Ok, to be clear, I program the pic, checksums are correct. I put the program jumper on, hook up to hub, run utility, nothing happens. No rapid flashing. Remove jumper. Go back to the pickit3 to look and the checksum is different.
Checked the orientation and numbers on all chips on the hub. They are in correctly and oriented properly. I have the shunts on all universe 1's like in the manual. Sorry about this, I am stumped at what could be going on. I'll see if I can post pics of the hub and an ssc.
Also, ran all cat5 cables through my tester and they all check out OK.
