The IT2410 programmer has an external banana plug socket that provides a point of attachment for the ESD wrist strap included with the tag programmer.Static discharge may cause significant damage that can adversely affect a tag’s operat-ing performance. The following are typical symptoms of static discharge:•Inability to program the tag•Greatly reduced operating range

IT2410 Tag Programmer User Guide3-4•Tag operating failureStatic is generated by friction and can often build to damaging levels. The following are some of the causes of static:•Shoes moving across a carpeted or plastic floor•Hot air blowing into a room from a hot-air duct•Rubbing tags together•Sliding tags across a table top•Friction created while wearing certain types of clothingESD Workstation DesignWell-designed workstations use a system of multiple protection elements. At a mini-mum, this protection should include anti-static bench mats and wrist straps to dis-charge static safely away from the equipment.As an additional measure to prevent static damage, keep tags in their original packag-ing, on an anti-static mat, or within an ESD-inhibiting container until you are ready to program the tags.Using the ESD Wrist StrapAlways attach the ESD strap before beginning programming operations. Perform the following steps:1. Place the strap on the wrist and snap the ESD strap to the elastic wristband.2. Connect the banana plug (see Figure 2-3 on page 2-6) on the ESD wrist strap to the ESD banana socket on the front of the tag programmer (see Figure 2-3 on page 2-6).

Connect the ESD wrist band banana plug to the socket on the tag programmer’s front panel.Figure 4-2 shows the location of the power and serial interface connectors on the tag programmer’s back panel.Figure 4-2 Power and Serial Interface ConnectionsPowering UpWhen all the equipment is connected as described in the preceding section, apply power to the system components as follows:1. Switch on the PC and verify its proper operation.Note: Do not place a tag in the programmer head at this time. The indicator lights operate differently when a tag is already in place.2. Switch on the tag programmer’s power switch located on the programmer’s rear panel. The green POWER LED illuminates.Note: The operating system will initiate a self-test upon power up or after power interruption.When the tag programmer’s internal power-on self-test is successfully completed, the user is notified as follows:•The green READY indicator light illuminates.•After approximately 10 seconds, the tag programmer sounds three short tones in rapid succession.If the tag programmer fails to power up, the READY LED goes out, and the ERROR LED illuminates and the alarm beeps once for one second.The IT2410 unit is now ready to start programming tags.

IT2410 Tag Programmer User Guide4-6Programming CycleWhen the programming cycle is initiated by the remote host system, the PROGRAM LED illuminates and the alarm beeps for an approximate duration of 0.25 seconds, once a second, for a 10-s period, or until the programming operation has completed.The operator has an approximate 10-s time-out period in which to place an operating IT2200-series tag on the programming head fixture. Once the tag is in the fixture and the programmer detects the valid RF data, the programmer executes the specific write command from the host.If the programming is successful then the PROGRAM LED goes out and the alarm sounds three times for approximately 0.25 seconds each.If the programming cycle is unsuccessful or a tag is not detected within the 10-s period, the ERROR LED illuminates and the alarm sounds once for approximately 1 second.Verifying CycleWhen the verify cycle is initiated by the remote host system, the VERIFY LED illumi-nates and the alarm beeps each second for an approximate 10-s period or until the ver-ify operation is complete.The operator has a 10-s time-out period in which to place an operating IT2200-series tag on the programming head. Once the tag is placed in the fixture and the program-mer can detect the valid RF data, the programmer executes the specific read command from the host.If the verifying is successful the VERIFY LED goes out and the alarm sounds three short beeps.If the verifying cycle is unsuccessful or if a tag is not detected within the 10-s period, the ERROR LED illuminates and the alarm beeps for 1 second.The tag programmer incorporates an audible indicator that is controlled by software. The indicator’s sound is pleasing to the ear (2200 Hz) and can be easily heard while operating near the unit under normal conditions. The alarm audibly indicates the status of programmer operations.

