Hover Timer: The time, in minutes, between sending automated position reports while
hovering. Hover events will replace the periodic events when they are due to be sent.
Hovering can only be reported for a helicopter which has a collective or weight on wheels
switch to detect take-off and landing. The hover timer cannot be enabled if using speed
only.
»
Heading Timer: The minimum time, in minutes, between position reports when the aircraft
is changing heading.
To Change the Interval for the Selected Timer:
»
Using DZMx Connect. Go to
Settings > Tracking > Periodic
. Select the required periodic
timer settings.
»
Using the DZMx keypad. Go to
MENU > Tracking > Periodic Events
. Use the LEFT

to reduce the interval and the RIGHT
key to increase the interval. The intervals are
displayed in minutes. Press the ENTER key to save the setting. Press END return to the

Enabling HD Tracking
While tracking interval over Iridium is set in minutes, with tracking over cellular IP, the interval can
be reduced to 15 seconds (High Definition Tracking).
To enable or disable HD Tracking using DZMx Connect. Go to
Settings > Tracking > General >
HD Tracking Mode
and select one of the following options:
»
On: Enables HD tracking, thus allowing up to 1 tracking message to be sent every 15
seconds by the DZMx while a data connection is available.
»
Off: Turns HD tracking off, reverts to the periodic tracking interval as set-up in "
»
Cell HD: Turns HD tracking on for cell, sending position reports every 15 seconds. If
messages start to queue, due to being in a poor signal area, then the frequency of the
tracking messages will drop back to standard periodic intervals. The rate will switch back
to using the HD interval setting as soon as the cell modem gets a good signal and cell
data becomes available again.
»
Full HD: Turns HD tracking on for cell, sending position reports every 15 seconds, and
stores positions every 15 seconds on sat, sending them as a group every minute. The
DZMx will send messages out via an SBD message at 1-minute intervals to maintain an
HD interval track log when cell data is not available. If cell data is disabled, or no cell
modem is fitted it is possible to track in Full HD mode continuously using SBD exclusively.
Each SBD message will contain up to 3 crumbs as historical reports, as well as the current
position. If the HD interval is set to longer than 15 seconds, then the SBD message
interval will also change in Full HD mode e.g. to every 2 minutes when the HD interval is
set to 30 seconds.
Note:
Any timer can be disabled by setting its interval to zero.
Note:
The DZMx will not track at the HD rate when on the ground. The DZMx will use the On
Ground periodic timer setting (which may be disabled by setting to 0).
