I got the IR converter kit but I still need a powersupply (might have one that can be used) and a cable with a blue LED on it.
If you look at the manual for the code converter you will notice that just to use the Beolink 1000/beo4 instead of the terminal you need to use tape 2 out to AUX in order to make it work. The remote signal goes from the blue LED to the IR reciver box and the tranciver to the IR reciver box.
NOTICE! for the Beomaster 6000 it needs to be modified a bit acording to the manual.
Now that's with the IR code converter kit. If you can do it without is the question. You will need to operate the BM6000/8000 manually.
To hook a newer Beovision to it must follow the basics which is a 1611 converter to AUX and then to Beosystem of choice.
I'm not giving up on my IR converter box as yet. The main trouble for me is the fact if I want to use MCL82 links I need to locate a Beolab kit which has to be used in the setup. Just as rare as IR code converter I guess. I haver never seen a picture of one either.
To do the linking around the flat I got a Beosystem 6500 which is so much easy to locate X tra speaker kits for.