CFrequently Requested Tag Programming Information

Frequently Requested Tag Programming InformationC-3Appendix CFrequently Requested Tag Programming InformationThis appendix explains frequently requested information regarding IT2200-series tag programming information.Identification, Serial Number, and the Global PasswordTransCore documentation and/or host software references a tag identification number (ID) that corresponds to the Title 21 ID. The Title 21 ID is a unique identifier used by radio frequency identification systems in California. This is found in the first 8 hexa-decimal characters (32 bits) of the tag’s general Page 1. In all IT2200-series tags, this ID is either the same as the serial number from Page 0, or other application specifica-tions.The tag serial number (S/N) is the first 8 hexadecimal characters (32 bits) in general Page 0. The global password is 64 bits long and the default is generated by repeating the serial number twice. Once this global password is known, it can be used to change read and write passwords on any of the general pages of data in the tag, change which frames are designated nonvolatile, and lock pages of data so that they cannot be changed unless the page is unlocked first using the global password.These two identifying numbers are in addition to any customer-specific ID numbers. Most of the customers that use the IT2200-series tags employ one of the other general pages of data available in the tag to store their own unique ID number, which usually corresponds to a patron account number.The global password in the IT2200-series tag acts like a master key, which can be used to perform crucial tag operations and is meant to be controlled by the owner agency. It has a default setting that is created from the tag’s unique serial number, but can be changed by the owner agency, if desired.

IT2410 Tag Programmer User GuideC-6Note: * These commands are write only.Changing the Global PasswordAs with personal identification numbers, or PINs, which are used with automatic teller machines, the first time that a tag’s global password is changed, it is from the default setting. You must know the tag’s current global password before you can change it. To change it, you must execute a write request to owner Page 4. The host program that is being used to communicate with the reader should prompt you for the current global password as well as the new password. Once you change the global password, safe-guard it to prevent unauthorized access to the tag.Reading and Setting Nonvolatile Status for General PagesNote: It is important to make any critical information in the tag nonvolatile, or the information is lost when the tag batteries run down, or are changed. To find out which general pages of data have been set to nonvolatile status, read owner Page 3 by using the global password. *001FH Write User Password for Page 000BH User 4*0020H Write User Password for Page 000CH User 4*0021H Write User Password for Page 000DH User 4*0022H Write User Password for Page 000EH User 4*0023H Write User Password for Page 000FH User 4*0000H Page lock bits Owner 2*0001H Reserved for Read Password lock Owner 2*0002H Reserved for Write Password lock Owner 2*0003H Page NV RAM bits Owner 2*0004H Global Password Owner 8Table C-1 Tag Page Layout (continued)Page Number (in HEX) Field Name Area Length in Bytes

Frequently Requested Tag Programming InformationC-7Perform a read request of owner Page 3 and enter the global password when you are prompted for it. The read response should return 4 hex characters (16 bits) of data, each bit corresponding to a general page of data. If the data bit is a logic 1 for the gen-eral frame in question, then that frame is nonvolatile, and a copy is saved in EEPROM. For example:The most significant bit (MSB) corresponds to general Page 0, and the least signifi-cant bit (LSB) corresponds to general Page 15, so for this example Pages 0,1,3, and 5 are nonvolatile.To change the status of the nonvolatile bits, perform a write request to owner area Page 3 using the global password. Depending on the host program used, the write data is entered in hexadecimal form. For example, to make only frames 3, 4, and 12 non-volatile, the write data is entered as 1808 hex. This translates to the following binary data: 0001 1000 0000 1000.Note: To preserve factory configuration data and built-in-self-test diagnostic infor-mation, general Pages 0 and 1 are saved in nonvolatile memory despite the bit set-tings in owner Page 3.Locking Frames (Page Locks)The page lock feature is used to designate general pages as read only. Once a page is locked, the global password must be used to unlock it before a successful write request can be processed to change the data in that frame. The page lock bits are stored in owner area Page 0.To read the page lock bits, execute a read request of owner Page 0 and enter the global password when the host program prompts you for it. The read response should return 4 hex characters (16 bits) of data, in which each bit corresponds to a general page of data. If the data bit is a logic 1 for the general frame in question, then that frame is locked and is read only. For example:The MSB corresponds to general Page 0, and the LSB corresponds to general Page 15. In this example Pages 0,1,7,9, and 10 are locked.Returned data: D400Hexadecimal to binary conversion: 1101 0100 0000 0000MSB LSBReturned data: c160Hexadecimal to binary conversion: 1100 0001 0110 0000MSB LSB

