Figure 4 

Also shown in Figure 4 is the GT Lite label.  It is shown in more detail in Figure 5 below.  It 
contains the device serial number in text as well as barcode forms, safety warning, and part 

number.   

GT asset monitoring unit serial numbers are 12 character numbers that begin with a letter to 

signify the device type.  All GT Lite serial numbers begin with the letter ‘L’.   

The GT Lite part number is 202964 as shown below.  Different dash (such as -01 shown 
below) numbers signify different configurations of the product.  The base configuration is -01.  

Other configurations are described in Section 2.

To conserve battery life, the GT Lite stays asleep as much as possible.  The device wakes to 
send messages due to timed reporting or alert reporting. 

Timed reports are based on a configurable reporting interval.  When the interval is up, the 

device wakes, creates a report and if a network is available sends the report.  If no network is 
available, the report is stored until it can be sent.  The reporting interval can automatically 

change based on the availability of external power and whether or not the device is in motion.  
These intervals can all be changed remotely. 

Alert reports occur when a sensor is read in an alert condition.  If this happens, the device 
immediately sends creates and sends the report if a network is available.    If  no  network  is 

available, the report is stored until it can be sent. 

Between reports, the device is in deep sleep over 95% of the time, waking slightly to take 
sensor readings.
