2 Developing the Site Plan
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 Reader and Tag Alignment The position of the Encompass 4H 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 4H Reader location and orientation at the site.
Developing the Site Plan Polarization The polarization of the tag must be aligned in the same direction as the Encompass 4H Reader, as shown in Figure 2-1. Note: Matching the tag and reader polarization is critical to obtain optimal system performance.
Encompass 4H Reader System Guide 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.
Developing the Site Plan If the Encompass 4H 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 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 2-4. Figure 2-4 Typical Tag Positions for U.S.
Encompass 4H Reader System Guide If the Encompass 4H 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 4H Reader and may cause tags to be misread.
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.
Encompass 4H Reader System Guide 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 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.
Developing the Site Plan Parking Garage with Ticket Island Configuration Figure 2-7 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.
Encompass 4H Reader System Guide Figure 2-8 Overhead Installation 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.
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 4H Reader System Guide 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/line drivers over copper wire are used for communications between the Encompass 4H Reader and the host.
Developing the Site Plan Note: When extending the Wiegand interface, use a three-pair cable such as Belden 2919. Use a twisted pair for the red (Data1) with ground (yellow of the black/yellow pair), and a twisted pair for blue (Data0) with ground (yellow 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 singlepoint earth ground on the controller end of the cable.

Figure 3-2 eGo Plus Security Sticker Tag eGo Plus License Plate Tag The eGo Plus LPT (Figure 3-3) is a water-resistant tag used in applications requiring an exterior-mounted tag.
Encompass 4H Reader System Guide Figure 3-3 eGo Plus License Plate Tag TransCore’s eGo Tags TransCore’s various eGo tags are offered to complete your Encompass 4H Reader System. Table 3-3 lists some of the features of the TransCore eGo tags.
Choosing, Installing, and Removing Tags Figure 3-4 eGo Windshield Sticker Tag eGo License Plate Tag The eGo LPT (Figure 3-5) is a water-resistant tag used in applications requiring an exterior-mounted tag. Figure 3-5 eGo License Plate Tag Installing eGo Plus Sticker Tags eGo Plus 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.
Encompass 4H Reader System Guide 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 4H Reader-compatible LPT on the vehicle. See the section “Installing eGo Plus License Plate Tags” on page 3-13. Contact TransCore for more information.
Choosing, Installing, and Removing Tags Figure 3-7 eGo Plus Sticker Tag Placement Large Truck with No Inside Mirror Choose this option for a large truck that uses exterior mirrors only (Figure 3-8). Figure 3-8 eGo Plus Sticker Tag Placement in Large Truck eGo Plus Sticker Tag Installation Procedures Caution Confirm that the outside temperature is above 50°F (10°C). The sticker tag may not adhere correctly if the temperature is below this temperature. To install the eGo Plus Sticker Tag 1.
Encompass 4H Reader System Guide 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 (Figure 3-9), 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.
Choosing, Installing, and Removing Tags Installing eGo Plus Security Sticker Tags An eGo Plus Security Sticker Tag is located in the same area on the windshield as the eGo Plus Sticker Tags. See “Positioning eGo Plus Sticker Tags” on page 3-8 for this information. The eGo Plus Security Sticker Tag is slightly less flexible than the eGo Plus Sticker Tag so the installation instructions differ.
Encompass 4H Reader System Guide Figure 3-11 Applying eGo Plus Security Sticker Tag to Windshield 6. Press the security sticker tag firmly against the glass. Gently rub over the entire tag surface removing as much air from underneath the tag (Figure 3-12). The security sticker tag’s rigid case may prevent you from forcing out all of the air trapped between the tag and windshield. A minimal amount of air will not affect tag performance.
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 LPTs 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.
Encompass 4H Reader System Guide Figure 3-13 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 3-13. 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. 3.
Choosing, Installing, and Removing Tags Figure 3-15 Upper Placement Over the Top Area of the License Plate Installing eGo Windshield Sticker Tags eGo WSTs 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.