IT2410 Tag Programmer User GuideC-8To change the status of the nonvolatile bits, use the global password to perform a write request to owner area Page 0. Depending on the host program used, the write data is entered in hexadecimal form. So for example, to lock frames 4 and 7, the write data is entered as 0900 hex. This translates to binary data as follows: 0000 1001 0000 0000.Auto Beep on Acknowledge and Read SequencesThe IT2235 Tag features an Auto Beep function. This lets the tag emit various beep sequences after receiving either a Title 21 acknowledge (ACK) command or a Title 21 Read Request. A byte, called the mode bits, programmed into general Page 0 controls this function. The mode bits are detailed in Table C-2.The EEPROM configuration mode bit is for factory use only. When setting the Auto Beep function, always make this bit a logic 0.The other bits in this byte all apply to the Auto Beep function. The Auto Beep A/V bits 4 through 0 can be set to emit the desired A/V sequence based on the information presented in Table C-3.

Frequently Requested Tag Programming InformationC-9The Auto Beep on ACK bit, when set to 1, enables the automatic initiation of the encoded A/V sequence determined in Auto Beep A/V code bits 0 to 4 after a Title 21 ACK is processed.The Auto Beep on read bit, when set to 1, enables the automatic initiation of the encoded A/V sequence determined in Auto Beep A/V code bits 0 to 4 after a Title 21 read request has been processed, and the tag enters an idle state.For example, if you want the tag to beep three times with a HI tone whenever it receives a Title 21 read, program the byte to a value of 01001101, or a hex 4D. Pro-gram general Page 0 with this byte, and the following sequence must occur:1. Read the page lock bits (owner Page 0), note their values for later restoration.2. Write to owner Page 0 to change the lock bit for general Page 0 to a value of 0. 3. Write to general Page 0, changing only the mode bits field to the value desired (hex 4D in the example on page C-7). 4. Write to owner Page 0 to change the lock bit for general Page 0 to a value of 1. Using the Custom Message FeatureThe IT2235 Tag can store a custom message of up to 16 ASCII characters, and display the message on the LCD when the tag pushbutton is pressed. To use this capability, program the custom message into one of the general data pages (Pages 2 to 15), and then send a GEN ACK command with a pointer indicating where the custom message is stored in tag memory. The GEN ACK command has a field called the LCD message page pointer that con-sists of 1 byte (8 bits). If the custom message, for example, is stored in general Page 5, this page pointer in the GEN ACK command is set to a value of 00000101 binary, or 05 hex.The LCD controller always interprets the data as ASCII data. Therefore, if a GEN ACK command is sent that points to a custom message page and the page has normal 0101 1HI-LO-HI-LO0111 1LO-LO-LO1001 1HI-HI-HI1011 1HI-HI1101 1Long HI1110 1LO1111 0HI1111 1HITable C-3 A/V Options Bits Decoding (continued)

Application Program InterfaceD-3Appendix DApplication Program InterfaceThis appendix describes the application program interface (API) for the IT2410 Tag Programmer.Interface DefinitionsCommunication between the tag programmer and host occurs via a serial RS–232 interface or an Ethernet (TCP/IP) interface. “Ethernet Communications Conduit” describes the TCP/IP interface. “Communications Protocols” on page D-4 describes the serial protocol. This platform performs data transfer, commands, and responses in a binary-coded format similar to the ISA data structure, but with error correcting pro-tocol (ECP) additions to maintain error-free communications.Ethernet Communications ConduitAll Ethernet parameters are factory set initially and will need to be reset to the correct customer configuration in the field to function properly. All parameters except the media access control (MAC) address can be changed in the field. These parameters are factory defaults:•MAC address•Programmer IP address•Host IP address•Gateway IP address•Network maskTransCore recommends that you first configure the Ethernet settings using the stan-dard RS–232 communications conduit. Subsequent changes can be made using either the RS–232 or Ethernet conduits. Changes to Ethernet settings will not take effect until after the unit has been reset either by command or by switching the power off and on.The IT2410 Tag Programmer operates as a TCP/IP client. The programmer attempts to connect to a listening socket server (also known as host). The Ethernet communica-tions occur using port 8000.Responses to all command requests are categorized as either synchronous or asyn-chronous. Some requests have a synchronous response associated with them. Some requests also have an asynchronous response associated with them. Some asynchro-nous responses occur independent of any request by the application. Some of these responses contain data, the content and format of which is included with the definition of each command.

