Loading Settings from Configuration File
To facilitate the configuration of WMT700, all settings can be configured
at once using configuration files. You can send a text file containing the
configuration settings to the sensor with a terminal program, such as Tera
Term or Windows
®
HyperTerminal.
For a list of the parameters and their allowed and default values, see
Table 18 on page 82.
To change the parameters over the RS-485, RS-422, or RS-232 interface:
1. Use the G command to fetch the current WMT700 parameters.
2. Copy the values from the terminal program to a file. Remove the
parameters you do not want to change.
3. Disable error messages with the following command:
S messages,0
4. Clear the error counters with the following command:
CLEARERR
5. Send the file to WMT700 to change the settings.
6. To verify that the parameters have been set correctly (the values are
in the allowed range and all parameters were valid), read the error
counters with the following command:
ERRORS
If all values are valid, WMT700 sends the following response:
