Encompass 4 Reader System Guide Chapter 2 Developing the Site Plan This chapter discusses site plan development for installing the Encompass® 4 Reader System. Overview Note: In this section, unless specifically stated, “Encompass 4 Reader” applies both to the Encompass 4 Reader with integrated antenna and Encompass 4 Reader with external antenna.
Chapter 2 Developing the Site Plan Reader, Tag, and Antenna Alignment The position of the Encompass 4 Reader, antenna, 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 Reader, antenna, and tag location and orientation at the site.
Encompass 4 Reader System Guide Polarization The polarization of the tag must be aligned in the same direction as the Encompass 4 Reader, as shown in Figure 2. Note: Matching the tag and antenna polarization is critical to obtain optimal system performance.
Chapter 2 Developing the Site Plan Figure 3 Encompass 4 Reader Location Relative to Tag Position If the Encompass 4 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 4. Figure 4 Typical Tag Positions for U.S.
Encompass 4 Reader System Guide If an Encompass 4 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 5. Figure 5 Typical Tag Positions for U.S.
Chapter 2 Developing the Site Plan Note: Metallized coatings on some vehicle windshields and windows shield the RF energy emitted by the Encompass 4 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 exteriortype tags on the exterior of the vehicle.
Encompass 4 Reader System Guide AA3140 PCB Log Periodic Appropriate for installations with the following requirements and conditions: • 845 to 950 MHz operation • Exposure to harsh environments • Maximum coverage at close range (<20 ft [6.
Chapter 2 Developing the Site Plan • RF output attenuation • Range discrimination setting • Other sources of interference and reflection The Encompass 4 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.
Encompass 4 Reader System Guide Gate with Center Island Configuration Figure 7 illustrates a typical gate application with the Encompass 4 Reader units positioned on a center island to read tags mounted on the inside windshield on the 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.
Chapter 2 Developing the Site Plan Parking Garage with Ticket Island Configuration Figure 8 illustrates a parking garage application with each Encompass 4 Reader mounted on the ticket island to read tags mounted on the inside center windshield or on the center front vehicle bumper. The Encompass 4 Reader placement may require the vehicle to stop before the gate opens.
Encompass 4 Reader System Guide Figure 9 Overhead Installation Lane Configurations Using an External Antenna TransCore recommends that traffic be guided through a controlled lane to consistently obtain accurate tag readings and to prevent physical damage to the Encompass 4 Reader and antenna. 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.
Chapter 2 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 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.
Encompass 4 Reader System Guide Electrical Power A dedicated electrical power supply must be present at the site and available to the Encompass 4 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.
