I belive there used to be a servicemanual for the Beolink Passive in the manual library on Beoworld.

However there seems to be an issue accesing the product pages to check right now. I have made a post to Multicare about that issue.

If the manual is not shown in the library when it is active again try reaching out to Multicare and ask for the manual, as there is still a lot of manuals not uploaded to the library

Sorry but I can only help with very simple faults, but if you post more details of the fault that you are finding then others may be able to help.  The pictures that you have attached are not very clear, in that I am not sure what you are trying to show.

Hve you tried to measure the voltage where you have noted “on”. There should only be voltage there if a Powerlink cable is connected and activated from at Beosystem

that is the problem , with only 220v connecet , it is on , the power up is high on p200 pin 8 , and when i connect 5v to

pin 1 on powerlink scoket , p200 pin 8 goes low. p200 pin 1 is connecet to on/off switch when i press it it goes low and when

i relece it it goes high .it looks as it is the oppesit as it should be.

tager lang tid at skrive på engelsk.

I have tried to open one of my passives and did some measurements to compare.

One important thing to note.The button on the front is not and on/off button but an off button. If I activate the passive from a B&O musicsystem via Powerlink I can press the button and turn the Passive off, but I cannot turn it on again with the button. On the front of mine it is also named OFF.

This is also how mine reacts, so this should be normal behavior, and also how I think it should work based on the schematic.

The same reaction I see on mine. Also note my comment regarding the button function.

I am a little confused here. Based on your earlier thread https://forum.beoworld.org/forums/topic/beolink-passiv-always-on/#post-65711 I though that the issue was that the Beolink Passive was allways on, but now it sound like you can not get it to turn on after all. Am I misunderstanding something?

first with powerlink cable

Are you using af fully wired MK2 Powerlink cable? The Beolink passive is activated by 5V on pin 1 in the Powerlink cable and only the fully wired MK2 Powerlink cable has this as mentioned by Guy in this post in your earlier thread https://forum.beoworld.org/forums/topic/beolink-passiv-always-on/#post-65687

What have you connected to the Passive in this setup? With Masterlink connection it is intended to be used as a link room, thus you will need and IR eye connected to the Passive to turn it on. Also it might be nessecary to do some option settings with the remote on the BS4 and the Passive in this setup.

sorry the passive is on all the time can not turn it off ,   it is the ic 305 that is controling the input from powerlink or masterlink , that is

stopping the signal. or it is mutedet .     when i connect powerlink MK2 , there is 12v on pin 1.  i connecede masterlink to see if there whas

any differens.

Ok I see. I might be worth to look if the mute signal from the Microcomputer changes when the Powerlink pin 1 is active (12V) and inactive (0V), and if it goes all the way to pin 9 on IC305

Location: Denmark

[ballingfisker]

there is no change with or without powerlink . pushing the small off button and p 200 pin 1 goes low

but there is no change at st.by out from microcomputer p 200 pin 14.
