TransCore 0596465PT15 Manuel D’Utilisation

4H Reader System also supports the TransCore eGo and TransCore full frame and half 
frame ATA/ISO tag types, as well as the IAG tag protocol.

The Encompass 4H Reader System consists of an input/output (I/O) module, a power 
supply, a reader logic board (also called a tag decoder), a radio frequency (RF) trans-
mitter/receiver (called the RF module), and a patch antenna. 

These Encompass 4H Reader System components are contained in a highly reliable, 
compact, and easy-to-install environmentally-sealed package.

The Encompass 4H Reader System has the capability to read TransCore SeGo proto-
col tags, the Intellitag-based eGo protocol tags, TransCore ATA protocol, and 
TransCore ISO-compliant read-only full- and half-frame tags, as well as IAG protocol 
tags.

The Encompass 4H Reader System directs the RF module to generate an RF signal, 
which is broadcast through the integrated antenna. Entering the Encompass 4H Reader 
System’s reading range, a TransCore RFID tag installed on a vehicle or other object to 
be tracked adds its programmed identification information to the signal and reflects 
the signal back to the Encompass 4H Reader System. The Encompass 4H Reader Sys-
tem receives this modified, or modulated signal, and decodes the tag data carried by 
the reflected signal and transmits this data to a local host computer for processing.
