5. Operation
5.1 Transmitter Start-up
When the transmitter is connected to power supply, there is a delay of 2 seconds as the
transmitter starts up. After the start-up is complete, the measurement data is available from
the analog output and serial line.
If serial line output is used, note that the transmitter will behave according to the configured
serial mode:
• In STOP mode, the transmitter outputs the transmitter model and software version. This is
the default mode.
• In RUN mode a measurement output starts immediately.
• In POLL mode the transmitter does not output anything after power-up.
• In MODBUS mode, the device does not output anything after power-up.

5.2 Vaisala Insight Software
You can use Vaisala Insight PC software to check and configure DMT143 transmitters
intuitively, without typing any serial commands. The software guides you when changing the
settings on the transmitter. The transmitter can be connected to Insight software using a
Vaisala USB cable for computer connection (order code 219690).
With the Insight software, you can:
• See device information and status.
• See real-time measurement.
• Configure serial communication settings, filtering factor, alarm LED, and analog output
parameters and scaling.
