Hi,

Connect the VR 1 to the TV-set using a fully specified 21/21-pin
A/V cable (RGB cable).

Selecting option on the TV-set

The TV-set must be equipped with a Datalink module MK2.
If a Datalink module MK1 is built into the TV-set, replace

positions:

If no Datalink module is built in, modify the TV-set as follows.

8003780. If the TV-set is equipped with a Datalink module, it
is indicated by a sticker marked DATALINK on the rear panel.

Yes indeed.

Thank you Ignace, for checking the PCG.

There is no datalink sticker on the TV-set, it is a type 3442 and the whiteline edition. For me, it would be to advanced to update the set to datalink mk 2 as stated in the PCG printout.

See below

I have a VX5000 which I want to connect to Beovision 7-40, but find I'm unable to display the VX5000 menu's etc. all it will do is play or stop (and standby).

I'm told a VX sensor is the answer, any idea how much these are or does anybody have one for sale?
