Enhanced Functional Capabilities
Position reporting triggered by motion continues to be an important attribute of
the TrimTrac ProE; however, a range of powerful new functional enhancements
now augments this basic capability. The TrimTrac ProE is backwards compatible
with applications developed for the first generation TrimTrac.
On-board Geofencing
The TrimTrac ProE can self-monitor up to two geofences. These geofences can
be either rectangular or circular with reporting based upon whether the device is
inside or outside the geofence area or when it has simply crossed the geofence
boundary. Geofences can be established either during initial activation of the
device, established on-the-fly via over-the-air commands or upon operation of a
local switch connected to the TrimTrac ProE input module. These capabilities
allow the device to be “locked down” where needed without creating nuisance
reports during normal operation. (See AT+CTKK on page 123)
Scheduled Hours Mode
The feature is particularly useful when monitoring commercial assets that are
used during certain hours of the day, but then are supposed to remain at rest or
within a relatively constrained area during after hours.
The Scheduled Hours Mode feature is used to establish how the device reports
motion or during what time periods a geofence is enforced. During normal hours
of operation, position reports may not be needed unless, for instance, a geofence
has been violated. Outside normal hours of operation, however, any motion of an
asset may be considered “unauthorized” and it would be desirable for the
TrimTrac ProE to report this motion and its current position. Monitoring of
equipment at a construction site is an application example that would use this
Scheduled Hours feature, possibly in conjunction with a geofence. (See
AT+CTKZ on page 134; SET_EXT2_APP_CONFIG on page 152)
Runtime Meters (2)
Equipment maintenance schedules are often managed based upon accumulated
run-time hours. The TrimTrac ProE offers two resetable runtime meters: one is
triggered by motion and, if a plug-in module is used, the other can be hardwired
to contacts on a sensor, such as an oil pressure switch. (See AT+CTKZ on page
134; SET_EXT2_APP_CONFIG on page 152)
Start/Stop Reporting Mode
There are two Start/Stop Reporting modes available under the Report Delay Flag
settings. Alternately, the Motion Report Flag can be used in combination with the
