M-Bus Master modules
The modules are easily mounted in the
M-Bus Master bracket.
M-Bus Modem module
To be mounted in the M-Bus Master and
connected to a standard PSTN telephone
line.
The M-Bus Modem is a self-dial modem.
When it calls up, it establishes a open
communication line between the station’s
PC and the M-Bus system. It is thereby
possible to carry out remote reading of
a complete M-Bus system.
After installation, the modem must be
activated with a forced call. Press both
buttons on the M-Bus Master for at least
10 seconds – until “Call” is displayed.
Please contact Kamstrup A/S for further
information.
