Introduction1-51Figure 1-1 SmartPass Front and Side ViewsSmartPass generates an RF signal that is reflected by an Amtech radio frequency identification (RFID) tag installed on a vehicle. The tag adds its programmed identification information to the signal and reflects the signal back to SmartPass. SmartPass receives and decodes the tag data carried by the reflected signal and transmits this data to a local host computer for processing.License RequirementsSmartPass system users in the U.S. must obtain a license from the Federal Communications Commission (FCC). The authorized frequency band in the U.S. is 902 to 904 and 909.75 to 921.75 MHz.The user is responsible for filing the FCC license according to FCC regulations, but the Amtech dealer should provide assistance and support as necessary to complete these forms. Forms and information for obtaining the license are located in the SmartPass Dealer Binder.An FCC license provides the user with the legal authorization to operate SmartPass on the licensed frequencies at the site specified in the license. Only an authorized installer or service technician can set the SmartPass AI1620 series of readers’ frequency to that specified in the FCC site license. No end-user-operated controls exist on these SmartPass models.The FCC license also provides the user with protection and authorization to maintain the system should any other RFID product be used in the licensed area after your SmartPass equipment is installed.

Developing the Site Plan2-32This chapter discusses how to develop a site plan for installation of SmartPass.OverviewDeveloping a site plan provides the foundation for the site’s system design and establishes system configuration parameters such as the following:•Number and general location of primary components•Number of different RF frequencies requiredThis information is crucial before applying for FCC approval and ordering and installing SmartPass(es) and tags. Also consider the following factors when developing this site plan:•Reader and tag alignment•Site layout and traffic flow•SmartPass electrical requirements•SmartPass communications requirementsThese factors provide relevant information regarding each site’s physical and electromagnetic environment and the conditions under which the system must perform.Reader and Tag AlignmentThe position of SmartPass and placement of the tag on the vehicle must be compatible. It is important to consider any existing tagged vehicles currently using the facility because you will need this information to determine the optimal SmartPass location at the site.Note: If any of the vehicles using your facility already have tags, such as those used in toll applications, contact Amtech at 1-800-923-4824 for information about mixed-tag installations before you plan tag type, location, and programming.Three primary criteria must be satisfied to achieve the highest read reliability:•Polarization of the tag and SmartPass must be aligned in the same direction (both horizontal or both vertical).•The installed tag must be in a direct, unobstructed line of sight to SmartPass.

AI1620 SmartPass System Guide2-4•Tags designed to be mounted in a vehicle windshield must be mounted in the vehi-cle’s windshield, and tags designed to be mounted on the metal surface of the vehicle must be mounted on the metal surface of the vehicle’s exterior. Tag read may not be reliable unless these criteria are met.PolarizationJust as antennas are, tags are polarized (Figure 2-1).Note: Matching the tag and antenna polarization is critical to obtain optimal system performanceFigure 2-1 Tag Horizontal and Vertical OrientationThe polarization of the tag must be aligned in the same direction as the SmartPass reader, as shown in Figure 2-1. A horizontally oriented SmartPass cannot read a vertically oriented tag and vice versa. SmartPass polarization is set at the factory and vertical polarization of the reader, if required, must be a requested option on the purchase/sales order.

Developing the Site Plan2-52Unobstructed Line of SightFor optimum readability, install SmartPass and the tag on the vehicle so that when the vehicle approaches SmartPass, the tag is directly facing the reader and the line of sight is clear between SmartPass and the tag. For example, if tags have been installed in vehicles to be read by SmartPass located on the driver’s side curb, SmartPass mounted on the opposite curb cannot read the tags reliably. Likewise, if a fence or barrier is between the tag and SmartPass, SmartPass cannot reliably read the tags. Figure 2-2 illustrates correct and incorrect installation of a SmartPass in relation to a tag’s mounting location on a vehicle.Figure 2-2 SmartPass Location Relative to Tag Position

AI1620 SmartPass System Guide2-6If SmartPass is installed on the curb or wall on the driver’s side (U.S.), tags should be installed on the driver’s side of the vehicle as illustrated in Figure 2-3.Figure 2-3 Typical Tag Positions for U.S. Driver’s Side ReaderIf SmartPass is installed on the passenger’s side curb (U.S.), tags should be installed on the passenger’s side of the vehicle as illustrated in Figure 2-4.Figure 2-4 Typical Tag Positions for U.S. Passenger’s Side Reader

$Developing the Site Plan2-72If SmartPass is installed in an overhead location, tags should be installed in the center windshield in the top center area behind the rear view mirror or on the vehicle’s front license plate or center bumper as illustrated in Figure 2-5.Figure 2-5 Typical Tag Positions for SmartPass Mounted OverheadNote: Metallized coatings on some vehicle windshields and windows shield the radio frequency energy emitted by SmartPass, and may cause tags to be misread. Always install tags on the exterior of vehicles having this type of window coating.Refer to Chapter 3 for more detailed information on tag positioning.Site Layout and Traffic FlowSite layout and traffic flow considerations are critical when determining SmartPass installation locations. These factors include the following:•SmartPass read zone•Other SmartPasses in the area•Lane configurations•Reflection, refraction, and diffraction of RF signals •Existing signal interference at the site$

AI1620 SmartPass System Guide2-8SmartPass Read ZoneSmartPass 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 SmartPasses at the site. The following are some of the factors that affect the size and shape of the read zone:•Mounting method used (pole or wall mount)•Height from the ground•Indoor or outdoor location•Range discrimination setting•Other sources of interference and reflection SmartPass 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. For instructions on setting the read zone, see “Marking the Read Zone” on page 8-14.Other SmartPasses in the AreaSites with more than one SmartPass in close proximity should be configured with a frequency separation of at least 6 MHz. If more than one SmartPass is in a side-by-side or multiple lane application, the frequencies should be staggered. Also, two SmartPasses will not operate accurately if they directly face each other. Lane ConfigurationsAmtech recommends that traffic be guided through a controlled lane to obtain consistent accurate tag readings and to prevent damage to SmartPass. The following subsections describe some common lane configurations and give suggestions for positioning SmartPass within the controlled traffic flow.Open Lane ConfigurationAn open lane configuration is one in which no center barrier separates two opposing traffic flows. Figure 2-6 illustrates a sample open lane configuration and SmartPass placement. This figure assumes that tags are mounted on the inside windshield on the passenger side (U.S.) of the vehicle.

Developing the Site Plan2-92 Figure 2-6 Open Lane Configuration

AI1620 SmartPass System Guide2-10Another option for SmartPass placement in an open lane configuration is one in which SmartPass is mounted overhead in each lane as illustrated in Figure 2-7. This figure assumes that tags are mounted on the inside center windshield or center bumper of the vehicle. Figure 2-7 Overhead Open Lane Configuration

Developing the Site Plan2-112Gate with Center Island ConfigurationFigure 2-8 illustrates a typical gate application with SmartPass units positioned on a center island to read tags mounted on the inside windshield on the driver’s side (U.S.). The readers are placed to allow time for the gate to open so that the vehicle can roll through without stopping.Figure 2-8 Gate Application with Center IslandParking Garage with Ticket Island ConfigurationFigure 2-9 illustrates a parking garage application with each SmartPass mounted on the ticket island to read tags mounted on the inside windshield on the driver’s side (U.S.) or on the front vehicle bumper. SmartPass is placed to require the vehicle to stop before the gate opens.

$AI1620 SmartPass System Guide2-12Figure 2-9 Parking Garage ApplicationReflection, Refraction, and Diffraction of RF SignalsRF signals can be reflected, refracted, or diffracted by metal objects, walls, and even wet pavement or ice. Any of these effects can alter or degrade system performance. When designing your site plan, you must consider permanent structures and transient factors in the vicinity that may affect RF signals being generated by SmartPass. Permanent structures include buildings, chain link fences, guard shacks, and gates. Transient factors include passing traffic and local weather conditions such as rain or snow. Symptoms of these effects would include reading tags that are out of the desired read zone, or cross-lane reads.The most common RF reflectors are metallic surfaces. RF signals may be partially reflected by nonconducting materials such as dirt, wood, ice, asphalt, and concrete. When nonconducting materials in the system environment become wet, they increase reflection of RF signals.SmartPass mounting location, aiming, range control adjustment, discussed in Chapter 8, and use of presence detectors can reduce interference from RF reflections. When these actions cannot adequately control reflections, other techniques such as shielding, absorbing, range sensitivity adjustment, or barriers can also be used. See Chapter 9.$

Developing the Site Plan2-132Existing InterferenceInterference 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.Existing interference at the site may be shielded, removed, or positioned further from the SmartPass. In some cases, changing the operating frequency of the SmartPass may provide a simple solution. See Chapter 9.Electrical and Communications RequirementsAll construction work at the site must be completed before installing SmartPass. Electrical and communications cables should be installed according to all applicable local and federal building code requirements. Specific instructions to position and install SmartPass are in Chapter 8.Junction BoxA watertight junction box meeting applicable local and national building codes is recommended for connecting SmartPass power and communications wiring. Amtech recommends a NEMA Type-4 junction box with a back panel. The junction box will house the terminal strip for communications and power connections. Power and Communications CableThe appropriate cable length for power and communications depends on the physical characteristics of SmartPass installation site. Table 2-1 lists accessory kits available for cabling options based on your site’s requirements.Table 2-1 Connector Cabling Accessory KitsPart Number Description58-1620-001 5-ft connector cable58-1620-002 20-ft connector cable20-1620-003 Connector kit only56-1620-004 13-Pair cable (1-ft lengths)76-1620-005 110 V AC to 18 V AC Class C transformer76-1620-006 12 V AC to 18 V AC step-up transformer

AI1620 SmartPass System Guide2-14Electrical Power A dedicated electrical power supply must be present at the site and be available to SmartPass at all times. The power must be 16–28 V DC or 16–20 V AC. A step-down transformer is available (North America only) to convert a 120 V AC duplex wall out-let with ground to 18 V AC, or a step-up transformer to convert a low-voltage 12 V AC outlet to 18 V AC. Consult your local and national electrical codes for installation and safety requirements.Note: SmartPasses installed outside North America will require a locally supplied transformer. If 18 V DC or 18 V AC power is available, the transformer option will not be necessary.Amtech offers a Class C transformer accessory kit (part number 76-1620-005) for sites where 110 V AC is available. It is the installer’s responsibility to supply conversion equipment and wiring for other voltages. Table 2-2 contains power supply current requirements.Power circuits are protected internally against power surges. Power ExtensionMeasured voltage at SmartPass must be at least 16 V for proper operation. Use Table 2-3 to determine the correct cable size for the necessary cable length. The table is an approximation.Table 2-2 Power Supply Current RequirementsSupply Worst Case Maximum Current at 68°F (20°C)Standby Operating Current at 68°F (20°C)16 to 20 V AC 800 mA at 18 V AC 400 mA at 18 V AC16 to 28 V DC 800 mA at 18 V DC 400 mA at 18 V DC

Developing the Site Plan2-152Note: If close to the maximum length, measure voltage at SmartPass to ensure it does not drop below 16 V. Host CommunicationsYour site design must include communications between SmartPass and a host com-puter. SmartPass communicates with the host computer through an asynchronous serial line or through a Wiegand interface. This serial line can be an RS–232 interface or an RS–422 interface. The host computer must be able to accept one of the interfaces shown in Table 2-4.Communications circuits are protected internally against power surges. Select one of the following communications interfaces based on the specific needs of your site.Table 2-3 Cable length from Amtech-Supplied 110 V AC to 18 V AC Transformer to AI1620 SmartPassCable Size (AWG)a24 22 20 18 16 14 12Maximum DCR (Ohms per foot at 68° F)b0.0270 0.0175 0.0109 0.0069 0.0044 0.0027 0.0017Maximum length (feet) 29.63 45.71 73.39 115.61 183.91 293.04 467.84Maximum length (feet)c25 39 62 98 156 249 398When used to extend Amtech 5-ft cable (feet) 23 36 57 90 143 227 363When used to extend Amtech 20-ft cable (feet)14 22 35 55 88 140 224a.

