M-Bus module 66-0P contains further M-Bus functionality. In addition to primary addressing it also supports
secondary and enhanced secondary addressing as well as wildcard search and collision detection. Via the M-Bus
network it is possible to reprogram customer numbers, date/time and the pulse inputs In-A and In-B.
The M-Bus modules have two sets of parallel M-Bus terminals marked 24 and 25, to which the M-Bus can be
connected. The M-Bus connection is independent of polarity.
The M-Bus modules are galvanically separated from the meter and is supplied via the M-Bus.
Each M-Bus module has a power consumption of 1.5 mA (1 Unit Load)
The data transmission speeds are 300 or 2400 baud and both M-Bus modules have a built-in autodetection of
the baud rate.
The pulse inputs on these modules are identical with the ones described earlier.
The Kamstrup M-Bus system is designed to meet the demands in the EN 1434-3 standard.
For further information, see the Technical Description for Kamstrup’s M-Bus system (5511-710), and Technical
Description for M-Bus module 66-0P (5512-243).

The radio module is used for wireless reading of MULTICAL
®
401.
During installation the radio module retrieves the type and meter number of the meter and transfers data to the
memory of the module.
The radio module is ready to communicate in less than 10 seconds.
The radio module is supplied as standard with internal antenna.
The radio module can be read via the hand-held terminal MULTITERM, but it is also prepared to form part of a
radio network.
The pulse inputs on this module are identical with the ones previously described.
The radio system is designed to meet the requirements in the EN 300 220 and EN 301 489 standards as well as
the R&TTE directive (
R adio & T ele T erminal E quipment).
