Health Limits (865 to 875 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 865 MHz.

Although not binding, other organizations such as the American National Standards Institute (ANSI) have issued similar guidelines that are more restrictive than the OSHA limits (ANSI C95.1). ANSI guidelines recommend a maximum safe

power density in mW/cm

Frequency

(in MHz)

1500

Thus, the maximum permissible exposure for general population /uncontrolled exposure at 865 MHz is 0.58 mW/cm

. The power limit is a six-minute average.

™

4/4800 Multiprotocol Reader was calculated using a maximum antenna gain of 9.5 dBi, equivalent to the antenna gain of the internal antenna.

Warning

At 2 W transmitted power and a distance of 19.7 inches (50 cm) from the read er, the maximum power density calculated was less than 0.58 mW/cm

. Install the reader at least 19.7 inches (50 cm) from the general public. Maintenance personnel must remain at least 9.1 inches (23 cm) from reader when system is operating.

The data confirms that the TransCore Encompass 4/4800 Multiprotocol Reader effectively meets OSHA requirements and thus does not represent an operating hazard to either the general public or maintenance personnel.

Encompass 4/4800 Multiprotocol Reader System Guide

The Encompass 4/4800 Multiprotocol Reader System is a full-frame 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 4/4800 Multiprotocol 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) transmitter/receiver (called the RF module), and a patch antenna.

A second version of the Encompass 4/4800 Multiprotocol Reader is designed to be used with a high-performance external antenna. These Encompass 4/4800 Multiprotocol Reader System components are contained in a highly reliable, compact, and easyto-install environmentally-sealed package. Figure 1-1 shows the front and side views of an Encompass 4/4800 Multiprotocol Reader System.

1-6

Figure 1-1 Encompass 4/4800 Multiprotocol Reader System Front and Side Views

How It Works

The Encompass 4/4800 Multiprotocol Reader System directs the RF module to generate an RF signal, which is broadcast through the internal or external antenna. Entering the Encompass 4/4800 Multiprotocol 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 4/4800 Multiprotocol Reader System. The Encompass 4/4800 Multiprotocol Reader System 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.

Page 29

Licensing Requirements

An FCC license provides the user with the legal authorization to operate the Encompass 4 on the licensed frequencies at the site specified in the license. Only an authorized installer or service technician can set the RF frequency of the Encompass 4/4800 Multiprotocol Reader System to the frequency specified in the FCC site license. No end-user-operated controls exist on the Encompass 4/4800 Multiprotocol Reader System.

The FCC license also provides the user with protection and authorization to maintain the system should any other RFID product be used in the licensed area after the Encompass 4/4800 equipment is installed.

Users of the Encompass 4/4800 Multiprotocol Reader System in the United States must obtain a license from the FCC. The authorized frequency band for this product in the United States is 912.5 to 919 MHz.

The user is responsible for filing the FCC license according to FCC regulations, but the TransCore dealer will provide assistance and support as necessary to complete these forms.

Overview

Chapter 2

Developing the Site Plan

This chapter discusses site plan development for installing the

Encompass

Developing a site plan provides the foundation for the site’s system design and es tablishes the following system configuration parameters:

• Number and general location of primary components

• Number of different radio frequencies required

Gathering relevant site information is crucial before applying for Federal Communications Commission (FCC) approval and ordering and installing Encompass 4/4800 Multiprotocol Reader(s) and tags.

Also, consider the following factors when developing a site plan:

4/4800 Multiprotocol Reader System.

• Type of tags used in the facility

• Reader and/or antenna and tag alignment

• Site layout and traffic flow

• Encompass 4/4800 Multiprotocol Reader and/or antenna mounting requirements

• Encompass 4/4800 Multiprotocol Reader electrical requirements

• Encompass 4/4800 Multiprotocol Reader communications requirements

These factors provide relevant information regarding each site’s physical and electromagnetic environment and the conditions under which the system must perform.

Reading of Mixed Population Tags

The Encompass 4/4800 Multiprotocol Reader reads the American Trucking Association (ATA) and International Organization for Standardization (ISO) read-only tags, whether powered by battery or beam, or application-specific integrated circuit (ASIC)-based tags with Intellitag technology. 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.

