J-PAC given a facelift
AndyWarne:
As of today all J-PAC boards shipped will be an updated version.
New features are:
ESD static protection on all JAMMA inputs.
Protection against being plugged in backwards (although we would still not advise testing this feature!).
Supports 12 volt coin doors with no voltage issues.
Supports Service Switch, Tilt and Test JAMMA pins (fixed keycodes, F1, F2, F3)
Turnarcades:
Excellent news that even well-established products are still monitored and considered for improvements - Great work Andy. :cheers:

I don't get it. I see enough contacts for one stick and only one button (let alone the extra three on later games) per player. What am I missing?

Great news Andy !! :applaud: :applaud:

Ensure that if the cabinet has an electronic coin door, this sends a 5 volt signal, not a 12 volt, otherwise the J-PAC will be damaged.

Does this mean the J-PAC is now compatible with NRI coin mech's, such as the NRI G-13.6000 :

I'm planning to buy a cabinet that has one of these installed, and then "rig it all up" to a J-PAC.

Take the effort to read the FAQ first ::)
What controls does the JAMMA connector support?
The JAMMA standard supports 2 players with 3 buttons per player. There is an unofficial addition to this, some cabinets wire a fourth button. Plus coin, start etc.
Thats not many buttons, what about any others?
Game boards which need more buttons have an auxiliary button connector which can vary in type. This is not part of the JAMMA standard. The J-PAC caters for these extra buttons by having screw terminal inputs for these extra inputs.
Inputs supported directly through the JAMMA connector are:
Player 1 and 2 joysticks, Player 1 and 2 buttons 1,2,3,4. Coin 1, Coin 2, Start1, Start2.
Inputs supported by the screw terminals are:
Player 1 and 2 buttons 4,5,6,7,8.
Note that button 4 can be connected via either method as some JAMMA harnesses route this button through the connector.
If you have a 4 player cabinet you can use an I-PAC2 board as well as a J-PAC and plug the I-PAC into the pass-through connector of the J-PAC. You will need to re-program the I-PAC board for correct player 3 and 4 keycodes.
I ordered a J-Pac from Ozsticks. I hope Chris will send me the new version :laugh:
