Hello Martin,

Beovision 7 has 4 IR outputs, each one can control one connected device.  Hence, if you have several devices connected to one HDMI input on the TV, the TV will only be able to control one of these devices (once the details of the device to be controlled have been loaded into the PUC table of the TV by your B&O dealer).

Hence, the TV won't know that it has an HDMI switcher connected.  The best option may be to set the HDMI switcher to automatic if possible (ie. let it switch to whichever input is active) and then set the IR output of the TV to control the connected device that you use the most often.

This cable will give you control of an external device via the C1-C4 outputs of the TV:

Hello,

I connected a gefen hdmi switcher to my BV7-40 MKII SW7.94, but changing the hdmi inputs via PUC does no work.

On which connector (C1-4) must the ir-emitter be connected to get hdmi source switching via PUC ?

 

Martin

according to:

C4.

Thanks Stefan,

I assumed that Martin didn't have the newer Beovision 7 software with the "HDMI Expander" option in his TV menu, maybe I should have asked!

Kind regards, Steve.

Thank you both for your answers. I will give it a try this evening.

Martin

Ok, tested it on C4, but it didn't work.

Will try another Gefen HDMI switcher tommorow. It's a 3x1 switcher only, but for testing it should make no difference with only 2 sources.

These Gefen switchers do have an extra connector for an ir extender cable. Might it be possible to make a direct connection between the TV and the switcher without ir ? Just to be sure the ir receiver in the switcher is not defective.

No, it was a used one without the remote control. It's hard to get these switchers for a reasonable price anyway.

Maybe I can learn existing remote control codes from my lintronic box to a Logitech remote to test the switcher's ir receiver.

Even checked that the ir receiver is in default mode on the switcher.

Martin

Did you read the linked site?

"place the IR eye 5 mm beneath the IR receiver or use a thin piece of paper between eye and receiver, otherwise it can result in malfunction.

Maybe worth a try...

Stefan

Will try it this evening, but have little hope that it will work. I had the ir emitter 3-4cm away yesterday.