2-3

Page 34

Encompass 4/4800 Multiprotocol Reader System Guide

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 orientation and configuration, type of read-only tag, ratio of backscatter cross-section of the tags, and whether the tag is battery- or beam-powered.

Reader and Tag Alignment

The position of the Encompass 4/4800 Multiprotocol Reader and placement of the tag on the vehicle must be compatible. Also, consider any existing tagged vehicles now using the facility to determine the optimal Encompass 4/4800 Multiprotocol Reader location and orientation at the site.

Note: If any of the vehicles using your facility already have tags, such as those used in toll applications, contact TransCore at 1-800-755-0378 for information about mixed-tag installations before you plan tag type, location, and programming.

Three primary criteria must be satisfied to achieve the highest read reliability:

• Polarization of the tag and the Encompass 4/4800 Multiprotocol Reader must be

aligned in the same direction

— both horizontal.

• The installed tag must be in a direct, unobstructed line of sight to the Encompass

4/4800 Multiprotocol Reader .

• T ags desig ned to be mo unted in a vehicle wind shield must be mo unted in the veh i-

cle’s windshield, and tags designed to be mounted on the exterior surface of the vehicle must be mounted on the exterior surface of the vehicle.

Caution

A tag may not be reliably read unless the preceding criteria are met.

2-4

Page 35

Developing the Site Plan

Polarization

The polarization of the tag must be aligned in the same direction as the Encompass 4/4800 Multiprotocol Reader, as shown in Figure 2-1.

Note: Matching the tag and antenna polarization is critical to obtain optimal system performance.

Encompass 4/4800 Multiprotocol Reader System Guide

Unobstructed Line of Sight

For optimum readability, install the Encompass 4/4800 Multiprotocol Reader and the vehicle’s tag so that when the vehicle approaches the Encompass 4/4800 Multiprotocol Reader, the tag is directly facing the reader and the line of sight is clear between the Encompass 4/4800 Multiprotocol Reader and the tag. If a fence or barrier is between the tag and the reader, the Encompass 4/4800 Multiprotocol Reader cannot reliably read the tags. Figure 2-2 illustrates possible installation locations of an Encompass 4/4800 Multiprotocol Reader in relation to a tag’s mounting location on a vehicle. If the tags are not in the recommended location, reliable optimum operation requires lower vehicle speeds.

Developing the Site Plan

If the Encompass 4/4800 Multiprotocol Reader is installed on a pole or wall to the left

of the vehicle, optimal tag position is on the left side of the vehicle as illustrated in Figure 2-3.

Figure 2-3 Typical Tag Positions for U.S. Driver’s Side Reader

If an Encompass 4/4800 Multiprotocol Reader is installed on a pole or wall to the right of the vehicle, optimal tag position is on the right side of the vehicle as illustrated in Figure 2-4.

Figure 2-4 Typical Tag Positions for U.S. Passenger’s Side Reader

2-7

Page 38

Encompass 4/4800 Multiprotocol Reader System Guide

If the Encompass 4/4800 Multiprotocol Reader is installed in an overhead location, optimal tag position is in the top center of the windshield in the area behind the rear view mirror or on the vehicle’s front license plate or center bumper as illustrated in Figure 2-5.

Figure 2-5 Typical Tag Positions Used with Overhead Reader

Note: Metallized coatings on some vehicle windshields and windows shield the RF energy emitted by the Encompass 4/4800 Multipr otocol Reader and may cause tags to be misread. 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 the vehicle.

Refer to Chapter 3 “Choosing, Installing, and Removing Tags” for more detailed information on tag positioning.

age to a single lane width

• Low antenna profile

Antenna and Tag Alignment

The position of the antenna connected to the Encompass 4/4800 Multiprotocol Reader and placement of the tag on the vehicle must be compatible. Also, consider any existing tagged vehicles now using the facility to determine the optimal Encompass 4/4800 Multiprotocol Reader antenna location and orientation at the site.

Three primary criteria must be satisfied to achieve the highest read reliability:

• Polarization of the tag and the Encompass 4/4800 Multiprotocol Reader antenna

must be aligned in the same direction — both horizontal or both vertical.