AI1620 SmartPass System Guide2-16RS–232 InterfaceUse an RS–232 interface if one or more of the following items apply to your site:•The host computer system is 50 ft (15.2 m) or less from SmartPass.•The host computer system is more than 50 ft (15.2 m) from SmartPass, and a pair of RF modems or limited distance modem/line drivers over copper wire are used for communications between SmartPass and the host. The distance from the RF modem to SmartPass should not exceed 50 ft (15.2 m).•Other common communications devices that use RS–232 have been selected, such as fiber optics.RS–422 InterfaceUse an RS–422 interface if one or more of the following items apply to your site:•The host computer is more than 50 ft (15.2 m) from SmartPass.•The host computer has an external limited-distance modem. The standard RS–422 connection maximum distance depends on the baud rate, cable type, and the RS–422 device at the other end. Wiegand InterfaceSmartPass can interface with equipment requiring the Wiegand +5VDC data0-data1-ground interface. It does so using the Wiegand interface included with the RS–232 or RS–422 option.Note: SmartPass comes from the factory with both the RS–232 or RS–422 option AND Wiegand. If you wish to use Wiegand, you must first connect SmartPass using the RS–232 or RS–422 interface, set SmartPass’s configuration to Wie-gand, and then connect SmartPass using the Wiegand interface.Note: You must order tags programmed with Wiegand-formatted data when using a Wiegand-compatible reader.Input/Output CircuitsTo connect SmartPass to external equipment such as a treadle or traffic control light, install wires from these devices at the junction box. SmartPass input circuit is designed to connect to a dry contact closure. SmartPass output circuits are single-pole, double-throw relays providing dry contact closures. These contacts are rated at 42.2 V AC peak, or 60 V DC, at 1 A maximum.Output circuits are not intended for the direct control of electromechanical devices such as motorized gates and barrier arms. For such applications, the SmartPass output circuits should be used to drive a secondary, appropriately rated high-power relay.

3Choosing, Installing, and Removing Tags

Choosing, Installing, and Removing Tags3-33This chapter describes the various tag types compatible with the AI1620 SmartPass and gives procedures for installing and removing internal and external tags. Tag TypesAmtech offers numerous tag models and four tag data formats to complete your SmartPass system. The information in the next subsection will assist you in determining the correct tag model and tag data format for your system.Tag ModelsAccess control tags are laser-etched with the tag model number and date of manufacture and factory-programmed tag data. Table 3-1 lists most tag models that can be used in parking and access control applications. Use this table as a guide to help determine which type(s) of tags will be best suited for your specific site’s requirements.Table 3-1 Tag Configuration GuidelinesTag Model Number TagType Power SourceNumber of 6-Bit ASCIICharactersNumber of 128-Bit FramesNumber of Wiegand Bits Special FeaturesAT5100 Toll Beam 20 1 N/A 915 MHz, thin case, non-metal window installAT5102 Access control Beam 10 1/2 25 to 54 915 MHz, thin case, non-metal window installAT5105 Access control 5-yr battery 10 1/2 25 to 54 Multifrequency, thin case, non-metal window installAT5106 Access control 10-yr battery 10 1/2 25 to 54 Multifrequency, sealed case, non-metal window install or non-metal external installAT5107 Access control 10-yr battery 10 1/2 25 to 54 Multifrequency, sealed case, metal external install

AI1620 SmartPass System Guide3-6Tag Data Formats Tags are programmed at the Amtech factory with the tag model number, date of manufacture, and data format. Consult the special order entry procedures in your SmartPass Dealer’s Guide for ordering the format that applies to your system. The following four tag data formats can be used: •10-character alphanumeric ASCII — Four alphanumeric characters are fixed and can be used to identify either the dealer or the user. The remaining six positions are numeric and should be unique for each tag issued. For example, the entry ACME000001 might be specified as the first tag on the SmartPass order entry form from ACME Parking Garage.•20-character alphanumeric ASCII — Four alphanumeric characters are typically fixed and the remaining sixteen positions are numbered sequentially.•Wiegand — Tags can be programmed in Wiegand formats with 25 to 54 bits. If you choose this format, complete a Wiegand format worksheet — attached to the SmartPass order entry form — indicating the data to be programmed into the tags.Note: Only access control tag models can be Wiegand-formatted. See Table 3-1 on page 3-3 for Wiegand-compatible tag models.•AAR/ISO — For requirements for this format, refer to ISO 10374 and the most recent version of Association of American Railroads Standard for Automatic Equipment Identification.Installing Interior TagsInterior tags are used in those applications requiring tags that can be moved from one vehicle to another. Interior tags are installed using hook-and-loop material or double-sided tape attached to the tag and to the windshield. When using hook-and-loop material, the loop material should be applied to the back of the tag and the hook material should be applied to the windshield. After the tag is installed, it can be easily AI1620-104 AT5100; AT5102; AT5110; AT5112; AT5125; AT5145; AT5146; AT5715 AT5105; AT5114; AT5140; AT5147; AT5510; AT5540; AT5541; AT5542; AT5543; AT5544; AT5545; AT5547; AT5704; AT5707AI1620-105 AT5100; AT5102; AT5110; AT5112; AT5125; AT5145; AT5146; AT5715 AT5105; AT5114; AT5140; AT5147; AT5510; AT5540; AT5541; AT5542; AT5543; AT5544; AT5545; AT5547; AT5704; AT5707Table 3-2 Reader/Tag InteroperabilityReader Beam Tags Battery Tags

Choosing, Installing, and Removing Tags3-73removed and used in any vehicle that has corresponding hook material affixed to the windshield.Note: Installing interior tags using double-sided tape results in a semipermanent attachment; then the tag will be more difficult to remove than one installed using hook and loop material.Interior tags may be ordered from the factory with hook-and-loop material or double-sided tape already applied to the tag. The adhesive on this material is specially formulated for temperature extremes inside vehicles.Materials RequiredYou will need the following materials to install interior tags:•Rubbing alcohol or 50/50 isopropyl alcohol and water•Sponge and dry cloth•Interior tags with two strips of factory-installed hook-and-loop material attached or factory-installed double-sided tapeTag PositioningInterior tags can be installed on the driver’s side, passenger’s side, or upper center of the vehicle’s windshield, depending on SmartPass’s position. See “Reader and Tag Alignment” on page 2-3.Tags should be mounted consistently in all vehicles using a particular SmartPass facility. Interior Driver’s or Passenger’s SideInterior tags are designed to be installed inside the vehicle, typically on the driver’s side of the windshield. Install the tag in either the upper or lower corner, as long as it is at least 2 in. (5 cm) from the metal window post, as shown in Figure 3-1.

AI1620 SmartPass System Guide3-8.Figure 3-1 Driver’s or Passenger’s Side (U.S.) Interior Windshield Tag LocationInterior Center WindshieldAccess control tags may also be installed on the upper center portion of the wind-shield. Position the tag as close as possible to the windshield’s upper center, behind the rearview mirror. The top edge of the tag should be approximately 1 in. (2.5 cm) below the base of the mirror, or above the base if enough room is available for the tag to be 2 in. from the metal around the windshield, as shown in Figure 3-2.Figure 3-2 Upper Center Interior Windshield Tag LocationInstallation ProceduresPerform the steps below to install interior tags:1. Clean the tag installation area on the interior surface of the windshield with rubbing alcohol.2. Dry the area thoroughly using a clean, dry cloth.

Choosing, Installing, and Removing Tags3-933. Remove the clear backing from the two strips of hook-and-loop material on the back of the tag (Figure 3-3) or from the double-sided tape.Figure 3-3 Hook-and-Loop Material on Interior Tag4. Position the tag over the correct area of the windshield, making sure that the tag and SmartPass orientation are the same (horizontal or vertical).5. Press the tag firmly against the glass.Removing Interior TagsTo remove an interior tag installed using hook-and-loop material, simply pull the tag away from the windshield.To remove an interior tag installed using double-sided tape, slowly pry off the tag with a thin tool, such as a putty knife.Installing Exterior TagsExterior tags are used in applications that require tags to remain affixed to one vehicle using semipermanent installation methods, and for vehicles with metallized coatings on their windshields and windows.Metallized coatings on some vehicle windshields and windows absorb the RF energy emitted by SmartPass, thus causing tags to be misread. Use either license plate or bumper installation techniques to install tags on the exterior of vehicles that have this type of window coating.Note: The read zone of an overhead SmartPass should be adjusted accordingly when an exterior tag is installed on a license plate, or the read zone will be reduced.

AI1620 SmartPass System Guide3-10Exterior tags may be installed on metal or plastic bumpers depending on the tag model, using pop rivets or screws. Materials RequiredExterior tags need to be installed on a relatively flat surface. You will need the following materials to install exterior tags:•Rubbing alcohol, or 50/50 isopropyl alcohol and water, or solvent/cleaner for metal•Sponge and dry cloth•Exterior tags with the double-sided adhesive tape attached or exterior tags and blind rivets if using blind rivet installationTag PositioningSome access control tags, such as model AT5114, are designed to be installed on a truck bumper, as shown in Figure 3-4. Other access control tags, such as models AT5146 and AT5147, are designed to be installed on the vehicle’s license plate, also shown in Figure 3-4.Figure 3-4 Ideal Exterior Tag Locations

If it is, the problem is probably in the communications between SmartPass and the host.

