Chapter 1 Introduction Chapter 1 Introduction System Guide Organization This guide provides site planning and testing, installing, and operating instructions for TransCore’s Encompass 4H Reader System. Please read this entire manual before installing the Encompass 4H Reader System. System Description The Encompass 4H Reader System is a dual-protocol reader supporting the low-cost, high-performance SeGo radio frequency identification (RFID) technology.
Encompass 4H Reader System Guide Figure 1 Encompass 4H Reader System Front and Side Views Tags The Encompass 4H Reader System has the capability to read TransCore SeGo, ATA and IAG protocol tags, and ISO-compliant read-only full- and half-frame tags. How It Works The Encompass 4H Reader System directs the RF module to generate an RF signal, which is broadcast through the integrated antenna.
Chapter 2 Developing the Site Plan 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 establishes the number and general location of primary components.
Encompass 4H Reader System Guide • The installed tag must be in a direct, unobstructed line of sight to the Encompass 4H Reader. • Tags designed to be mounted in a vehicle windshield must be mounted in the vehicle’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.
Chapter 2 Developing the Site Plan the Encompass 4H Reader cannot reliably read the tags. Figure 3 illustrates possible installation locations of an Encompass 4H 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.
Encompass 4H Reader System Guide Figure 4 Typical Tag Positions for U.S. Driver’s Side Reader If an Encompass 4H 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 Figure 6 Typical Tag Positions Used with Overhead Reader 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 misread. Many metallized windshields have areas that are not metallized in which the tag can be placed and reasonable results achieved.
Encompass 4H Reader System Guide • 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
Chapter 2 Developing the Site Plan Gate with Center Island Configuration Figure 7 illustrates a typical gate application with the Encompass 4H 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.
Encompass 4H Reader System Guide Parking Garage with Ticket Island Configuration Figure 8 illustrates a parking garage application with each Encompass 4H Reader mounted on the ticket island to read tags mounted on the inside center windshield or on the center front vehicle bumper. The Encompass 4H Reader placement may require the vehicle to stop before the gate opens.
Chapter 2 Developing the Site Plan Figure 9 Overhead Installation 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. 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.
Encompass 4H Reader System Guide Existing Signal 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.
Chapter 2 Developing the Site Plan Electrical Power A dedicated electrical power supply must be present at the site and available to the Encompass 4H 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.

Encompass 4H Reader System Guide Chapter 6 Communications Protocols This chapter describes the communications protocols for the Encompass® 4H Reader. Introduction The Encompass 4H Reader supports the following communications protocols: • Basic • Error correcting protocol (ECP) • Data inquiry The following protocol information provides reference information relevant to developing host software.
Chapter 6 Communications Protocols Basic Protocol With basic protocol, messages sent to and from the Encompass 4H Reader and the host are transmitted without error checking. For each host transmission, the Encompass 4H Reader returns a Done or Error message to the host. When the host computer is physically close to the Encompass 4H Reader and no sources of interference exist, the basic protocol provides reliable communications.
Encompass 4H Reader System Guide Reader for each tag by sending an ASCII CRTL-E character (hexadecimal 05). The Encompass 4H Reader transmits one message (tag ID or report data) for each CTRL-E it receives until the buffer is empty. Each tag request message sent by the host consists only of the CTRL-E character; no som or eom characters are sent. Encompass 4H Reader data transmission (tag ID and report data) format is the same as for basic protocol.
Chapter 6 Communications Protocols match, the recipient assumes the message was received in error, and transmits a NAK message response. End-of-message characters (ASCII CR and LF). The system includes both a carriage return (CR) and line feed (LF) to facilitate the use of terminals and printers. If the host receives a character in the middle of a data message, the message in progress is aborted.
Encompass 4H Reader System Guide The ECP format is as follows: where Start-of-message (ASCII # character) Sequence number generated by the host computer separately from that appearing in data messages transmitted by the Encompass 4H Reader Switch to command mode (ASCII characters 01) End-of-message character (ASCII CR) CRC value for the message Host Transmission The host computer initiates synchronous communications between

