Health Limits for Encompass 4H Reader Using Integrated Antenna (902 to 928 MHz)
Within the United States, environmental guidelines regulating safe exposure levels are issued by the Occupational Safety and Health Administration (OSHA).
Section 1910.97 of OSHA Safety and Health Standards 2206 legislates a maximum safe exposure limit of 10 milliwatts per square centimeter (mW/cm
aged over 6 minutes at 915 MHz.
Although not binding, other organizations such as the American National Standards Institute (ANSI) and Health Canada Safety Code 6 (2009) have issued similar guidelines that are more restrictive than the OSHA limits (ANSI C95.1).
Health Canada Safety Code 6 guidelines recommend a maximum safe power den-
sity in W/m
2
, 0.02619ƒ
Thus, the maximum permissible exposure for general population/ uncontrolled
exposure at 915 MHz is 2.77 W/m
The RF power density generated by the Encompass 4H Reader was calculated
using a maximum antenna gain of 11 dBi, equivalent to the antenna gain of the
integrated antenna.
Warning
At 0.291 W transmitted power and a distance of 13 inches (33 cm) from the
reader, the maximum power density calculated was less than 2.77 W/m
the reader at least 13 inches (33 cm) from the general public. Maintenance personnel must remain at least 4.8 inches (12.3 cm) from reader when system is
operating.

The data confirms that the TransCore Encompass 4H Reader effectively meets
OSHA requirements and thus does not represent an operating hazard to either the
general public or maintenance personnel.

Limites d’innocuité du lecteur Encompass 4H utilisé avec une antenne interne (902 à 928 MHz)
Aux États-Unis, les directives environnementales concernant les niveaux d’exposition
acceptables sont émises par l’OSHA (Occupational Safety and Health Administration).
L’article 1910.97 de la norme de santé et de sécurité 2206 de l’OSHA

D’autres organismes de normalisation tels
Institute) et le Code de sécurité 6 de Santé Canada ont émis des directives similaires,
mais non obligatoires, qui fixent des limites plus restrictives que celles de l’OSHA
(notamment la norme ANSI C95.1). Les normes de Santé Canada Code de sécurité 6
recommandent de ne pas dépasser la densité de puissance suivante, exprimée en

0,02619ƒ
W/m
Ainsi, le niveau maximal d’exposition permis pour la population générale et les situations d’exposition non contrôlée à 915 MHz est de 2,77 W/m
période de 6 minutes.
La densité de puissance des RF générées par le lecteur Encompass
culée pour un gain d’antenne maximal de 11,0 dBi, soit l’équivalent du gain de
antenne interne.
Mise en garde
Avec une puissance transmise de 0,291 W, la densité de puissance maximale calculée à 13 pouces (33 cm) de l’antenne était inférieure à 2,77 W/m
précaution, installer l’antenne à au moins 13 pouces (33 cm) de la population générale. Le personnel d’entretien doit se tenir à au moins 4.8 pouces (12,3 cm) de
l’antenne lorsque

How It Works
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 T ransCore 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 System receives this modified, or modulated signal, and decodes the tag data carried by
reflected signal and transmits this data to a local host computer for processing.

Unobstructed Line of Sight
For optimum readability, install the Encompass 4H Reader and the vehicle’s tag so
that when the vehicle approaches the Encompass 4H Reader, the tag is directly facing
the reader and the line of sight is clear between the Encompass 4H Reader and the tag.
If a fence or barrier is between the tag and the reader, the Encompass 4H Reader cannot reliably read the tags. Figure 2-2 illustrates possible installation locations of an

Note: Metallized coatings on some vehicle windshields and windows shield the RF
energy emitted by the Encompass 4H Reader and may cause tags to be misr ead. Many
metallized windshields have areas that are not metallized in which the tag can be
placed and reasonable results achieved. If there are no openings in the metallized
coating in which to install an interior tag, install exterior-type tags on the exterior of

Site Layout and Traffic Flow
The following site layout and traffic flow considerations are critical when determining
Encompass 4H Reader installation locations:

• Other Encompass 4H Reader units in the area
• Lane configurations
• Reflection, refraction, and diffraction of RF signals
• Existing signal interference at the site

