To calculate the UTM zone start the Survey Calculator. Enter the degrees and decimal degrees of
your local latitude and longitude. If GPS is available the position is automatically set to the current
GPS position. Click OK to apply and exit. The calculator, upon exit, sets the parameters in the
UTM Grid Setup.
Cycle Control
The Cycle Control tab allows the operator to set the system cycle time between beacon
interrogations or select an external trigger source.
Triggering Mode
•
Internal
The cycle time is controlled internally and is set by the operator. Internal triggering modes
are described below
•
External
System is triggered via the NAV IN connection on the rear panel.
TTL type 5 volt pulse triggers on rising edge
.
Before the triggering modes are described it is important to understand the factors within the
system that can effect the system cycle times possible.
The expected maximum range of each enabled beacon has the largest effect, as the maximum
range parameter of a beacon increases, then the fastest possible cycle time of the system will
increase. Also the beacon channel and type will effect the cycle time, different beacons have
different internal turnaround times (the time taken from the beacon receiving an acoustic
interrogation to sending an acoustic response) and therefore effect the total time taken to receive a
response from a beacon at range.
