IT2410 Tag Programmer Hardware
This chapter describes the tag programmer’s hardware components and
requirements.
Components
The IT2410 Tag Programmer components include the programmer, power supply,
interconnecting cables, and anti-static wrist strap. The hardware is designed to operate
with a PC. This section describes the hardware requirements for proper operation of
the IT2410 programmer. This section also includes requirements for ESD protection.
Hardware Requirements
The customer-supplied PC requires the following minimum specifications:
•
PC with Intel Pentium (or equivalent microprocessor) 90 MHz, or higher
•
Microsoft Windows 2000, 98/95, or NT 4.0 with Service Pack 3 or higher
•
32 MB RAM
•
CD-ROM drive
•
Available serial port
•
VGA or high-resolution monitor
•
One 3.5 in. floppy drive, one CD-ROM drive, and a hard drive
•
Mouse or other Windows pointing device
ESD Protection Requirements
If the user does not take proper precautions, ESD damage can occur to the programmer and tags during programming. 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 operating performance. The following are typical symptoms of static discharge:
•
Inability to program the tag
•
Greatly reduced operating range
3-3
IT2410 Tag Programmer User Guide
•
Tag operating failure
Static 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 clothing
ESD Workstation Design
Well-designed workstations use a system of multiple protection elements. At a minimum, this protection should include anti-static bench mats and wrist straps to discharge static safely away from the equipment.
As an additional measure to prevent static damage, keep tags in their original packaging, on an anti-static mat, or within an ESD-inhibiting container until you are ready to
program the tags.
Using the ESD Wrist Strap
Always attach the ESD strap before beginning programming operations. Perform the
following steps:
3-4
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).

Figure 4-2 Power and Serial Interface Connections
Powering Up
When 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.
4-5
IT2410 Tag Programmer User Guide
Programming Cycle
When 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 Cycle
When the verify cycle is initiated by the remote host system, the VERIFY LED illuminates and the alarm beeps each second for an approximate 10-s period or until the verify 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 programmer 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. Table 4-1 lists the various programmer operations and the
corresponding alarms that sound as an audible operation verification.

Frequently Requested Tag Programming
Information
This appendix explains frequently requested information regarding
IT2200-series tag programming information.
Identification, Serial Number, and the Global Password
TransCore 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 hexadecimal 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 specifications.
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. Table C-1 shows the tag page layout.

Changing the Global Password
As 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, safeguard it to prevent unauthorized access to the tag.
Reading and Setting Nonvolatile Status for General
Pages
Note: 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.
C-6
Frequently Requested Tag Programming Information
Perform 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 general frame in question, then that frame is nonvolatile, and a copy is saved in
EEPROM. For example:
Returned data:
D400
Hexadecimal to binary conversion: 1101 0100 0000 0000
MSB
LSB
The most significant bit (MSB) corresponds to general Page 0, and the least significant 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 nonvolatile, 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 information, general Pages 0 and 1 are saved in nonvolatile memory despite the bit settings 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:
Returned data:
c160
Hexadecimal to binary conversion: 1100 0001 0110 0000
MSB
LSB
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.
C-7
IT2410 Tag Programmer User Guide
To 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 Sequences
The 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.

presented in Table C-3.

The 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. Program 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 Feature
The 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 consists 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
C-9
IT2410 Tag Programmer User Guide
hex data, it still will be interpreted as ASCII and the tag will display an unintelligible
message on its LCD.
To discontinue using the custom message, send the tag another GEN ACK command
with 0’s in the LCD message page pointer field.