Developing the Site Plan
The Encompass 4H Reader Read Zone
The Encompass 4H Reader must be able to read the tag data properly within a specified area, called the read zone, without reading other nearby tags or interfering with
other Encompass 4H Readers at the site. The following are some of the factors that
affect the size and shape of the read zone:
• Mounting method used (pole or wall mount)
• Mounting location (overhead or side mount)
• Height from the ground and mounting angle
• Indoor or outdoor location
• RF output attenuation
• Range discrimination setting
• Other sources of interference and reflection
The Encompass 4H Reader must be positioned to allow the RF signal to travel to and
return from the tags within the designated range and be placed in an area where it is
not likely to be bumped out of alignment. If the reader becomes misaligned or some
nearby structure is added or removed, system operation can be seriously affected.
For instructions on setting the read zone, see “Fine-Tuning and Verifying the Read
Zone” on page 8-19.
Other Encompass 4 Readers in the Area
Encompass 4 Readers may not operate accurately if they directly face each other or
are positioned back-to-back.
Lane Configurations
TransCore recommends that traffic be guided through a controlled lane to consistently
obtain accurate tag readings and to prevent physical damage to the Encompass 4H
Reader. The following subsections describe some common lane configurations and
offer suggestions for positioning the Encompass 4H Reader within the controlled traf
fic flow.
Note: Regulatory requirements restrict the amount of RF power to 4 Watts EIRP that
can be transmitted from the Encompass 4H reader. In a side fire mounted application,
this reduction in RF power has been shown to impact the available read zone size and
speed at which the tagged vehicles can pass by the reader an d b e reliably read for all
tags except ATA battery tags. If any other tag type is being used, the end user needs
to be aware of the reduction in performance and should perform testing in their antic
ipated application to confirm it will meet their system requirements.

Gate with Center Island Configuration
Figure 2-6 illustrates a typical gate application with the Encompass 4H Reader units
positioned on a center island to read tags mounted on
driver’s side (United States). The readers are placed to allow time for the gate to open
so the vehicle can roll through without stopping while not allowing room for an
untagged vehicle to be between the vehicle being read and the gate.

Lane Configurations for Encompass 4H Readers
TransCore recommends that traffic be guided through a controlled lane to consistently
obtain accurate tag readings and to prevent physical damage to the Encompass 4H
Reader.
Reflection, Refraction, and Diffraction of RF Signals
RF signals can be reflected, refracted, or diffracted by metal objects, walls, and even
wet pavement or ice. Any of these factors can alter or degrade system performance.
When designing your site plan, you must consider permanent structures and transient
factors in the vicinity that may affect RF signals being generated by the Encompass
4H Reader. Permanent structures include buildings, chain link fences, guard shacks,
and gates. Transient factors include passing traffic and local weather conditions, such
as rain or snow. Symptoms of reflection, refraction, and diffraction include reading
tags that are out of the desired read zone or tags being read from another lane.
The most common RF reflectors are
tially reflected by nonconducting materials suc
crete. When nonconducting materials in the system
increase reflection of RF signals.
The Encompass 4H Reader mounting location, aiming, and range
and use of presence detectors can reduce interference from RF reflections. When these
actions cannot adequately control reflections, other techniques such as shielding,
absorbing, range sensitivity adjustment, or barriers can also be used. See Chapter 9,
”Troubleshooting and Maintenance” for more information.

2-12
Developing the Site Plan
Existing Interference
Interference from RF and electrical sources can degrade system performance and must
also be considered in the site design. Fluorescent lights, neon signs, nearby radio sta
tions, or power lines can interfere with the optimal operation of the system. The mag netic impulse noise from relays that control gate opening and closing can also disrupt
the RF signal.
Interference may degrade both reader and tag performance. Existing interference at
the site may be shielded, removed, or positioned further from the Encompass 4H
Reader.

Strong RF sources of any frequency , in proximity to the tag, can preclude the tag
Chapter 9, ”Troubleshooting and Maintenance” ).
Electrical and Communications Requirements
All construction work at the site must be completed before installing the Encompass
4H Reader. Electrical and communications cables should be installed according to all
applicable local and federal building code requirements. Specific instructions for posi
tioning and installing the Encompass 4H Reader are discussed in Chapter 4, ”Install-
ing the Encom pass 4H Reader”.

