Which IR eye for the Beolink Passive?
12 replies
Hi Everybody,
I've a Beolink Passive and MCL/ML black boxes.
Following Guy's successful IR eyes genetic crossing experiences, I've found for cheap a complete MCL2A with boxe, IR eye, papers and wires in the hope of making the Passive standalone.

The IR eye has 5 wires: brown, grey, yellow, white and green and I plug them in the IR ir of the black box like in these document:

But nothing happens by IR or by pressing the mute button. The Beolink Passive is just connected to Power and IR.
Should it have speakers and input to start (not talking about Powerlink Trigger here)?
Do I miss something?
Or is it just that this eye do not work with the Passive?
Is it any way to check that the IR eye is not faulty.
Bonus question: when is the Masterlink socket used in these boxes, seem like every time somebody want to use them the answer is "find yourself a fully wired PL cable".
Thanks.
Interesting project!
I think that your IR eye wiring may be incorrect:
- On the MCL2A transceiver the Green wire is for +5v. (Green became IR data in later devices, such as BS3 sensor)
- I think that the White wire is IR data (but if that doesn't work, try Yellow!)
- Brown is indeed Ground

Thank you Guy for this two answer.
That' full of hope and i'll try all this as soon as possible.
About the passive in Masterlink configuration, is it possible to feed the box throut Masterlink (I know they are Line in/out wires…) or does the masterlink need some sort of handshake protocol or trigger current to start.
My goal is to have a standalone thing made of amplification with the passive, control with the eye (on/off, volume, bass, treble) and speakers.

This what I tried:
Connectig the green to +5V (from computer USB) and brown to 0V. Played with the remote. Nothing. That IR eye came with a second board declared as faulty. Tried the same. Nothing.

Then tried to wire the eye to the Passive as Guy suggest. Nothing.
The Passive is still not connected to anything beyond power and IR.

Thanks again Guy,
My further investigations: as I have a Beocenter 7700 I tried to use the MCL2A as it was intended. Beocenter has no speakers at all. Speaker ribbon from speaker 1 or 2 (didnt change anything) to the white box and there, IR eye hard wired and beovox connected.
On the eye. The red light glows when receiving IR and according with the press of the key.
The Mute key do bring music on ad off on the speakers.
A long press doesn't put the Beocenter on standby or a simple one doesn't bring it to life.
Volume commands through IR are received (led blinks) but no effect whatsoever.
The faulty IR board do light up the mute led but doesn't react to IR (capacitor ?). When you touch the little pins that must be the socket for the keyboard I guess, the relay does click in and out and de mute led light accordingly…
