Under the default configuration, Emergency Tracking can be triggered at any time by a quick press and
release of the Emergency button (momentary switch). Once enabled, holding the Emergency button longer
than three seconds takes the 9602-LP out of Emergency Tracking. When Emergency Tracking is active the
Emergency LED will illuminate. The Emergency trigger can further be customized using the AT command
^EST. This command specifies the type of emergency switch as either momentary (default) or latching
(similar to the toggle switch on the 9601-DGS-LP). The momentary switch type functions as described
above, but when set to latching, Emergency tracking is enabled only when the trigger is active. For example,
setting the emergency trigger to the falling edge and the switch type to latching will cause emergency
tracking to enable when the input level is pulled from high to low and then it will disable when the input
level returns to high.
The AT command ^PR controls input value reporting. When ^PR is enabled and a pin changes, an
unsolicited response, ^PV, will be sent on the serial port indicating the values of the input pins. Setting the
outputs is controlled by the AT command ^Pn. Outputs can also be set by remote update. For detailed
information regarding I/Os, users are referred to the manual “AT Commands for Model 9602-LP”.
5.0 CONFIGURATION SETTINGS
5.1 Modes of Operation
The 9602-LP can be in one of two operating modes at power up: (1) Command mode, or (2) Tracking
mode. When in Command mode, AT commands can be entered to configure the 9602-LP’s operating profiles
or the 9602-LP can be operated as a 9602-G (standard SBD-modem with GPS). As a reminder, developers
are encouraged to use SatTerm GUI software to set up the 9602-LP instead of using AT commands. When in
Tracking mode, the 9602-LP automatically transmits GPS reports defined by parameters in the active operating
profile (see description below). There are three different types of Tracking modes—Normal Tracking,
Emergency Tracking and Test Tracking. The 9602-LP is factory-set for AT^START0 to power up in Command
mode and can be reset to power up in Tracking mode by the AT^START1 command. After the 9602-LP is
powered up, the AT^TRK command can be used to switch from Command mode to Tracking mode and
switching from Tracking mode back to Command mode is done with the +++ escape sequence. The flow chart
in Figure 4 describes operating modes of the 9602-LP.
There are three types of operating profiles—active operating profile, factory-default operating profile and
user-defined operating profile. The active operating profile is the set of parameters currently in use by the
9602-LP. There are two user-defined operating profiles, profiles 0 and 1, available for the 9602-LP. Each user-
defined operating profile can be edited and saved at anytime through the AT command &Wn. The factory-
default operating profile is stored permanently on the 9602-LP’s memory and cannot be changed by the user.
Profiles 0 and 1 are initially set as the factory default profile.
At power up and as a default, the 9602-LP loads user-defined operating profile 0 into the active operating
profile. However, either one of the two user-defined operating profiles can be designated as the active
operating profile at power up through the use of the AT&Yn command. During power up, the factory-default
operating profile can be loaded (soft reset) into the active operating profile using the AT&Fn command. The
active operating profile will revert back to the user-defined operating profile designated under the AT&Yn
command at power reset. Similarly, the active operating profile can be soft reset with either one of the two
