ThermoWorks RTR-500GSM WIRELESS LAN OR GSM (CELLULAR) LOGGERS - Manual (Page 11)

10 Send Recorded Data Settings
This is the screen where downloads of the data recorded by the loggers are
enabled, the frequency of downloads is specified and the transmission
method is set. Recorded Data is delivered as a .trz file, which is viewable
using TandD’s Graph software, and can be sent as frequently as eight
times per day. Note that the selected transmission method applies to all
times specified. Again, if transmission via FTP is selected and is
not included in the File Name, each transmission will overwrite the
previous one, resulting in a single data file residing on the server no
matter how many uploads are made. Also, as with sending Current
Readings, it is important to note that if Recorded Data is being sent to a
WebStorage Service account the Recipient Folder entry must be left blank.
11 Transmission Tests
The Transmission Test window is a useful tool for checking the settings
you have made. The Transmission Tests determine if communication can
be established via the specified method without errors being returned (no
actual data is sent). It is highly recommended that you use these tests to
confirm the server and logon information that you have entered before
putting the RTR-500GSM into service. You will want to correct any
entry errors before you deploy the unit to a remote or mobile location.
If you receive an error message for any of the tests, try it a few times.
Sometimes the connection through the cell network takes a bit to establish.
If the error message persists refer to the Error Code List in the Operation
Guide.
