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. Caution Attempting to read an Intellitag-based tag in the presence of an ATA or ISO read-only tag may provide unreliable results.
Developing the Site Plan Polarization The polarization of the tag must be aligned in the same direction as the Encompass 4 Reader, as shown in Figure 2-1. Note: Matching the tag and antenna polarization is critical to obtain optimal system performance.
Encompass 4 Reader System Guide Unobstructed Line of Sight For optimum readability, install the Encompass 4 Reader and the vehicle’s tag so that when the vehicle approaches the Encompass 4 Reader, the tag is directly facing the reader and the line of sight is clear between the Encompass 4 Reader and the tag. If a fence or barrier is between the tag and the reader, the Encompass 4 Reader cannot reliably read the tags.
Developing the Site Plan 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 2-3. Figure 2-3 Typical Tag Positions for U.S. Driver’s Side Reader 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 2-4. Figure 2-4 Typical Tag Positions for U.S.
Encompass 4 Reader System Guide If the Encompass 4 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 Reader and may cause tags to be misread.

Encompass 4 Reader System Guide Unobstructed Line of Sight For optimum readability, install the Encompass 4 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.
Developing the Site Plan • 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 2-6 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.
Developing the Site Plan Parking Garage with Ticket Island Configuration Figure 2-7 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 2-8 Overhead Installation Lane Configurations for Encompass 4 Readers 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.
Developing the Site Plan as shielding, absorbing, range sensitivity adjustment, or barriers can also be used. See Chapter 9, ”Troubleshooting and Maintenance” for more information. 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.

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 4 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 4 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 4 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 4 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.

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.
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 a CTRL-E character (hex 5 digit).
Encompass 4 Reader System Guide 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. When the host receives a properly framed message, it can calculate a 16-bit CRC value.
Communications Protocols The host computer resets the anticipated data message sequence number to that of the Encompass 4 Reader before communications can resume without error.
Encompass 4 Reader System Guide Host Transmission The host computer initiates synchronous communications between the Encompass 4 Reader and the host. The host begins a sequence by issuing a command; the Encompass 4 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 End-of-message character (ASCII CR) Reader Command Response The basic protocol format is The ECP format is 6-9
Encompass 4 Reader System Guide where Start-of-message (ASCII # character) Echo of sequence number received in host command message Response string. The Encompass 4 Reader returns Done, Error, or another ASCII string depending on the host transmission. This string can be up to 72 characters long.
Communications Protocols # Start-of-message character 4 Message sequence number @ ACK (acknowledgment character) (? returned for a negative acknowledgment) CRC value for the message End-of-message character Host Command Transmissions Basic protocol host transmission #647XXX Reader response #Done or #Error #Error is returned if the host transmission is not a legal command with legal data.
Encompass 4 Reader System Guide #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. The Encompass 4 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.
Communications Protocols pass 4 Reader issues the Done message and switches to the new configuration immediately. The host computer switches its communications parameters immediately after the transaction is complete. As noted, the message initiator, such as the Encompass 4 Reader in data mode and the host computer in command mode, starts a timeout counter at the time a message is transmitted.
Encompass 4 Reader System Guide If the Encompass 4 Reader receives an illegal command, it returns its standard Error message.
Communications Protocols Transmission Timeout If the Encompass 4 Reader transmits an asynchronous message and the host does not send an ACK before the ECP timeout occurs, the Encompass 4 Reader retransmits the message. 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.
Encompass 4 Reader System Guide ECP Reliability An undetected error is defined as a message having incorrect data or status but no parity or CRC errors. An error transaction is defined as a message having either a parity or CRC error. Laboratory testing indicates an undetected error rate of less than one undetected error per 1,000,000 error transactions with parity enabled.

Commands 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.
Encompass 4 Reader System Guide 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.
Commands 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 4 Reader System Guide Group 1 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 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 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. Table 7-3 Select Parity Commands Command Data Bits Parity Selected 1020 8 Disable parity (factory default) 1021 7 Select even parity 1022 7 Select odd parity Reader response: Done Command Group 2 Group 2 commands control the real-time clock which maintains the Encompass 4 internal time and date.
Encompass 4 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 4 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 4 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 4 Reader System Guide 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. If an ID is buffered, it will not be accepted again unless it arrives at the reader more than the programmed time interval from the previous arrival or until the receipt of one or more other IDs reset the uniqueness.
Commands #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. The timeout clock is continually reset (does not expire) as long as the reader receives the same tag ID.
Encompass 4 Reader System Guide 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 4 Reader System Guide 46NN Set Wiegand Retransmit Interval Command #46NN sets the time delay to control the reader retransmission of Wiegand data of a tag remaining in the read zone where NN is a hexadecimal code from 01 to FF. Note: The actual value of the Wiegand retransmit interval may vary depending on the operative tag read mode and the type of tag in the read field. For example, 10 = 16 seconds and FF = 255 seconds. The factory default is 4601 (1 second).
Commands Command #488 disables the reader from reading factory-programmed eATA data from tags. 489 Enable eATA Command #489 enables the reader to read factory-programmed eATA data from eGo Plus or eGo tags.
