11.1.9
Wireless M-Bus + 2 pulse inputs
(67-00-30) (67-00-35) (PCB - 5550-1097 / -1200)
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 EN13757-4:2013 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)
Paragraph 7.3 “Pulse inputs VA and VB” describes how the pulse inputs function.
11.1.10
Wireless M-Bus (67-00-31) (PCB 5550-1386)
The Wireless M-Bus module has been developed to be integrated in an ”Open Metering System” (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 recommend 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.

11.1.11
Wireless M-Bus (67-00-38) (PCB 5550-1356)
This Wireless M-Bus module has been specifically developed for integration in a Wireless M-Bus network (Radio
Link/READy Network) and operates within the unlicensed frequency band in the 868 MHz area.
The communication protocol is C-mode according to the standard EN13757-4, and the module uses one-way
communication. After installation, data is automatically sent from the meter every 96 seconds.
The Wireless M-Bus module for fixed network supports individual encryption and comes with internal antenna as
well as MCX connection for external antenna.
Kamstrup recommend 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.
