DRAFT TrimTrac 1.5 Technical Manual v0.3ab 24
Motion Sensor Override
This parameter is most useful during server application development and as an
override for units in the field that may have had a motion sensor failure. During
“normal” operation, however, the Motion Sensor Override should always be set to
default.
Setting the Motion Sensor Override to either “1=Motion Always” or “0=Motion
Never” causes the TrimTrac 1.5 operate as if it is in constant motion or at rest,
respectively. By forcing the device into either of these two modes, application
developers can see how the device is expected to operate in the field.
Should a motion sensor malfunction in the field, then this parameter can be used
to override its operation either on or off. For instance, if the motion sensor get
stuck and the device will not stop reporting after coming to rest, then this
command could be used to turn off the motion sensor altogether. Conversely, if
the motion detector stops sensing motion even while the device is known to be
moving, then the motion sensor could be over ridden into the “on” state.
Variable State Timeouts for High and Medium Priority Alerts
During normal conditions, the TrimTrac 1.5 operates in accordance with its
current parameter configurations; however, when a High or Medium Priority
Alert is activated, the frequency at which the TrimTrac 1.5 cycles through the
state machine can be varied. For instance, the TrimTrac 1.5 may be configured to
report once every 15 minutes, which may be adequate under “normal” conditions.
If, however, a High or Medium Priority Alert is activated, then more frequent
reporting is usually required. As such, the timeouts associated with the IDLE,
DELAY and TRANSMIT states can be individually selected based upon whether
a High and/or Medium Priority Alert has been activated. In the case of a High
Priority Alert, the QUERY state timeout can also be varied.
Additionally and as described elsewhere, the number of Transmit Attempts can be
set for High and Medium, as well as Low, Priority Alerts.
