Transmitting D-PRS data

D Weather station transmission

When you transmit as a weather station, you should
set the weather station's settings, and input the
weather data to the [DATA] jack.
You can input the weather data from a third party's
weather device by converting it to the APRS weather
format in your PC or microcomputer.
After completing the weather station's settings, and
inputting the weather data, you can transmit as a
weather station.
NOTE: If the weather data is not input to the [DATA]
jack, you cannot transmit as a weather station.

"Weather." (p. 8-29)
2. On the standby screen, push
3. Touch "Weather Information."
• Displays the weather information screen as shown
below if the weather data is input to the [DATA] jack.
L When the weather information is displayed, you
can transmit as a weather station. If "-" is displayed
on the screen, the weather data does not input to
the [DATA] jack. In that case, check the input data
settings.

D Application setting

Configure the communication software as follows.
• Port: The COM port number that is used
by the IC-9700.*
• Baud rate: 4800/9600 bps*
• Data: 8 bit
• Parity: none
• Start: 1 bit
• Stop: 1 bit
• Flow control: none
* 1 Depending on the PC environment, the COM port
number used by the IC-9700 may be higher than
5. In that case, use an application that can set it to
higher than 5.
Set the baud rate in DV Data/GPS Out Baud Rate.
