Current state – displays the current parameters of the device - the internal temperature
of the device and the battery level.
M-BUS settings – allows to setting M-BUS interface, set the model and addresses of
connected heat meters. M-BUS-1 uses the secondary addresses for poll of the connected
devices. The secondary address usually is equal to meter serial number.
Data transmission settings – a group of parameters that allows you to configure the
collection and transmission periods, and the time zone for the internal clock of the device will
be set which. The readings are read from the connected device at 00.00 on the internal clock of
the device if the data collection period is set to 24 hours, at 00.00 and at 12.00, if the period is
12 hours and so on. All readings are stored in the device memory until the next communication
session.
The data transfer period can be adjusted from 5 minutes to 24 hours. Data transfer is
carried out by a random time at the selected period. At the next communication session, the
device starts sending accumulated packets with readings, from the earliest to the latest.
With the "Confirmed uplinks" option turned on, the device will send the next packet only
after receiving a confirmation of the delivery of the previous one. If such confirmation has not
received after the fulfilled in the settings uplink number of transmissions, device completes the
communication session until the next one according to the schedule. In this case, the device
continues to collect data according to the data collection period and store it in memory. Non-
transmitted packets remain in the device memory until the next communication session.
With the "Confirmed uplinks" option turned off, the device just sends all accumulated
packets to the network in order from the earliest to the latest. There are no checks of package
delivery in this mode. There are no non-transmitted messages in the device memory.
Commands – allows transferring the command "Poll connected meters" on the
converter. The converter polls all the connected devices.
