Wiring Beolab 8000 & Beosound 9000

Dear Members

I am very new to B&O World.

I am facing a pre-wired installation where the cables are not distributed as originally shown in to the B&O notices (Going from one device to the other), and cables are Cat6.

Before making any mistake by making a wrong connection between 4 Beolab 8000 and a Besound 9000 that could harm equipment, i would like advice.

 

Is this possible to wire this way ?

(see original diagram: https://docs.google.com/file/d/0B0-vuGXKi2g1U1BDcFVBbWtScjA/edit)

All devices are connected (via Cat6) to a junction box.

If possible, please advice for how to wire the cables to the 8 pins DIN Connectors (Connector shown on diagram from the inside (soldering face) - not sure if the numbers 1 to 8 on the connector are correct)

Best Regards

Alexandre.

Dear Søren

 

First, thank you very much for you prompt reply.

I tried to wire according as much as possible to the diagram you sent me. (considering i have cat6 cable instead of what is mentioned on your diagram)

I wired 2 Beolab 8000 with the beosound, (see numbers on the attached schema), it did not work. Later i made a straight cable according to my wiring between one beolab and the beosound (without going throught the junction box) it worked.

Would have any comments to my schema, where could it be wrong ?

regards, Alexandre

Are you sure the junction box "switches" all the wires one for one ? i.e. no transpositions and no drop offs ?

Have you used a multimeter to test that electrical signals are correctly carried from each pin through the switch to the correct pin at the other end ?

And my eyes are not good enough to read the blurry photo of where you have the switches on the BL 8000s ?

Dear Elephant

Following your advice, i have done a re check of each pair of the Cat6 cables.

No drop offs, no inversion, no short circuit.

You ca download the file, it is a good definition, if it is not enough i cans send it to you b y mail in pdf.

I am considering may be that somewhere i should wire the connectors in a different way for the shield wires maybe.

I also discovered that now B&O provides cables with RJ45 connector on one side and 8 pin DIN on the other side, maybe i should buy one and look how did they wire it.

 

Best regards.

Hi Alexandre,

Can you test the two cables end to end through the connection with the switch ?