• The installed tag must be in a direct, unobstructed line of sight to the Encompass

4/4800 Multiprotocol Reader antenna.

• T ags desig ned to be mo unted in a vehicle wind shield must be mo unted in the veh i-

cle’s windshield, and tags designed to be mounted on the exterior surface of the vehicle must be mounted on the exterior surface of the vehicle.

Caution

A tag may not be reliably read unless the preceding criteria are met.

Polarization

The polarization of the tag must be aligned in the same direction as the antenna connected to the Encompass 4/4800 Multiprotocol Reader, as shown in Figure 2-1.

2-10

Note: Matching the tag and antenna polarization is critical to obtain optimal system performance.

Figure 2-1 Horizontal and Vertical Tag Orientation

A horizontally oriented antenna cannot read a vertically oriented tag and vice versa.

Unobstructed Line of Sight

For optimum readability, install the Encompass 4/4800 Multiprotocol Reader antenna and the vehicle’s tag so that when the vehicle approaches the antenna, the tag is directly facing the antenna and the line of sight is clear between the antenna and the tag. If a fence or barrier is between the tag and the antenna, the antenna cannot reliably read the tags. Figure 2-2 illustrates possible installation locations of an Encompass 4/ 4800 Multiprotocol Reader antenna in relation to a tag’s mounting location on a vehicle. If the tags are not in the recommended location, reliable optimum operation requires lower vehicle speeds.

Site Layout and Traffic Flow

The following site layout and traffic flow considerations are critical when determining Encompass 4/4800 Multiprotocol Reader installation locations:

• The Encompass 4/4800 Multiprotocol Reader read zone

• Other Encompass 4/4800 Multiprotocol Reader units and antennas in the area

• Lane configurations

• Reflection, refraction, and diffraction of RF signals

• Existing signal interference at the site

2-12

Page 43

Developing the Site Plan

The Encompass 4/4800 Multiprotocol Reader Read Zone

The Encompass 4/4800 Multiprotocol 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 4/4800 Multiprotocol 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

• Mounting method used (pole or wall mount) of the antenna

• Mounting location (overhead or side mount) of the antenna

• Height from the ground and mounting angle of the antenna

• Indoor or outdoor location

• RF output attenuation

• Range discrimination setting

• Other sources of interference and reflection

The Encompass 4/4800 Multiprotocol 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 antenna becomes misaligned or some nearby structure is added or removed, system operation can be seriously affected.

The external antenna 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 antenna 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 8-20.

Other Encompass 4/4800 Multiprotocol Readers in the Area

Sites with more than one Encompass 4/4800 Multiprotocol Reader in proximity should have them configured with a frequency separation of at least 2 MHz from adjacent readers. If more than one Encompass 4/4800 Multiprotocol Reader is in a sideby-side or multiple lane application, the frequencies should be staggered. Also, Encompass 4/4800 Multiprotocol Readers may not operate accurately if they directly face each other or are positioned back-to-back.

2-13

Page 44

Encompass 4/4800 Multiprotocol Reader System Guide

If more than one Encompass 4/4800 Multiprotocol Reader and antenna is in a side-byside or multiple lane application, the frequencies should be staggered. Also, Encompass 4/4800 Multiprotocol Readers may not operate accurately if the antennas directly face each other or are positioned back-to-back.

T a ble 2-1 shows examples of staggered reader frequencies in a site with up to 14 readers.

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 4/ 4800 Multiprotocol 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 metallic surfaces. RF signals may also be partially reflected by nonconducting materials such as dirt, wood, ice, asphalt, and concrete. When nonconducting materials in the system environment become wet, they increase reflection of RF signals.

The Encompass 4/4800 Multiprotocol Reader and/or antenna mounting location, aiming, and range control adjustment, 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 infor- mation.