AI1620 SmartPass System Guide4-20Configuring SmartPass ParametersFollow the procedures in this section to configure SmartPass parameters using SmartPass Host v2.01. Procedures are listed in alphabetical order by parameter. The PC must be connected to and communicating with SmartPass, and SmartPass Host must be started, as described in the section “Verifying PC-to-SmartPass Communications” on page 4-15. Note: If you are using Wiegand mode, you must connect the PC or laptop to Smart-Pass using the RS-232 or RS-422 interface before attempting to send commands to the reader. You can leave the Wiegand interface connected during this procedure. Appended Tag DataUse this procedure to set appended tag data parameters using SmartPass Host. See the section “30N Append Time and Date Selection” on page 7-10 and the section “31N Append Auxiliary Information Selection” on page 7-10 for more information. 1. Select the Tag & RF drop-down menu and click on Appended Data. Figure 4-9 illustrates the options for appending information to tag data. Figure 4-9 Select Appended Data Dialog Box2. Click the option you want to select; then click OK to make the change.Check TagSmartPass supports both host-invoked and periodic check tag operations. If a real tag is in the field when a check tag operation begins, the check tag operation will be aborted. The check tag operation involves use of internal check tag circuitry (internal check tag option). The circuit of an Amtech check tag is built into each reader to allow a host computer to remotely diagnose SmartPass. The host sends SmartPass command 8110 to activate the check tag. SmartPass transmits the RF signal, which is reflected back into the

Testing and Configuring SmartPass Before Installation4-214receive circuits by the check tag, just as if a normal tag had been placed into the read zone. The check tag contains the data SYSTEM CHECK TAG that SmartPass will receive, decode, and send to the host system.Use the following procedure to set check tag options using SmartPass Host. See the section “810 Disable Periodic Check Tag (Factory Default)” on page 7-41 for more information. 1. Select the Tag & RF drop-down menu and click Checktag Options. Figure 4-10 illustrates the submenu for check tag operations. Figure 4-10 Check Tag Options SubmenuNote: Only the internal check tag is available on the AI1620 SmartPass. Selecting the external check tag option will return an error message.

AI1620 SmartPass System Guide4-222. To disable or enable periodic check tag, click Periodic Checktag option to display the Select Periodic Checktag Option dialog box, as shown in Figure 4-11.Figure 4-11 Select Periodic Checktag Option Dialog Box3. Click the option you want to select; then click OK to make the change.ID SeparationThe host can select a unique ID separation of one ID (command 4100) or two IDs (command 4101). The uniqueness timeout is fixed at 2minutes. The reader default operation is for a unique ID separation of one ID and a uniqueness timeout of 2minutes. The host computer can disable the uniqueness check using command 40 (transmit all IDs) or command 43 (buffer all IDs). In this case, every tag ID received will be transmitted without regard to uniqueness. The host can reinstate uniqueness checking with commands 4100 or 4101 (select ID separation).Use the following procedure to set ID separation using SmartPass Host. See the section “40 Transmit All ID Codes” on page 7-11 through the section “43 Buffer All ID Codes” on page 7-12.

Figure 4-12 Select Tag Filter Dialog Box2. Click the option you want to select; then click OK to make the change.Sense Output DevicesBoth the RS–232 and RS–422 configurations used by SmartPass have two sense output circuits — sense output0 and sense output1. By default, SmartPass operates in predefined output mode where sense output0 and sense output1 are asserted every time a unique valid tag is read. Both sense output devices are asserted by issuing command 621 (select the predefined sense output mode). They are not asserted when tags are acquired in the transmit all or buffer all ID mode, or when SmartPass is operating in Wiegand mode. The sense output pulse duration is variable (command 67N).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, 6201, 6202, or 6203. While under host control, the sense outputs are not automatically asserted when a valid tag is read. The host must issue command 621 to return to the predefined mode.ReportsSmartPass can be configured to transmit presence without tag reports and input status change reports. Both report messages are handled the same as incoming tag IDs and are buffered behind previously acquired tag IDs.A presence without tag report is transmitted in data mode only, and only if the system has a presence detector. This report is sent if a presence is detected without the detection of a valid tag ID.

AI1620 SmartPass System Guide4-24If configured with command 82N Select Input Status Change Report Option to transmit input status change reports, the reader will transmit a message to the host any time the inputs change state. Input status change reports are transmitted in data mode only. Input status change reporting is disabled by default.Use the following procedure to set presence reporting using SmartPass Host. See the section “82N Select Input Status Change Report Option” on page 7-42. Also refer to Chapter 6 for information on message formats.1.

To verify that the RF has been changed to the proper setting, select the Tag & RF drop-down menu and click the RF Frequency option to see the current frequency setting. RF TransmissionThe RF transmission can be controlled by any of the following methods:•A vehicle detector using one of the two sense input circuits •Software commands sent to SmartPass by the host •The sense input0 wire pair twisted together, as in the test configurationAs a factory default, SmartPass is configured to control the RF power with a vehicle detector. The vehicle detector can be a loop detector, an infrared sensor, or an ultrasonic detector that is connected to sense input0 to turn on the SmartPass RF transmitter.

AI1620 SmartPass System Guide4-30Figure 4-20 illustrates the three methods of controlling RF sense output.Figure 4-20 SmartPass RF Control OptionsVehicle Detector Controlling RF TransmissionFigure 4-20, Option A, shows a vehicle detector controlling the RF transmitter. This operation is preferred because then the RF transmits only when a vehicle is in the SmartPass read zone.

Testing and Configuring SmartPass Before Installation4-314Use the following procedure to set the option of the vehicle detector controlling SmartPass.1. Select the RF Control option from the Tag & RF pull-down menu. This displays the Select RF Control dialog box shown in Figure 4-21. Figure 4-21 Set Sensor Control of RF2. Click on 3 RF-By-Sensor; then click OK.Host Controlling RF TransmissionFigure 4-20, Option B, shows the host controlling the RF transmitter. Note: For information and instructions on executing software commands, refer to Chapter 8, “Commands.”If the vehicle detector is connected to the host computer, as shown in Figure 4-20, Option B, commands 6400 (RF transmitter off) and 6401(RF transmitter on) from the host control the SmartPass RF transmitter. Leave the setting on RF-By-Sensor. Continuous RF TransmissionTo test SmartPass, as described in the section “Testing Using an Audible Circuit Tester” on page 4-4, you can turn on the SmartPass RF transmitter continuously by twisting the red and green sense input0 wire pair together. SmartPass must be in command mode 6401, which enables the RF-by-input control (factory default). Sense InputsBoth the RS–232 and RS–422 configurations used by SmartPass 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. SmartPass sense inputs are designed to connect to a dry contact closure.

AI1620 SmartPass System Guide4-32You can configure SmartPass to generate input status change reports, which are transmitted like tag IDs. The host can then respond based on the true/false (closed/open) status of the sense inputs. See the section “Reports” on page 4-23.The following example shows how to set sense inputs using SmartPass Host. See the section “526 Display I/O Status” on page 7-18, the section “694N Select Input Inversion Option” on page 7-40, and the section “82N Select Input Status Change Report Option” on page 7-42.1.

This will display the Select Input Mode dialog box, as shown in Figure 4-23.Figure 4-23 Select Input Mode Dialog Box3. Click on Enable Input Inversion to switch the sense input status; then click OK.Serial Port CommunicationsSmartPass supports one communications port, which can be ordered as either RS–232/Wiegand or RS–422/Wiegand. For the RS–232 and RS–422 communications specifications, SmartPass maintains the following three sets of parameters that affect serial port communications:•Port configuration parameters (baud rate, data bits, stop bits, parity)•Communication protocols (basic, data inquiry, error correcting)•Flow control scheme (none, software, hardware) The default serial port configuration for each of these three parameters is as follows:•9600 baud, 8 data bits, 1 stop bit, no parity•Basic communications protocol•Software flow control (XON/XOFF)You can change these parameters in data mode and command mode operation by issuing commands with the host or through SmartPass Host. Use the following procedures to set serial port communications parameters using SmartPass Host.

AI1620 SmartPass System Guide4-34Port Configuration ParametersUse this procedure to set port configuration parameters using SmartPass Host. See the section “100N Select Baud Rate” on page 7-7 through the section “102N Select Parity” on page 7-8.1. Select the Communications drop-down menu and click the Parameters option. Figure 4-24 illustrates the options for port configuration parameters. Figure 4-24 Port Configuration Parameters Dialog Box2. Click the option you want; then click OK to make the change.Communications ProtocolUse the following procedures to set communications protocol.

Figure 4-26 Select Communications Protocol Dialog Box3. Click the option you want; then click OK to make the change. Software Flow ControlTwo modes of flow control are supported — software (XON/XOFF) and hardware (CTS - clear to send). The host can enable or disable flow control with command 614N.

AI1620 SmartPass System Guide4-36The host can use software control characters (XON/XOFF) or the hardware CTS handshake line to interrupt reader transmissions. When the reader is configured for software flow control, it stops transmitting if it receives the XOFF character from the host (command 13H). It resumes transmitting only when it receives the XON character (command 11H) from the host. Likewise, when the reader is configured for hardware flow control, it stops transmitting if it detects that the CTS line is no longer asserted. It resumes transmitting when this line is asserted. If flow control is not needed, the reader should be configured for no flow control (command 6140).Note: Amtech recommends that XON/XOFF flow control be disabled while using the error correcting protocol.Use the following procedure to set software flow control parameters using Smart-Pass Host. See the section “614N Select Flow Control Option” on page 7-27. 1. Select the Communications drop-down menu and click the Flow Control command. Figure 4-27 illustrates the two options for flow control. Figure 4-27 Port Configuration Parameters Submenu

General Software Information5-35This chapter provides software-related information for the AI1620 SmartPass system. The information covers version SP2-ACC V2.01 of the SmartPass software. This version will only execute on AI1620 SmartPass models. Note: Amtech strongly recommends that you read the READ.ME file on the Smart-Pass software diskette before you install or use SmartPass. This chapter contains various software-related topics arranged in alphabetical order by subject. In addition to this chapter, see Chapter 6 and Chapter 7.Command Entry ConventionsAll SmartPass commands are preceded by the start-of-message character (#). The end-of-message sequence expected from the host is a carriage return (CR). SmartPass terminates messages with a return and a line-feed (CR/LF). For example, the switch to command mode 01 is typed as follows:#01<enter>where:<enter> Enter or Return keySome command characters may be represented by the letter N. This letter indicates you are to supply a value. Maximum valid entries are the numbers 0–9 and the uppercase letters A–F. These letters allow for as many as 16 available user responses and is based on the hexadecimal numbering system. Commands have at least two characters following the # character. Table 5-1shows the basic structure of a four-character command.Table 5-1 Four-Character Command Structure#1005 (Set Baud Rate to 9600 Baud)#All commands are preceded by the # character.1The entry in the first position of the command indicates the command group. This command is in Group 1- Communications Port Control.0The entry in the second position of the command indicates the command subgroup. In this example, all commands with a second digit of 0 apply to the main port.0The entry in the third position of the command is the command digit. In this example, the 0 indicates this command affects the baud rate.5The entry in the fourth position of the command indicates the setting. Normally this is a variable and is usually a hexadecimal value from 0 to 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.

AI1620 SmartPass System Guide5-4Command Response ConventionsLike SmartPass commands, responses are preceded with the # character. Many SmartPass 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 5-2 shows an example of a command/reply sequence. This example assumes that a SmartPass with serial number 97001P running version SP2-ACC 1.03D software is connected to a PC running a terminal emulation software package such as Windows Terminal or ProCom. The command sequence verifies that communications are working correctly.In command discussions, SmartPass response characters may be shown in brackets < >. This indicates that the response is a value in the range of characters. The brackets are not part of the response. For example, the display power fail bit command 520 responds with either a 0 or a 1. In the command discussion, the response is shown as:#PWRB <0-1>The actual SmartPass response is one of the following:#PWRB 0#PWRB 1In the above example, PWRB is the four-character identifier for power fail bit, and the 0 or 1 is the value. All spaces shown in the response are actual spaces sent from SmartPass. In the example above, one space is between the letter B and the number. Table 5-2 Sample Command SequenceEntry SmartPass Response Notes#01 <CR> #Done <CR/LF> Switches SmartPass to command mode#505 <CR> #Model SP2-ACC Ver 1.03D SN97001P <CR/LF> Reports the software version and serial number#00 <CR> #Done <CR/LF> Returns SmartPass to data mode

General Software Information5-55Operating ParametersSmartPass readers maintain their operating parameters in battery-powered RAM so that the parameters will be preserved after a power-down sequence.Power FailThe system maintains a power fail flag. The host transmits display power fail bit (command 520) to determine if a power down has occurred. This flag is cleared by both reset reader (command 63) and reset power fail bit (command 65).Program DownloadProgram download stores the SmartPass applications software into SmartPass’s flash memory. Program download is used to install program upgrades, add features, and to recover from corrupted program data. The download mode supports commands 90, 91, 96, 97, and 99.Download ConsiderationsYou should consider the following items when performing program download:•SmartPass does not process tags while in download mode.•SmartPass accepts only download commands while in download mode. It responds to all other commands with an error message.•SmartPass will not accept any program data unless a successful erase of flash memory has been performed before transmitting the data. Erasing the flash mem-ory typically takes 7 seconds.•Exiting from download mode will re-execute startup. If the new software has been loaded without errors, SmartPass will come up in data mode. If a flash checksum error is detected, SmartPass will reenter download mode and transmit a sign-on message with a software version of 0.00 and without a serial number.Note: SmartPass uses default communication parameters when operating in down-load mode (9600 baud, 8 data bits, 1 stop bit, no parity, basic protocol), and does not echo commands in download mode.

General Software Information5-75StartupUpon startup, SmartPass readers transmit a sign-on message or a boot ROM failure message.Sign-On MessageThe sign-on message should appear as shown below: Model [software version] SNYYYYYY[Copyright notice]where YYYYYY is the serial number assigned to the SmartPass unit being used.Serial number 000000 is the default setting and is not a valid number. If this number appears in the sign-on message, either the battery has failed or the serial number has never been stored into reader memory. The appropriate serial number is assigned using command 695. If the flash memory checksum does not verify, the sign-on message appears as shown below:Model [Model] Ver 0.00[Copyright notice]Boot Failure MessageThe software performs a checksum function on itself. The function returns a specific value for the particular version of software. If the value returned is not correct, the boot ROM checksum assumes that locations have been corrupted, and a failure condition exists. If the boot ROM checksum is not correct, a boot failure message is transmitted. If the failure message does not transmit, a communications error has occurred, or the boot failed to the extent that it cannot transmit the failure message.If the failure message version number equals 0.00 and no serial number exists, the flash memory checksum has failed, and SmartPass is operating out of boot ROM. In this case, SmartPass automatically enters download mode and waits for a new program to be loaded into the flash memory. Follow the instructions in “Program Download” on page 5-5.Tag/Message BufferSmartPass readers maintain a tag buffer in battery-backed RAM to save tag IDs acquired while in the command mode and when data inquiry protocol is used. This buffer holds up to 195 time-stamped messages. Error messages will be transmitted to the host to provide buffer status as it fills. When the buffer fills, subsequent tag IDs will be lost. For more information on how the buffer works, refer to “Command Entry Conventions” on page 5-3 and “6161 Enable Buffer Control Mode” on page 7-28.

Communication Protocols6-36This chapter describes the communication protocols for SmartPass.IntroductionSmartPass supports the following communication protocols:•Basic•Error correcting•Data inquiry The following protocol information provides reference information relevant to developing host software.A two-way message interchange is required in both data mode and command mode when using error correcting protocol (ECP). This interchange is completed by the message recipient returning a message to the sender.With ECP, all transmissions require a message. If a message is not received, the sender will time out with the same effect as if it had received a negative acknowledgment (from the host) or an Error message (from SmartPass).XON/XOFF flow control is optionally supported. Be careful in the use of XON/XOFF because noise-induced characters may be interpreted by SmartPass as the XOFF character, which would suspend reader output without the host computer’s knowledge.Note: Amtech recommends that XON/XOFF flow control be disabled while using ECP.Communications are performed using the 7-bit ASCII code with optional parity, thus providing easy setup, testing, and diagnostics with standard ASCII terminals and serial printers. Parity must be enabled to achieve the specified undetected error rate.Each message is framed with the start-of-message (som) and end-of-message (eom) characters so that the host computer can detect the beginning and end of each message. This convention is most important under marginal communications conditions during which the host may receive extraneous noise-induced characters between reader transmissions. In such instances, the host is able to ignore any messages that do not conform to the som...eom frame sequence.Basic ProtocolWith basic protocol, messages sent from SmartPass to the host are transmitted without error checking. Messages sent from the host to SmartPass are also transmitted without error checking. A Done or Error message is returned to the host by SmartPass for each host transmission.

AI1620 SmartPass System Guide6-4When the host computer is physically close to SmartPass and no sources of interference exist, the basic protocol provides reliable communications.The host must be ready to receive reader-transmitted messages, because in basic protocol SmartPass does not wait for the host to acknowledge a message before transmitting the next message. If necessary, the host may halt reader transmissions by using software or hardware flow control. Refer to Chapter 6, “General Software Information,” for flow control information.Error Correcting ProtocolWherever the quality of data communications is imperative or may be suspect, ECP can be invoked to ensure the integrity of data transmitted between SmartPass and the host. Note: Amtech recommends that basic protocol (not ECP) be used when commands are entered manually at the keyboard.Error correction is accomplished with use of a cyclic redundancy check (CRC) value that is based on the message data. The originator (reader or host) calculates the CRC of a message and includes it in the transmitted message.The recipient (reader or host) also calculates a CRC for the received message. If the transmitted message data is correct, the CRC calculated by the recipient will agree with the CRC calculated by the originator. If the CRCs do not agree, the message is rejected.Message sequence numbers are also included when using the ECP. These sequence numbers are checked to determine if the message received has the correct sequence number; if not, the message is rejected.Since the 7-bit ASCII code is used and there are 8 data bits per character, the eighth bit can optionally be used to support parity. Where parity is selected, the CRC calculation includes the parity of each character in the calculation of the CRC value.Parity is required to achieve the most reliable communications. If parity is enabled, both SmartPass and host must issue a message if any received character has a parity error. However, the message must not be transmitted before receipt of the eom character. SmartPass will issue an Error message and the host a negative acknowledgment message.Data Inquiry ProtocolData 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 SmartPass acquires tags, it buffers them but does not transmit them. Instead, the host must poll SmartPass for each tag by sending a CTRL-E

Communication Protocols6-56character (hex 5 digits). SmartPass 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. SmartPass data transmission (tag ID and report data) format is the same as for basic protocol.Selection of data inquiry protocol does not affect command mode operation.Basic and ECP Protocol FormatNote: In the following text, the symbols < and > are used to represent required vari-able message data, and the symbols [ and ] are used to represent optional data. These symbols are not part of the message syntax.Reader TransmissionsThe basic protocol format and the data inquiry protocol format are shown below.<som><data><eom>The ECP format is shown below.<som><seq><data><crc><eom>where:<som> Start-of-message (ASCII # character)<seq> Sequence number (ASCII hex) that represents an even number in the range 0–9, A–E (0, 2, 4, 6, 8, A, C, E). This number is maintained by SmartPass. The host must acknowledge reader transmissions by sending an ACK message with the same sequence number received from SmartPass. SmartPass will update its sequence number upon receipt of a valid host ACK. If an ACK is not received, SmartPass will retransmit the message. A reader transmission sequence is not considered compete until SmartPass receives an ACK and updates its sequence number.<data> 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 Error02, 03, 04, or 05 message (buffer level report), or a sign-on message. Time, date, and auxiliary data may also be included.<crc> Cyclic redundancy check (CRC). This field contains four ASCII digits that represent the 16-bit CRC calculated on the message. The CRC is calculated on bytes between the som character and the first CRC byte.When the host receives a properly framed message, it can calculate a 16-bit CRC. The calculation is applied to the character

AI1620 SmartPass System Guide6-6string that immediately follows the <som> and that ends with the character immediately preceding the first <crc> character.The transmitted CRC can then be compared with the binary equivalent of the received <crc> characters. If the transmitted and received CRCs are not the same, the message is assumed to have been received in error, and a NAK message response should be transmitted.<eom> End-of-message characters (ASCII CR and LF). Both a carriage return (CR) and line feed (LF) are included to facilitate the use of terminals and printers.If the host receives a <som> character in the middle of a data message, the message in progress must be aborted. The assumption is that an <eom> was lost and SmartPass is in the process of retransmitting the previous message.ECP Host ACK/NAK ResponseWith ECP, the host computer responds to all data message transmissions from SmartPass using the following acknowledgment or negative acknowledgment response format.<som><seq><ack/nak><crc><eom>where:<som> Start-of-message (ASCII # character)<seq> An echo of the sequence number received from SmartPass. The sequence number should correspond to the data message that is being positively or negatively acknowledged by the host. If SmartPass receives an ACK message with the incorrect sequence number, the data message is retransmitted.The host computer is responsible for resetting its anticipated data message sequence number to that of SmartPass before communications can resume without error.<ack/nak> ASCII @ character for ACK response; ASCII ? character for NAK response<crc> CRC for the message<eom> End-of-message character (ASCII CR)SmartPass sets a user-programmable timeout delay at the time each message is transmitted (based on command 612NN, where NN = timeout delay). The timeout delay can be disabled for diagnostic purposes by setting NN = FF.If the timeout delay expires before SmartPass receives an ACK or NAK message from the host, a logical NAK condition will be declared. If SmartPass receives a NAK or timeout, the data message is retransmitted.