Application Program Interface

Appendix D
Application Program Interface
This appendix describes the application program interface (API) for the
IT2410 Tag Programmer.
Interface Definitions
Communication 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 protocol (ECP) additions to maintain error-free communications.
Ethernet Communications Conduit
All 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 mask
TransCore recommends that you first configure the Ethernet settings using the standard 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 communications occur using port 8000.
Responses to all command requests are categorized as either synchronous or asynchronous. Some requests have a synchronous response associated with them. Some
requests also have an asynchronous response associated with them. Some asynchronous 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.

characters so that the host computer can detect the beginning and end of each message.
General Software Information
All tag programmer commands are preceded by a start-of-message () ampersand character (&) followed by an end-of-message () percent character (%). All
data after the  character is ignored until the next  is detected.
Any & character that occurs in the message between the  and  is converted to the backslash and at character (\@) sequence. Any % character is converted
to the \? character sequence. All \ characters are converted to the \\ sequence. All
 and  character conversions are performed after the cyclic redundancy
check (CRC) has been performed on the transmit data and before the CRC is performed on the receive data.
Programmer-to-Host Software Communications
Protocol
The programmer and host interface use the following communications protocol for
command responses and asynchronous responses.
D-4
Application Program Interface
Binary-coded integer messages are contained in a protocol defined by:
    []  
where
 - start of message is used to find the start of the next message following a mes-
sage time-out or following the end of the previous message. All data is ignored until
the  is detected. The start of message is defined as the ASCII character &.
 - a combination of  and  makes 16 bits or 2 bytes of data.
The sequence number is 6 bits and the length is 10 bits. The sequence number is used
for the error detection scheme. The value for sequence number may represent any
number between 0 and 63 with the following restrictions:
•
The sequence number for command responses matches the sequence number of
the last received command.
•
The sequence numbers for asynchronous messages are 0,2,4,6,...,62 and is incremented after each new asynchronous message.
 - length is a group of 10 binary bits that specifies the number of bytes in the
response and data fields.
 - response is 2 bytes long to indicate the status of the command received by
the programmer from the host. Responses are described in Table D-2.

Ethernet Asynchronous Command and Response
Protocol
Tag data or diagnostics data generate asynchronous or command responses. Asynchronous 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 command responses and asynchronous responses shown here. Binary-coded integer messages contained in a protocol are defined by:
  []
where
 - length specifies the number of bytes in the response and data fields. The
range for this field is 2 to 1022.
 - response is one-word long to indicate the status of the command received by
the host from the reader. The responses are shown in Table D-4.

Serial Error Detection and Recovery for the Programmer
Rather 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 communications 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 Failures
Serial data transmission failures can occur in one the three forms:
D-8
•
Modified byte
•
Extra byte
•
Lost byte
Application Program Interface
Modified bytes are detected by the CRC check. Extra bytes are detected by the CRC
and are compensated for by the  and . Lost bytes require that time-outs
be implemented to prevent lockups caused by anticipation of additional bytes being
received as specified by the . The time-outs implemented are described as follows:
•
Any received  ...  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  ... ACK ...  should take less than 1.0 s.
•
A command  ... response ...  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.
D-9
IT2410 Tag Programmer User Guide
Serial Sequence Numbers
The host maintains control of the sequence numbers for commands and their associated 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 maintained 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 Responses
Tag 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 List
The 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 commands are further divided according to their functionality, for example, communications and real-time clock.

Restore Programmer Configuration
The Restore Programmer Configuration command is used to return the programmer to
its original factory default settings. 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 D7. This data defines the source (factory defaults or NVM) of the configuration parameters of the programmer. The NVRAM parameters are the last saved using the Set Programmer Configuration command. Upon command, the programmer changes the
programmer configuration to the values from the selected source immediately following the transmission of the command response (Table D-8).

Get/Set Programmer Security Characters
Unique security characters are programmed into each customer tag programmer at the
time of manufacture and are assigned and tracked by TransCore. Each security character 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

Get/Set Programmer Serial Number
The Get Programmer Serial Number command requests the factory-programmed
serial number. The Set Programmer Serial Number command sets the programmer
serial number.
Programmer serial numbers are individually programmed into each programmer at the
time of manufacture. Serial numbers are related to a set of security characters that
have been assigned to the programmer. Serial numbers are identified in the unique
released document for each customer programmer.
The data associated with the get/set programmer serial number commands is shown in
Table D-14.

