Max 100ktl3-x lv

Hi there, how to connect 6 inverters in parallel.
The model is MAX 100KTL3-X LV
I have ShineMaster.
Logged in ShineMaster and in lan settings what is DNS?
Also from the logger is A1-B1
to the inverter in communication jack what numbers need to be to Master and then the others to Slave.
The numbers are from 1 to 16
I used 3-4 to 5-6 but the logger found only Master and not the others
