I think he is just taking exception to the fact that you are claiming ALC is the only product that you can hardwire with a control wire yet still maintain traditional high voltage wiring
There is also the (difficult to find) EDT iLine product too.

Now here's a more specific way to look at your issue. The extended feature works with automation systems like Omni's and Elk controllers. But in your example it does not with the stand alone lighting controller. So what is different? For one thing, there is no time base capabilities with the stand alone lighting controller. I will come back to this thought!
So let's describe "Extended" first. I call it "Ramp over time". It's the ability for the ALC dimmer to take hours to go to the setpoint you gave it. In essence you can tell the ALC dimmer to take all day to gradually come to a setting, say 75%. And the ALC switch is so smooth most bulbs will not "jump" and instead move very smoothly. This is a desireable feature of any dimmer and the ALC dimmer does it superbly.
The time base I mentioned requires some sort of clock. The lighting controller does not have a clock (whereas Omni and Elk controllers have a very powerful clock). To add timed features of any level of sophistication) requires the addition of the lighting manager module. Then you have a robust time clock with capabilites of programming events over several days.
I need to prove this, but I think I finally understand why you are getting no where with the extended commands. You are using them correctly, but the lighting controller does not have the time clock to accomplish what you are asking of it. I should have realized this limitation as soon as noticed the lighting controller had no clock circuitry, crystal or battery.
I'm trying to set the extended ramp rate in my dimmers via the RS232 protocol. I am sending the exact bytes that Bill indicated on the 3rd page of posts of this thread...but all I get back from the controller is NAK.
This is the first 6-byte command I've tried sending...all of the 4-byte commands worked fine. Dunno if that matters.
Anyway, please let me know who to contact about this. thanks.
Now here's a more specific way to look at
Tony,
What you've written about how the ALC extended ramp rate works is not consistent with my observations using an ALC Scene Learning Interface (SLI) controller. The SLI has no clock, crystal, or battery, yet the extended ramp rate works. -Bill

Hey Bill
Great research! You guys really think these things through! Here are some other things to add to your thinking. The SLI in fact does have a clock (it uses the HAI or ELK clock).
The SLI unlike the stand alone SLI lighting controller, links to the processors on-board the HAI or ELK controllers. Actually, this link and the matching of communications from ALC to the HAI/ELK controllers is all that varies from interface to interface. Basically all interfaces: the SLI, the ELk interface and the stand alone lighting controller that Beelzerob uses varies only in these two regards.
We had to change the source code in the SLI models (HAI or ELK) to use the processors present on the main controllers. The amount of power available in the stand alone lighting controller is limited since it can't lean on the HAI or ELK processors as much. Adding the lighting manager gives it back some horsepower.
In addition, all the SLI controllers do have a processor which contains a little bit of ram (which get's it's time base from the system timing). This allows for some time based events, but has limited room for advanced functions. The dimmer and the relay also both have processors, with the same limitations. The extent of how much and how far the on-board processors can go is yet untested by me. Of course on board processing and storage/time base on the stand alone SLI does not compare to that of the HAI/ELK versions dues to the power coming from HAI/ELK controllers.
The on-board processors with these products are not present with most competitive products and are also rarely tested. You folks do a better job of raising the hood and testing that than most anyone.
With dedicated controllers like HAI or Elk's family of controllers, you have the bulk of the processing power handled by those processors and the horsepower found in the switches are rarely taxed if at all. This is also why we never hear any feedback on such issues as this one, since it is basically a non-issue with those models.
When using Beelzerobs setup you can build a rather detailed system. But we are still limited by the amount of area to house programs and by the processor power. For example, you can write 64 scenes using scenetech (or by using the local programing features of the 4 button scene switches). While this may sound like a lot of scenes, it may not have enough horespower for larger installs. Of course the 64 scenes programming would require the addition of the lighting manager.
Frankly, I admit that these scenarios are places where some lab work from us is on the agenda. But balancing these issues against others places them down low in the stack. Still, they are worth some time in the future.
We are looking into replacing the processors inside the dimmers and relays which will give them more processing power. But these design issues will not happen in 2010, closer to late 2011 if at all. The decision involves the old saying "If it ain't broke, don't fix it"!
Let me know what else you find.

OK I did some research by looking at the link you mentioned in post 82. The wired Maestro uses an 18/2 or 22/2 to communicate with the dimmer. That's good. But from the drawings the remote dimmers(3 or 4 ways) talk back to the wired dimmer over the black AC wire? Is that right? I am not sure if this is bad or good! Please elaborate.
Each bus branch supports 8 dimmers. How much would a house with a large number of lights cost as relates to controllers/processors?
Now that I concede to your point, I am now grasping for the next level(s) of comparison - Features, costs, dependability.

Tony,
The SLI (OnQ Part #364614-01, Link to Product PDF) is a standalone controller. I have no HAI or ELK system, nor am I aware of any provision to connect the/this model SLI to an HAI or ELK system.
P.S. Beelzerob theoretically you could enhance your driver to simulated extended ramp dimming with internal timers and discrete dim level commands...

You can attach the 364614-01 to the Elk or HAI controllers using the 364698-01 serial interface board and a serial port on either controller (plus some cables). On the Elk, this was the way it was done before we created the Elk interface.
the stand alone SLI opens up more markets for expansion. As such, it will see some attention and upgrades at some time.

Tony,
I think we're going a bit sideways -- my points were that the SLI supports extended ramp rates as a standalone controller, and that the SLI does not have a 'special' Elk or HAI interface that provides tight coupling as you implied in a previous message. I don't want anyone to be left with the incorrect impression that full-bore automation systems are needed to fully take advantage of the capabilities that ALC provides.

Sounds great!

What if I get an SLI instead of the SEM? Do I need one per branch? Do I still need the HLC?
