5.3. Synchronisation
If running a dual head system it is important to set the synchronisation of the
Profilers correctly. The synchronisation is set using the
Setup
dialog which
is accessed by right-clicking on the main window and selecting
Setup
and
then
Sync Mode
.
Scan Sync
If running a dual head system, this mode is the minimum that should be
selected. The
Scan Sync
control will ensure that both master and slave
Profilers start their sweep at the same time. This is important to ensure they
are always scanning at the same point along the trench.
This synchronisation mode will ensure accurate mean altitude readings being
derived from the averaging of both Profiler scans.
Ping Sync
This is a 2nd level of synchronisation that, in addition to
Scan Sync
, will
force both Profilers to ping at interleaved intervals. This control is normally
enabled in cross-profiling applications, i.e., where the scans overlap in the
middle, where there may be cross acoustic interference between the pings of
both Profilers. When
Ping Sync
is enabled the master will ping first followed
by the slave followed by the master and so on until the scan/sweep of each
head is completed.
Note
In applications where there is enough separation/distance between
the mounting positions of master and slave heads and where the
