DRAFT TrimTrac 1.5 Technical Manual v0.3ab 47
Continued Reporting After Coming to Rest
In the event a TrimTrac 1.5 continues to report after coming to rest, it may be
because the motion detector is overly sensitive for the given application
environment. Fine-tuning of the motion detector settings is achieved by changing
the motion timeout and second-count settings.
These configuration parameters include the Static Motion Filter Timeout, T7, and
associated Static Motion Filter Counter, N3, and the Dynamic Filter Timeout, T21
and its associated Dynamic Motion Filter Counter, N4, setting can be changed as
well.
In general, increasing a motion filter counter (Static Motion Filter Counter, N3 or
Dynamic Motion Filter Counter, N4) as a percentage of its associated motion
filter window (Static Motion Filter Timeout, T7, or Dynamic Filter Timeout, T21,
respectively) will decrease the motion sensor sensitivity.
Additionally, increasing the Motion Counter Threshold will decrease the relative
sensitivity of both motion detection filters.
TrimTrac Will Not Stop Reporting Every 2-3 Minutes
Chances are a Vehicle Adapter or Control Module was inserted into a TrimTrac
1.5 base when the MPA Mode was set “0=Automatic” and before the Vehicle
Adapter or Control Module was:
1. Connected to an external 9-32 VDC power supply; and/or
2. An end-of-line resistor was installed across the Yellow leads (See Figure
9, Vehicle Adapter Module Alert Wiring Diagram)
The TrimTrac Vehicle Adapter or Control Module has an internal rechargeable
standby battery that has a residual charge when shipped from the factory. This
residual charge is typically enough to support operation of the TrimTrac 1.5 when
the Vehicle Adapter or Control Module is first inserted into the TrimTrac 1.5.
Once the Medium Priority Alert is activated, the TrimTrac 1.5 will continuously
transmit nominally every 2-3 minutes until the Medium Priority alert status is
changed to “Acknowledged” from “Activated”. This can only happen once the
TrimTrac 1.5 has received the appropriately configured SET_ALERT message
from the server application.
WARNING:
Before inserting a Vehicle Adapter or Control Module into a TrimTrac base
unit:
A) Connect the red (+) and black (-) wires to a 9-32 VDC power source and
install a 100k Ohm resistor across the yellow wires; OR
B) Set the TrimTrac MPA Status to “1=Disabled”.
FAILURE TO DO EITHER OF THESE WILL CAUSE THE TRIMTRAC
1.5 TO IMMEDIATELY ACTIVATE A MEDIUM PRIORITY ALERT
