So I'm setting up my Xbox on my Taito Egret 2 cab with the J-Pac set-up. Trouble is, when it boots up, the picture looks all crappy and pixelated. On other occasions it obviously isn't outputting at the right resolution. What am I doing wrong? Which jumpers must I have set for my 15/24HZ arcade monitor? Also, is there anyway I can damage my arcade monitor using the J-Pac? Or is it foolproof? Thanks (in advance) to anyone who can help me! :) |

Your Xbox is putting out a signal for TV. The Jpac only protects the monitor but it does not convert the TV signal to an arcade monitor. You are missing a piece of hardware. Being an Xbox its outside the usual PC answer- and arcadeVGA or soft15lhz) I suspect you will need something like this http://www.arcadeparts.com/monitors/49272710.htm. |

Strange - it seems to imply on the Ultimarc website that it converts to 15KHZ... http://www.ultimarc.com/xba.html You did get me thinking though... if you changed the settings on your Xbox from 50MHZ to 60MHZ would this make a difference? Also, how about if you changed the settings of your Xbox to be able to output in HD would this make a difference too? Thanks for the response! :cheers: |

The J-pac does output 15Khz- but it does not control the picture If you were PC based, using all ultimarc products , you'd use a J-Pac and an ArcadeVGA. From the J-Pac FAQ --- Quote ---IMPORTANT: It is not a scan converter so you will have to configure the VGA card to send the correct sync rate for the monitor OR you can use our ArcadeVGA card which will drive a 15Khz monitor with no special configuration. --- End quote --- Now because you are using an Xbox its different. But you still have to convert the picture itself to 15Khz- whih is why you are getting a poor picture. Theres another approach here http://chrisevans3d.com/hardware/cabinet.htm |

The Xbox outputs a 15Khz picture which should be compatible with an arcade monitor. If you are using our Xbox to J-PAC AV adaptor this should work. Possible issues: The J-PAC needs to also be connected to the Xbox control adaptor otherwise it will have no power. You need to remove any red jumpers form the J-PAC sync pins to enable composite sync from the Xbox to pass through the J-PAC. Otherwise drop me an email. Andy |
