There are several parameter options you can set in the
Communications frame of the Measurements view. Note that in
general, the predefined settings are the most suitable for a typical QML
logger setup.
In order to change a parameter option, you simply need to select the
corresponding check box or remove its selection. The options you select
must be enabled in the connected weather transmitter.
The following options are available:
Use the Device ID editable text box to distinguish the weather
transmitter. For information on how to change the device ID, see
Vaisala Weather Transmitter WXT520 User’s Guide.
You can select the Mode in which the weather transmitter is operated.
When you select the Cyclic transmit mode, the weather transmitter
automatically sends data at predefined intervals. This mode can be used
if only one weather transmitter is connected to the same serial line (only
one device per serial port is allowed). If you select the Polled mode, the
QML logger polls the transmitter at predefined intervals to retrieve data.
Several devices can be connected to the same serial line.

NOTE The options you select must be enabled in the connected weather
transmitter.
