synchronized with measuring intervals of superior part of the electrical grid. In this case it is necessary to bring
15-minutes synchro-signal (e.g. from electrometer with such kind of output) to the synchronizing port.
WARNING:
If there are synchronization pulses with inverse logic connected, it could cause a slight decreasing of
battery lifetime (up to 5 %).
”
Inverse logic” means that the input is permanently short-circuited and only during
short time pulses it is released.
Regular broadcasting can be
disabled
by entering of ”periode” command with ”0” parameter. Example:
cfg#periode 0
Periode changed from 60 min. to disabled

Group of
”
power”
(transmitting power),
”
chan”
(frequency channel),
”
mode”
(communication mode) and
”
ekey”
(encryption key) commands is intended for setting of module
RF-subsystem parameters
.
The command
”
Power”
is used for adjusting of the module broadcasting power. Factory setting is 100 mW
(average power). Actual value of the power can be displayed by using of the
”power”
command without parameter.
Transmitting power can be set-up by entering of the number of power level. There are five levels available:
- value ”1” for transmitting power 14 dBm (25 mW)
- value ”2” for transmitting power 17 dBm (50 mW)
- value ”3” for transmitting power 20 dBm (100 mW)
- value ”4” for transmitting power 24 dBm (250 mW)
- value ”5” for transmitting power 27 dBm (500 mW)
An example of checking, setting and re-checking of transmitting power:
cfg#power
MBUS power : 3 (20 dBm)
cfg#power 5
MBUS power changed from 3 to 5 (27 dbm)
cfg#power
MBUS power : 5 (27 dBm)
cfg#
The command
”
Communication mode”
is used for selecting of the module’s communication mode. Factory
setting is N1 (unidirectional), or N2 (bidirectional), actual setting can be checked by using of
”
mode“
command
without parameter. Change of mode can be done by entering of desired option as a parameter of the command.
Communication modes are defined by the Wireless M-BUS standard, accurate choice of relevant communication
modes of the module is stated in the line ”mode” of ”Help” summary (see the paragraph
An example of checking, setting and re-checking of communication mode:
cfg#mode
Mode N1
cfg#mode 2
CC1120 state 0x0f, marcstate 65, fifo tx 0, rx 0
Mode changed from 1 to 2
cfg#mode
Mode N2

The command
”
Frequency channel”
is used for selecting of the module’s radio frequency channel. Frequency
channels for the particular frequency bands are defined by the Wireless M-BUS standard. Actual setting can be
checked by using of
”
chan“
command without parameter. Change of channel can be done by entering of desired
option as a parameter of the command. Accurate choice of relevant broacasting communication modes of the module
is stated in a line ”mode” in ”Help” summary (see the paragraph
An example of checking, setting, saving and re-checking of frequency channel:
