For the SyncOut voltage to be
considered as high, it must
exceed 2.5 V. Similarly, it
must be 0.45V or lower to be
considered as low.

There is spike protection on both signal ports but there is no fi ltering on the input
port. It is important to consider noise issues (ground-loops, etc) as noise may
cause an unwanted start on sync trigger.
Example 1 Running three Vectrinos with synchronized sampling of
velocities in continuous mode.
Connect the SyncOut line from one Vectrino to the SyncIn line on the two
other Vectrinos. Connect the ground cables together. Choose Out put Sync for
Vectrino
for the fi rst Vectrino. This will be the master. In the setup for the two
other Vectrinos that will be slaves, check both boxes in the Input Sync (Start
on sync
and Sample on sync). With the rest of the setup identical for the three
instruments start the two Vectrino slaves fi rst. When the master Vectrino then
is started, it will trigger the start of the other two Vectrinos.
