RE: IR7243AH's - SUCCESS not the CCFs

[Craig Callander <craig@xxxxxxx>]

Its not IR interference. I tried both in day light and complete darkness last night. I tried a few inches away, off the walls, directly, with IR7243AH vertical, horizontal, upside down, above TV, below TV,.............Same results every time.

 

I cant explain it, but my IR7243 doesnt send X10 on/off commands via IR if it is near my TV and Sky Digital cable, even if TV and Skybox are disconnected from mains. Strange but true.

 

Maybe someone else that DID have problems can reproduce this??

Again that's strange as mine quite happily sits on the TV - in fact it works happily anywhere that I put it. I'd have thought more likely is a source of IR interference ... strong sunlight or fluorescent light are two possible causes.

 

Ultimately I have found that the All Housecode IR receivers have been 100% reliable for me.

 

The test X10 codes that I sent over worked fine however I found that for absolute reliability I needed a 0.1 second delay between sending house/unit codes and command (ON/OFF/DIM/BRIGHT) - this ties in pretty much with what I found when I first tried these devices.

I have found the problem with my IR7243AH not responding t ON/OFF/DIM-/+ commands...

 

It does not like t be placed near TV (metal??) and/or RF cables, esp Sky Digital.

 

I found this out last night. I went upstairs t download files (Thanks again Phil/Mark!!!) t prono via PC, and I took the IR7243AH with me. It worked with my original CCFs 100%....

 

mmm..

 

S I took it down stairs again, placed on the floor, plugged in t same socket as I was experiencing problems, and it worked 100%....

 

mmm...

 

I placed back on TV stand, it then stopped resonding t ON/OFF/DIM-/+ commands via IR, buttons on top work fine. So I unplugged TV and Digi box from mains, still not working.

 

mmm..

 

Unplugged Sky cable/UHF Ariel/and bedroom feed and it worked 50% of the time.

If I move it away from TV, it works 100% of time.

 

Why is this IR device sensitive t Sky/RF cables?? My sky is cable is CT100, but UHF is cheapo brown stuff.

 

Can the others who had problems try moving their IR7243AH, and someone who does not have a problem move it near their unplugged TV and/or RF cables??? This may explain why some people have managed t get this device t work in some mains sockets and not others??

Has anyone had any luck with their IR7243AH's using the CCF that Mark put up
on the files area for me?
