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.

Chapter 5 General Software Information Chapter 5 General Software Information This chapter provides software-related information for the Encompass® 4 Reader System. This chapter presents various software-related topics arranged in alphabetical order by subject. In addition to this chapter, see “Chapter 6 Communications Protocols” on page 6–71 and “Chapter 7 Commands” on page 7–86 for more information.
Encompass 4 Reader System Guide Command Response Conventions Like the Encompass 4 Reader commands, responses are preceded by the # character. Many Encompass 4 Reader commands respond with #Done or #Error indicating the command was or was not recognized and completed. Other commands respond with a four-character identifier followed by one or more values. Table 16 shows an example of a command/reply sequence. This example assumes that an Encompass 4 Reader with serial number SN97001P running version X.
Chapter 5 General Software Information Operating Parameters The Encompass 4 Readers maintain their operating parameters in non-volatile memory (NVRAM) so that the parameters are preserved after a power-down sequence. Caution: To save user parameter changes to NVRAM, you must send command #00 before powering down the reader. Power Fail The system maintains a power fail flag. The host transmits command #520 Display Power Fail Bit to determine if a power down has occurred.
Encompass 4 Reader System Guide Startup Upon startup, Encompass 4 Reader’s transmit a sign-on message or a boot ROM failure message. Sign-On Message If startup is successful, the sign-on message appears as follows: Model E4 Series [software version] SNYYYYYY [Copyright notice] where YYYYYY is the serial number assigned to the 4800 Reader unit being used. Serial number 000000 is the default setting and is not a valid number.
Chapter 6 Communications Protocols Chapter 6 Communications Protocols This chapter describes the communications protocols for the Encompass® 4 Reader. Introduction The Encompass 4 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.
Encompass 4 Reader System Guide Basic Protocol With basic protocol, messages sent to and from the Encompass 4 Reader and the host are transmitted without error checking. For each host transmission, the Encompass 4 Reader returns a Done or Error message to the host. When the host computer is physically close to the Encompass 4 Reader and no sources of interference exist, the basic protocol provides reliable communications.
Chapter 6 Communications Protocols Data Inquiry Protocol Data inquiry protocol is a basic protocol option that allows the host to control transmission of reader tag data. The selection of data inquiry protocol affects data mode operation. As the Encompass 4 Reader acquires tags, it buffers them but does not transmit them. Instead, the host must poll the Encompass 4 Reader for each tag by sending an ASCII CRTL-E character (hexadecimal 05).
Encompass 4 Reader System Guide When the host receives a properly framed message, it can calculate a 16-bit CRC value. The calculation is applied to the character string that immediately follows the and that ends with the character immediately preceding the first character. The transmitted CRC value can then be compared with the binary equivalent of the received characters.
Chapter 6 Communications Protocols Switch to Command Mode Request The host computer may issue command #01 Switch to Command Mode while in data mode.
Encompass 4 Reader System Guide next command, the Encompass 4 Reader will not service the new command; it will retransmit its previous message. A command/message sequence is not complete until the host updates its sequence number. Command code, a string that contains from two to four ASCII hex characters CRC value for the message [] Optional data field, an ASCII string of as many as 20 characters in length. For example, the store hardware configuration string command is #696S.
Chapter 6 Communications Protocols 4 Message sequence number KING 1302 Message data: Tag ID is shown.
Encompass 4 Reader System Guide Reader response #7Done or #7Error For some commands, the Encompass 4 Reader responds with data that relates to the command, such as T0F 0, to indicate Wiegand mode enabled for a #532 Display Wiegand Mode Status command. #7Error will be returned if host transmission is not a legal command with legal data. Timing and Synchronization The ECP is largely independent of baud rate. The timeout delays previously described are a function of baud rate.
Chapter 6 Communications Protocols before receiving an acknowledgment message, a logical NAK condition is declared, and the initiator assumes the message was received in error. In this instance, the message is retransmitted until an acknowledgment message is received. The message recipient, such as the host computer in data mode and the Encompass 4 Reader in command mode, starts a timeout counter when a character is received.
Encompass 4 Reader System Guide Receive Timeout If the Encompass 4 Reader receives a but does not receive a matching before the ECP timeout occurs, it discards the incomplete message and resets its receiver. Asynchronous Message/Command Message Collision If the Encompass 4 Reader transmits asynchronous data at the same time that the host sends a command, the Encompass 4 Reader gives priority to receiving the command.
