Page 17: Using The Configurator
User Guide Landmark Technic Signal Processor Using the Configurator When the processor is connected to a System 4 thermometer, the processor must be configured for use with that particular thermometer and have its operating parameters set. The temperature measurement system (i.e. processor and thermometer) is most easily configured using the LM Technic Configuration Software and a suitable PC. It is also possible to use a PC running standard terminal software and an RS232 port to perform the configuration, allowing the individual commands to be used. - Page 18 Landmark Technic User Guide Signal Processor Configuration parameters can be stored to the LM Technic and/or can be downloaded to a file on the PC for later use. It is possible to use the software without an LM Technic, however, only file menus will be available. 4.2.1 Setting a new configuration in a processor New. Use the ‘File’, ‘New’, menu to load default data into the configuration area. Thermometer. In the configuration area, select the thermometer type from the list box to match the thermometer actually connected to the LM Technic.

In the configuration area, adjust parameters as described in 4.2.1. Apply. When the required configuration parameters have been en- tered, press the ‘Apply’ button to send the configuration data to the LM Technic. A summary of the data sent will appear in the live data, confirming that the data has been received by the LM Technic. 4.2.3 Saving/Opening a configuration file Save.