General Software Information Chapter 5 General Software Information This chapter provides software-related information for the Encompass® 4H Reader System. This chapter presents various software-related topics arranged in alphabetical order by subject. In addition to this chapter, refer to Chapter 6, “Communications Protocols,” and Chapter 7, “Commands for more information. Command Entry Conventions All Encompass 4H Reader commands are preceded by the start-of-message character (#).
Encompass 4H Reader System Guide Table 5-1 Four-Character Command Structure (continued) #1005 Set Baud Rate To 9600 Baud 5 Indicates the setting. Normally this is a variable and is usually a hexadecimal value from 0 through F. In this example, 5 sets the baud rate to 9600, the factory setting. In some commands, this digit may be a four-place hexadecimal string or a character string. Command Response Conventions Like the Encompass 4H Reader commands, responses are preceded by the # character.
General Software Information Operating Parameters The Encompass 4H 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 4H Reader System Guide Download Procedures If TransCore releases a new version of the Encompass 4H Reader software or if the Encompass 4H Reader seems not to be working properly, you may need to download the software to the Encompass 4H Reader. Contact technical support or your TransCore Encompass 4H Reader sales representative. Startup Upon startup, Encompass 4H Reader’s transmit a sign-on message or a boot ROM failure message.
General Software Information Tag/Message Buffer In basic communication protocol, the Encompass 4H Reader does not provide tag memory storage beyond the quantity required for uniqueness checking. This feature allows adequate buffering of tag data under normal operating conditions. The Encompass 4H Reader cannot operate as a stand-alone component. When the buffer fills, subsequent tag IDs will be lost.

6 Communications Protocols
Communications Protocols Chapter 6 Communications Protocols This chapter describes the communications protocols for the Encompass® 4 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.
Encompass 4H Reader System Guide 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.
Communications Protocols Error message, and the host computer will issue a negative acknowledgment message. 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 4H Reader acquires tags, it buffers them but does not transmit them. Instead, the host must poll the Encompass 4H Reader for each tag by sending a CTRL-E character (hex 5 digit).
Encompass 4H Reader System Guide An ASCII string up to 72 characters long. This string may contain tag data, a presence without tag report; an input status change report; an Error06, Error07, Error08, or Error11 message; or a sign-on message. Auxiliary data may also be included. Field containing four ASCII digits that represent the 16-bit CRC value calculated on the message. The CRC value is calculated on bytes between the som character and the first byte.
Communications Protocols The host computer resets the anticipated data message sequence number to that of the Encompass 4H Reader before communications can resume without error.
Encompass 4H Reader System Guide Host Transmission The host computer initiates synchronous communications between the Encompass 4H Reader and the host. The host begins a sequence by issuing a command; the Encompass 4H Reader responds accordingly. The data inquiry protocol format is as follows: The basic protocol format is as follows: [] The ECP format is as follows: [] where ASCII Control E (hex 5 digit).
Communications Protocols CRC value for the message End-of-message character (ASCII CR) Reader Command Response The basic protocol format is The ECP format is where Start-of-message (ASCII # character) Echo of sequence number received in host command message Response string. The Encompass 4H Reader returns Done, Error, or another ASCII string depending on the host transmission. This string can be up to 72 characters long.

