Verification

Before connecting PWD22/52 to a weather station or other host, a short
startup procedure is recommended.
1. Connect a terminal via RS-232 serial line to the sensor.
2. Set the terminal baud rate to 9600 bps and the data frame to contain
7 data bits, 1 stop bit, even parity.
3. Switch the power supply on.
4. After startup, the PWD22/52 output is the following:
VAISALA PWDxx V x.xx YYYY-MM-DD SN:XXXXXX
ID is also included, if configured. Example:
VAISALA PWDxx V x.xx YYYY-MM-DD SN:XXXXXX ID STRING: 1
If not, check the cabling and baud rate of the service terminal
(program). If wrong characters are shown, try other baud rates,
such as, 300, 1200, 2400, and 4800.
5. Wait for 20 seconds and enter into the command mode with the
OPEN command. Check with the STA command that no hardware
errors or warnings are detected.
6. Leave the command mode by typing CLOSE and check that the
automatic message appears in the display, if it was not disabled.
Other commands are described in Chapter 5, Operation, on page 47.
