Selecting data files I have the possibility to check GZIP, what is this for?

This compresses the data file and reduces the size by a factor of up to 10 which is beneficial for a shorter transmission and less power consumption. The data will need to be decompressed (unzipped) on the receiving server. OTT HydroMet Hydras 3 does this automatically.

I have Hydras 3 net but am not able to use the commands with the ecoLog 1000?

You need to have a Hydras 3 version 4.0 or higher to have ecoLog 1000 management network support.
