I have old board which I was trying to replace because LP51,LP52 have blown and I figured I might as well upgrade the board instead of messing about with soldering. However half-way through I noticed that the DP connection for MIC/Voice is not present on the new board (or I can't see it). The old board has a door phone module connected to a Fermax door entry system. Is there a way to connect the new board or is there something else I need to do?
Thanks, that explains the differences. How can I find my exact board model. On the DSI01 page on this forum the CM9001 board has a switch, K51, which needs to be set when installing the DSI01, however my board does not have this switch. I purchased the board just a couple of months ago.
