There is no software 1.4 for Beomaster 7000....the latest is 1.3 that enables 2 way communication with BL5000/7000
I believe BM7000 was 2-way from the beginning, my unit is software 1.0 (by the sticker on the back and by the sticker on the chip) and it's two-way.
I haven't seen any release notes on what was fixed on the later versions but I believe (based on some older discussions) that it was related to some exotic multi-room setups where some combinations might not work with the earlier software.
Anywhere I could get a file of the 1.3 for BM7000 so I could upgrade?
It is correct that BM7000 was 2way from the beginning...Sw1.3 was a special version that was introduced after the production of the 7000 ended. It has partnumber 8342830,but is no longer available from B&O But a couple of years ago a guy named Ulf from Germany could deliver them, I don’t know If he still has them on stock.
SW1.1 was introduced from serial number 10229486 and corrected some issues with the clock sometimes being reset when the Bm7000 was used as a stand-alone product.
SW1.2 corrected som issues with the date being set wrong when using the Beomaster7000 in combination with a LCS9000/Beolab3500 and A Master Control Panel.... this software was never implemented in production.
