shobley Posted August 20, 2007 Report Share Posted August 20, 2007 Hi,I've only just got around to assembling my MIDIBOX CORE Rev3 I bought in 2005.I've put it together and I've completed the ground tests - checks out OK.I've tested +Ve and with a 9V battery on J1 I get 5.06V on all test pins apart from pin 11 on the MIDIBOX PIC (Bootstrap V 1.01B)On my PCB this pin is only connected to one of the jumper pins in J5 - so I don't know where it's going to get +5V from.Any help with what I should do next would be appreciated.Thanks,Steve Quote Link to comment Share on other sites More sharing options...
stryd_one Posted August 20, 2007 Report Share Posted August 20, 2007 Heya shobley. I'm glad you've taken so long, because I am now the 2nd slowest midiboxer :DThis is from TK's voltage test document. Take note of the bold parts:Pin 11 should not be connected to J5...

shobley Posted August 20, 2007 Author Report Share Posted August 20, 2007 Hmmm I guess I was counting wrong. All the test points you gave me check out.So I'm good to go?:)How do I test it once I put the chips in?Steve Quote Link to comment Share on other sites More sharing options...