Chapter 6 Communications Protocols To ensure this error rate is not exceeded, the host must enable parity and adhere closely to the timing specifications discussed previously in this chapter in the “Timing and Synchronization” section. CRC Calculation The CRC used by the ECP is based on a 16-bit algorithm. The algorithm, as implemented, operates on eight-bit characters, for example, seven-bit ASCII character plus one optional parity bit.
Encompass 4 Reader System Guide Example 2 shows an example of UPDCRC that does not require a lookup table.

Encompass 4 Reader System Guide Chapter 7 Commands This chapter discusses the host-transmitted commands that are used to control the Encompass® 4 Reader configuration and operation. Introduction The Encompass 4 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: The Encompass 4 Reader transmits ID codes to the host computer when the Encompass 4 Reader is in data mode. If the Encompass 4 Reader remains in the command mode with tags passing through the read zone, all tag IDs are not reported. Command Mode While the Encompass 4 Reader is in the command mode, the host computer sends commands to the Encompass 4 Reader that can be used to control the operation and configuration of the reader.
Encompass 4 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 “Download Mode” on page 7–87 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.
Chapter 7 Commands Command Group 1 – Communications Port Control Group 1 commands configure the parameters used by the Encompass 4 Reader to communicate with a host computer or terminal. These commands set baud rate, stop bits, parity, and end-of-line delay. 100N Select Baud Rate See “522 Display Communications Port Parameters” on page 7–103. Command #100N selects the reader baud rate. The factory-default setting is 9600 baud. The N variable specifies the baud rate shown in Table 17.
Encompass 4 Reader System Guide 102N Select Parity Command #102N selects the reader parity setting. The factory-default setting is parity disabled. The N variable specifies parity as shown in Table 19. See “522 Display Communications Port Parameters” on page 7–103.
Chapter 7 Commands 21 Set Date Command #21 sets the date. Enter the date in the proper format: two-digit decimal entries with no spaces between characters and using forward slashes “/” as delimiters. 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 4 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 4 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 4 Reader. 40 Transmit All ID Codes See also “530 Display RF0 Filter Status” on page 7–109. 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 4 Reader System Guide 44N Set Uniqueness Timeout See “440 Reset Uniqueness” on page 7–95. Places a time limit on the uniqueness criterion set. Refer to “410N Select Unique ID Code Criteria (Antipassback Feature)” on page 7–81. The parameter N sets the number of minutes on the timeout clock. The factory setting is two minutes (N = 1).
Chapter 7 Commands 452 Disable Tag Translation Mode (Factory Default) Command #452 disables tag translation mode. Incoming full-frame tags will be directly converted to ASCII. They will not be translated from Association of American Railroads (AAR) and American Trucking Associations (ATA) format to ASCII. Reader response: Done 453 Enable Tag Translation Mode See “534 Display Tag Translation Mode Status” on page 7–110. Command #453 enables the translation of tags in AAR and ATA formats.
Encompass 4 Reader System Guide 456 Enable eGo Plus Tag Initialization During Multi-tag Sort (Factory Default) Command #456 enables the reader to send the eGo Plus Tag initialize command as part of the multi-tag sort function. When the reader sends the eGo Plus Tag initialize command, all tags in the RF field reenter the sort process.

Chapter 8 Configuring the Encompass 4 Reader Chapter 8 Configuring the Encompass 4 Reader This chapter provides instructions for configuring the Encompass® 4 Reader, including factory configuration parameter defaults and instructions for using terminal emulation software to check and change the Encompass 4 Reader factory configuration defaults. Configuring the Reader After installing the Encompass 4 Reader, you need to configure its operating parameters.
Encompass 4 Reader System Guide As an example, a label reading 10-4002-004 indicates that this 915-MHz Encompass 4 Reader is configured with an integrated antenna, RS–232 and Wiegand communications, and reads SeGo and IAG protocol tags. Default Operating Parameter Settings Table 43 contains the factory default configuration settings for the Encompass 4 Reader operating parameters. The default configuration settings may not be the correct operating configuration settings for a specific site.
Chapter 8 Configuring the Encompass 4 Reader Table 43 Encompass 4 Reader Default Configuration Settings Parameter Setting Command Communications protocol Basic 610 Error correcting protocol (ECP) timeout 12.
Encompass 4 Reader System Guide Starting the Terminal Emulation Software You can use a PC and any terminal emulation software to enter the host commands to download flash software, configure reader operating parameters, perform diagnostics, and retrieve tag data. Most terminal emulation applications have a similar sequence for launching. To start the terminal emulation software 1. At the command prompt, type your terminal emulation start command.
