I recently purchased a Philips VL 1200 wireless TV Link and connected up to second TV in bedroom no problem. However, the Infared extender for remote control from the second TV is a different story.
I have tried everything in the instuction booklet, to no avail.

I am trying to remotely control the Panasonic TU-DSB40 digibox.

It says in the booklet that the extender operates on a frequency of 32-40 (hz, If I remember correctly). In digibox setup (0,1, select) the RF output is 60. I changed this to 40 but it didn't make any difference.

If anyone has any ideas that might work I would be greatful to hear from you.


Regards,


Kevin

A little less analogue, and a lot more crap.

Theres no link (sic) between the operating frequency of the wireless remote system and the channel output frequency

At 32-40 Hz it sounds as though the signals would be mains modulated - do both units plug into the electricity sockets ?

Additionally there is something strange about the pulse modulation of the digibox remote controls meaning very few aftermarket remote systems work when used with them (fine with other receivers though) , which is why the TV link system and second modulator output have been very successful - except when used where running another cable is impossible.

Try it on another system first - easiest way would be to take the video upstairs and see if operating the remote downstairs turns it on /off. If it does then you know you are stuffed for the digibox

What was the problem Kleefarr, might be useful for someone else if they experience the same difficulties. :)

I discovered that the IR worked simply by turning the VL1200 transmitter around and facing it head on to the Digibox. Having discovered that this worked I knew it was simply a case of the sensor not picking up the signal.
It stated in the instruction book "Slowly move the IR eye along the front of the panel of the video source" Distance not exceeding 1 cm. When I originally tested it, I was running IR eye about half a cm away.
This time I ran it along while it was actually making contact and voila!
The signal must have been quite weak as it wouldn't work any further than a few mm's away.
Just me not being precise enough I guess.

Anyway, happy as Larry now.... Early night me thinks.... channel hopping in bed!! 8)
C u soon

Nite nite,