2-19

Encompass 4/4800 Multiprotocol Reader System Guide

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 stations, or power lines can interfere with the optimal operation of the system. The magnetic 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 4/4800 Multiprotocol Reader and/or antenna. In some cases, changing the operating frequency of the Encompass 4/4800 Multiprotocol Reader may provide a simple solution. Readers in proximity should have at least a 2 MHz frequency separation. See

“Other Encompass 4/4800 Multiprotocol Readers in the Area” on page 2-13. Strong

RF sources of any frequency, in proximity to the tag, can preclude the tag receiving the reader interrogation. See Chapter 9, “Troubleshooting and Maintenance.”

Electrical and Communications Requirements

All construction work at the site must be completed before installing the Encompass 4/4800 Multiprotocol Reader . Electrical and communications cables should be installed according to all applicable local and federal building code requirements. Specific instructions for positioning and installing the Encompass 4/4800 Multiprotocol Reader are discussed in Chapter 4, “Installing the Encompass 4/4800 Multiprotocol

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 terminal 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 4/4800 Multiprotocol Reader installation site. Table 2-1 lists accessory kits available for cabling options based on your site’s requirements.

Electrical Power

A dedicated electrical power supply must be present at the site and available to the Encompass 4/4800 Multiprotocol Reader at all times. The power must be 16-20V AC or 16-28V DC. A step-down transformer is available (North America only) to convert a 120V AC duplex wall outlet with ground to 18V AC, as is a step-up transformer to convert a low-voltage 12V AC outlet to 18V AC. Consult your local and national electrical codes for installation and safety requirements.

Note: Encompass 4/4800 Multiprotocol Readers installed outside North America require a locally supplied transformer.

If 18V AC or 18V DC power is available, the transformer option is unnecessary. TransCore offers a Class C transformer accessory kit (part number 76-1620-005) for

sites where 110V AC is available. It is the installer’s responsibility to supply conversion equipment and wiring for other voltages. T a ble 2-2 contains power supply current requirements.

Power Extension

Use Table 2-3 to determine the correct cable size according to the American Wire Gauge (AWG) standard for the necessary length of extension cable. The numbers in the first row of the table indicate cable size for the approximate cable length .

Note: If the cable is close to the ma xim u m len gth, measure voltage at the Encompass 4/4800 Multiprotocol Reader with RF ON to ensure voltage does not drop below 16V. A drop in voltage below 16V causes a reduction in read range and possible damage to internal electronics as well as unreliable operation.

Intellitag Data Format

The memory of Intellitag-based tags consists of 128 bytes of non-volatile read/write memory. Portions of tag data, such as the tag serial number, manufacturing location code, and tag hardware type, are programmed at the factory and locked. The tag memory layout may be programmed by the end user and may be ke pt unlocked if desired.

Of the 128 bytes of memory, 12 bytes are programmed and locked at the factory and 116 bytes of user memory are available to be formatted and locked as required by the application. Six bytes of the available 116 bytes of user memory are used for defining tag memory layout.

Tags can be programmed in Wiegand formats with 26 to 54 bits. Users who choose this tag data format must complete a Wiegand format worksheet — attached to the Encompass 4/4800 Multiprotocol Reader order entry form — indicating the data to be programmed into the tags.

Installing eGo Windshield Sticker Tags

eGo Windshield Sticker Tags are designed to be attached by a semi-permanent adhesive to the interior surface of nonmetallic windshields 0.190 to 0.230 inches (4.82 to

5.84 mm) in thickness. For optimum performance, you must install the tag at least 2 inches (5 cm) from the metal in the windshield frame and 0.75 inch (1.9 cm) from the rearview mirror support post. Detailed instructions are found in the pocket guide "Quick and Easy Installation Instructions for Windshield Sticker Tag."

Some vehicles have a tinted area across the top of the windshield. If the tint is conductive, it can interfere with reading the tag. If a windshield has this conductive tint, the tag must be installed at least 2 inches (5 cm) below this tinted area.

Some vehicle windshields contain a metallic treatment that could prevent an interior windshield-mounted tag from being read. However, many of these metallized windshields have areas that are not metallized. On a vehicle without open areas in its metallized windshield, you might need to install an Encompass 4/4800 Multiprotocol Reader-compatible license plate tag on the vehicle. See the section “Installing eGo

License Plate Tags” on page 3-9 and the section “Installing ATA License Plate Tags” on page 3-15. Contact TransCore for more information. See the section “Technical Support” on page 9-7.

eGo Plus Sticker T ags are posit ioned and installed similarly to eGo W indshield Sticker T ags. Detailed instructions are found in the pocket guide "Quick and Easy Installation Instructions for the eGo

Plus Sticker Tag."

