System Guide Organization
TransCore oers the Encompass 4 Reader in two models: one with an integrated antenna and one that
requires connection to an external antenna. In this system guide, information and instructions for both
Encompass 4 Reader models are presented. Where separate instructions dictate, a section detailing one
Encompass 4 Reader model is followed immediately with a section detailing the other reader model. In this
system guide, the reader with an integrated antenna is listed first. In cases where the information does not
warrant a separate section, the addition of “...or antenna” distinguishes between the Encompass 4 Reader
models.
System Description
The Encompass 4 Reader System is a dual-protocol reader supporting the low-cost, high-performance
SeGo radio frequency identification (RFID) technology. SeGo technology provides the capability to read
miniature RFID tags in a myriad of options including rugged, durable, or thin flexible forms such as the
eGo Plus Micro Mini Sticker Tag. The Encompass 4 Reader System also supports legacy transportation
applications such as gated toll, parking, or security gate access and is designed to be compatible
with existing TransCore SmartPass® parking access control applications certified for licensed use. The
Encompass 4 Reader System also supports TransCore ATA/ISO tag types, as well as the IAG tag protocol.
The Encompass 4 Reader System is a high-power unit that can read both half-frame and full-frame tags.
The reader output power can be adjusted using reader commands.
Reader
The Encompass 4 Reader System consists of an input/output (I/O) module, a reader logic board (also
called a tag decoder), a radio frequency (RF) transmitter/receiver (called the RF module), and a patch
antenna.
Note: A dedicated electrical power supply must be present at the site and available to the
Encompass 4 Reader at all times. Refer to “Electrical Power” on page 2–16.
A second version of the Encompass 4 Reader is designed to be used with a high-performance external
antenna. These Encompass 4 Reader System components are contained in a highly reliable, compact, and
easy-to-install environmentally-sealed package. Figure 1 shows the front and side views of an Encompass
4 Reader System.
