Eric, Yeah, after I looked a little closer I noticed the LED profile on the silk-screen. So far so good. My digitemp software seems to detect all the coupler devices within the hub. I just need to re-wire up some probes to see if its really working. Thanks for the help. Mike

Eric, I got a new multimeter and its like an awakening. :-) The regulator appears to putting out .3 mV on the center pin and 5.12V on the third pin. I reversed the green LED and it works! I'm assuming I need to reverse the other LEDs as well. Mike

Eric, I just so happen to have recently purchased a portable car battery jump-starter. Its fully charged at ~14V. My multimeter doesn't read any voltage. I think my multimeter is bad. I'm going to replace it and I'll let you know what I am able to see. Mike

Eric, I'm somewhat at a loss as to how to test the regulator. I'm somewhat of a hack when it comes to using my multi-meter. I thought I could test the powersupply by probing the inside of the power jack (from the adapter) with the red lead and the outside with the black lead but I get...

Eric, I just built the new replacement master hub kit that I ordered last week. I used solder this time and I think I did a reasonable job of putting it together. ie. no major mishaps. I am right back to where I was before. This board doesn't show any signs of life with the green LED when I...

Thanks David. I was using the resistance setting on the meter but I don't think I was using a proper ground. I'll check it again. I left the iron on some of the joints for a long time. It was long enough to see the flux start to boil. I actually had one part melt a little (I had some...

Just a bit more information on my technique. I googled surface mount soldering advice. Here is a bulletized breakdown of my approach: - used a rosin flux pen, I read somewhere to not use solder paste. - did not use solder for the surface mounts parts (see *'s below), I read online that the...

Hi, I just finished building a 6-channel Master Hub and I think it may be DOA. I admit that this was my first surface mount solder job so its quite possible I've cooked something. I've tested all the components and they appear to be firmly attached. I haven't connected the serial cable yet...