Communication Protocols6-76When SmartPass receives an ACK message, the message is treated as having been properly received by the host. The sequence number is then incremented, and pointers are advanced to the next message in SmartPass’s message queue to prepare for sending the next message.Switch to Command Mode RequestThe host may issue command 01 (switch to command mode) while in data mode.The basic protocol format is shown below.<som><cmd><eom>The ECP format is shown below.<som><seq><cmd><crc><eom>where:<som> Start-of-message (ASCII # character)<seq> The sequence number is generated by the host computer separately from that appearing in data messages transmitted by SmartPass.<cmd> Switch to command mode, command number (ASCII characters 01)<crc> CRC for the message<eom> End-of-message character (ASCII CR)Host TransmissionThe host initiates synchronous communications between SmartPass and the host.

AI1620 SmartPass System Guide6-8<seq> Sequence number (ASCII hex digit) that represents an odd number in the range 1–9, A–F. The host should use odd sequence numbers in its command because SmartPass uses even sequence numbers in its transmissions. This method eliminates the possibility of a synchronous host command and an asynchronous reader transmission having the same sequence number.Upon receiving a host command, SmartPass is expected to echo the command’s sequence number in its response. Therefore, the host must update its sequence number upon receipt of a valid reader message. If the sequence number is not updated before transmission of the next command, SmartPass will not service the new command; it will retransmit its previous message. A command/message sequence is not considered compete until the host updates its sequence number.<cmd> Command code, a string that contains from two to four ASCII hex characters[<data>] Optional data field, an ASCII string of as many as 20 characters in length. For example, the set date command is 21MM/DD/YY (command 21 followed by the data string MM/DD/YY).<crc> CRC for the message<eom> End-of-message character (ASCII CR)Reader Command ResponseThe basic protocol format is shown below.<som><resp><eom>The ECP format is shown below.<som><seq><resp><crc><eom>where:<som> Start-of-message (ASCII # character)<seq> Echo of sequence number received in host command message<resp> Response string.

The timeout delays previously described are a function of baud rate.SmartPass supports an ECP timeout, which applies equally to both transmit and receive. In addition, a protection mechanism has been implemented for SmartPass that prevents the assignment of mismatched ECP timeout and baud rate values. SmartPass will not allow the host to alter the ECP timeout (command 612NN) if the specified timeout is too short for the current baud rate. Conversely, SmartPass will not allow the host to alter the baud rate (command 100N) if the specified baud rate is too fast for the current ECP timeout.The receiver’s minimum timeout delay should equal the time to transmit/receive the longest anticipated message at the current baud rate setting. Additional margin should be included for idle periods between characters; for example, processing overhead, if any. The timeout delay period can be expressed as follows:Τrec (ms) = L x [Τchar + Τidle]where:Τchar (ms) 1000 x [ Bc / Rb ]BcBits per character (typically 10)

Communication Protocols6-116RbBaud rate (110–19.2 K)LLength of message in charactersΤidle Maximum idle period between characters (ms)Likewise, the sender must set a timeout delay equal to the delay of nine characters at the current baud rate setting; for example, the time required to shift out the <eom> character plus the time to shift in the ACK or NAK message to be received) plus a processing allowance for the receiver to process the message and check for error conditions.Thus, the sending timeout delay can be expressed as the following:Τsend (ms) = 9 * Τchar + Τerrchkwhere:Τerrckh (ms) Processing period to perform error checking by receiverSmartPass supports baud rates between 110 and 19.2 K. The host can remotely set the SmartPass’s communications parameters while in the command mode, but Amtech does not recommend this action if communications conditions are marginal.After SmartPass receives new communications parameters, SmartPass issues the Done message and switches to the new configuration immediately. It is the host computer’s responsibility to switch its own communications parameters immediately after the transaction is complete.As noted, the message initiator, such as SmartPass in data mode and the host computer in command mode, starts a timeout counter at the time a message is transmitted. If the timeout expires before receiving a message, a logical NAK condition is declared, and the message is assumed to have been received in error. In this instance, the message is retransmitted until a message is received.The message recipient, such as the host computer in data mode and SmartPass in command mode, starts a timeout counter when a <som> character is received. If the timeout expires without the receiver receiving an <eom>, the message acquisition is aborted (reset), and the receiver waits for the next <som> character.If a second <som> character is received before an <eom> character, the message acquisition is aborted (reset), and retransmission of the previous message is assumed to be underway.These strategies are designed to allow for graceful recovery during periods when communications are marginal or completely lost.It should be noted that while SmartPass is in command mode, all acquired tag IDs are buffered but not transmitted.Note: It is important that the host limit the period during which SmartPass remains in command mode to avoid overflowing SmartPass’s tag ID buffer and subsequently los-ing tag IDs.

AI1620 SmartPass System Guide6-12Reader-Addressed Failure ConditionsSmartPass addresses the following failure conditions.Illegal Sequence Number (Not in the Range 0–9, A–F)If SmartPass detects an illegal sequence number in a host command message, it dis-cards the received message and does not send a response. If it receives an illegal sequence number in an ACK message, it responds as if a NAK had been received and retransmits the data.Wrong Sequence NumberIf SmartPass receives the wrong sequence number in an ACK message, it responds as if a NAK had been received (it retransmits the data).Bad CRCIf SmartPass detects a bad CRC in a host command message, it discards the received message. No response is sent. If it receives a bad CRC in an ACK message, it responds as if a NAK had been received, and it retransmits the data.Illegal CommandIf SmartPass receives an illegal command, it returns its standard Error message.Transmission TimeoutIf SmartPass transmits an asynchronous message and the host does not send an ACK before the ECP timeout occurs, SmartPass retransmits the message.Receive TimeoutIf SmartPass receives a <som> but does not receive a matching <eom> before the ECP timeout occurs, it discards the incomplete message and resets its receiver.Asynchronous Message/Command Message CollisionIf SmartPass transmits asynchronous data at the same time that the host sends a command, SmartPass gives priority to receiving the command. It processes the command and sends a message before it retransmits the asynchronous data.Host-Addressed Failure ConditionsThe host addresses the following failure conditions.Illegal or Wrong Sequence NumberIf the host detects an illegal or wrong sequence number in a reader response, it retrans-mits 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.

Communication Protocols6-136Bad CRCIf the host detects a bad CRC in a reader message, it retransmits the command with the same sequence number. If the host detects a bad CRC in an asynchronous reader trans-mission, it transmits a NAK message.Transmission TimeoutIf SmartPass does not respond to a host command within a specified interval, the host retransmits the command with the same sequence number.Receive TimeoutIf the host receives a <som> but does not receive a matching <eom> within a specified timeout interval, it discards the incomplete message and resets its receiver.Asynchronous Message/Command Message CollisionIf the host receives an asynchronous reader transmission at the same time it transmits a command, it ignores the asynchronous message and waits for SmartPass’s response. SmartPass retransmits asynchronous data after it transmits the command message.ECP ReliabilityAn 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.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 CalculationThe CRC used by the ECP is based on a 16-bit algorithm. The algorithm, as implemented, operates on 8-bit characters; for example, 7-bit ASCII character plus 1optional parity bit. The 16-bit result is converted to 4 ASCII hex characters and is appended to messages transmitted by SmartPass.SmartPass accepts 4 ASCII < ` > characters (60 hex) as a wild card CRC in lieu of a valid 4-character CRC to facilitate testing and diagnostic checkout.SmartPass implements the algorithm with a 512-byte lookup table to reduce the processing overhead requirements. To simplify the implementation of the CRC algorithm by host software developers, several examples of the calculation are provided in C source code in Table 7-1 through Table 7-4. The calculation may be performed with or without a lookup table, depending on the trade-off between code memory and processing overhead.

$AI1620 SmartPass System Guide6-14Table 6-1 presents an example of a function (CALCCRC) that calculates the CRC through a call to a separate function (UPDCRC). Table 6-2 shows an example of UPDCRC that does not require a lookup table. Table 6-3 contains an example of UPDCRC that does require a lookup table. Table 6-4 shows an example of a function that creates the lookup table.Table 6-1 Example of Routine to Calculate CRCunsigned short calccrc(char *message){unsigned short crc = 0;for ( ; *message != (char)0;message++) crc = updcrc(*message & 0xff, crc);return (crc)}Table 6-2 Example of Routine to Calculate CRC-CCITT without Lookup Table#define BITS_PER_CHAR 8unsigned short updcrc (unsigned short ch, unsigned short crc){register short counter = BITS_PER_CHAR;register short temp = crc;while (--counter >= 0) if (temp & 0x8000) {temp <<= 1;temp += (((ch <<= 1) & 0x0100) != 0);temp ^= 0x1021; } else {temp <<= 1;temp += (((ch <<= 1) & 0x0100) != 0); }return(temp);}$

Commands7-37This chapter discusses the host-transmitted commands that are used to control SmartPass configuration and operation.IntroductionSmartPass is delivered from the factory with specified default settings that determine how SmartPass operates. These settings can be changed and additional features can be controlled by commands transmitted by the host. The commands can be transmitted with specialized host software or by manually entering the commands at the host keyboard if the host is in terminal emulation mode. SmartPass can also communicate with ASCII terminals and printers. Note: If you are using Wiegand mode, you must connect the PC, laptop, or terminal emulator to SmartPass using the RS-232 or RS-422 interface before attempting to send commands to the reader. You can leave the Wiegand interface connected during this procedure. Operating ModesSmartPass has three modes of operation: data mode, command mode, and download mode. The software for SmartPass contains two separate programs — one in boot ROM and one in flash EPROM. The boot ROM program has control of SmartPass on startup and when operating in download mode. The flash EPROM program has control of SmartPass during data mode and command mode operation and holds the application code. Together, they control SmartPass in the three modes of operation.Data ModeSmartPass is in the data mode upon power-up. While in the data mode, SmartPass sends all communications as data messages, such as tag IDs and reports, to the host computer. Reports provide information on input status changes (input0 and input1), a presence without tag report, and buffer overflow information. The host computer can send only three commands to SmartPass while in data mode: •Command 01 — switch to command mode — changes SmartPass from the data mode to the command mode. See “01 Switch to Command Mode” on page 7-5.•Command 05 — switch to download mode — allows the host computer to down-load new software into SmartPass. See “05 Switch to Download Mode” on page 7-6.•Command 8110 — perform system check tag test — performs a single system check tag test. See “8110 Perform System Check Tag Test” on page 7-41. Note: SmartPass transmits tag identification (ID) codes to the host computer when SmartPass is in data mode. If SmartPass is left in the command mode too long, the tag

AI1620 SmartPass System Guide7-4buffer will fill up and any additional tag IDs will be lost. You must return Smart-Pass to data mode as soon as possible to ensure proper transmission of acquired tag IDs. For information on the data mode, refer to the “Data Mode” on page 7-3. For information on the tag buffer and buffer control, refer to “6160 Disable Buffer Control Mode (Factory Default)” on page 7-27 and “6161 Enable Buffer Control Mode” on page 7-28.Command ModeWhile in the command mode, the host computer sends commands to SmartPass. Host-transmitted commands can be used to control the operation and configuration of the reader. After SmartPass receives a command, it transmits a command response message. Typically, the command message contains Error, Done, or data relating specifically to the command request. These messages may be of variable length since some commands require information as part of the message; for example, time and date. The host computer sets a timeout delay when the command is transmitted to SmartPass. If the timeout delay expires before the host receives a command message from SmartPass, a logical NAK condition is declared. The host then retransmits the command request message. Communications can be lost if the host computer attempts to send certain commands under marginal communication conditions. For example, if the host computer transmits the command request to change the baud rate and SmartPass properly receives the request and transmits the Done message, one of the two conditions described below may occur.If the host computer receives the Done message, then both the host and SmartPass switch to the new baud rate, and communication is maintained. Note: SmartPass changes the baud rate immediately after issuing the Done mes-sage.However, if the Done message transmitted by SmartPass is not received by the host, the host would assume that the command was not properly sent and would not switch to the new baud rate.CautionBecause this condition would lead to a loss of communications, the host should not attempt to change communications parameters or protocols during mar-ginal communications conditions.

Commands7-57Download ModeIn download mode, SmartPass allows the host to download new software and supports a limited set of commands — #90, #91, #96, #97, and #99. SmartPass does not process tags while in download mode. See “90 Load Program Block” on page 7-42 through “99 Exit Download Mode” on page 7-43.Command ListReader commands are divided into eight groups based on primary function. The following sections provide information about each command in command number order. Refer to Appendix D for a listing of commands in alphabetical order.Note: In the following text, the symbols < and > represent required variable message data. These symbols are not part of the message syntax.Reader Mode Control — Command Group 0 Group 0 commands control reader mode. The mode determines whether the reader is transmitting data to or receiving data from a host computer or terminal.00 Switch to Data Mode (Factory Default)Command 00 switches the reader to data mode, which allows the reader to transmit tag data (ID codes) to the host. The reader enters data mode on power up.While operating in data mode, the reader accepts the following commands: •Switch to command mode (01)•Switch to download mode (05)•Invoke check tag (8110)Reader message:Done01 Switch to Command ModeCommand 01 switches the reader to command mode, which allows the reader to accept commands from a host or terminal. While in command mode, the reader does not transmit tag IDs to the host as they are acquired. The IDs are stored in the reader’s tag buffer for transmission when requested by the host.While operating in command mode, the reader continuously monitors the level of its tag buffer. If the buffer becomes 75% full, the reader transmits an Error 04 message to the host. If the buffer becomes 100% full, it transmits an Error 02 message. When the buffer is full, incoming tag IDs cannot be buffered, and they are lost. The reader does not resume asynchronous tag transmission until it is returned to data mode (command 00). Upon return to data mode, the reader begins to empty the tag buffer. When the

AI1620 SmartPass System Guide7-6buffer is no longer full, the reader transmits the Error 03 message indicating that the tag buffer has been partially cleared, and new IDs are again being stored. When the buffer has emptied to 50%, the reader transmits the Error 05 message.Reader message:Done05 Switch to Download ModeCommand 05 switches the reader to download mode, which allows an external host computer to download new software into the reader flash memory.While operating in download mode, the reader accepts a limited set of commands: load program block (90), verify flash checksum (91), erase flash memory (96), perform destructive memory test (97), and exit download mode (99).Note: While in download mode, the reader communication port parameters are fixed at the following factory default settings: 9600 baud, 8 data bits, 1 stop bit, no parity, software flow control (XON/XOFF), basic protocol.While in download mode, the reader does not echo host commands.To exit the download mode, the host must transmit exit download mode command 99. The reader re-executes startup to ensure proper initialization of operating parameters and to verify the boot ROM and flash memory checksum values. The reader does not accept the switch to download mode command 05 if it is operating in data mode; it must first be switched to command mode (command 01).Reader message:Done or Error 06 Transmit Buffer EntryCommand 06 allows the host to request data (tag IDs and reports) from the reader. This command is supported if ECP is selected (command 611) and buffer control has been enabled (command 6161). If the reader receives command 06 and it has data in its message buffer, it transmits the buffered message of highest priority. Report data is not transmitted until all tag IDs have been transmitted. If the reader’s message buffer is empty, it sends the Done message. The reader returns an Error message if it receives this command when ECPand/or the buffer control have not been enabled.Reader message:Done Buffer emptyError Buffer control mode not enabledMessage IDs or reports in buffer

Commands7-77Communications Port Control — Command Group 1Group 1 commands configure the parameters used by SmartPass to communicate with a host computer or terminal. These commands set baud rate, stop bits, parity, and end-of-line delay.100N Select Baud RateCommand 100N selects the reader baud rate. The factory default setting is 9600 baud.

The reader is set at the factory to append time and date to all IDs. Auxiliary information, such as reader number, antenna number (or manual entry code), number of times the previous tag was read, and sensor input status can also be appended to the ID using the Group 3 commands.

AI1620 SmartPass System Guide7-1030N Append Time and Date SelectionThis command 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 be lost. If this is unacceptable, allow the buffer to empty before re-issuing append time and date command 30N.The reader transmits messages with time and date appended as follows. One space separates the time from the date.<string>&<HH:MM:SS.hh MM/DD/YY>where:string is a tag ID, error message, or report.& separates <string> from the time and date.HH:MM:SS is the time delimiter.MM/DD/YY is the date delimiter.Reader message:Done or Error31N Append Auxiliary Information SelectionThis command selects the option of appending auxiliary information to transmitted IDs, presence without tag reports, and input status change reports.

These values are inverted if input inversion is enabled with command 6941.Reader message:Done or ErrorID Filtering — Command Group 4Group 4 commands set criteria for filtering (buffering or discarding) ID codes. These commands are useful for eliminating duplicate ID codes and filtering unwanted IDs obtained from fringe areas of the SmartPass read zone. 40 Transmit All ID CodesCommand 40 instructs the reader to transmit all IDs without regard for uniqueness. Note: Command 40 is for diagnostic purposes only. The tag buffer must be empty before the reader accepts this command.After diagnostics are complete, reinstate the uniqueness check using select unique ID code criteria (command 410N).Reader message:Done or Error410N Anti-Passback (Select Unique ID Code Criteria)This command instructs the reader to buffer and transmit ID codes according to the following test: an ID is buffered if, in the time interval since the new ID was last received, previously decoded IDs have changed value at least N+1 times, or the

AI1620 SmartPass System Guide7-12uniqueness timeout has occurred. IDs that do not pass the test are not buffered. The factory default setting is command 4100, which selects a separation of one ID.Each time the reader receives a tag ID, it compares the ID with the contents of a comparison register. This register contains the following two items:Item 1 Most recently acquired IDItem 2 Second-most recent ID (if different from item 1)When the uniqueness filter is set to a separation of one ID, the newly acquired ID is transmitted only if it is different from item 1. When the uniqueness filter is set to a separation of two IDs, the newly acquired ID is transmitted only if it is different from both items 1 and 2.Note: A new ID can fail the filter test and not be transmitted; however, it remains stored in the comparison register.The uniqueness test has a 2-minute time limit. If an ID is buffered, it will not be accepted again unless it arrives at the reader more than 2 minutes from the previous arrival or until the receipt of one or more other IDs reset the uniqueness. Reader message:Done43 Buffer All ID CodesCommand 43 buffers all acquired ID codes. It effectively cancels any uniqueness criteria previously set by select unique ID code criteria command 410N. Note: Command 43 is for diagnostic purposes only.After diagnostics are complete, reset the select unique ID code criteria using command 410N.Reader message:Done450 Disable Wiegand Mode (Factory Default)Command 450 is a default set in the factory to disable Wiegand mode.

Refer to “Error Correcting Protocol” on page 6-4 for more information.Reader message:Done or ErrorCautionDo not switch to error correcting protocol (command 611) unless the host is pre-pared to acknowledge each reader transmission.612NN Select Error Correcting Protocol TimeoutCommand 612NN selects the timeout interval for ECP. This timeout applies to the transmission of tag, report, and error messages and to the receipt of host 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 will time out and retransmit 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 will discard the partially received message and reset its receiver.The value for NN specifies the timeout interval as follows:ms 50 * NN for NN = 01 to FE (1–254)FE factory default (12,700 ms, 12.7 sec)FF disables the error correcting protocol timeoutUppercase or lowercase characters are allowed for NN; for example, hex digits A–F or a–f.Reader message:Done or ErrorA protection mechanism prevents the assignment of mismatched ECP timeout baud rate values. The reader transmits Error in response to command 612NN if the specified timeout (NN) is too short for the current baud rate. Refer to “Timing and Synchronization” on page 6-10 for more information.

