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 setup.
In order to change a parameter option, you simply need to select or
unselect the corresponding check box. The following options are
available:
- Use the Device ID (editable) text box to distinguish the HMT
transmitter. For information on how to change the device ID, see
Vaisala HUMICAP® Humidity and Temperature Transmitter
Series HMT330 User's Guide.
- Select the Mode in which the HMT transmitter is operated. When
you select the Cyclic transmit mode, the transmitter automatically
sends data at predefined intervals. If you select the Polled mode,
the QML logger polls the transmitter at predefined intervals to
retrieve data.
- In the Polled mode, by using the Timeout parameter you can
define the maximum length of time allowed for the HMT
transmitter to reply.
- In the Cyclic transmit mode, with the communication timeout
parameters you can define a maximum interval between two
messages. If the new message from the HMT transmitter has not
been received within the given time, the data in that message is
then marked as invalid.