Page 65

Choosing, Installing, and Removing Tags

To install the eGo Windshield Sticker Tag

1. Determine the tag installation location for the vehicle using the placement guidelines in the section “Positioning eGo Windshield Sticker Tags” on page 3-7.

2. Thoroughly clean the interior surface of the windshield behind and around the rearview mirror where the tag will be located.

3. Dry the tag location area thoroughly using a clean, dry cloth.

4. Remove the paper backing from the tag to expose the adhesive.

Caution

Ensure that the tag is correctly located before touching it to the glass. Once the sticker tag is applied to the glass, it cannot be moved without damage to the tag.

5. Holding the sticker tag by its edges, position the tag in the correct area of the windshield (determined in Step 1), making sure the tag is oriented horizontally and is at least two inches (5 cm) from the windshield frame and 0.75 inch (1.9 cm) from the mirror post.

6. Press the sticker tag firmly against the glass and gently rub over the entire tag surface. Ensure that no air bubbles remain between the sticker tag and the windshield.

Removing eGo Windshield Sticker Tags

Removing eGo Windshield S ticker Tags requires the use of a razor blade or equivalent tool. The tag is inoperable once removed.

Installing eGo License Plate Tags

Metallized coatings on some vehicle windshields and windows absorb the RF energy emitted by the Encompass 4/4800 Multiprotocol Reader, thus causing tags to be misread. You must use exterior license plate tags 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 4/4800 Multiprotocol 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)

3-9

Page 66

Encompass 4/4800 Multiprotocol Reader System Guide

• Optional TransCore Exterior Tag Accessory Kit (19077-01). This kit contains

tamper-resistant mounting screws and wrench.

• eGo License Plate Tag

Positioning eGo License Plate Tags

The eGo License Plate Tag (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.

Choosing, Installing, and Removing Tags

eGo License Plate Tag Installation Procedures

To mount the eGo LPT

1. Remove the screws from the license plat e area of your front bumper (Figu re 1). 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.

Figure 3-7 Correct Mounting Location for LPT

2. Position the LPT so that it is within 18 inches (46 cm) of the center of the front bumper as shown by the shaded area in Figure 3-7. If your vehicle’s license plate mounting area is more than 18 inches (46 cm) from the center, you may need to select an alternate location to mount the tag. Contact your tag agency if your vehicle requires an alternate mounting location for the LPT.

Installing Interior ATA Tags

Interior ATA-protocol tags are installed using hook-and-loop material or double-sided tape attached to the tag and to the windshield. When using hook-and-loop material, the loop material should be applied to the back of the tag and the hook material should be applied to the windshield. After the tag is installed, it can be removed easily and used in any vehicle that has corresponding hook material affixed to the windshield.

Note: Installing interior tags using double-sided tape results in a semipermanent attachment; the tag will be more difficult to remove than one installed using hook and loop material.

Interior ATA-protocol tags may be ordered from the factory with hook-and-loop material or double-sided tape already applied to the tag. The adhesive on this material is specially formulated for temperature extremes inside vehicles.

Required Materials

You will need the following materials to install interior tags:

Choosing, Installing, and Removing Tags

• Rubbing alcohol or 50/50 isopropyl alcohol and water

• Sponge and dry cloth

• Interior tags with two strips of factory-installed hook-and-loop material or fac-

tory-installed double-sided tape attached

Positioning ATA Tags

Interior ATA-protocol tags can be installed on the driver’s side, passenger’s side, or upper center of the vehicle’s windshield, depending on the Encompass 4/4800 Multiprotocol Reader’s position. See “Reader and Tag Alignment” on page 2-4.

Tags should be mounted consistently in all vehicles using a particular Encompass 4/ 4800 Multiprotocol Reader facility.

