To start the recording at the same time (“synchronous acquisition start” mode, each unit would still
use its own clock for sampling) this feature, the user must connect the units using the
synchronization cable, power them up (make sure the recording mode is free run on all the units),
and press “Record” button on one of the units connected. The config files on both units must be:
This technique will assure the recording start at the same time, but due to the slight difference in
internal oscillator characteristics, the number of samples will drift apart with time. To assure the
simultaneous sampling, the synchronization technique must be used. To do that, one of the units
must be designated as master and its configuration file shall be as following:
The rest of the units must be designated as slaves and their config files shall be set as following:
An important thing to remember is that this only works in “Free run” mode. If everything is
configured as explained above, after the units are turned on, the master will show a green light once
it’s ready to record while the slave unit(s) will show orange on the right with blue on the left to
designate its slave configuration:
