TrimTrac ProE Locator Technical Manual v2.0e

High-Performance Tracking and Reporting
If power consumption and communication costs are of no object and the
application requires maximum fix density and constant communication, then the
device can be configured to report as frequently as once every 30 seconds and
could be polled at any time. The communication cost would increase
substantially if the device were transmitting position fixes at the rate of one every
30 seconds. In this configuration, it is not practical to operate on four AA
alkaline batteries except for very short periods measured in hours (not days). But
if you and or your customer are willing to take these hits, then the TrimTrac ProE
can be an extremely cost-effective way to monitor dynamic assets.
If GPS Fix Rate is set to “1=1Hz GPS”, Anytime Polling is set “2=Anytime
OnDemand”, QUERY Timeout, T5 and DELAY Timeout, T4 are both set to 10
Seconds; all other parameters at default, and the unit has good GPS and GSM
coverage, then the maximum reporting frequency one can expect from a TrimTrac
ProE is one transmission every 30 seconds. This reporting rate will, however,
significantly impact power consumption and communication cost, especially if
SMS messaging is used.

Allows near constant
communication with the
TrimTrac ProE even while
actively computing a new
position fix or transmitting
a message.
Drastically reduces battery
life to as little as 4 days
even if there is no new
position fixes are being
computed and transmitted.
Actual battery life
dependent upon, amongst
other things, how frequently
the GSM network forces the
device to re-register on the
network. If longer response
times are acceptable, then
consider setting Anytime
Polling to “1=Duty-Cycled”
DELAY Timeout, T4, set to
minimum 10 seconds
Minimizes the time between
message transmissions

.
QUERY Timeout, T5, set to
minimum 10 seconds
Minimizes the time between
message transmissions
Should be set no lower than
60 seconds if either In-
