So I've been troubleshooting about how my DMX output hasn't been working out of my active hub when my smartstrings have been working great - I've set the DMX universe to 1 and was expecting to see the first 512 channels working on my set of Express's. At first I was thinking that I was not setting up LightShowPro correctly (setting it up as a 'Light Controller' with a 'Pixelnet/SmartString' Controller Protocol) but after looking over the board a bit, I saw that my 3W resistor was very hot and had char marks on the back traces. After looking at the manual on the wiki, I saw the small note that the wrong shipment of resistors went out in the co-op. Since it's almost impossible to see the colors on the resistor anymore, I assume I installed the 15Ohm instead of the 100.
Would a scorched resistor cause that whole half of the board to not be working? I saw that the closest 485 chip seems to lead down to the DMX output, so my gut was thinking it may be the case.
I can order the replacement from mouser, but in the short term, is it acceptable to pick up a 100 Ohm 10W power resistor from RadioShack in the interim? http://www.radioshack.com/product/index.jsp?productId=2062293&filterName=Type&filterValue=Power+resistors (http://www.radioshack.com/product/index.jsp?productId=2062293&filterName=Type&filterValue=Power+resistors)

I believe that RJ has them. PM him and ask
Rick R.

Thanks Rick, I'll go that route for the replacement.
That being said, should I stop troubleshooting the DMX output and blame the hot resistor? Or should I order up a fresh ST485BN while I'm at it?

You can just go to paypal and sen RJ .01 to make a shipping reciept and he will send it to you.
