TAIP commands
message type allows you to issue TAIP
commands to the GPS module (if the module is configured for
TAIP rather than NMEA). You can send any TAIP command at
any time using the
MT_CREQ_GPS_CONF
field, however if you
use this to configure the GPS module, the configuration does
not persist across power cycles. If you want to configure the
TAIP reports such that the configuration persists across power
cycles, it is best to include the TAIP commands in the initial
ization strings for the modem, since commands in the initial
ization strings are executed each time the modem is powered.

When the MP 555 GPS has a CDMA connection to the
network, it sends the summary/registration message
(
MT_SUM_REG_IND
) to the host application at regular
intervals, as well as on the occurrence of specific events. This
message contains an engine ID, the device name, GPS data in
the form of either a TAIP or NMEA message, the RSSI value,
and the status of the digital input ports.
The interval at which the
MT_SUM_REG_IND
message is
regularly sent is governed by three timers: the low rate timer,
the fast rate timer, and the GPS timer. These are discussed in
the section “Report frequency timers” on page 39.
As well as occurring at intervals based on the timer settings,
the
MT_SUM_REG_IND
message is triggered by the events
listed in the following table:

Event
Description
Change in IP
address
Anytime the MP 555 GPS changes IP
addresses,
MT_SUM_REG_IND
is sent
for registration.
Digital input alarm
When an alarm is triggered by a drop or
rise in the level of a digital input port,
MT_SUM_REG_IND
is sent at a faster
rate (as determined by the fast rate timer
described above). The message is sent
at the faster rate until it is acknowledged.
See “Alarm acknowledgement” below.
Change in battery
status
MT_SUM_REG_IND
is sent whenever
the battery voltage rises or drops to pre
determined levels.
Change in ignition
sense
MT_SUM_REG_IND
is sent when at any
change in ignition status occurs.
