brooselee Posted January 23, 2022 Report Share Posted January 23, 2022 Posted this on the FB page as well: Purchased a used box. Previous owner couldn't get it working so pulled the mod chip out. I can't seem to find the installation manual/wiring diagram for the chip. Checked archives, OGXBOX, reddit, Google, and nothing. It's an Xecuter 2.0 pro. No dip switch/lpt daughter board, but I was able to get the chip working. It has the 2 pin plug tagged to ground, and the other wire, which I am assuming goes to d0, but is also spliced into the controller 1 USB daughter board. It was pulled apart, but splicing it back together boots the chip. I did a couple x3's back in the day and recently did an OpenXenium. I have never had to splice into USB. I am assuming it's for power. But d0 needs to be grounded to boot the chip. Haven't tested with a meter yet, but I feel like it's sloppy and just not right. Hoping one of you fine people can help. Pulling it back apart today to pull the clock cap and clean it up, so I can post pics if needed. *Edit. Pulled apart and added pics. There are two splices, one to add length to the d0, and the one that is spliced to the USB is running to pin 13 (mode 3) on the AV socket and doesn't go to the chip at all. Some kind of trace repair? https://imgur.com/gallery/nASUVhI Quote Link to comment Share on other sites More sharing options...
brooselee Posted January 23, 2022 Author Report Share Posted January 23, 2022 Looks like we figured it out on the FB group. Posting a link to that for future reference for anyone else. Group is private, but if you're in this forum, it should be easy to get in there with a quick and easy survey. https://m.facebook.com/groups/ogxbox/permalink/3130801280523940/ Quote Link to comment Share on other sites More sharing options...
KaosEngineer Posted January 24, 2022 Report Share Posted January 24, 2022 The previous owner must have added a switch to their controller and disconnected the light gun sync (yellow) wire of the controller cable to use it to switch AV modes for some reason. Not exactly sure why one would do so though. The AV mode the console starts in is determined by the type of connected AV cable which grounds (0) or leaves disconnected (1) the three mode pins. See xboxdevwiki.net's information about on the Xbox's AV cables: https://xboxdevwiki.net/AV_Cables There's a table included there that shows the various modes that are selected by all three not just one mode pin's state when the Xbox is powered on. Note: The pin numbering that xboxdevwiki.net uses is different than I normally use. They've numbered the pins 1-12 and 13-24 instead of having all the odd pins on one side and the even numbers on the other. Following what's seen on this web page: Microsoft Xbox A/V Pinout (gamesx.com) Hmm, looks like that pinout has pin 1 on the opposite side of the connector too. Here's what I always use for pin numbering of the AVIP port: 1 Quote Link to comment Share on other sites More sharing options...