Chapter 8 Configuring the Encompass 4 Reader Serial number 000000 is the default setting and is not a valid number. If this number appears in the signon message, the serial number has never been stored into reader memory. Contact TransCore Technical Support. If the flash memory checksum is not verifiable, the sign-on message appears as follows: Model [E4 BOOT] Ver 0.00 A [Copyright notice] If the failure message version number equals 0.
Encompass 4 Reader System Guide Note: The default tag read mode of the reader is the protocol(s) programmed into the reader. Table 42 shows how to determine which tag protocol(s) your Encompass 4 reader supports. Use only those test tags programmed with the correct protocol(s) for the reader. Caution To avoid damage to the Encompass 4 Reader using an external antenna, you must connect the antenna before applying power to the reader. To verify tag read capability 1.
Chapter 8 Configuring the Encompass 4 Reader If the read is unsuccessful, perform the following actions: • Ensure the tag you are using is compatible with the Encompass 4 Reader. • Using the audible circuit tester as described in “Using an Audible Circuit Tester (Buzzer)” on page 4-34, verify that the reader is capable of reading the tag in the read zone. If it is, the problem is probably in the communications between the Encompass 4 Reader and the host computer.
Encompass 4 Reader System Guide Table 45 ID Separation Commands Command Option #4100 Separation of 1 ID #4101 Separation of 2 ID #4102 Separation of 3 ID #4103 Separation of 4 ID Note: The dual-protocol Encompass 4 Reader internal timing varies depending on the operative tag read mode and the type of tag in the read field. See section “610 Select Basic Communication Protocol (Factory Default)” on page 7–114 and section “410N Select Unique ID Code Criteria (Anti-passback Feature)” on page 7–94.

Encompass 4 Reader System Guide To set the frequency range 1. Ensure that the host computer is in command mode. 2. Enter command #647XXX – where XXX is a hexadecimal value from 000 to 118 – and press ENTER. See command “647NNN Select RF Operating Frequency” on page 7–121 for a complete listing of the hexadecimal values and the corresponding frequencies. For backward compatible frequency selection, see command “642NN Select RF Operating Frequency” on page 7–118. 3.
Chapter 8 Configuring the Encompass 4 Reader Sense Inputs Both the RS–232 and RS–422 configurations used by the Encompass 4 Reader have two sense inputs — sense input0 and sense input1. The default configuration uses sense input0 as the presence detection device line. RF power is automatically turned on only when the presence detection device (loop detector or other device) detects a presence. Sense input1 is not used directly by the reader; it is used by the host computer to monitor an external device.
Encompass 4 Reader System Guide The host computer can disable the predefined sense output control by issuing command #6201 to turn sense output0 on or by issuing any of the following commands: • #6200 Turn Off Both Output Ports • #6202 Turn Off Output1, On Output0 • • #6201 Turn Off Output0, On Output1 #6203 Turn On Both Output Ports While under host control, the sense outputs are not automatically asserted when a valid tag is read.
Chapter 8 Configuring the Encompass 4 Reader To set parity 1. Ensure that the host computer is in command mode. 2. Enter command #102N and press ENTER. Communications Protocol Use the following procedures to set communications protocol. Consult sections “610 Select Basic Communication Protocol (Factory Default)” on page 7–114 through “612NN Select Error Correcting Protocol Timeout” on page 7–114 for more information.
Encompass 4 Reader System Guide Fine-Tuning and Verifying the Read Zone If the read zone is too wide or too deep for your application, it can be fine-tuned by physically adjusting the Encompass 4 Reader or external antenna mounting orientation, reprogramming the actual RF power output (#644NN Set RF Attenuation), and/ or reprogramming the RF sensitivity range (#643NN Set ATA Operating Range and #645NN Set eGo and eGo Plus Operating Range).
Chapter 8 Configuring the Encompass 4 Reader 4. Enter in command #64401 to lower the RF power by 1 dB below 2 watts (default). Press ENTER. Note: In the command #644NN, NN can be any hexadecimal value from 00 to 0A. Settings for attenuation are 1.0 dB increments over a range of 10 dB of attenuation from the maximum power setting of 2 watts at 0 dB attenuation to a minimum power level of 200 milliwatts at 10 dB attenuation. Increasing the attenuation lowers the output RF power. 5.
Encompass 4 Reader System Guide 3. Enter command #64318 or #64518 to decrease the range sensitivity seven increments below the maximum (default). Press ENTER. Note: In the command #643NN or #645NN, NN can be any hexadecimal value from 00 to 1F. The reader’s receiver becomes less sensitive to tag signals as the value of NN is lowered from the maximum sensitivity of 1F to the minimum sensitivity of 00. 4. Verify that the read zone has decreased by moving the tag through the desired read area.
