Sending a program to the data logger

TIP:

It is good practice to always retrieve data from the data logger before sending a program; otherwise, data may be lost. See Collecting data for detailed instruction.

Some methods of sending a program give the option to retain data when possible. Regardless of the program upload tool used, data will be erased when a new program is sent if any change occurs to one or more data table structures in the following list:

  • Data table name(s)
  • Data output interval or offset
  • Number of fields per record
  • Number of bytes per field
  • Field type, size, name, or position
  • Number of records in table

Use the following instructions or watch the Quickstart part 4 video .

After sending a program, it is a good idea to monitor the Public table to make sure sensors are taking good measurements. See Working with data for more information.