Commands7-277613 Select Data Inquiry ProtocolCommand 613 selects the data inquiry protocol. Refer to “Data Inquiry Protocol” on page 6-4 for more information.Reader message:Done or Error614N Select Flow Control OptionThis command selects the flow control option for reader-to-host communications. The factory default setting is software flow control (XON/XOFF) enabled. In download mode, flow control is not host-selectable; it is fixed at the default setting. However, during data mode and command mode operation, the following flow control options are available.Reader message:DoneIf the reader is configured for software flow control (XON/XOFF), it stops transmitting if it receives an XOFF character (command 13H). It will not resume transmitting until it receives an XON character (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. It will resume transmission when this line is asserted again.Note: Amtech recommends that XON/XOFF flow control be disabled while using the ECP.6160 Disable Buffer Control Mode (Factory Default)Command 6160 is used to disable buffer control. Buffer control is an ECP option that prevents unsolicited (asynchronous) reader transmissions. If buffer control is not active, the reader transmits data to the host as soon as the data is acquired. The host must acknowledge the data according to the ECP acknowledgment/negative acknowledgment (ACK/NAK) protocol. Refer to command 6161 for more information.Reader message:DoneCommand Flow Control Option6140 Disable flow control6141 Enable software flow control (factory default)6142 Enable hardware flow control

AI1620 SmartPass System Guide7-286161 Enable Buffer Control ModeCommand 6161 is used to enable buffer control. Buffer control is an ECP option that prevents asynchronous reader transmissions. When buffer control is enabled using command 6161, the reader transmits only in response to command 06, transmit buffer entry. The exception to this rule occurs on startup when the reader transmits its two-line sign-on message asynchronously. The following commands are used for buffer control:If BCM is enabled, the host must request tag IDs and reports from the reader using the transmit buffer entry command 06. If the reader receives this command and it has data in its buffer, it will transmit the buffered message of highest priority (tag IDs first and then reports). If the reader’s buffer is empty, it will transmit the Done message instead. The reader will return an Error message if it receives command 06 when BCM is not enabled.If buffer control is enabled, the reader will not support ECP ACK or NAK messages from the host. Since all messages are transmitted in response to a host command, acknowledgment from the host is not required. Instead, the ECP sequence numbers are used to ensure data integrity. If the host receives an erroneous reader message, it should retransmit command 06, transmit buffer entry, with the same sequence number. This will cause the reader to search and replace its previous message. If buffer control is enabled, the reader will not use the timeout to trigger re-transmission of data because in buffer control, reader data is transmitted only when requested by the host. Reader message:DoneNumber Command Description Message06 Transmit buffer entry Done, error, or <message>535 Display buffer control status where x= 0 for disabled 1 for enabledBCM x6160 Disable buffer control mode (default) Done6161 Enable buffer control mode Done

Commands7-297Buffer Control Error MessagesThe error messages shown in the following table are transmitted based on the content level of the tag buffer. These messages are transmitted in data mode and command mode. They will not be transmitted if uniqueness checking has been disabled to transmit all IDs (command 40) or buffer all IDs (command 43).If the buffer fills up and then transmission is re-enabled, the sequence of transmitted reports would be as follows:Error 04 75% fullError 02 100% fullError 03 emptied to less than 100%Error 05 emptied to 50% or less6170 Disable Echo ModeCommand 6170 disables the reader’s echo of received host commands. If operating in basic protocol or data inquiry protocol, the reader echoes by default. As the reader receives a host command, it echoes each character of the command. Once the entire command has been received and processed, the reader transmits its response. If echoing is disabled with command 6170, the reader will not echo the command but only transmits its response. The reader never echoes while in ECP or download mode operation.Reader message:DoneError Message Buffer StatusError02 Tag buffer is full. Incoming IDs cannot be buffered. An overflow of the tag buffer can occur if SmartPass is left in command mode or if flow control has disabled transmission. A buffer overflow results in subsequent tag IDs being lost. Error03 Tag buffer has been partially cleared and new IDs are once again being stored.Error04 Tag buffer has filled to 75%.Error05 Tag buffer has emptied to 50%.

Installing SmartPass8-138Connecting the AC Power SupplyTo connect SmartPass to a low-voltage AC power supply, perform the following steps. 1. Connect the SmartPass power wires from the cable to the transformer using the cable coding as described in Table 8-3. 2. Complete the power connections at the power supply.Table 8-3 AC Transformer Connections for Colored Pair Wire CableSignal From SmartPassColored Pair Wire CableWire Pair from Color SmartPass UsedConnect to Transformer Terminal StripMain power input Brown/Red and Orange/RedBrown and Orange L1Main power return Red and Red L2

AI1620 SmartPass System Guide8-14Connecting the DC Power SupplyTo install SmartPass using low voltage DC connections, use the connection designations shown in Table 8-4. Marking the Read ZoneThe antenna pattern, or read zone, of SmartPass would look roughly like a pear-shaped balloon if you were able to see it. When installing SmartPass, you will first mark the unit’s read zone with the RF range set at the factory default maximum. You can then adjust the read zone using the techniques discussed in “Fine-Tuning and Verifying the Read Zone” on page 8-16.If two SmartPass readers are installed near each other, Amtech recommends that you fine-tune each SmartPass for the ideal read zone before connecting it to permanent sense input/sense output and communications cables. Materials RequiredTo mark the read zone, you will need the following items:•SmartPass software diskette, which is supplied to Amtech dealers and distributors, or any terminal program running on a PC•PC or laptop with 1.44 MB floppy disk drive, MS-DOS, RS–232 serial port, and a communications cable with a DB9 or DB25 connector•Test tag, supplied by the Amtech dealer or distributor•Communications cable to connect to the COM1 port on your PCTable 8-4 Low Voltage DC Cable Connections for the Colored Pair Wire CableSignal from SmartPassColored Pair Wire CableWire Pair from Color SmartPass UsedConnection UseMain power input Brown/Red and Orange/RedBrown and Orange 16 to 28 V DC + terminalMain power return Red and Red 16 to 28 V DC – terminal

Installing SmartPass8-158•Audible circuit tester and 9 V DC battery for circuit tester power as described in the section, “Testing SmartPass” on page 4-6.•Piece of chalk or roll of tape•Plastic or wooden yardstick•Vinyl electrical tape or hook-and-loop materialMarking ProceduresFollow the steps below to mark the read zone:1. Connect the red and white leads from the audible tester to the red and white pair of wires from the SmartPass cable. 2. Twist together the red and green pair of wires from the SmartPass cable to turn on continuous RF power. 3. Secure the test tag to the end of the yardstick using electrical tape or hook-and-loop material. Be sure the tag polarization matches that of the SmartPass when the yardstick is held upright.4. Stand directly in front of and about 5 ft (1.5 m) away from SmartPass. Hold the stick so that the tag is positioned at a height and angle consistent with a tag installed on a vehicle. The test tag should cause the audible tester to sound.Note: If you hold the test tag in your hand, your hand will absorb the RF signal and the test results will be incorrect.5. Move to the left until the sound stops.6. Mark the ground with chalk or tape at the location of the tag when the sound stopped.7. Step backward 1 to 2 ft (0.3 to 0.6 m) and repeat Steps 5 and 6. 8. Continue moving the tag back and forth in this manner, placing marks on the ground to identify the boundary of the read zone each time the sound stops. Continue moving the tag to various locations until the read zone is fully marked.The marks on the ground will indicate the area, called the read zone, where SmartPass reads tags at the current RF range. Figure 8-10 is a view of an ideal read

AI1620 SmartPass System Guide8-16zone within a controlled lane. The x marks show the outside edges of the read zone.Figure 8-10 Sample Read Zone Marking Pattern9. Standing at the farthest point of the pattern, walk toward SmartPass and listen for a continuous sound from the audible tester. If the sound is not continuous, it could indicate a weak or “patchy” RF pattern. See the section, “Fine-Tuning and Verifying the Read Zone” on page 8-16, to adjust the read zone.Fine-Tuning and Verifying the Read ZoneIf the read zone is too wide or too deep, it can be fine-tuned by changing the angle of SmartPass or by changing the RF range. Physically adjusting SmartPass and changing the RF range can confine the read zone to the area of the single lane where tagged vehicles are expected to pass. Fine-tuning the read zone also helps prevent SmartPass from reading tagged vehicles in adjacent lanes or parked behind or next to a SmartPass unit. You can make the read zone smaller by adjusting the RF range down from the factory default (maximum range). The range can be adjusted through a host command or using SmartPass Host.

Installing SmartPass8-178Use the following procedure to adjust the RF range using SmartPass Host, included on the software diskette supplied to dealers and distributors.1. Connect the laptop PC to SmartPass and load SmartPass Host, as discussed in “Connecting SmartPass to the PC” on page 4-7, and “Loading and Starting SmartPass Host” on page 4-15.2. Have another person hold the test tag at the farthest distance at which you want SmartPass to read a tag. 3. Select the Tag & RF drop-down menu and click on the RF Range command. This displays the Range Value dialog box, as shown in Figure 8-11. Figure 8-11 Range Value Dialog Box4. Type in a value from 0 to 31, with 31 being the maximum (default). Smaller entries decrease the read zone size; larger entries increase the read zone size. Click on the OK button to make the change. 5. Follow the steps in the section, “Marking Procedures” on page 8-15, to mark the new read zone on the ground with the tape or chalk. 6. With SmartPass Host running, place one tag behind your back while you hold another tag in the read zone. If a good read is accomplished, the data from the tag held in the read zone will be displayed on the PC screen.7. Switch tags, placing the other tag behind your back and holding the first tag in the read zone. If a good read is accomplished, the data from this tag held in the read zone will be displayed on the PC screen.8. If both tags read successfully, you are ready to connect communications to the junction box terminal. If one or both tags did not read, follow the suggestions in the ‘Verifying Tag Read Capability’ section on page 4-20.

AI1620 SmartPass System Guide8-189. As a last test, attach test tags to vehicles and simulate traffic going through the read zone to verify that the system performs accurately in a live environment. Connecting CommunicationsAmtech offers reader communications through RS–232, RS–422, and Wiegand interface protocols. This section provides the procedures for connecting the communications to the junction box and to the sense input and sense output circuits.Before connecting the SmartPass communications cable to the junction box, Amtech recommends that you test and configure SmartPass hardware and software as presented in Chapter 4, “Testing and Configuring SmartPass Before Installation.” All the wiring tables are also shown in Appendix C, “Wiring Tables.” Connecting SmartPass to the PCSmartPass communications and customer interface signals are supplied from SmartPass to the host through a multiwire cable, which is a 13- or 15-pair pigtail. The connector for this cable is located on the back of SmartPass. Refer to the following sections to connect the appropriate wires from the communications cable to the terminal strip that is located inside the junction box.This section contains instructions for connecting RS-232, RS-422, and Wiegand communications between SmartPass and the PC. Each section contains wiring instructions and pin assignments followed by step-by-step connection procedures. SmartPass does not need to be powered down before attaching it to the PC. Using a RS-232 InterfaceThis section contains instructions for connecting SmartPass to a PC using an RS–232 interface. RS–232 interface signals are supplied by five wires from the SmartPass communications cable. The pin assignments for the signal to the host male DB9 and DB25 connectors are shown in Figure 8-12.

