Hello,
This may be a harsh question, but some of our customers don't like the look of the Fermax Door Stations. Instead, they would like to use a Busch-Jaeger Welcome8 Door Station (I agree with them, I think it looks very neat
http://en.red-dot.org/pdf/11-2585-2012-2.jpg
The problem is that this Door Station is digital and uses a proprietary bus.
BJ do offer an "IP Gateway" to their ComfortPanel touch screen system, but this may use a proprietary protocol too (if we could access the digital data through IP, we might develop a SIP to analog interface to Comfort, but this looks difficult as the data may be encrypted/proprietary).
The other solution would be to use the Busch-Jaeger housing but replace some component in the BJ Door Station with analog friendly components (Mic/Speaker/Camera).
This will off course result in a higher price (need for BJ door station + extra hardware) but this could work.
We are looking for some guidance and hints in order to cleanly replace the mic/speaker and push button internal parts of the BJ doorstation so that they can be used with comfort (we wont discuss the video part here as it has nothing to do with comfort).
Option A : Use Fermax skyline (conventional 4+n) audio module + push button module, disassemble them and mount the Fermax electronics in the BJ housing
Option B : Buy "cheaper" single components (one mic, one speaker, but we want high quality hardware though) and interface them with Comfort.
For the B option, we don't know when components could be used. Can any speaker be connected directly to the Comfort DM02 (same question for microphone) ? Do we need additional electronics between the speaker and the DM02 ?
Would it maybe be "easy" to directly hook the busch-jeager mic & speaker to the DM02, bypassing the BJ electronics (no need for other electronic ? Speaker/mic direct hook to DM02 ?) ??
I know this may sound overkill, but the look is a matter of taste, and this is important to some of our customers.
Besides this thread could help other people wanting to use digital door stations with comfort by modding them to analog.
Any help, opinion or hint is welcome ! :-)
Thanks !

You cannot connect a mic and speaker directly to the DM02, the signals need amplification
We have a little known product called DP03X which is a DP03 but for connection to DM02 instead of direct to Comfort Bus
Hence you could use the PCB from this product and attempt to connect it to the mic and speaker of the BJ
The DP03X manual is attached

The DP03X is no longer available so I cannot get hold of one to canabalise it.
I have canalbalised a very small door station and wired everything up directly video, speaker mic and bell to a DM02, as per the manual I realised that you cannot directly connect speakers or mic that way. I am trying to find an alternative way of connecting the speker and mic.
Also I have found dificulty in getting the door station to ring on the keypads ect it has been set with jumpers to 0 volt is there something that I am missing as I cannot find further instructions on this, the door bell has been wired to DM02 bell & grnd, when you press switch on DMo2 the keypad responds to action (KT03)
Any assistance on this would be appreciated
