The setting "UDP port" is intended for fast data transfer via UDP. See also chapter 5.4.3. The default
port for data transmission is 4649.
It is possible to retrieve the current values of the Ser[LOG] in tabular form via the network interface via
HTTP. For this purpose, a corresponding port must be entered in the field "WEB http Port". By default,
port 80 is used for this purpose. Port 80 is the official standard port for http communication and therefore
does not have to be specified when you call it up in the browser. If the IP address of the Ser[LOG] is
called via the browser when the function is activated, a simple table with the measured instantaneous
values is displayed. The function is limited to one user. Multiple parallel calls of the current value page
are not possible.
Make a note of the network settings for later communication.
5.3.4.2 Communication via serial interface RS232 / RS485 / RS422
In the "Serial interface" frame, the baud rate and handshake for serial communication are set. Commu-
nication is via the SNAP protocol. Communication is always carried out with 8 data bits, 1 stop bit and
without parity (None). The "Connection type" selection list determines whether communication is carried
out via a direct connection (online) or via a dial-up modem connection (modem). For communication via
the serial interface, the selection must be set to "Online" (direct connection).
To use the communication via serial interface, the used interface must be activated and set to SNAP
protocol. To do this, switch to the "Interfaces" tab of the configuration window and activate the COM
interface to be used via the "Power ON" checkbox in the respective frame. It is recommended to use
one of the interfaces COM1 to COM4 for communication, as COM5 and COM6 have special functions
for connecting SDI-12 sensors or AnDiModules.
Set the SNAP protocol for the selected interface under "Protocols". The communication parameters
"Data Bits","Stop Bits" and "Parity" are automatically set to 8 data bits, 1 stop bit and no parity (None).
Do not change these settings!
Note: Please note that communication between the PC and the Ser[LOG] is always carried out via the
SNAP protocol with 8 data bits, 1 stop bit and without parity (None).
If necessary, make the settings for "Handshake" and the baud rate (Baud). The settings for handshake
and baud rate must match those in the "General" tab of the "Serial Interface" frame.
Note the settings for later communication.
5.3.5 Configuration of the sensors
The Ser[LOG]-Commander offers an extensive library of preconfigured sensors from the LAMBRECHT
meteo product portfolio. The sensor library can be extended by the user with own sensors.
The measurement channels are assigned via the "Measurement channels 1...40" and "Measurement
channels 41...60" registers. The appearance of the respective registers depends on the number of
AnDiMod used. A total of 60 channels can be defined. They differ in analog, digital status and serial/vir-
tual channels. A "sensor" always represents one measured value per measurement channel.
The number of available channels depends on the number of AnDiMod used.
