Hi,

I have installed a DS02 doorstation connected to comfort with the DM02. The ringer, and door opening is working fine, but I can\'t communicate to the door station, there is no MIC or SPEAKER. 

Anything to be configured or maybe a cable problem?

Check the wiring according to the DM02 manual, download from https://www.cytech.biz/dm02_manual.html?category_id=108
There is a wiring diagram for DM02 to DS02

Also check that the Mic and speaker are connected to DP MIC and SPKR on Comfort, and not the KP MIC and SPKR

It\'s OK,

my mistake, I didn\'t connect the DM02 to the Comfort...

Ths,
RR

Thats normally the case

How did you connect dm02 to comfort ? Using which wires ?
