3. To the QUERY state if the GSM protocol stack confirms that the attempt
to send queued TrimTrac 1.5 messages, other than a Motion Report,
succeeded.
4.
To the DELAY state if the TriggerType is set “1=Motion Detected” and:
a.
The TrimTrac 1.5 has already cycled through the FIX state due to
the Motion Report Flag being set “1=Report Motion in IDLE”; OR
b. The TRANSMIT Timeout, T3, expires or the TrimTrac 1.5 has
made Position Report Transmit Attempts, N1, or Status Message
Transmit Attempts, N2, whichever the case may be, before the
GSM protocol stack has confirmed successful transmission of
queued TrimTrac 1.5 messages.
Alert Processing in TRANSMIT State
Should HPA Status become set “1=Activated” during the current TRANSMIT
state, the TrimTrac 1.5 will terminate the current transmission attempt and go
immediately to the STATUS state.
Unless alert modes are set “1=Disabled” or “3=Monitor-only”, alert processing
during TRANSMIT state shall be per the flowchart shown in Figure 5 through
Figure 8.