Interior Driver’s or Passenger’s Side

TransCore designed interior ATA-protocol tags for installation inside the vehicle, typically on the driver’s side of the windshield. Install the tag in the upper corner, at least two inches (5 cm) from the metal window post, as shown in Figure 3-10.

3-13

Figure 3-10 Driver’s or Passenger’s Side (U.S.) Interior Windshield Tag Location

Interior Center Windshield

You may also install ATA tags on the upper center portion of the windshield. Position the tag as closely as possible to the windshield’s upper center, behind the rearview mirror. The top edge of the tag should be approximately one inch (2.5 cm) below the base of the mirror, or above the base if enough room is available for the tag to be two inches (five cm) from metal around the windshield, as shown in Figure 3-11.

3-14

Figure 3-11 Upper Center Interior Windshield Tag Location

ATA Interior Tag Installation Procedures

Perform the following steps to install interior tags:

1. Clean the tag installation area on the interior surface of the windshield with rubbing alcohol.

2. Dry the area thoroughly using a clean, dry cloth.

3. Remove the clear backing from the two strips of hook-and-loop material on the back of the tag (Figure 3-12) or from the double-sided tape.

Page 71

Choosing, Installing, and Removing Tags

Figure 3-12 Hook-and-Loop Material on Interior Tag

4. Position the tag over the correct area of the windshield, making sure that the tag and reader orientation are the same (horizontal or vertical).

5. Press the tag firmly against the glass.

Removing Interior ATA Tags

To remove an interior ATA-protocol tag installed using hook-and-loop material, simply pull the tag away from the windshield.

To remove an interior ATA-protocol tag installed using double-sided tape, slowly pry off the tag with a thin tool, such as a putty knife.

Installing ATA License Plate Tags

Metallized coatings on some vehicle windshields and windows absorb the RF energy emitted by the Encompass 4/4800 Multiprotocol Reader, thus causing tags to be misread. Use exterior license plate tags on vehicles with metallized coatings on 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 Encomp ass 4/4800 Multiprotocol Reader should be adjusted accordingly when an exterior tag is installed on a license plate, or the read zone will be reduced.

3-15

Page 72

Encompass 4/4800 Multiprotocol Reader System Guide

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 license plate-mount tag

• 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.

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 3-13.

Figure 3-13 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 license plate tag

1. Position the tag so that the holes in the tag are on the bottom edge and the tag is within 18 inches (.45 m) of the center of the front bumper as illustrated by the shaded area in Figure 3-14.

Note: When mounting an exterior tag on heavy trucks or tractors, the tag mu st be mounted within 1.5 inches (3.81 cm) of the top of the bumper.

Figure 3-14 Correct Exterior Tag Placement

2. Line up the holes in the tag as follows:

• If mounting the tag to a license plate or license 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 the 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 3-14.

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 3-15.

Choosing, Installing, and Removing Tags

Figure 3-17 Spacer Positioned Behind Tag

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 su rface 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 for bu mper mounting. For applications where the integrity of the mounting surface cannot be compromised, 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:

• Rubbing alcohol, 50/50 isopropyl alcohol and water, or solvent/cleaner for metal

• Sponge and dry cloth

• Exterior tag with the double-sided adhesive tape attached

3-19

Encompass 4/4800 Multiprotocol Reader System Guide

Installation Procedures Using Tape

To install the tag on a metal or plastic bumper

1. Clean and degrease the tag installation area of the vehicle bumper with solvent/ cleaner.

2. Dry the area thoroughly using a clean, dry cloth.

3. Remove the backing from the double-sided tape on the back of the tag, as shown in Figure 3-18.

Figure 3-18 Exterior Tag with Double-Sided Tape

4. Position the tag over the installation area, making sure that the tag and Encompass 4/4800 Multiprotocol Reader orientation are the same (horizontal or vertical).

5. Press the tag firmly against the bumper.

Installation Procedures Using Blind Rivets

To install an exterior tag using blind rivets through the tag’s installation tabs

1. Position the tag on the bumper in the installation area and mark the hole positions of the tag’s installation tabs on the bumper.

