Wireless M-Bus + 2 pulse inputs
(67-00-30) (PCB 5550-1097)
The radio module has been designed to form part of Kamstrup's hand-held Wireless M-Bus Reader
systems, which operate within the unlicensed frequency band in the 868 MHz area.
The module fulfils the C-mode specifications of prEN13757-4 and can thus form part of other systems
using Wireless M-Bus C-mode communication.
The radio module comes with internal antenna and external antenna connection as well as two pulse
inputs
(VA + VB). See paragraph 9.8
Pulse i puts VA a d VB
–
describes how the pulse inputs function.
The Wireless M-Bus radio transmitter is switched off before dispatch from the factory. It switches on
automaticaly when approx. one litre of water has run through meter. The radio transmitter can also
be switched on by making a forced call (keep both front keys activated for approx. 5 sec. until CALL is
displayed).
Kamstrup recommends that an external antenna is mounted on this module if the meter is fitted with
a top module too. This ensures the best possible radio range

Wireless M-Bus (67-00-31) (PCB 5550-1386)
The Wireless M-Bus module has been de
eloped to e i teg ated i a Ope Mete i g “ ste
(OMS)
solution without further configuration, and operates within the unlicensed frequency band in the 868
MHz area.
The communication protocol is T-mode according to OMS specifications: Volume 2: Primary
Communication Version 4.0.2, and the module uses one-way communication, data being
automatically sent from the meter after installation, every 15 minutes from module 67-00-31
The T1 OMS module supports individual encryption and comes with internal antenna as well as MCX
connection for external antenna.
Kamstrup recommends that an external antenna is mounted on this module if the meter is fitted with
a top module too. This ensures the best possible radio range