Communications Protocols Command has been invoked by the Encompass 4H Reader Done Reader response #7Done or #7Error For some commands, the Encompass 4H 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.
Encompass 4H Reader System Guide where errckh (ms) Processing period to perform error checking by receiver The host computer can remotely set the Encompass 4H Reader’s communications parameters while in the command mode, but TransCore does not recommend this action if communications conditions are marginal. After the Encompass 4H Reader receives new communications parameters, the Encompass 4H Reader issues the Done message and switches to the new configuration immediately.
Communications Protocols Incorrect CRC If the Encompass 4H Reader detects an incorrect CRC value in a host command message, it discards the received message. No response is sent. If it receives an incorrect CRC value in an ACK message, it responds as if a NAK had been received, and it retransmits the data. Illegal Command If the Encompass 4H Reader receives an illegal command, it returns its standard Error message.
Encompass 4H Reader System Guide Receive Timeout If the host receives a but does not receive a matching within a specified timeout interval, it discards the incomplete message and resets its receiver. Asynchronous Message/Command Message Collision If the host receives an asynchronous reader transmission at the same time it transmits a command, it ignores the asynchronous message and waits for the Encompass 4H Reader’s response.
Communications Protocols on the trade-off between code memory and processing overhead. Example 1 presents an example of a function (CALCCRC) that calculates the CRC value through a call to a separate function (UPDCRC). unsigned short calccrc(char *message) { unsigned short crc = 0; for ( ; *message != (char)0;message++) crc = updcrc(*message & 0xff, crc); return (crc) } Example 2 shows an example of UPDCRC that does not require a lookup table.

7 Commands
Commands 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.
Encompass 4H Reader System Guide Note: The Encompass 4H Reader transmits ID codes 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.
Commands While in download mode, the Encompass 4H Reader turns RF off, does not process tags, and does not echo host commands. 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 Appendix D 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.
Encompass 4H Reader System Guide Communications Port Control — Command Group 1 Group 1 commands configure the parameters used by the Encompass 4H 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 Command #100N selects the reader baud rate. The factory-default setting is 9600 baud. The N variable specifies the baud rate shown in Table 7-1.
Commands Reader response: Done 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 7-3.
Encompass 4H Reader System Guide 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.
Commands 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.
Encompass 4H Reader System Guide 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).
Commands ID Filtering — Command Group 4 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 Command #40 instructs the reader to transmit all IDs without regard for uniqueness. This command can be useful when tuning the lane and mapping the footprint or performing diagnostics.
Encompass 4H Reader System Guide 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. Note: A new ID can fail the filter test and not be transmitted; however, it remains stored in the comparison register. The uniqueness test’s time limit is set by Command #441.
Commands Command Timeout Clock #441 #442 #443 2 minutes (factory setting) 15 seconds 30 seconds Entering these commands effectively expires the timeout clock, which erases all current IDs in the comparison register. In effect, the first ID that is acquired after the clock expires always appears to be new and is stored. Newly acquired IDs are only tested against IDs that are registered after the clock resets.
Encompass 4H Reader System Guide 453 Enable Tag Translation Mode Command #453 enables the translation of tags in AAR and ATA formats. Specific data fields, such as owner ID and car number, will be extracted from these tags, translated according to AAR or ATA standards, and converted to ASCII. Tags that are not programmed in AAR or ATA format will be directly converted to ASCII. The reader will not attempt to translate data from half-frame or dual-frame tags.
Commands 458 Disable Second Alternate Group Select (Factory Default) Command #458 is a default set in the factory to disable the second alternate group select function. Reader response: Done 459 Enable Second Alternate Group Select Command #459 enables the second alternate group select function that allows the reader to distinguish tags meeting specific criteria pre-programmed into the tags.

Encompass 4H Reader System Guide Command #582 displays the synchronization values, which are typically used to alleviate interference issues in dense populations of Interagency Group (IAG) readers. The values are set with commands #648NN and #649NN.
Commands The transmit timeout is initiated immediately after the end-of-message sequence CR/ LF is transmitted. If the host does not acknowledge the message within the specified interval, the reader times out and retransmits the message. The receive timeout is initiated upon receipt of the start-of-message character (#). If the end-of-message character (CR) is not received within the specified interval, the reader discards the partially received message and resets its receiver.
Encompass 4H Reader System Guide Reader response: Done If the reader is configured for software flow control (XON/XOFF), it stops transmitting if it receives an XOFF character (host software command 13H). It does not resume transmitting until it receives an XON character (host software command 11H). If the reader is configured for hardware flow control (RTS/CTS, request to send/clear to send), it stops transmission if it detects that the CTS line is no longer asserted.