2. Follow the rivet manufacturer’s instructions to drill holes in the bumper for rivets.

3. If the rivet head is smaller than the tag installation holes and can be pulled through the holes, use a small washer to secure the rivet through the tag.

Removing Exterior Tags

To remove an exterior tag installed with rivets, follow the rivet manufacturer’s instructions to remove the rivets.

Mounting the Antenna

If you are using the Encompass4/4800 Multiprotocol Reader that requires an external antenna in permanent installations, the antenna should be positioned as close as possible to the Encompass 4/4800 Multiprotocol Reader. Long cable runs increase system sensitivity to noise. See Table 2-6 on page 2-20 for maximum RF cable lengths.

This section provides guidelines for mounting antennas.

Mounting the Antenna Curb-Side

Some site designs, for example those with curb-side antennas, require that the antenna be mounted on a round pole. The pole must be a minimum of 2 inches (5 cm) in diameter and should extend approximately 8 feet (2.4 m) above the pavement level. The pole must be installed according to local building codes.

Procedures

Use the following guidelines to mount an antenna on a curb-side round pole.

To mount the antenna to a curb-side pole

1. Follow the manufacturer’s directions to attach the antenna assembly to the pole approximately 8 feet (2.4m) above the pavement surface.

2. Tighten slightly so that you can adjust the antenna left or right but not so slightly that the antenna slides down the pole.

3. Adjust the assembly by pointing the antenna to the middle of the area where tags will be read, and while in this position, tighten all screws and fastenings slightly.

Note: Adjust the antenna to provide the most direct line of sight to the tags.

Figure 4-14 illustrates front and top views of a pole-mounted antenna with the approx imate measurements for sites where ta gs wou ld be mounted on the interior driver -side windshield. eGo Windshield S ticker Tags may be mounted on the interior upper center or upper driver-side corner of the windshield.

Note: Determine the read zone before you tighten all screws and straps permanently. Refer to the section “Marking the Read Zone” on page 4-32.

After mounting the antenna, you must connect it to the Encompass 4/4800 Multiprotocol Reader. Follow the procedures described previously in the section “Connecting the

Antenna” on page 4-6.

Caution

To avoid damage to the Encompass 4/4800 Multiprotocol Reader, you must connect the antenna before applying power to the reader.

Note: The dimensions in Figure 4-14 are for demonstration purposes only and are approximations for sites using the older ATA-type tags. Actual dimensions vary as lane geometry and tag style varies from site to site. Adjust the antenna to match site and tag mounting positions to provide the most direct line of sight to the tags.

Mounting the Antenna Overhead

Some site designs require that the antenna be mounted in an overhead location.

Procedures

To mount the antenna in an overhead location

1. Follow the manufacturer’s directions to attach the antenna assembly to the overhead location at approximately 18 feet above the pavement surface.

2. Tighten slightly so that you can adjust the antenna up and down but not so slightly that there is a risk of the antenna falling.

3. Adjust the assembly by pointing the antenna to the middle of the area where tags will be read, and while in this position, tighten all screws and fastenings slightly.

Note: Adjust the antenna to provide the most direct line of sight to the tags.

For example, in toll lanes the Universal Toll Antenna (UTA) would be installed approximately 15 degrees from the verticle.

Figure 4-15 illustrates an overhead-mounted antenna with approximate measurements

for the read zone.

Note: Determine the read zone before you tighten all screws and straps permanently. Refer to the section “Marking the Read Zone” on page 4-32.

After mounting the antenna, you must connect it to the Encompass 4/4800 Multiprotocol Reader. Follow the procedures described previously in the section “Connecting the

Antenna” on page 4-6.

Connecting the Power Supply

To connect the Encompass 4/4800 Multiprotocol Reader to a low-voltage AC power supply follow the procedures described previously in the section “Connecting the AC Power Supply” on page 4-6.

To connect the Encompass 4/4800 Multiprotocol Reader to a low-voltage DC power supply follow the procedures described previously in the section “Connecting the DC Power Supply” on page 4-7.

After mounting the Encompass 4/4800 Multiprotocol Reader and antenna, if required, you must connect the reader to a dedicated 16 to 20V AC or 16 to 28V DC power supply.