Get/Set Programmer Control
The Get Programmer Control command requests the tag command time-out and programmer audio buzzer settings. The Set Programmer Control command enables or
disables the programmer control of the tag time-out and audio buzzer.
The tag command time-out instructs the programmer to continue sending a tag command (read, write) over the RF link for a specified period of time. These values are
stored in the programmer’s NVM. The data associated with the Get/Set Programmer
Control commands is shown in Table D-15.

of 0 to 255. A value of 0 represents a time-out of 100 ms. A value of 255 represents a
time-out of 25.6 s. This tag command time-out determines the length of time that the
programmer continues to send tag commands over the RF link after having received
the tag command request from the host. The factory default value for the tag command
time-out is 10 s.
Buzzer disable — This bit is used to control the status of the audible indicator for the
programmer. When set to 1, the buzzer functions for the programmer are disabled. The
factory default for the buzzer disable is 0, or buzzer enabled.
Set Programmer Password
The Set Programmer Password command sets and verifies the user password. The user
password can only be changed by resending the set programmer password command
within two seconds of password verification.
Note: Any host software should prompt the user to reenter, or verify, the new password prior to sending a change to the programmer.
These commands are applicable to the programmer only. This command is not linked
with a get command. This maintains the integrity of the password.
The programmer maintains the current user password in NVM that is supplied by the
host. The programmer only responds to a limited command set until the password supplied by the host matches the one stored in NVM. The user password is used to initiate
a programming session. The data associated to the set programmer password command is provided in Table D-16.

password is activated.
A backdoor password is available from the factory for customers who lose or forget
their password. The backdoor password is only valid for a limited period of time. Perform an update of the programmer password after use of this backdoor password so

Programmer Command Restrictions
This section describes the interaction of commands and functions.
During manufacturing of the programmer, the security characters, Ethernet parameters, and serial number are set. The security characters, MAC address, and serial number are written to the programmer and can only be changed at the factory.
Each time the programmer is powered on it performs a self-test and awaits an
acknowledgement from the host. Only the select commands are valid until the Set
Time/Date command is issued. Further restrictions apply until the programmer password is verified using the Set Programmer Password command.
The Identify, Reset Programmer, and Get/Set Time/Date commands are always available regardless of password status. The Set Programmer Password command is only
available after the time and date have been set and validated. The Set Serial Number
and Set Security Characters commands are available only to the factory. Limited tag
commands are available until the programmer password has been verified. Virtually
all commands are available once the programmer password has been verified.
Figure D-1 illustrates the precedence of these functions. The Time/Date is set in permanent programmer memory. Once set and saved using Save Programmer Configuration, the Time/Date no longer need to be set.

Get/Set Communications Baud Rate
The Get Communications Baud Rate command requests programmer’s communications baud rate. The Set Communications Baud Rate command sets the programmer

Upon command, the programmer changes its baud rate to the selected value immediately following the transmission of the command response. It is recommended that the
baud rate only be changed on the host after the programmer has received the acknowledge so that communications are maintained.
Note: You might want to have a command in the host to let the user change the baud
rate when the programmer has been saved to a different baud rate than that of the host

If a fault message occurs, a bit representing the fault is set in the diagnostic report
data. The status codes associated with the diagnostic reports are as follows:
•
The command code at powerup or after the issue of a reset command for the diagnostic report status code is 8000H.
•
The command code for background diagnostic report status code is 8001H.
The data associated with the power-on and background status reports for the programmer is specified in Table D-27.

Valid Response Tag Data
Valid response tag data is reported asynchronously when a tag is detected. The status
codes associated with the tag data reports are shown in Table D-29.

When a tag is detected, tag data is sent to the host computer or lane controller. If it
passes the CRC check, the tag data is assumed to not be corrupted.
