REMOTE COMMUNICATIONS

:MEMOry:RECA:DATA:YYYYMMDD?

Queries for data previously stored in the internal memory of the FS22 on the specified
directory. Directories name have the following format «YYYYMMDD». Returns the data
containing the timestamp and the absolute wavelength values of the fiber Bragg grat­
ing sensors in each channel. Timestamp is calculated using the number of seconds
elapsed since 12:00 A.M. Friday, January 1st, 1904. The interrogator will not be
responsive to other commands, while data file is being transferred. The command
does not delete downloaded data. This command is sent via port 3500 and corre­
sponding data is received through port 3365.
Files larger than 100 MB must be downloaded using BraggMONITOR.

Example:
