I've rechecked the wiring scheme, and it matches what the protocol doc says in the back. I've verified the device address is 1. So when I send the bytes: 010203 That should be requesting group 1 values for address 1, correct? I couldn't think of an easier or more foolproof way to verify...

If it's a dimmer, then holding the switch in the on or off position changes the bulb setting. But for a relay, the press-and-hold functionality doesn't do anything. I'm planning on using one of my relays to control a dust collector, and I'm coming up with a scheme on how to control it based on...

My wood workshop is coming together, but I'm suddenly stymied. I have built a closet for my dust collector to go into so that it would not be such a noise maker in the work area. But I needed some easy way to control it as well so that it'd be trivial to turn it on. My plan was to use a spare...

We're adding some walls downstairs, where the low voltage up until now has had a free reign. Now I need to add some regular 14/2 wire for some plugins and I need to route the wire across the hall to where the power panel will be. All of the low voltage runs in the side of the I-beam up top...

I'm getting into crunch time to decide on and procure a thermostat for our new geothermal system/zoning/humidifier. I'm still liking the Honeywell VisionPro IAQ setup, but the difficulty in getting the protocol is legendary. I have C function stubs, and there's a chance at least that I can...

I'm tired of fearing for my wretched DLP TV and it's $300+ bulb whenever the lights flicker, so I'm finally going to get a simple UPS so I'll have time to turn it off and let it cool if the power goes out. I measured it with a killawatt at about I think 110 watts while running. I would only...

Since I've determined that the garage is no longer big enough for my woodworking passions (such as they are), I decided to make some use of our basement, since it is hardly being used at all right now. It gives me lots of room in a relatively year-round friendly environment. Here is the...

I'm sick to death of having to turn on the wife's computer to use our one printer. I had bought a netgear USB print server about 3 years ago, and have never gotten it to *reliably* work. It is certainly harder to configure than anything on this earth should be. So, I'm just going to roll the...

So, as part of my geothermal adventure, I have to secure a thermostat to handle the requirements. I currently have a RCS TR-15 that has worked good enough for my existing heat pump. But since I'm upgrading everything else, I might as well go fancy on the thermostat too. I've looked over all...

You guy still around? :) I've sent ya both PM's in the past few days, and no response from either. Most pertinently, I sent Dan a PM about the blogs...it won't seem to let me create a new entry. No errors or anything...it just doesn't show what I've just entered.

This is a continuation of a discussion in the Legrand thread, and this topic begins in post 43. Basically, I've written a CQC driver to interface with the ALC lighting control module, using the RS232 protocol. And in almost all respects, it works just great. The only problem I've had is with...

I've had this for a while, and never bothered to use it. I might be starting to bother. It has 6 inputs and 4 outputs (or vice versa)...each card has 4 connectors on it. I'm not doing a lot of distributed video lately, but here's some thoughts of things I wondered if I could switch: 1)...

The original thread for this dealt with the ebay deal for picking one up, and since then has become the catchall for all things Quatech. This thread is devoted to using the Quatech serial port devices, in particular the QSE-100D 4-port IP box. But feel free to post about any Quatech device.

While moving my motherboard from 1 case to another, I gave it a look over and saw this: I know blown caps are an issue, but I've so far avoided it. The motherboard still works, so I dont think it's gone yet, but how long do I have? Would it be better not to use this board, or is that cap...

I've noticed a need for something for a while, and this last weekend it finally culminated in a big issue. We have a steam shower that is fully enclosed. Once you close that door, you basically can't hear anything outside. The door is wavy glass, so you can kind of see things...but hear them...

Since i've got a PC running 24.7 for CQC anyway, I've decided I might as well put it to better use doing something like backup. The ease of use and automatic nature of WHS appeals to doing that. Here's mainly what I want it to do: 1) Be my CQC server 2) Backup all the PC's connected to it 3)...

It's great when you get to the point where your wife makes suggestions for ways to improve how the house works. We have a fairly frequent issue of our little girls running (literally) to our room at night in the relative dark. We currently have about 5 nightlights lining the route, but it's...

Cant' access them yet this morning. Sent an email to Dean, but haven't heard yet if its his issue or mine. Maybe he's not awake yet (ya, right....)

I've been using TightVNC for quite some time to be able to affect changes on all PC's in the house without having to leave the extreme comfort of our computing loft. But now I've introduced a Win2k PC into the mix, and I can't log into it. The software starts up fine, and when I try to vnc...

So I began to realize that my TTS wasn't working anymore. So, I went over and did the first check, which was to make sure the PC volume was up. So I clicked the little speaker icon, and ya, the slider was up near the top. I clicked on the slider, and you know how normally that should produce a...