Chapter 6 Communications Protocols Timing and Synchronization The ECP is largely independent of baud rate. The timeout delays previously described are a function of baud rate. The Encompass 4H Reader supports an ECP timeout, which applies equally to both transmit and receive. The receiver’s minimum timeout delay equals the time to transmit/receive the longest anticipated message at the current baud rate setting.
Encompass 4H Reader System Guide without the receipt of an , the message acquisition is aborted (reset), and the receiver waits for the next character. If the message recipient receives a second character before an character, the message acquisition is aborted (reset), and retransmission of the previous message is assumed to be underway. These strategies allow for recovery during periods when communications are marginal or completely lost.
Chapter 6 Communications Protocols Host-Addressed Failure Conditions The host computer addresses the following failure conditions. Illegal or Wrong Sequence Number If the host detects an illegal or wrong sequence number in a reader response, it retransmits the command with the same sequence number. If the host detects an illegal sequence number in an asynchronous reader transmission, it sends a NAK message.
Encompass 4H Reader System Guide The Encompass 4H Reader accepts four ASCII < ` > characters (60 hex) as a wild card CRC value in lieu of a valid four-character CRC value to facilitate testing and diagnostic checkout. The Encompass 4H Reader implements the algorithm with a 512-byte lookup table to reduce the processing overhead requirements.

Encompass 4H Reader System Guide Chapter 7 Commands This chapter discusses the host-transmitted commands that are used to control the Encompass® 4H Reader configuration and operation. Introduction The Encompass 4H Reader is delivered from the factory with specified default settings that determine how the reader operates. Commands transmitted by the host computer can change the default settings and control additional features.
Chapter 7 Commands Note: ID codes are transmitted to the host computer when the Encompass 4H Reader is in data mode. If the Encompass 4H Reader remains in the command mode with tags passing through the read zone, all tag IDs are not reported. Command Mode While the Encompass 4H Reader is in the command mode, the host computer sends commands to the Encompass 4H Reader that can be used to control the operation and configuration of the reader.
Encompass 4H Reader System Guide Command List Reader commands are divided into groups based on primary function. The following sections provide information about each command in command number order. Refer to “Command Group 6 – Reader Control Functions” on page 7–101 for listings of commands in numerical and alphabetical order. In the following text, the symbols < and > represent variable message data. These symbols are not part of the message syntax.

The entry format is as follows: 21MM/DD/YY where MM represents the month (01 to 12). DD represents the day (01 to 31). YY represents the last two digits of the year (00 to 99). / is the date delimiter.
Encompass 4H Reader System Guide 30N Append Time and Date Selection Command #30N selects the option of appending the time and date to transmitted IDs, error messages, presence without tag reports, and input status change reports. The factory default setting is time and date appended (Command #302). The reader returns an Error message if its tag buffer contains data. The reset reader command #63 may be transmitted to clear the buffer; however, tag ID data will not be reported.
Chapter 7 Commands The reader transmits messages with auxiliary information appended as: % where % separates the auxiliary information and signals the host computer that auxiliary information is appended xx reader ID. Value can be set with command #60NN - auxiliary information delimiter y antenna number. Value fixed at 0 zz number of reads (00 to FF hexadecimal) of the previous tag q current status of input0 and input1 (0 to 3).
Encompass 4H Reader System Guide Command Group 4 – ID Filtering Group 4 commands set criteria for filtering (buffering or discarding) ID codes. These commands are useful for eliminating duplicate ID codes and selecting the type of tags read by the Encompass 4H Reader. 40 Transmit All ID Codes See also “530 Display RF0 Filter Status” on page 7–97. Command #40 instructs the reader to transmit all IDs without regard for uniqueness.
Chapter 7 Commands Item 3 Third-most recently acquired ID Item 4 Fourth-most recently acquired ID When the uniqueness filter is set to separation of one ID, the newly acquired ID is transmitted only if it is different from the first item. Separation of two IDs allows transmission if the new ID is different from Items 1 and 2 in the comparison register. Separation of three and four IDs transmit the new ID only if it is different from the first three and the first four items, respectively.
Encompass 4H Reader System Guide 44N Set Uniqueness Timeout See “440 Reset Uniqueness” on page 7–83. Places a time limit on the uniqueness criterion set.
