Title: Help: Sanwa JLF (5-pin harness) --> IPAC2 wiring?
Post by: corysnyder28 on July 08, 2016, 02:31:53 am

Hi all - I'm setting up my system and have run into some wiring questions that have me (a general wiring noob) pretty stumped -- hoping you guys might be able to help. Thank you!

My gear:

* 2 x Sanwa JLF-TP-8YT joysticks w 5-pin wiring harness cables (link: www.focusattack.com/5-pin-wiring-harness/ (http://www.focusattack.com/5-pin-wiring-harness/)
* 12 x Ultimarc Goldleaf action buttons
* 6 x Seimitsu PS-14-DN-C admin buttons
* 2 x 10 Connection 22 AWG .110" Ground Daisy Chain Wire (link: www.focusattack.com/10-connection-22-awg-110-ground-daisy-chain-wire (http://www.focusattack.com/10-connection-22-awg-110-ground-daisy-chain-wire)]
* 1 x IPAC2 encoder

My issue:

I have 5-pin wiring harness cables connected to each of my 2 Sanwa JLF joysticks. Those harnesses each have a black ground wire.

I have one of the 10-connection daisy chain wiresets daisy chained across my player 6 player 1 action buttons + 3 player 1 admin buttons.
Similarly my other 10-connection daisy chain wires is daisy chained across my player 2 buttons.

Between the two 5-pin wiring harnesses and two 10-connection daisy chain wires, I have four ground wires. But only two ground wire slots on the IPAC. So right now the joysticks are registering fine and none of the buttons are registering.
 
.

My question:

If I connect those joysticks' ground wires (2 in total) to the IPAC, I have no remaining ground slots on the IPAC to connect the ground wire(s) from the daisy chains I've set up between by action and admin buttons.

How do I connect my two remaining ground wires so that my buttons are recognized by the IPAC?  Do I need to connect them to each other or somehow integrate them into the daisy chain?

thanks!

Just put several wires into one ground slot. Ground is ground, it's shared between all input devices (buttons and sticks). The two ground slots on the IPAC2 are connected internally. They are the same and it doesn't matter which one you use.

Never assume that black is ground, or rely on colour coding for pinouts period.

(http://wiki.arcadeotaku.com/images/thumb/e/e6/Jst-nh-5pin.jpg/700px-Jst-nh-5pin.jpg)

1) GND -
2) DOWN
3) UP
4) RIGHT
5) LEFT

This pinout is when the connector on the pcb is facing upwards - i.e the same direction you would push the joystick for UP.
