Restoring Serial Port Settings

If you are not familiar with the configured settings of the

WMT700 wind sensor, or if the settings have been accidentally

changed, you may not get any response when you send the OPEN

command to WMT700. In that case, restore the serial port settings

to known values.

To restore the default serial port settings using Windows

HyperTerminal:

1. Connect a cable between your terminal computer, power

supply, and WMT700.

2. Open the Windows

HyperTerminal program.

3. Cancel the new connection.

4. On the File menu, click Properties.

5. Select the correct COM port and click Configure.

6. Regardless of the configured port settings of WMT700,

select the following communication settings:

- Bits per second: 19200

- Data bits: 8

- Parity: None

- Stop bits: 1

- Flow Control: None

7. Close the New Connection Properties window.

8. Connect to WMT700 using the RS-485 interface.

9. Switch the sensor power supply off and back on.
