I purchased and Ipac4 not to long ago and for awhile everything worked great out of the box.
But just recently I was using my arcade and the Player 1-left stoped working ?
I went into Winipac and tried to trouble shoot nothing was showing up for 1p-left went into notepad tried to see if it had a function nothing all other buttons worked. I counted the flashes on the ipac4 and it turned out to be 15 which is according to the chart on ultimarc website leads right to 1-player left .. I also took a volt meter to the ipac and all inputs were giving 4volts average and 1 player left was showing just under 2

??
Is this a faulty ipac or what could my problem be ?
