6.2.2. Network function (M51)
Requirements for connecting over a IPv4 network.
To automatically identify the IP configuration of a data logger (which has received
an IP address in the IP network via DHCP for example), it is necessary that UDP
broadcasts are allowed through the network.
b
Note: Based on their concept, UDP broadcasts do not operate
through a router (NAT), but instead only within its own network.
If the data logger is outside of the network, using fixed IP addresses through
a system administrator is highly recommended.
Connect to the network
If the data logger is connected to a local network and the network function is
activated, then software configuration and data reading from the data logger
can be carried out over the network.
A signal which is broadcast from the data logger over UDP allows the SmartGraph
software to automatically find the measuring device in the local network.
The first time that the data logger is connected to the network (add network
device), it may be necessary to adjust the data logger's network settings to the
configuration of the available network in the SmartGraph software. The factory
preset is DHCP.
Further information about the network function is provided in the software
manual which you can open from the help function of the SmartGraph
software.
With the professional version of the SmartGraph software, it is also possible to
retrieve and log current and saved measured values of the data logger in
adjustable request intervals over the network.
Use in network mode
For continuous use of the network card, the data logger must be mounted on a
wall. There must be a free air convection within a gap of a half metre and the
zone must not be interrupted by external sources of convection (fans, lighting
etc.).
Power supply in network mode
Using the network card, which is built into the data logger, raises the power
consumption of the measuring device.
When the device is running on batteries alone and not connected to an external
power supply, it automatically deactivates the network function after 12 minutes
pass without communicating with the network. In this case, the network function
must be restarted by an external power supply either manually or automatically.
b
When using the data logger in LAN mode, the power should thus
be supplied by the USB power supply.
In the optionally available PoE design, the data logger can have its power
supplied directly over the network connection.

Information for system administrators
Broadcast over UDP:
PC sends to ....................................UDP:255.255.255.255:52010
(data logger receives at UDP port 52010*)
data logger replies to ......................UDP:255.255.255.255:52005
(PC receives at UDP port 52005*)
Data transmission over TCP:
data logger receives at TCP port 52015*
* The ports can be reconfigured, but this is not recommended.
Open or lost TCP connections are closed by the data logger after a TCP timeout
of 120 seconds.
6.2.3. Factory settings (M52)
This function resets the device settings
to factory settings.
Even when resetting the device to factory
settings or when there are no batteries
in the device, the measurement data re-
mains in the memory and is not deleted.
Information about deleting the mea-
sured data is provided in chapter 9.2.
6.2.4. Acoustic function (M53)
Activating or deactivating the acoustic function switches the data logger’s acous-
tic signal either on or off. If the acoustic function is active, the function’s display
symbol is shown on the display.
When the acoustic function is active, alarm results are indicated as a tone, pro-
vided an active alarm has been preset for one or more of the three display mea-
sured values in the SmartGraph software.
If the acoustic function is not active, then none of the navigations steps which
require the mode selection button on the data logger to be pressed are acknowl-
edged by a tone. The same applies for selecting a mode. If no selection is
made, and thus the setting level is exited, then a tone is also emitted.