AI1620 SmartPass System Guide8-22If you are using a terminal emulator, use command 451 to configure SmartPass to Wiegand interface. 1. Power down the PC.2. Disconnect the connection between SmartPass and the PC, laptop, or terminal emulator.3. Follow the directions in the “Connecting Colored Wire Pair Cable” on page 8-22 to connect the interface. Connecting Colored Wire Pair CableTable 8-7 lists the Wiegand signals and the interface wires.To connect the interface perform the following steps.1. Connect the blue wire (data0) from the blue and red SmartPass wire pair to the data0 wire of your Wiegand device.2. Connect the red wire (data1) from the blue and red SmartPass wire pair to the data1 wire of your Wiegand device.3. Connect either the yellow or black wire from the yellow and black wire SmartPass wire pair to your Wiegand device logic ground.Note: The RS–232 or RS–422 interface is still included on SmartPass even when you use the Wiegand configuration. Pull the RS–232 red/black wire pairs to a convenient location and tape the ends. Do not cut these wires. If you cut the wires, you may not be able to use them in the future for testing, setting frequency, or adding additional functions.Connecting Sense Input and Sense Output Circuits SmartPass has two sense input circuits and three sense output circuits available. The sense input circuits can be used to notify SmartPass of external events and are designed to be connected to a free-of-voltage dry contact. Sense output circuits are single-pole, double-throw relays that provide normally closed and normally open dry contacts.Table 8-7 Wiegand Interface Signal Wiring for Colored Wire Pair CableSignal from SmartPassColored Pair Wire CableWire Pair from Color SmartPass UsedConnect to Signal from HostWiegand Zero Output Blue/Red Blue Data0Wiegand One Output Red Data1Signal Ground Yellow/Black Yellow or black Ground

Installing SmartPass8-238The following sections provide information to connect the sense input and sense output circuits. Connecting Sense Input CircuitsSmartPass supports two sense inputs — sense input0 and sense input1. This requires two sense input lines for each loop sense or a total of four sense input connections. Sense input0 is the presence detection device line and is used to control RF power. Sense input0 is through the green/red wire pair on the I/O pigtail. SmartPass expects the sense input0 circuit to close when a vehicle is present (i.e., a normally open condition). The minimum presence true period is fixed at 0 ms, which indicates that no delay occurs in closing the circuit when a vehicle is present.Sense input1 is not used directly by SmartPass. Sense input1 is under the host computer’s control.Connecting Sense Output Circuits SmartPass supports three sets of sense output signals. Two sets (sense output0 and sense output1) provide normally open or normally closed sense outputs. The third sense output set is dedicated for testing and setup of the reader. It is defined as the TAG_LOCK signal, which indicates when a valid tag is in the read field.These sense outputs are dry contacts that provide normally open and normally closed sense outputs. The relay contacts are rated at 30 Vrms or 60VDC at 1A, maximum.As illustrated in Figure 8-13, sense output0, normally closed, is located on the orange/black pair. Sense output0, normally open, is located on the brown/black pair.Figure 8-13 Sample Circuit ConnectionsIn Wiegand mode operation, the sense outputs are not controlled by a predefined output mode.

AI1620 SmartPass System Guide8-24Table 8-8 lists the cable descriptions and functions for the interface signals. These wire pairs can be used or terminated based on the specific project applications.Connect the remaining wires to the appropriate terminal blocks on the terminal strip in the junction box. As a guide to the functions of each of the wire signals, use Table 8-8 if SmartPass has the colored wire pair cable.

Troubleshooting and Maintenance9-39This chapter includes information for troubleshooting SmartPass and performing minimal maintenance checks. It also includes information for returning products for repair, obtaining support, and a contact for providing feedback and suggestions to Amtech.Error MessagesSmartPass transmits an error message if a command received from the host is not a recognized command, or if information supplied with the command is not correct. The reader sends this message to diagnostic commands if the reader fails the specified test.Table 9-1 contains a list of error messages. Messages Error02 through Error05 are transmitted based on the content level of the tag buffer. They will not be transmitted if uniqueness checking has been disabled to transmit all IDs (“40 Transmit All ID Codes” on page 7-11) or buffer all IDs (“43 Buffer All ID Codes” on page 7-12). For a detailed explanation of buffer control and its associated error messages, refer to “6161 Enable Buffer Control Mode” on page 7-28. Table 9-1 Error Messages Error Message Description Corrective ActionError02 Tag buffer is full. Incoming IDs cannot be buffered. An overflow of the tag buffer can occur if SmartPass remains in command mode or if flow control has disabled transmission. A buffer overflow results in subsequent tag IDs being lost. Put SmartPass in data mode and/or reset flow control to XON. Ensure command 43 (Buffer all IDs) is not enabled.Error03 Tag buffer has been partially cleared, and new IDs are once again being stored. Error03 will only be issued if Error02 has been issued first. No action necessary; the previous error has been corrected. However, a significant number of tag IDs still remain in the buffer, so continue to monitor the status for a while to ensure the problem does not return. Error04 Tag buffer has filled to 75%. If SmartPass is in command mode, switch to data mode as soon as possible or risk losing some tag IDs. If flow control has disabled transmission (XOFF), reset to XON. Error05 Tag buffer has emptied to 50%. Error05 will only be issued if Error04 has been issued first.No action necessary; the previous error has been corrected. However, a significant number of tag IDs still remain in the buffer, so continue to monitor the status for a while to ensure the problem does not return.

AI1620 SmartPass System Guide9-4Error06 NVRAM parameters have been lost. SmartPass will not function properly because the RF section is shut off until the frequency is reset using command 642.Reset the frequency using command 642. Error07 The RF PLL has lost lock and is unable to operate at its intended frequency. RF output is disabled while SmartPass attempts to reset the PLL.Reset the RF frequency. Refer to “Radio Frequency” on page 4-27 for instructions. Error08 The RF PLL has successfully regained lock and has been reset to its proper operating frequency. The RF section is returned to its state prior to losing lock (enabled/disabled). Error08 will only be issued if Error07 has been issued first.No action necessary; the previous error has been corrected. Error09 SmartPass software has detected an old or unsupported version of SmartPass hardware and will not function. SmartPass is immediately placed into download mode after issuing this message.

Troubleshooting and Maintenance9-59TroubleshootingThe following table can be used for troubleshooting. Should problems continue after referring to Table 9-2, consult your SmartPass Dealer’s Guide for return and replacement procedures. Table 9-2 Symptoms and RemediesSymptom Number*Symptom Remedy1When performing a quick test of SmartPass, the buzz box does not buzz.Check all your wiring connections, and check that your buzz box is functioning. The wires from SmartPass are grouped in pairs. You could find more than one red wire, more than one black wire, and so on. You must connect the correct red and white wire pair to the leads from the battery. Verify that the red/green wire pair is still twisted together as described in Chapter 4. Twisting the red/green wire pair turns on a continuous RF signal.2The baud rate is selected automatically from the DEMO menu on the SmartPass software diskette, but nothing happens.SmartPass is not communicating with your PC. Check the power supply to your PC, and check the connections between the PC and SmartPass. Try reversing the receive and transmit connections.Verify that the red/green wire pair is still twisted together.3When testing SmartPass, all the wires are connected correctly, but the unit does not respond. SmartPass may not have the software loaded inside the unit. Obtain the SmartPass software diskette from your dealer and using your PC, load the software into the system.If you are using a terminal emulation program, check that the terminal emulation setting on SmartPass is VT100.Check that the SmartPass communication cable is connected to the correct COM port. 4Strange signal responses come from SmartPass when tested with the PC.Check the system defaults using the SmartPass software diskette that is supplied to the dealer or distributor. Your system should be set to 9600 baud, 8 bits, 1 stop bit, and no parity.5When a tag is moved in front of the reader, a clicking sound comes from SmartPass.SmartPass works! You hear the relay inside SmartPass that is controlled by a lock signal. The relay is actuated when a tag is in the read zone.6Nothing happens when the test tag is passed in front of SmartPass.Ensure that the red/green pair of wires is twisted together to turn on the RF power continuously. Ensure that SmartPass is powered on and is in predefined output mode.

$AI1620 SmartPass System Guide9-6*Use this number to reference the problem you are having with SmartPass if you call Technical Support. 7SmartPass came from another site and does not work the way the factory defaults indicate that it should.Different commands were probably used to support the other site’s specific configuration. You can restore the defaults by first disconnecting the power. Next, twist the red/black pair of wires together and power up the SmartPass for 3 or 4 seconds. The factory defaults will be restored.8When connected to a PC that is running terminal communications software, a just-powered up SmartPass displays one of the following messages: #Model SP-ACC Ver 2.00D SNYYYYYY #[Copyright notice]SmartPass works! The software is now loaded. YYYYYY is the Amtech-assigned serial number for this SmartPass. However, if YYYYYY = 000000, the internal battery has failed, or a serial number has never been assigned. If the internal battery has failed, the SmartPass must be returned to the factory for replacement. If a serial number has not been assigned to SmartPass, you can assign a unique serial number by using command 695. Note that each SmartPass unit must have its own unique serial number.9The read zone is too small, even before the range control has been adjusted.If another SmartPass is in the same area, be sure it operates on another frequency that is at least 6 MHz different.Check for possible interference from another nearby RF source: fluorescent lights, neon signs, high voltage power lines, nearby cellular telephone, or radio stations. Lights will need to be removed or shielded. Point SmartPass in a different direction to see if interference comes from only one direction. You may require a different SmartPass that uses another frequency.Verify that the range adjustment is set to the maximum. 10 The perimeter of the read zone has been defined, but there is a “hollow” spot in the center of the zone that does not read tags.The angle of SmartPass may need adjustment. Slightly tilt SmartPass to a different angle to change either the length or width of the read zone.Check the range control adjustment. See “Radio Frequency” on page 4-27. 11 SmartPass is reading tags out of the desired read zone, or cross-lane reads are occurring.Some interference from other RF or electrical sources may be occurring. See “Reflection, Refraction, and Diffraction of RF Signals” on page 2-12. 12 How do I download the SmartPass software diskette? To download SmartPass software, you will need a SmartPass software diskette with READ.ME, DL.EXE, and the software file. Insert the demonstration diskette into your PC, and print the instructions on the READ.ME file.13 SmartPass is not providing any output to the Wiegand interface.Ensure SmartPass is in Wiegand mode. The default is either RS-232 or RS-422 mode; refer to “Using Wiegand Interface” on page 4-10. Table 9-2 Symptoms and RemediesSymptom Number*Symptom Remedy$
