Appendix C. Device Description Files

Applications that need to deal with device settings must reference a library of

device description XML files. These files are identified with a “.dd” extension

and are subject to change with new versions of the CR1000 type datalogger

operating systems. Each file includes the following information about a

device:

1. The device’s device type code

2. The common model number for that device

3. Information about the protocol used to configure the device

4. A setting catalog for each major version of the device. The setting catalog

will describe the details of all settings that are supported by the device.

Find the specific device setting ID in the Device Description File. That ID can

be used within an application to get or setting datalogger settings. Some of the

CR1000 type datalogger device setting IDs with their accompanying names

and descriptions can be found in the CR1000 partial Device Description File

below:
