I read the thread about the IR543AH,and I am very interested in it. I'm waiting for a company in the U.S. to pick it up. If I have problems with it I don't want to have to deal with shipping it back to England. I've had a switchlinc controller go bad and that itself was a nightmare. I have to remove the switch, put in a plain switch, ship it back to smarthome and wait for them to fix it. I'll probably be without the switch for a month. It's unfortunate that Smarthome owns Switchlinc, and they won't just swap out the switch for a new one. Now I have to go into the box two times. I wish that they would bill my card for the replacement and credit the card when they get the bad switch back. Imagine how long it would take dealing with England

I don't know if there are any US suppliers of the IR543AH. I understand that the modification has not been submitted for UL approval which could be a barrier to a US company's carrying of the product.

Warren,

Do understand what the IR543AH will and will not do. Generally, you must have a Pronto or Handspring Visor w/Omni Remote in order to use the IR543AH. This is because the original IR format used by the IR543 did not contain a house code at all. The house code that was sent over the power line was gotten from the little house code selector on the top of the IR543 unit. What the folks who made the IR543AH did, was to define their own IR commands for the house codes, that the 543AH would recognize. They provide a Pronto .ccf file with the commands. The upshot of all this, is that the typical IR543 compatible remote, will not work with the IR543AH. For folks that don't own a Pronto or Handspring Visor/Omni Remote, if you know someone who does, you could teach the commands from one of those, to a learning remote. If the IR543AH IR codes are anything like the standard IR543 codes, X-10's 8-in-1 learning remote will not be able to learn them. More capable learning remotes usually do not have a problem there.

As for a U.S. supplier, I think that Home automation net was planning on distributing the IR543AH, in the U.S.

For Larry,

What exactly is the UL approval barrier issue? Is it an insurance thing? Surely there is no law against selling non-UL approved devices, here in the U.S.

I'm just saying that I think US distributors might be reluctant to sell something without UL approval. Maybe not, I don't know.

I have been talking to Laser about carrying them and I am close to making a deal. I am looking into the UL issue. The concern is that it was a UL approved device and they take it apart and do some major modifications. I am trying to get happy with the fact that the mods are to the processor section on the low voltage side. The way lawyers work, if a house burns down because of an X10 switch and they find out that this modified device turned on this switch, you know that lawyer will through me in on the suit even if it has no relationship. I wish I did not have to worry about stuff like this but this is the USA.

If you can solder, you might want to check out BX24-AHT All Housecode Transceiver is at:

Jim,

I just took a quick look but it looked like the BX24-AHT is an RF -> X10 transceiver, not an IR -> X10 one.

I got to thinking about multiple house codes with a standard IR543 and I came up with a pretty easy mod to support 2 house codes. I used a Universal module's relay contacts to modify one bit of the codewheel setting on the IR543. I did lose one unit code on each of the housecodes. I set the Universal module to housecode "I" with unit code set to 10. The IR543's housecode wheel was set to "I". Sending "10" "ON" from the IR remote sends I-10 I-ON, activating the Universal module's relay contacts, shorting the IR543's h2 codewheel contacts. This modifies the IR543's housecode setting from "I" to "G" for all subsequent commands. It's a bit tricky to send the "OFF" command to the Universal module using the IR543 at that point, since the Universal module is still on housecode "I". Defining a CM11A macro to send I-10 I-OFF, when it sees a G-10 G-OFF, solves that problem. So, "10" "ON" from the IR remote, selects one housecode and "10" "OFF" selects the other.

Larry -- you are right of course - thanks for the correction - maybe I should not be posting here when I am half asleep :)

Cheers, Jim.