$IT2410 Tag Programmer User GuideD-4RS–232 Communications ConduitThe RS–232 conduit is configured with the defined communications parameters listed in Table D-1.Table D-1 Communications ParametersCommunications ProtocolsTransCore reader systems use a programmer-to-host software protocol. The protocol information that is presented in this section provides reference information relevant to developing host software.Each message is framed with the start-of-message (som) and end-of-message (eom) characters so that the host computer can detect the beginning and end of each mes-sage.General Software InformationAll tag programmer commands are preceded by a start-of-message (<som>) amper-sand character (&) followed by an end-of-message (<eom>) percent character (%). All data after the <eom> character is ignored until the next <som> is detected.Any & character that occurs in the message between the <som> and <eom> is con-verted to the backslash and at character (\@) sequence. Any % character is converted to the \? character sequence. All \ characters are converted to the \\ sequence. All <som> and <eom> character conversions are performed after the cyclic redundancy check (CRC) has been performed on the transmit data and before the CRC is per-formed on the receive data.Programmer-to-Host Software Communications ProtocolThe programmer and host interface use the following communications protocol for command responses and asynchronous responses.Parameter ValueBaud 19,200 or 38,400 (factory default)Data bits 8Parity NoneStop bits 1Software flow control NoneHardware flow control None$

Asyn-chronous responses have no associated commands. An interrupt occurs notifying the lane controller or host computer of a response to read data from the first-in-first-out (FIFO) data I/O address if interrupt mode is enabled. Otherwise, polling the FIFO buffer status register notifies the lane controller or host computer to asynchronous responses. The reader and host interface use the communications protocol for com-mand responses and asynchronous responses shown here. Binary-coded integer mes-sages contained in a protocol are defined by:<len> <resp> [<data>]where<len> - length specifies the number of bytes in the response and data fields. The range for this field is 2 to 1022.<resp> - response is one-word long to indicate the status of the command received by the host from the reader.

See the “Command List” on page D-10 for more information.Serial Error Detection and Recovery for the ProgrammerRather than implementing a complex ECP, the IT2410 Tag Programmer uses a method of error detection and recovery, which consists of a combination of CRC, sequence numbers, a simple structured protocol with message delimiters, a message length, and message time-outs. By using this combination of error detection and structured com-munications protocol, a high-level of confidence is obtained without the overhead associated with standard ECP.These methods are described in the following sections.Serial Message FailuresSerial data transmission failures can occur in one the three forms:•Modified byte•Extra byte•Lost byte Response Meaning0000H Command complete0001H Command in progress0002H Command data invalid0003H Command invalid0004H Command aborted3XXXH Valid read tag data3000H No-tag data status code3001H IT2200 Read/write tag data status code3002H Reserved8XXXH Diagnostic data8000H Power-up diagnostic report status code8001H Background diagnostic report status code8002H Download activeAXXXH Diagnostics statistical data

