Installation9Reader Mechanical InstallationThe MP9311 is designed for installation within an enclosure. The housing is provided with four M4 clearance through-holes for module mounting. The reader dimensions are shown in Figure 8.Caution Prior to mounting the reader in an enclosure, you must evaluate the operating conditions and resulting thermal profile. When operated at maximum RF power and input supply voltage, the MP9311 can dissipate as much as 11W of power. As a result, any enclosure design must dissipate the generated thermal energy and maintain the internal reader temperature below +85 degrees C. Mounting the bottom surface of the reader in direct contact with a metal plate will provide the most efficient method of dissipating heat.

Installation11Installing the RF Command Suite ApplicationThe SAMSys RF Command Suite is a Microsoft Windows application that provides a Graphical User Interface (GUI) for SAMSys RFID Reader Products. The application allows you to easily view tag data, configure the reader, and perform other tag data functions. In addition, the RF Command Suite is the preferred method for sending CHUMP commands to a reader. The RF Command Suite application is provided on the CD shipped with your reader and can be installed on a personal computer. To install RF Command Suite, refer to Chapter 1 - Introduction in the RF Command Suite User’s Guide.
MP9311 User’s Guide12Setting Transmit Power - TD0Output power on the MP9311 is set by configuring the Transmit Power (TD0) register. The output power is entered in tenths (1/10) of dBm with steps of 1/10 dBm. All values are in decimal. For example, entering a value of 121 equates to 12.1 dBm.For example, to set the MP9311 output power to 17.5 dBm, issue the following CHUMP command to the reader:}Cw,d:TD0,b:175!The valid range of values for TD0 is from 0 (0 dBm) to 280 (28 dBm).Setting Antenna Gain - TG0 (MP9311-Wxx only)In order to comply with ERP and threshold limits according to EN 302 208, MP9311-Wxx models must be configured with the proper antenna gain. Antenna gain is set by the TG0 register. Before operation, you must determine the actual antenna gain used in the installation, GA.To program the TG0 register, issue the following CHUMP command to the reader:}Cw,d:TG0,b:xxx,f:1! Where:xxx is computed as follows: xxx = (GA (db) + 13.0) * 10 The range of allowable xxx is 000 through 230 which gives an allowable antenna gain range of -13dB to +10dB. Proper LBT operation according to EN 302 208 is not guaranteed with antennas outside of this range.
Installation13Selecting ETSI Frequency Bands (MP9311-Wxx only)Single Frequency SelectionMP9311-Wxx readers can be configured to operate in one of the following ETSI single frequency bands (as defined in ERC/REC 70-03 and EN302-220).• Annex 1 Band I - 869.525 MHz• Annex 1 Band k - 869.850 MHz.These bands are selected by setting Bits 28 and 29 of the 32-bit Transmit Power Configuration (TPC) register. For additional information on TPC register bit settings, refer to Figure 11.To select Band I - 869.525 MHz, issue the following command to the reader:}Cw,d:TPC,b:00000000!,f:1!To select Band k - 869.850 MHz, issue the following command to the reader:}Cw,d:TPC,b:10000000!.f:1!Frequency Hopping SelectionIn addition, MP9311-Wxx model readers can be configured to operate in the ETSI frequency hopping band (as defined in EN 302-208).To select EN 302-208 operation, issue the following command to the reader:}Cw,d:TPC,b:00040000!,f:1!

This mode is equivalent to mode selected by the Auto Read function key on the RF Command Suite Command interface window. If desired, you can reconfigure the reader for Polled RF mode (reader activates the transmit carrier and waits for host to send a read command). Select the Polled Read function key to activate Polled RF mode.To halt the Auto Read or Polled Read mode, press the RF Off function key.Selecting Tag ProtocolsThe MP9311 is factory configured with only those protocols selected by the user. Once protocols are activated, the Command tab function keys can be used to select the protocol. These function keys are programmed with specific command sequences required by the reader to select a particular protocol. To select a specific protocol, perform the following:1. Select the Command interface window.2. Select Function Set 2 or 3 and locate the required protocol.3. Press the function key to select the protocol.4. To view the command sequence performed by this function, hold the mouse pointer over the key or right click while holding the mouse pointer over the key and select Edit Macro.5. Do not change the command sequnce unless you are experienced using SAMSys CHUMP commands to configure readers.

