Losing IDs

   I posted this reply in a post at d-light but thought I'd put it here too...

First of all, today I added second power cords to each of my two original ACx16s because last year when I built the two silvers, I used jumpers to connect the two sides on each of those original controllers. So I had unit 1 and unit 3 with one power input on each of them for a total of two. Now there's power to each side of those original silver units for a total of four inputs just like on the two platinums I bought this year. I also built a 100amp subpanel and each of the four controllers, eight power inputs in all, have a 15 amp breaker. I broke out the ol' Kill-A-Watt meter and checked each extension cord for the amp load and I confirmed that I am below capacity. I started the show tonight and watched about 5 sequences. No problems. I thought, "WOW!" and left to get some dinner. When I got home, unit 1 and 3 were not responding. I shut dow Borealis and reset the id on both 1 and 3 and started back up. MIRACLE! Worked again... for about two runs through a 12 song show... then unit 3 crapped out. No kicked breaker. they just lose their id's.

Nope, not always the second sequence and not always the same sequence.
Ideas?

	Who made the ISL8487 chip? If its an Intersil, change that sucker out with a TI. Has cured more than few lost ID problems in the past.

	Exactly what lightchristmas said the same thing nearly drove me crazy 2 years ago! Even if you have a TI IC19 swap that chip with a known good one and see if the problem follows that chip then you'll know.