Junction Box
Use a watertight junction box that meets applicable local and national building codes
for connecting power and communications wiring. The junction box houses the termi
nal strip for power and communications connections. TransCore recommends a
NEMA Type-4 junction box with a back mounting panel.
Power and Communications Cables
Cable length for power and communications depends on the physical characteristics
of the Encompass 4H Reader installation site.

Host Communications
Your site design must include communications between the Encompass 4H Reader
and a host computer. The Encompass 4H Reader communicates with the host computer through an asynchronous serial line or th
line can be an RS
–232 interface or an RS–422 interface. The host computer must be
able to accept one of the interfaces shown in Table 2-4.

RS–232 Interface
Use an RS–232 interface if one or more of the following conditions apply to your site:
• The host computer system is 50 ft (15.2 m) or less from the Encompass 4H
Reader.
• The host computer system is more than 50 ft (15.2 m) from the Encompass 4H
Reader and a pair of RF modems or limited distance modem/l ine drivers over
copper wire are used for communications between the Encompass 4H Reader and
the host. The distance from the RF modem to the Encompass 4H Reader should
not exceed 50 ft (15.2 m).
• Other common communications devices that can extend the RS–232 distance,
such as fiber optic modems, have been selected.
The standard RS–232 connection maximum distance depends on the baud rate, cab le
type, and the RS
Note: When extending the RS-232 interface, use a three-pair cable such as Belden
2919. Use a twisted pair for the black (RxD) with ground (black of the black/yellow
pair), and a twisted pair for red (TxD) with ground (black of the black/yellow pair).
The third pair of the three-pair cable can be used for a spare in the event either of the
other two pair are damaged or fail. The cable shield should be tied to a single-point
earth ground on the controller end of the cable.

RS–422 Interface
Use an RS–422 interface if one or more of the following conditions apply to your site:
• The host computer is more than 50 ft (15.2 m) from the Encompass 4H Reader.
• The host computer has an external limited-distance modem.

Choosing, Installing, and Removing Tags
Installing eGo Plus License Plate Tags
Metallized coatings on some vehicle windshields and windows absorb the RF energy
emitted by the Encompass 4H Reader, thus causing tags to be misread. You must use
exterior LPT s on vehicles with metallized coatings on their windshields and windows.
Use license plate installation techniques to install tags on the exterior of vehicles that
have this type of window coating.
Note: The read zone of an overhead Encompass 4H Reader should be adjusted
accordingly when an exterior tag is installed on a license plate, or the read zone will
be reduced.
Required Materials
• Screwdriver (flat-blade or Phillips depending on the vehicle’s license plate
mounting screws)
• Optional TransCore Exterior T ag Accessory Kit (19077-01). This kit contains
tamper-resistant mounting screws and wrench.
• eGo Plus LPT
Positioning eGo Plus License Plate Tags
The eGo Plus LPT is installed over the license plate at the upper part of the vehicle’s
front license plate area.
Note: If your state does not require a front license plate, install the LPT in the area
where the license plate would normally be mounted. If your vehicle does not have a
front license plate area, contact your tag agency for other tag options.
The orientation of the tag is important. The tag must be mounted so that the holes on
the tag base plate are on the top edge.
eGo Plus LPT Installation Procedures
To mount the eGo Plus LPT
1. Remove the screws from the license plate area of your front bumper (Figure 3-
13). If your vehicle does not have mounting screws you will need two self-
tapping threaded screws. You can also contact the tag agency to inquire about the
optional TransCore Exterior Tag Accessory Kit.
Note: You may need to use longer screws to fasten the LPT over the top area of your
license plate.

