Re: help needed with the reviving of a BM7000 external ir "sensor "

Hi forum ,

The sensor is working , with help of nick who handed over valuable information.

the thing to keep in mind is , that the 8 volt supply to the external sensor has to be wired-in , CP1 has to be connected to 8 volt otherwise there is no supply going into the sensor.

8 volt can be found on the display/front pcb pin 4 of connector P11 .

sensor schematics are here ;

Most likely it is all the same sensor 5500 , 6500 and 7000 .

The connection on the bm has been dropped on the 6500 and 7000 , but was available as an upgrade-kit for these units.

i have put in the cable conn 98 on the processor pcb , and measured the 4 lines and do think there is smoething wrong .

so now it is time to measure , ...................

If someone has the schematics , that would be of great help.

Looks the same as the sensor for the Beomaster 5500?

Thanks for your help ,

In fact i was looking for the schematics of the complete device .

see picture .

Is there someone who has the installation description for this "sensor"-kit ( 8087018 )

It's just a diode... BPW 82

There is also a datasheet available.
