    DMX is a fairly easy COM's protocol to work with, but it has quirks if you've never worked with it. PM me if you have questions about the DIM-12 or the DMXcat; I realize I approach things differently since I work in the Entertainment industry. What is standard hardware for me is often oddball for many others.

    You'll need (42) dimmer packs to control (500) channels. Since you can only place (32) DMX-controlled devices in a daisy chain before you run into signal problems, you'll need an optosplitter. Put (10) or (11) dimmer packs on each leg of the splitter:

    2. The owner wants the capability of controlling each light fixture independently.
    3. I am building the system to accommodate approximately 500 fixtures.
    4. He would ideally like to be able to have his sales people be able to control the switching from an iPad or wall mount controller. Ideally an iPad.

    I do not need to know about figuring the power requirements. I am looking for recommendations on controllers or systems with such a capability. Maybe someone has installed a similar system and knows a specific brand to accommodate this. I know I can call different lighting reps, but before I get to that point I am looking for some recommendations.

    Thanks for your help!
    ok. by god, we can do this if it takes every penny he has.

    nLight will be a good place to start. you can blow him out
    of the water with a half hours work. this will save you a
    lot of unpaid time.

    you can thank us later.

    it's a plug togeather system that is modular, and scaleable.
    pretty easy to program.

    500 switchlegs, and a custom panel with pretty push buttons
    would be cheaper.

    now, an nlight programmable dimming module for one channel
    is about $60.

    that's $30,000. for parts, and not all the parts you need.

    for 500 controllable points. switches are unwieldy.
    that leaves a custom interface on an ios device to be built.

    so, by the time you do the physical install, a huge strut array
    to support the lights with j boxes on it to deliver connection
    points, a custom programmed interface, i'd call it $80k~$90k.

    how many light fixtures is he going to need to sell, to pay for this?
    how many can he sell off a website that can be built for $20K?

    I love the reply!!!! I have communicated the potential cost for all of this and he is adamant about moving forward. He still pays my bill, so I am going to continue to try to find the solution that works the best per cost for the customer.

    +1 for the DMX if you want fine grained control.
    I would look to a 24VAC DIN mount relay system. As you can then abstract the 24VAC to a PLC or why not a DMX controller.
    Avoid the conventional store lighting contactor blocks that use one coil to drive "contact blocks" like the GE CR460.

    You folks are over engineering this.
    You can use a simple wireless module at each fixture box. Insteon , zwave , zigbee.
    You will need to use several networks and link together.
    Probably half the price of Nlight and less proprietary.

    Still going to be in the tens of thousands.

    The wireless is a concern for me as this is a large metal building. I have looked at both of those options, but looking at the specs there are potential communication issues with the distance and then there will be large groups of them together. The sales rep agreed interference from the other devices could be an issue.

    After talking to the owner and letting him have a little sticker shock, we are scaling it back. I am building a simple control panel with off delay timers and relays to manage groups of lighting.
