TrimTrac ProE Locator Technical Manual v2.0e 8
Cost-effective, Universally Available Communications
The TrimTrac ProE takes advantage of the near universal availability of GSM
SMS text messaging while also leveraging cost-effective GPRS data rate plans.
Typical SMS plans offer very extensive inter-network roaming capabilities, both
within a host country and internationally. SMS plans also tend to be too pricey
for applications requiring more than a few reports per day.
GPRS data plans, on the other hand, typically allow for lower recurring
communication costs although GPRS coverage and roaming can be restricted in
some areas. The TrimTrac ProE takes advantage of both technologies by
automatically selecting GPRS wherever such service is available, while relying
upon SMS text messages as backup when outside GPRS coverage. This helps
minimize recurring communication costs while allowing the greatest coverage
possible.
Hardware Options
A number of different hardware options are available to enhance the suitability of
the TrimTrac ProE to particular application requirements. These options include
a miniature external GPS antenna that allows for more discrete, protected
installation of the TrimTrac ProE.
In addition, two plug-in modules are offered; both provide connection to external
9-32 VDC power to eliminate the need to change batteries and can monitor inputs
of three different priority levels. The control module also provides two outputs
that can be used to control other on-board devices or systems, such as door locks,
immobilizers and remote start systems.
To address different mounting requirements, two mounting brackets are offered.
A metal bracket is available for more permanent installations while a “quick-
release” style plastic bracket is used when rapid insertion and removal of the
TrimTrac ProE is desired. This is particularly useful when a battery- powered
TrimTrac ProE is routinely moved from one asset to another.
