TRACKPOINT 3 OPERATION
3-21
Sequential Tracking/Priority Sequence: Select Normal to sequence through the enabled tar-
gets one after the other or select Priority to sequence back to this target on every other cycle.
NOTE: Only one target can be enabled as a Priority.
Depth Tab
The Depth Tab configures
the target depth function.
Select the Mode in which the
depth is input from; Teleme-
try, Analog, Serial Port (PC),
Manual. If the Beacon is a
(time-proportional) Depth
Telemetry version then se-
lect “Telemetry“ and then
under “Depth Mode Setup”
configure the Beacon’s Te-
lemetry parameters. If depth
is via an analog sensor, e.g.,
an ROV or SSS vehicle, then
select “Analog” and then un-
der “Depth Mode Setup” con-
figure the Beacon’s Analog
parameters. The analog port is available at the GYRO connector on the rear panel of the Unit. If the
target’s depth is available via a serial port, select “Serial Port” and then under “Depth Mode Setup”
configure the Beacon’s Comport parameters. Select the Depth Input sentence, DBS, DBT, PEIV1 or
DPT. (See formats below.) This Serial port is
available only at the PC’s serial input not the
Deck Units.
NOTE: If the entered depth is in-correct the cal-
culated horizontal range will also be incorrect.
In the TELEMETRY mode the depth is taken from
a depth telemetering transponder. The trans-
ponder sends two replies to the TrackPoint 3 per
interrogation. The first reply signal is used to
determine slant range and bearing, while the
second reply (whose delay from the first is proportional to depth) is used in the depth calculation.
Given these three parameters a three-dimensional position fix is calculated. The “Telemetry Depth
Setup” menu is used in conjunction with “Telemetry Mode”. It contains parameters to allow the op-
erator to change the telemetry reply frequency, and also to change the zero delay, full-scale delay
