Tried again. Just for good measure I also replaced the DS02 mic. Still the same. All wires have been tested for continuity. I\'ve got to say, this sounds more like a software issue to me. Working to begin with. A few updates later, no longer working, no changes to wiring.
Though as I said, I can\'t pinpoint when it stopped working, it may have been prior to the previous versions. Previous versions before that were the older update method though, so don\'t want to go back to those.
You can change the firmware to ULT 6.005 using the attached file to test if it has any effect on the DP02 audio which I doubt. You can always upgrade again
Do not downgrade the Ethernet as this should not have anythng to do with the door station, it is just for programming
No luck. Really would like to try to isolate either the dm02 or ds02 before returning it. I have a spare mic now from the ds02. Would it work to wire the spare mic itself directly to the voice/mic inout on dm02 (ireplacing ds02 input) and test the mic input to the phones that way? If so how would i wire? The Mic has two wires, + and -
No the DS02 mic cannot be connected to the DM02 MIC, it has to go through the DS02 amplifier
Do you have another spund source that you can connect to the DS02 MIC. Remember this is the connecyion labbeled \"To DOOR \" MIC JP7
You cam also try removing the wire from JP6 SPK IN (from Comfort) and connecting it to JP7 MIC. This connects the voice from Comfort to DM02 and connects it to MIC IN (from DS02) so that when you talk to the Door station, the voice is actually not going to the DS02 but will be fed into the DM02 MIC instead of the DS02 Mic so you can hear it at the other end
I hope this is not too confusing
I was able to borrow a dm02 and ds02 and have isolated the issue to the dm02. Borrowed dm02 works fine. Ive checked the connections and terminals and any obvious breaks on the dm02 itself. Externally all looks good, the mic input just seems to have stopped working. It\'s out of warranty unfortunately.
*(Thanks again Nigel, you have been a massive help here.)*
I am glad the problem has been identified
Please return it to whoever you bought the DM02 from so we can check what happened
Unles there is any damage we should not be charging for the repairs
