GT Lite Operation and Maintenance Manual 

 

The inventory message consists of a standard logger message, followed by the type of 
inventory message (New or Change), tag datatype and tag data. 

The tag datatype indicates the type of tag data being transmitted.  Since each type of reader 
may contain data in addition to tag number, the tag datatype allows this data to be processed 

properly.  The list of current tag datatypes is below. 

Wavetrend RFID tags – Tag ID only 

Wavetrend RFID tags – All tag data 

Barcode tags 

EPC Gen2 – EPC only 

 

Software Upgrade Notification Message 

After a software upgrade for either low power controller or main processor, the device will 

return a message to confirm the upgrade is complete.  The message contains the processor 
upgraded whether the upgrade was successful or failed, and the current software version. 

Server to Device messages are sent from the server to the GT Lite.  During standard 

operation, the GT Lite will only look for an incoming message after a successful transmission.  
For example, the GT Lite will only look for an incoming GPRS message after successfully 
sending a GPRS message. 

While in “Always On” mode, the GSM receiver is left in an idle state.  While in this mode, the 
GT Lite will always be able to receive an incoming SMS
