6. M-Bus module
The EDC-module as M-Bus module is used for inte-
gration of water meters in wired M-Bus networks.
The EDC-M-Bus module which is mounted on the
water meter enables the reading of the water meter
via Bus.

* Reverse pulses are reduced by the corresponding number
of forward pulses. Function of the pulse modules output
according to ISO 22158
The adjustment of the modes is possible with the
ZENNER-MSS Software by use of a ZENNER
MinoConnect bluetooth or USB and the combined
ZENNER IrDA optical. Alternatively, the ZENNER
Device Manager Basic app can be used instead of the
MSS software.
8. Combined M-Bus and pulse module
The combined M-Bus and pulse module has been
developed specifically to enable the simultaneous
readout by two different users. In this case the pulse
version will be delivered by standard as Mode
