Intellitag® 500 SmartPass® Reader System ModificationsF-3FThis appendix describes the changes made to the AI1620 SmartPass® Reader to make the system guide usable for the Intellitag® 500 SmartPass Reader system.IntroductionThis addendum to the AI1620 SmartPass® System Guide provides information about hardware and software modifications for the Intellitag 500 SmartPass Reader system.AudienceThis document is intended to be used by authorized SmartPass dealers, installers, and service personnel. Because SmartPass has no operator- or end-user-serviceable components or features, no end-user manual or operator guide exists. Once the system is set up and tested by the authorized installer, SmartPass operations requires no end-user intervention.Reader ModificationsThe following sections describe the proposed modification and reason for each of the Intellitag 500 SmartPass Reader system changes. Each section lists the modification, the background of the reason for the change (if provided), and the firmware commands affected by the change (if applicable).Reading of Mixed Population TagsModificationThe Intellitag 500 SmartPass Reader reads the American Trucking Association (ATA) or International Organization for Standardization (ISO) read-only type tags, whether battery or beam powered, or Intellitag 500 asynchronous integrated circuit (ASIC)-based tags. The reader can read the ATA or ISO read-only tags in the presence of Intellitag 500-based tags; however, attempting to read a Intellitag 500-based tag in the presence of an ATA or ISO read-only tag might provide indeterminate results. At present, Amtech is aware that the performance under these conditions is strongly determined by physical and geometrical factors.BackgroundThe traditional Amtech read-only tags are continuously modulating regardless of the state of the reader or Intellitag 500 tags. Therefore, when a polling request signal is sent from the reader to the Intellitag 500 tags, it is probable that the read-only tags can interfere with the backscatter response from the Intellitag 500 tag. This creates
Intellitag® 500 SmartPass® Reader System ModificationsF-4difficulty for the reader in reading the response from the Intellitag 500 tag, or can cause the reader to miss the response from the Intellitag 500 tag altogether.The Intellitag 500 SmartPass Reader system can read either a read-only ATA or ISO type tag, or a Intellitag 500 tag in a given vehicle, but not both simultaneously. If a vehicle is equipped with both tag types, it is probable that the read-only tag will be read; however, it is very possible that the Intellitag 500 tag will not be read, depending on a number of factors. The factors that influence the readability include, but are not limited to, physical orientation and configuration; the type of read-only tag; the ratio of backscatter cross-section of the tags; and whether the tag is battery or beam powered.CommandsNo direct impact on commands.Programmable Attenuation Control AddedModificationReplacing the range control function gives the Intellitag 500 SmartPass Reader a programmable attenuation control for the output radio frequency (RF) power. This feature simplifies the design and streamlines the testing during manufacturing and installation processes. Valid settings for attenuation are in 1.0 dB increments over a range of 10-dB attenuation, from the maximum power setting of 2 watts at 0-dB attenuation to a minimum power level of 200 milliwatts at 10-dB attenuation.CommandsThis modification introduces the following command:644NN Set RF attenuation (new command)Table F-1 lists the Set RF attenuation command variable (NN) and attenuation settings.Table F-1 Set RF Attenuation Command Settings and VariablesVariable (NN) Attenuation Setting (dB)00 001 102 203 304 405 5
Intellitag® 500 SmartPass® Reader System ModificationsF-5FReal-Time Clock, Time/Date Stamping RemovedModificationThe Intellitag 500 SmartPass Reader design eliminates the real-time clock, thereby eliminating all functions associated with setting the time and date. This change reduces the recurring cost of the reader, and might alleviate concerns associated with maintenance, environmental, and shipping issues because the battery is being eliminated. The reader responds to set time and date commands with an error message, except for the Disable time/date append command. For this command, the Intellitag 500 SmartPass Reader responds with Done.CommandsThis modification affects the following commands:20S…S Set time21S…S Set date22 Display time and date 300 Disable time and date append302 Enable time and date append 524 Display appended info status661 Display diagnostics results664 Test real-time clockTag Data Buffering and Storage ReducedModificationThe Intellitag 500 SmartPass Reader does not provide tag memory storage beyond the quantity required for data buffering from the tag to the host. The Intellitag 500 SmartPass Reader responds with an error message to commands associated with this function, except for the Disable buffer control mode when a Done response is returned.06 607 708 809 90A 10Table F-1 Set RF Attenuation Command Settings and Variables

The reader responds with an error message to all commands associated with this function, except for Disable periodic check tag when the reader returns a Done response. Additional alternate diagnostics functions may be investigated for feasibility to integrate into the reader.CommandsThis modification affects the following commands:550 Display periodic check tag status551 Display selected check tag option810 Disable periodic check tag 8110 Invoke check tag8120 Enable periodic check tag8160 Select internal check tagBaud Rates Below 2400 Bits Per Second RemovedModificationThe Intellitag 500 SmartPass Reader design eliminates baud rates below 2400 bits per second. The reader responds with an error message to commands associated with these baud rates.CommandsThis modification affects the following commands:522 Display comm port parameters1000 Set baud rate = 110 baud
Intellitag® 500 SmartPass® Reader System ModificationsF-7F1001 Set baud rate = 300 baud1002 Set baud rate = 1200 baudNo Dual-Frame CapabilityModificationThe Intellitag 500 SmartPass Reader cannot read more than one frame per tag in the ATA read-only mode. The reader responds with an error message to commands associated with this function.CommandsThis modification affects the following commands:48N Select dual-frame processing mode536 Display dual-frame processing modeNo AAR or ATA Tag Data Translation ModeModificationThe Intellitag 500 SmartPass Reader cannot parse and translate the fields defined in the American Association or Railroads (AAR) or ATA specification. The reader responds with an error message to commands associated with this function.CommandsThis modification affects the following commands:452 Disable tag translation mode453 Enable tag translation mode534 Display tag translation modeRange Control RemovedModificationThe Intellitag 500 SmartPass Reader design does not include the range control function. The range control function is replaced by the programmable output RF power control. This simplifies the design and streamlines the testing during manufacturing and installation. For backward compatibility with the AI1620 SmartPass Reader, the Intellitag 500 SmartPass Reader responds to a command for maximum range (1F Hex) with a DONE response.CommandsThis modification affects the following command:643NN Select RF operating range (distance)
Intellitag® 500 SmartPass® Reader System ModificationsF-8Enable Diagnostic RF Continuous Wave Command AddedModificationFor diagnostic and testing purposes, a new additional command lets the user test the system while continuous wave (CW) RF is being transmitted. This command lets the reader transmit a CW RF signal at the output frequency and attenuation level as specified in the associated commands. Output CW RF is sustained until one of the following commands are received by the reader:6400 Turn RF off6401 Turn RF on641 Select RF by input controlThere is no data associated with the Enable diagnostic RF continuous wave command.CommandsThis modification introduces the following command:6402 Enable diagnostic RF continuous wave (new command)
