MULTICAL® 803
Kamstrup A/S · Technical description · 5512-2360_A1_GB_02.2019
11.4.3 M-Bus + pulse inputs (type no.: HC-003-20)
The M-Bus module is supplied through the M-Bus network and is thus independent of the calculator’s internal
supply. Two-way communication between M-Bus and the calculator takes place via a digital isolator, which gives
galvanic separation between M-Bus and meter.
The module supports both primary, secondary and enhanced secondary addressing. The module can communicate
at communication speeds of 300, 2400, 9600 or 19200 baud and automatically detects the speed used.
The output data package can be configured to include various register combinations by means of METERTOOL HCW
and READy.
The module is equipped with two sets of connection terminals for connection to the M-Bus network. The M-Bus
cable can thus be looped through the calculator so that the use of sockets is avoided. The connection is independent
of polarity. The M-Bus cable must be twisted-pair copper cable. Max copper thickness is 1.5 mm
