    Litepak model 600

    Fixing these things is a breeze if you have an oscilloscope, and really difficult without one. The general rule for these things, once they were finished at the factory, was that if they didn't work there was usually only one or at most two things wrong. To fix them, you had to figure out what...

    Litepak model 600

    Thanks for posting a picture - sorry I was a bit abrupt, but it was a long week in the salt mines and I work with a computer security group that keeps hammering home the "don't download something you don't know about" message. And XML files can contain executables, so they're particularly...

    Litepak model 600

    I have neither the ability nor the willingness to download an xml file and figure out what it says. English text, yes. XML, no. Your call.

    What do you want to know? I designed it.

    Aha! Well then, the most pertinent question for you: are you still fixing planes?

    The new old guy signs in

    Hi Steve! Thanks for catching me up on their whereabouts. I'm glad things worked out well for you and you've a great gig with ETC. I really enjoyed the venerable Mr. Moore - very knowledgeable and very personable. Patrice was a load of fun too, but she was at Kliegl when I knew her in the...

    1. we built an analog demux that worked properly with the serial analog protocol for the CD80. We didn't do our own. 2. a combination of factors. First, we had a new President that didn't understand the industry, so when we were awarded the Tampa Bay Performing Arts Center contract, he...

    "NormS" eh? Did you perhaps work on building them?

    K96? I remember the name but I can't put a face to it. Whatever became of Martin Moore? Patrice Sutton?

    Hello from Bruges, Belgium

    Bruges is a lovely place. I was there once with a business associate that showed me the "family home" where he'd been born. His family had been living there since 1308 AD.

    I don't know the state of the art in dimmer control protocols, so maybe this is a dumb question, but has anyone built the fade management engine into the dimmer's own control circuitry yet? If not, why not? Back in 1984, Dilor built a computerized console called the DGM, for Dimmer Grouping...

    So, Steve Terry actually IS fixing the control protocol mess. I guess I shouldn't be offering editorial comments just yet. As for bidirectional communication, I presume that will be more useful for high-tech fixtures than for dimmers. Dimmers are remarkably dumb. They couldn't tell a...

    Thanks for the welcome! I did a little digging on what ACN means, and it sounds useful. My gig was dimmers more than controls, though. Sure, slider controls with PWM fading and lossless diodes and so on, but basically one wire-one dimmer. The CD80 protocol that (I guess) Dave Cunningham came...

    Dilor Litepak Control voltage

    Ahh! So the modules were triples! I couldn't remember directly, but the packaging logic we used would have led us to a triple and not a quad. Usually quads were one phase per module, and triples would be three phases per module. For permanent installations, it didn't really matter and quads...

    The cream with brown lettering 12 channel Litepaks were lighter, smaller and easier to use than what came before. If you ever hooked up an EDI Scrimmer portable dimmer, you'll know what I mean. Our initial customer was a lighting rental shop in North Vancouver and our goal was to have a...
