Why can't the OUTMM be found in CSMconfig?

If the bitrate of the OUTMM is adjusted CSMconfig cannot find the module despite activated bitrate detection in the settings. The OUTMM is completly passive.
If bitrate detection is activated CSMconfig only listens on which bitrate meanigful information is delivered. Since the OUTMM does not send anything CSMconfig cannot recognize the bitrate and does not find the module.