Application Program InterfaceD-9Modified bytes are detected by the CRC check. Extra bytes are detected by the CRC and are compensated for by the <som> and <eom>. Lost bytes require that time-outs be implemented to prevent lockups caused by anticipation of additional bytes being received as specified by the <len>. The time-outs implemented are described as fol-lows:•Any received <som> ... <eom> should take less than 500 ms. This assumes 1500 characters at 19.2 k baud and long commands are followed by short responses.•The asynchronous data <som> ... ACK ... <eom> should take less than 1.0 s.•A command <som> ... response ... <eom> may take considerably longer because of command processing time.If a message CRC or time-out error occurs during the command/response message sequence, the error reporting will occur as follows.•For a CRC failure that occurs during the command message, the programmer reports the error to the host using the NACK message.•For a CRC failure or time-out failure that occurs during the response message, the host reports the error to the programmer by retransmitting the command message.If a message CRC or time-out error occurs during an asynchronous response/ACK message sequence, the error reporting will occur as follows:•For a CRC failure that occurs during the asynchronous response message, the host should report the error to the programmer using the NACK message.•For a CRC failure or time-out failure that occurs during the ACK message, the programmer reports the error to the host by retransmitting the asynchronous response message.

IT2410 Tag Programmer User GuideD-10Serial Sequence NumbersThe host maintains control of the sequence numbers for commands and their associ-ated responses. •A command is not complete until a response with a proper sequence number is received from the programmer. •A response is not complete until the host changes the command sequence number from the previous command. If the command sequence number does not change, the response is retransmitted by the programmer.Sequence numbers for asynchronous response communications sequences are main-tained by the programmer. •An asynchronous response transmission sequence is not complete until an ACK is received from the host with a proper sequence number. •An ACK is not complete until the programmer changes the data sequence number. If the data sequence number does not change, the ACK is retransmitted by the host.To prevent asynchronous messages from being interpreted as command responses when host and programmer sequence numbers pass each other, the host sequence numbers should be odd (1,3,5,7,...,63) and programmer sequence numbers should be even (0,2,4,6,...,62).Serial Asynchronous ResponsesTag data or diagnostics data will generate asynchronous responses, that is, responses that have no associated commands. If the host begins sending a command during this time, the host ignores the asynchronous response. The programmer automatically retransmits the asynchronous response following the command execution.Command ListThe command list (Table D-5) describes the command requests that are used between the programmer and the host computer and/or lane controller. Within the list, the com-mands are further divided according to their functionality, for example, communica-tions and real-time clock.

The Restore Programmer Configuration command requests the programmer to reconfigure its current internal settings (RF frequency, RF attenuation, etc.) to what is saved in nonvolatile memory or to default factory settings.The data associated with the Restore Programmer Configuration is shown in Table D-7. This data defines the source (factory defaults or NVM) of the configuration param-eters of the programmer. The NVRAM parameters are the last saved using the Set Pro-grammer Configuration command. Upon command, the programmer changes the programmer configuration to the values from the selected source immediately follow-ing the transmission of the command response (Table D-8).Table D-7 Programmer Configuration DataBits 7 - 1 Bit 0Spare Programmer configuration control

All buffered tag responses will be deleted after execution of this com-mand. Execution time is approximately 10 s.Reset Control — This field contains a unique value to prevent a bit error from inad-vertently causing a soft reset of the programmer. This field must contain the hexadeci-mal value A5A5 to invoke a reset of the programmer.Save Programmer ConfigurationThe Save Programmer Configuration command causes the current configuration of the programmer to be saved to NVM. There is no data associated with the Save Pro-grammer Configuration command. See the “Restore Programmer Configuration” on page D-13 for a listing of the parameters that are saved and the factory default values for each.Get/Set Programmer Security CharactersUnique security characters are programmed into each customer tag programmer at the time of manufacture and are assigned and tracked by TransCore. Each security charac-ter set is linked to a programmer serial number, also assigned and managed by TransCore. The security codes are programmed at the factory prior to shipment.The Get Programmer Security Character command requests the programmer’s assigned security characters. Security characters are bit patterns in predetermined positions in the American Trucking Association page. The Set Programmer Security Character command sets the programmer security characters.Invalid security characters are reported using command data invalid response code as specified in the “Ethernet Asynchronous Command and Response Protocol” on page D-7.The data associated with the Get/Set Programmer Security Characters command is shown in Table D-11.Table D-11 Security Characters DataSecurity character — This field contains a two-byte quantity indicating that the security characters are assigned to the programmer. These security characters may be used to aid in controlling fraudulent use of any reader system.
