HELP: Connecting & Configuring 2 IPAC-4 together for MAME
alfredov:
Hello Everyone,
I am new to this forum and was hoping someone could help me with my mame project. I need help connecting and configuring 2 IPAC-4 (56x2 input) together. Ive spend many hours researching the web and reading off of IPAC-4 website but still am unable to succeed.
My setup consists of:
P1 = (8Way) Joystick + 8 buttons
P2 = (8Way) Joystick + 8 buttons
P3 = (8Way) Joystick + 8 buttons
P4 = (8Way) Joystick + 8 buttons
P5 = (8Way) Joystick
P1 Start, P1 Coin
P2 Start, P2 Coin
P3 Start, P3 Coin
P4 Start, P4 Coin
Escape

Tab
Enter
Pause

For reference, you can see my controller here: https://pbs.twimg.com/media/B3_UuNnCEAEMVwH.jpg
As you can see from my setup above, I need a total of 68 inputs. Inputs for the first IPAC4 up to input 56 work perfect. As soon as I attach the secondary IPAC4 via the pass-through of the first and connect my extra buttons to it, the IPAC4 program thinks that I have only 1 IPAC4 so when pressing buttons that are assigned to my secondary IPAC4 it just mimics the same inputs as what the first IPAC4 is setup for. How do I configure and assign other buttons to whats connected to my secondary IPAC4?

First off you should include the pic in the post. There are two ways to do this.
One: Attach it under the post by clicking on the plus sine under the box where you wright the post.
The second is to post the pick in http://forum.arcadecontrols.com/index.php/topic,136713.msg1481659.html#msg1481659
Then copy the image location, use the insert image tab, and paste the address between the internet magic stuff.
Like this.
If it was my build I would ask my self what games I would need all of these inputs for. Then if there was that one game I needed this setup for I'd get a cheep zero delay encoder for P5 and use a shift key for all that admin stuff in on the I-pac.
You could also get a KeyWiz40 to be your second encoder. http://groovygamegear.com/webstore/index.php?main_page=product_info&products_id=303&zenid=3vdfhbapsvb351ogjq6cprdma5
Andy my have a way to make this whole two I-pac4 thing to work. Again, I would ask my self "Do I really need all these inputs?"

Would have to agree with this -- Is there any game that would ever use that many inputs - I can't think of any - figure pretty much any 4 player game uses fewer than 3 buttons for the 4 players - so there's 10 buttons that will never get used (buttons 4-8 on players 3 and 4) - Makes no sense to have a player 5 either so there's 4 more inputs wasted ( If you are wanting it as a dedicated 4 way for pacman etc. just wire it in tandem with player 1 joystick) - Figure just that adjustment brings you down to fewer than the 1 I-pac 4 provides - so then you have an extra I-pac 4 to sell or use for the next build ( or trade to Malenko for an I-pac 2 and a bit of cash - See his thread in the Buy Sell Trade sub forum !! - Linkie ( http://forum.arcadecontrols.com/index.php/topic,142922.0.html ))

+1 With the caveat there are some modern 4 player steam games like hammer watch that need at least 6 buttons to be playable.
That is why I have 6 buttons + two admin for all four players on my pedestal.

Ahh forgot about the steam games -- Malenko does mention the Keywiz in his trade thread so maybe trading him the I-pac 4 for the Keywiz would work then !
