Chapter 2
Developing the Site Plan
This chapter discusses site plan development for installing the 
Encompass
®
 4H Reader System.
Overview
Developing a site plan provides the foundation for the site’s system design and estab-
lishes the number and general location of primary components.
Also, consider the following factors when developing a site plan:
Type of tags used in the facility
Reader and tag alignment
Site layout and traffic flow
Encompass 4H Reader mounting requirements
Encompass 4H Reader electrical requirements
Encompass 4H Reader communications requirements
These factors provide relevant information regarding each site’s physical and electro-
magnetic environment and the conditions under which the system must perform.
Reading of Mixed Population Tags
The Encompass 4H Reader reads TransCore’s Super eGo
®
 (SeGo) protocol tags, the 
American Trucking Association (ATA) and International Organization for Standard-
ization (ISO) read-only tags, whether powered by battery or beam, application-spe-
cific integrated circuit (ASIC)-based tags with Intellitag technology, or Inter-Agency 
Group (IAG) tags. The reader can read the ATA or ISO read-only tags in the presence 
of Intellitag-based tags; however, attempting to read an Intellitag-based tag in the 
presence of an ATA or ISO read-only tag is not recommended.
Caution
Attempting to read an Intellitag-based tag in the presence of an ATA or ISO read-only 
tag may provide unreliable results.
The factors that influence the readability include, but are not limited to physical orien-
tation and configuration, type of read-only tag, ratio of backscatter cross-section of the 
tags, and whether the tag is battery- or beam-powered.
