I bought a Beogram 5500 turntable to integrate with my Beomaster 5000 + MCP 5000. It replaces a TX because that table can’t be controlled by the system.

The Beogram is connected with the 7din cable, and while I can hear sound from a record playing, the TT doesn’t respond to any key presses on either the Beomaster or MCP.  Kinda defeats the purpose!

Any idea why it’s not talking with the other components?

You know about the 7-pin connector. It would be possible that the core is broken or the solder is broken. Or it's not connected at all.

Hi,

If, in fact, you do have all 7 pins in the BG5500 plug, I think there may be another problem.  If I recall correctly, the BM5000 uses MCL82 which is not compatible with the later MCL protocol. The datalink commands are not the same between the two different systems.  I think the MCL82 in the BM5000 was only used in that series and 1 TV from the era, but was replaced by the MCL used in the 5500/6500/7000, plus a number of other systems.

A Beogram 5000 or 5005 will work with the BM5000, or a BM5500 and up will work with the Beogram 5500.

Good luck,

Bill

The datalink commands are the same.
Beogram 5500 should work fine with Beomaster 5000.
If all 7 pins are in the Beograms DIN plug, and the plug is inserted into the Phono socket (many owners put it in a wrong socket), the problem must be elsewhere. There are some protective diodes and, as mentioned above, a broken lead inside the DIN could also be the cause.