Note: The read zone of an overhead Encompass 4H Reader should be adjusted
accordingly when an exterior tag is installed on a license plate, or the read zone will
be reduced.
Exterior tags may be installed on metal or plastic bumpers using the existing license
plate bracket and hardware.
The tag can be mounted on the front bumper where the license plate is normally
located or mounted directly to the front license plate or license plate bracket. Once
installed, the face of the tag should be pointing directly forward or slightly upward. If
the bumper, license plate, or license plate bracket has any material that overhangs the
tag, the tag will not function properly.
Required Materials
You need the following supplies to install license-plate mounted tags:
• Exterior LPT
• Two 0.25-inch (.63 cm) bolts and nuts (user-supplied). Length of the bolts can
vary depending on vehicle model.
• Screwdriver and wrench (user-supplied)
• 0.25-inch (.63 cm) spacers or washers (if needed). Thickness of spacers can vary
depending on vehicle model.

Encompass 4H Reader System Guide
Positioning ATA License Plate Tags
The orientation of the tag is important. The tag must be mounted so that the holes on
the tag base plate are on the bottom edge. See Figure 3-22.
Figure 3-22 Proper Tag Orientation
When positioning the tag, observe the following guidelines:
• The tag should be horizontal and parallel to the ground.
• The tag face should be perpendicular or tilted slightly upward.
• The tag may lean to the rear a maximum of 30 degrees.
• The tag may lean to the front a maximum of 10 degrees.
ATA License Plate Tag Installation Procedures
To mount the LPT
1. Position the tag so that the holes in

2. Line up the holes in the tag as follows:
• If mounting the tag to a license plate or lice
nse plate bracket, line up the
holes in the tag to the upper holes of the license plate or license plate
bracket.
Note: Do not mount t
he tag to the bottom holes of the license plate or license
plate bracket. The reflective material on the license plate may interfere with the
proper functioning of the tag.
• If mounting the tag to the bumper, line up the
holes in the tag with the holes
in the front bumper where the license plate would normally be located.
See Figure 3-23.
3. Insert bolts through the tag base plate holes
and the holes in the bumper or the
holes in the upper portion of the license plate area. See Figure 3-24.

6. Tighten the bolts and nuts with a screwdriver and wrench to secure the tag to the
vehicle.
Types of Bumpers
When mounting tags directly to a bumper, consider the following factors:
• Tags can be mounted on any metal or non-metallic surface; composition of
bumper does not matter.
• Tags can be mounted to plastic bumpers using self-threading screws.
• Metal bumpers should be pre-drilled; self-threading screws may be used.
Alternate Mounting Locations
If the exterior type tag cannot be mounted on the license plate bracket or directly on
the bumper, it may be mounted on a relatively vertical front surface of the vehicle. The
exterior tag should be mounted as close to the bumper as possible, following all guidelines regarding orientation, obstruction, and overhang given fo r bumper mounting. For
applications where the
exterior tag can be mounted on a smooth flat surface using double-sided tape.
Required Materials
Exterior tags need to be installed on a relatively flat surface. You need the following
materials to install exterior tags:

Connecting Sense Input and Sense Output Circuits
The Encompass 4H Reader has two sense input circuits and three sense output circuits
available. The sense input circuits can be used to notify the Encompass 4H Reader of
xternal events and are designed to be connected to a free-of-voltage dry contact.
e
Sense output circuits are single-pole, double-throw relays that provide normally
closed (NC) and normally open (NO) dry contacts. The relay contacts are rated at
42.2V AC peak (30 Vrms) or 60V DC at 1 A maximum. If controlling
or device requiring high current, an isolation transformer is required.
The following sections provide information to connect

Sense Input Circuits
The Encompass 4H Reader supports two sense inputs – sense input0 and sense
input1
– which requires two sense input lines for each loop sense or a total of four
sense input connections. Sense input0 is the presence detection device line and is used
to control RF power. As shown in Figure 4-16, sense input0 is through the red/green
wire pair on the I/O pigtail. The Encompass 4H Re

Encompass 4H Reader System Guide
Sense input1 allows the Encompass 4H Reader to
monitor the status of a peripheral
device. The host computer can then check the status by polling the Encompass 4H
Reader.
Figure 4-16 Sample Circuit Connections
For Encompass 4H Readers that are used with IAG protocols, the NC sense ou tput0
common is connected to the NO sense output0 common via a jumper providing a
return for sense output0 NC. Figure 4-17 shows this wiring.
