IMPORTANT:
It is
critical
that the built-in transmitter is
enabled
for all fine-scale positioning (VPS)
studies to allow for proper receiver time synchronization. For all other deployments, it is
recommended that the built-in transmitter be enabled to provide data that can be used for system
performance assessment post-deployment.
Figure 3-12: Enable Transmitter check box
Transmitter Profile options
Click the down arrow to display the options, and then select one for the receiver to use.
NOTE:
Sync Tag
is the default transmit profile and is recommended at all times
when not conducting range testing.
Sync Tag (HR 25-35s, PPM 270-330s)
This setting transmits with a
random
delay between 25 and 35 seconds for HR coding, and 270
and 330 seconds for PPM coding.
Use the
Sync Tag
setting if you are preparing your receivers for a longer-term deployment.
l
If you are conducting a positioning (VPS) study, Sync Tag detections will be used to
synchronize your receivers' clocks and facilitate accurate position calculation.
l
If you are
not
conducting a VPS study, use the Sync Tag setting to have your transmitter
act as a
control
or
sentinel
tag. In this case, you may use detections of the transmitter on
neighbouring receivers as a means of monitoring ongoing acoustic conditions.
