Title: JPAC Sending Key Continuously
Post by: tcavazos on September 27, 2007, 09:35:58 pm

I have exhausted my testing and searching to correct my issue.

I purchased a JPAC and connected to my JAMMA setup. Originally when I setup the JPAC none of the buttons matched up with the default setup. I was however able to program to correct.

My issue now, after I rebooted the machine I receive numerous blinking lights at boot up. Within windows xp I open notepad and go into programming mode and it tells me 1 sw 3 is pressed or shorted. In testing I removed the JAMMA connector and keyboard and rebooted the machine. On restart the JPAC is sending the pressed or shorted issue (space button). No other input device is connected and the JPAC is sending space button command continuously to the machine.

The JPAC is connected via USB.
 
Please help!

check your wiring, some loose connection or something.  My cab was going nuts for two days, some of the dollar store electrical tape got loose. my cab would escape when i would press pause and throw fireballs with streetfighter II. My player 2 buttons would act like my player 1 joystick, reboot computer start working fine, reboot stopped working at all.  Nothing was touching, the loose connections would make it give wrong signals to the encoder i guess. Re tapped a few wires and everything is fine now.

I had a similar issue. Thought my Keywiz had left me :hissy:
Turned out my son had been jamming pennies in it for credits...one fell through and lodged the credit swith on the coin mech in the "on" position.

Yup same thing happened to me, turned out to be the wires connecting to my coin mech. A little insulation tape fixed it.

Thanks for the responses, I have added more info for clarification.

For testing...

The JAMMA harness is not connected to the JPAC nor the keyboard. I only have the computer, monitor, and JPAC connected. This means no switches or input device (besides the JPAC) are connected. Yet the computer is registering the JPAC as sending the continuous key (Space Bar). As soon as I unplug the JPAC (USB) the continuous key (Space Bar) stops. What can I do to stop/reset the JPAC?

I hope this information helps.

I would contact Andy at Ultimarc. He should be able to help you problem solve this.

Sent an email to Andy. No reply yet. Just hoping someone here could help me. A lot of knowledge on this board.

Well I was going to suggest using WinIPAC to reset back to defaults, but then I realised JPAC is a different ballgame. It screams out wiring problem but I have never worked with a Jamma harness.

Let me know if you have still not received a reply, because that means I did not receive the email for some reason.
Thanks

I have a similar problem with a couple of J-PACs I bought a few years back.

But the cabinet I have it hooked to doesn't use the button it says is stuck on, so I never bothered contacting Andy.

I am thinking of making a two player/six button per player cab, so maybe I finally should.
