8.2.2.5. Software synchronisation 
When the data that we get from asynchronous devices includes also a time-stamp, DEWESoft® can do                
a so called software synchronisation. In this case, the channels will still be asynchronous and will have a                  
time delay relative to other synchronous channels, but at least the time-drift will stay almost constant.                
The DS-NET plug-in will always use soft sync for asynchronous channels. Image below “ Soft sync ” shows                
3 channels of 3 different DS-NET systems. DSNET1 and DSNET2 are connected via hardware sync cables                
(DSNET3 is not). We do not use any analog device. You can see that the channels of the synchronised                   
systems DSNET1_Voltage, DSNET2_Voltage are perfectly aligned to each other and the the            
asynchronous channel DSNET3_Voltage of the 3rd (not hardware-synchronised) system is delayed by            
some milliseconds (which is often acceptable when you are measuring slow signals). Even if you leave                
that measurement running for days and weeks, the time drift will stay almost constant. 
