Help wiring a Point Blank PCB

Post by guncon » September 11th, 2018, 3:43 pm

Hi. I'm new here. I need help wiring a Point Blank PCB with a Namco gun.

This is what I have:
Image

I found this schematic but I'm not sure what to wire were..
Image

I maked this schema of the Position PCB, Gun 1 and Power Supply. Can someone help me with what to wire were?
Image

As you can see I don't have electronical knowedge. I think I only can understand this kind of answer:

J1 conector - Hole 1 - Power Supply 24v
J1 conector - Hole 2 - ...
J1 conector - Hole 3 - ...
J1 conector - Hole 4 - ...
J1 conector - Hole 5 - ...
J1 conector - Hole 6 - ...

J2 conector - Hole 1 - Gun 1 24v
J2 conector - Hole 2 - ...
J2 conector - Hole 3 - ...
J2 conector - Hole 4 - ...
J2 conector - Hole 5 - ...
J2 conector - Hole 6 - ...
J2 conector - Hole 7 - ...
J2 conector - Hole 8 - ...
J2 conector - Hole 9 - ...
J2 conector - Hole 10 - ...
J2 conector - Hole 11 - ...
J2 conector - Hole 12 - ...
J2 conector - Hole 13 - ...
J2 conector - Hole 14 - ...
J2 conector - Hole 15 - ...

J4 conector - Hole 1 - ...
J4 conector - Hole 2 - ...
J4 conector - Hole 3 - ...
J4 conector - Hole 4 - ...
J4 conector - Hole 5 - ...
J4 conector - Hole 6 - ...
J4 conector - Hole 7 - ...
J4 conector - Hole 8 - ...
J4 conector - Hole 9 - ...

Thanks you very much in advance, and sorry for my poor English

Honestly, you've already done most of the work yourself.

This is the part that's important:

J1 is for power input (jump these from the jamma edge and add 24V).

Connect the gun wires to J2.

As for J4, this one I had to look for on the internet. It looks like it needs to be connected to both the jamma edge and the 48 pin auxiliary connector next to it. Normally this would be routed through the filter board (which is why it isn't spelled out on the schematic), but since you don't have it, you need to do it yourself:

J4 Pin 3 -- J101 A6 (GOUT0)
J4 Pin 4 -- J101 B6 (GOUT1)
J4 Pin 6 -- J101 B7 (GOUT2)
J4 Pin 7 -- J101 A8 (GOUT3)
J4 Pin 8 -- JAMMA VIDEO SYNC
J4 Pin 9 -- JAMMA GROUND

Also, two other points you need to notice:

1) Point Blank outputs stereo sound. From the jamma edge you will only get the left channel. For the right channel you will have to tap the 48 pin aux connector:

J101 A1 -- RIGHT SPKR+
J101 B1 -- RIGHT SPKR-

2) The test switch needs to be an ON/OFF one. If you have a momentary push button, it will exit out of the test menu the moment you release the button.

Good luck!

Thanks nem for that very valuable information!

First I'm going to wire the 1P Gun. I also found this diagram of the J2 connector with more information:
Image

And that is what I'm going to do:

As I don't have the cabinet, I'm going to discart wires for lamps.

I'll keep posting next steps and questions :)

While I’m waiting the amp and molex connectors ordered at RS Components, I jumped to other step preparing the 48 pin edge connector, following the information from nem:

J4 Pin 4 -- J101 B6 (GOUT1)

J4 Pin 7 -- J101 A8 (GOUT3)
...

J101 A1 -- RIGHT SPKR+
J101 B1 -- RIGHT SPKR-

The connector I found has 50 instead of 48 pins, but it fits well with the 48 pins on the main board.

The amp and molex connectors arrived.
I wired the J4 with JAMMA and the 48 pin auxiliary connector.

J4 - Hole 1 - JAMMA 1P Button 1
J4 - Hole 2 - JAMMA 2P Button 1
J4 - Hole 3 - 48 pin edge connector A6
J4 - Hole 4 - 48 pin edge connector B6
J4 - Hole 5 - 48 pin edge connector A7
J4 - Hole 6 - 48 pin edge connector B6
J4 - Hole 7 - 48 pin edge connector A8
J4 - Hole 8 - JAMMA C Sync
J4 - Hole 9 - JAMMA GND

Why don't you have jamma connector? Remember you will have to input power and output video and the left channel audio from there as well.

This is going to be my configuration with the JAMMA harness:
Image

I made this change after read your post nem :) :
Image

This is now the new harness with 52 pin JAMMA adaptor, 48 pin secondary edge connector, J1 and J4 amp connector for Position PCB, and a +24v wires for the secondary power supply:
Image

This picture from the other side (maybe useful for someone in the future)
Image

I wired the J1 amp connector for the Position PCB as follow:

J1 - Hole 1 - Power Supply 24v, +24
J1 - Hole 2 - Power Supply 24v, GND
J1 - Hole 3 - JAMMA +5v
J1 - Hole 4 - JAMMA + 12v
J1 - Hole 5 - JAMMA GND
J1 - Hole 6 - JAMMA GND

I just connected all, following advices and diagramas, but I have a doubt looking this diagram:
Image

Do I have to connect +24v from power supply to hole #1 on the J4 J2 connector?

If this Possition PCB gets power from J1 connector, it seems extrange to me that J4 J2 connector was also reciving +24v directly from the power supply...

Don't put +24V anywhere in J4.

J4 has

1 1P_SHOOT
2 2P_SHOOT
3 GOUT0
4 GOUT1
5 GOUT2
6 GOUT3
7 GOUT4
8 C_SYNC
9 GND

There's no +24V.

Remember the schematic includes the filter board which you don't have. Don't read too much into the connections.

Sorry, I typed J4 instead J2..

Do you think that I don't have to put +24v there?

24v would be for the recoil solenoid if the gun has that.

Most likely one connector is meant for input, the other one for output (to gun).
