intermittent change from 0 to 1 during the self test input test, but the pen will not select any numbers.  The pen and/or pen amp board could be defective (E-Bay Purchases).  Or, most likely, I still have something wrong.  Looking at my primitive diagram, can anyone see where I went wrong.  Many Thanks to ALL!!

[Jim]

If you would follow the diagram I posted you would probably get it to work,hopefully  its not toast from crossing wires!!!  As Jay stated these double posts are confusing!!!!

Listen, molex plugs are labled, hard to see, need a magnifying glass to see, but they are labled.  schematic wiring is the same as the resistor color code,  in our case e.g.  20 -- 22, means    red/ black   22 gauge wire,    23---22  means  red/orange   22  gauge wire,  24 -- 22  means red/yellow  22gauge wire 55 --22  means solid green -- 22gauge wire.

Molex Plug                   Light Pen Amplifier
Pin 1     red/black          Pin 2   +vb
Pin 2     red/orange       Pin  1  +LP
Pin 3     red/yellow        Pin  4  SW 20
Pin 4     Green              Pin  3  -- LP

As you found and stated pin 3(on the light amp) was a ground .

Hope you get it working, hope this helps

Jim

Sorry about the two posts.  I started the other in the classified section as a Want To Buy a Harness.  I did not know this would be confusing. 
OK, I have purchased an IGT Keno Pen Harness.   One Last question.  Two of the positions (3 Red/Black and 4 Green) have and an extra wire with molex pins.  Where do the wires need to go? Any Ideas?

[jay]

The gnd can probably be chasis grounded.
I have the factory harness (will post a pic tonight) and it only has the 4 wires between the two connectors.

Here is the Harness in Pictorial....

Thanks for all the help!  I think I have everything wired correctly now, but I still can not select numbers.  Perhaps I have a faulty Light Pen?  How can I test the Light Pen?   Besides installing the EPROMS, Keno Pen, and Interface Board,  is there anything else that is needed for this game conversion?

[Jim]

Its not necessary, but most keno games have a erase feature,just in case you make a mistake when you select your numbers.

If you open your door and press the self test button there is a light pen input test.

[Mikalnm]

Yes, there is a lightpen test.  However, It only tests the switch (which does work).  Is there a way to check the optic function of the pen?

[jay]

I have not hooked mine up yet. I am thinking a flashlight might change a 0 to 1 much like a door optic does when you intermittently hit it with a beam of light.

[stayouttadabunker]

I wonder if you viewed the end of the pen with a video camera, would you see it lit or flashing then?

No, probably not. You are making a very common incorrect assumption: that the pen does something to the screen.

The pen is passive -- the screen does something to the pen! Unless they designed the PE+ differently from other light pen devices that I've worked with, the way that it works is that the computer calculates where the pen is pointing by keeping track of where the photon beam is in its scan of painting the monitor at the instant that the beam affects the pen.


I don't own one of these machines, but it seems odd that they wouldn't have a test for the pen itself.  It would be an INPUT test, though, not an output test.
Just thinking out loud, they might have an alignment procedure. That might be another avenue to try.

[stayouttadabunker]

That's pretty neat....you learn something new everyday!

[jay]

In Mame you can hook up arcade Guns and play games like house of the dead and I am sure most of my generation will remember Gunmoke.
If you use a LCD screen they don't produce the scanlines necessary to operate the gun.
Same technology as the light pen.
