Data communication
The meter has built
-in radio for Wireless M-Bus Mode C1 or T1 OMS (one-way data transmission from
meter, no data receipt in meter)
.
13.1
Transmission
Data packets are sent at intervals of approx. 16 or 96
seconds. Every eights packet is a full data string,
whereas the 7 intervening packets are compact data strings.
Please note: The contents of the data packet is updated every time a full data string is sent and the first
time a compact string is sent after a full string.
13.2
RADIO OFF
Radio transmission has been interrupted if ‘RADIO OFF’ is displayed.
RADIO OFF is activated at the end of the production process at Kamstrup. The meter removes RADIO OFF
automatically when the volume register has counted water consumption for approx. 5 seconds.
RADIO OFF is intended for situa
tions where radio transmission is inappropriate
–
e.g. in laboratories, in
warehouses and during air transport, where many meters will typically be concentrated in one place.
It is not possible to stop the radio transmission of a meter in normal operation permanently, but the meter
can be turned OFF by means of the optical eye e.g. in advance of air transport. However, the radio will
automatically turn ON again, as soon as a wa
ter flow is registered.
RADIO OFF secures that the meter does not send radio communication until the meter is put into
operation for the first time.
