FAQ. What does the message 'data buffer full, losing data' mean?

It means the PC being used is not able to handle the data at the selected speed - there are a few things that can be done to improve the data capturing:

1) In the Instrument Set Up panel > Acquisition Rate tab, configure the number of Channels and FBGs/Channel that are actually connected. If you leave it as the defaults (4 Channels and 16 FBGs) then the interrogator will pad the data messages with zeroes.

2) If just wavelengths are being logging then Basic Acquisition could be used. SmartSoft will perform less processing than in Enhanced Acquisition because it doesn't need to check the coefficients set up in the Sensors table.

3) Use a PC with higher processing power. It can be tricky to assess but generally the faster the processor and the newer the processor technology the better.
