DRAFT TrimTrac 1.5 Technical Manual v0.3ab 69
DELAY State
The DELAY State is where the TrimTrac 1.5 normally dwells after a state
machine cycle and ignores any detected motion. This effectively restricts the unit
to reporting no more often than the DELAY Timeout, T4; provided, however, all
Vehicle Adapter or Control Module alerts are in the “0=Normal” status condition
or have their modes set “1=Disabled” or “3=Monitor-only”.
1. Upon entering the DELAY State, the TrimTrac 1.5 starts DELAY
Timeout, T4. (LED Blink: OFF).
2. The unit will transition from DELAY state as follows:
a. To the IDLE state upon the earlier of:
i.
Expiration of DELAY Timeout, T4; or
ii.
Expiration of Scheduled Report Time, T18, if Scheduled
Reporting Mode is set “1=Enabled”.
b. To the QUERY state upon receipt of a data message if In-Motion
Polling is set “2=OnDemand while in Motion”.
3. To further conserve power during the DELAY state, the software filtering
of the motion sensor can be disabled by setting Reserved to “0=Disabled”.
While in this disabled condition, the Dynamic Filter Timeout, T21, and
Dynamic Motion Filter Counter, N4, parameters are ignored.
Alert Processing in DELAY State
Whenever one or more Vehicle Adapter or Control Module alerts are in some
condition other than “0=Normal”, and do not have their modes set “1=Disabled”
or “3=Monitor-only, alert processing during DELAY state shall be in the
following order:
5. If HPA Status is set:
a.
“1=Activated”, then go to immediately to the IDLE state;
b. “2=Sent”:
i.
If Position Age is set “1=Aged”, then go immediately to the
IDLE state; or
ii.
If Position Age is set “0=Current”, then go to the IDLE state
upon expiration of HPA Delay Timeout, T13.
6. If MPA Status is set:
a.
“1=Activated”, then go to immediately to the IDLE state;
b. “2=Sent”:
i. If Position Age is set “1=Aged”, then go immediately to the
IDLE state; or