Select the Command interface and then select the radio button for Function Set 2 or 3.9. After locating the protocol on the function key, press the key to activate the protocol.10. The MP9311 is now ready to begin reading tags.External Triggered Tag Inventory OperationIn many applications, the MP9311 can be triggered by an external device such as a proximity switch or optical sensor. In these cases, the MP9311 can be configured to generate tag inventory operations (Rd) for as long as Digital Input 0 (DIN0) is asserted. Digital Output 0 (DOUT0) can also be set to indicate that a successful tag inventory operation was performed.NOTE: The tag inventory operation performs a process called singulation on the tag population and obtains the tag ID for those tags in the RF field.Reader SetupTo setup the reader for external trigger, several MP9311 configuration registers must be modified. Perform the following to setup the reader for external trigger:1. Verify you have RF Command Suite installed on your PC.2. Start up RF Command Suite and select the Command interface tab.3. Press the Auto Read function key (Function Set 1).4. Place a tag in the RF field and verify the tag data is displayed on the Tag Summary interface.5. Next, set the Protocol Configuration Word (PCW) to enable triggered reads on Digital Input 0 and output a read verification on Digital Output 0 (this is equivalent to setting the PCW to 0x2200).6. On the Reader Config interface tab, select:Reader Configuration D General Configuration D Operating Mode D Protocol Configuration Word (PCW) D Digital ...7. Set Digital output 0 (DOUT0) pulse on tag activity to Enable.
MP9311 User’s Guide208. Set Digital input 0 (DIN0) gates auto read action to Enable.9. Finally, set the duration of the output pulse. On the Reader Config interface tab, select:Reader Configuration D General Configuration D Operating Mode D Protocol Digital I/O Control10. Enter a value in milliseconds.11. Press Send Changes to Reader to reconfigure the reader with the news settings.Connecting the External Trigger Circuit12. As shown in Figure 14, apply +5 Vdc to DIN0+ (Pin 8) on SCON1.13. To trigger a read, pull DIN0- (pin 5) Low (0 Vdc or ground) for at least 50 milliseconds. Figure 14–Typical Digital Input Trigger Circuit14. When a tag is singulated, DOUT0 goes high for the duration set by the PIO register.NOTE: When a tag is read, DOUT0 is asserted and stays asserted as long as tag activity continues. The pulse duration calculation is reset with each valid read. Therefore, if the pulse is still in process and a read operation is performed, the pulse will be extended by the value contained in PIO. This logic guarantees a pulse of a specific duration since the last read that occurred+5 VdcExternal Trigger(hold for 50 mSec)4.7K+5 VdcDIN0-DIN0+DOUT0121920

31 Appendix ATag ProgrammingThis appendix describes how to program tags of varying protocols using CHUMP commands sent from a terminal or console. Information provided in this appendix includes the following:• Overview of the Tag Writing Command• Programming the EPC1 Tag• Programming the ISO 18000-6A Tag• Programming the ISO 18000-6B Tag• Programming the Impinj EPC0 Tag• Programming the Matrics Class 0+ Tag• Programming the EPC1, Generation 2 Tag
MP9311 User’s Guide32Overview of the Tag Writing CommandsTag writing with SAMSys readers is performed using the Write Any (Wa), Write Tag (Wt), and Write Verify (Wv) commands Wa must be used when writing to blank tags. Wt is used when the tag already has a tag ID. Wv is a multifunction command that performs any erase, write, and verification needed to program a tag in a specific protocol. This command can also lock the data. A general guideline for using each write command is as follows:Wa is used whenever the write operation affects the tag ID. Wa can also be used for write operations to any data on a tag. This command is executed with a single tag in the RF field.Wt can only be used for write operations to a specific tag where the tag ID has already been assigned. This command can be used for write operations to any data on the tag, except the tag ID itself.Wv can be used for most protocols. However, it is typically used for EPC protocols that require multiple actions such as erasing the tag prior to writing and then locking the data.Some tags support the ability to have a portion or all of their internal memory locked against further modification. Write operations to locked memory will not be successful. The locked status of a piece of memory can be queried via the Yl command. The Yl response is f:0 for unlocked or f:1 for locked.Details of the syntax for any command found in this document can be obtained in the CHUMP Reference Guide.
Tag Programming33Programming the EPC1 TagSAMSys UHF readers can be used to program 64-bit and 96-bit EPC1 tags.Both the Wa and Wv command can be used with the EPC1 (Alien) tags. The Wv command is discussed at the end of this section.Do not use Wt since the tag does not support singulated write operations. Prior to writing, EPC1 tags must be erased. The Wv command and the Wa with the f:3 option will perform the erase action during command execution. If the command specified does not erase the tag during the command execution, then specify the erase operation separately using the Tag Erase (Te) command. Also, in order to calculate the CRC, the entire tag ID must be presented to the reader in one command. EPC1 tags contain an internal CRC value which covers the EPC ID and the kill passcode. The reader always calculates the CRC and writes the correct value to the tag during the write operation. As a result, the entire tag ID and passcode must be presented to the reader in one command. The last byte of the blk data passed in the Wa command is the kill passcode. In the examples that follow, this passcode is set to 00.The format of the Wa command is as follows:}Wa,a:<blk addr>,b:<blk data>[,l:<# blks>][,f:<control flag>]!where:a:<blk addr>. This parameter is optional since there is only a single writeable piece of memory. If specified, the parameter should use block address 0x00.l:<# blks>. This parameter reflects the number of bytes being written and should be equal to 9 if writing a 64-bit EPC ID with the kill passcode or equal to d if writing a 96-bit EPC ID with the kill passcode. If you are not specifying the kill code, the values should be 8 and C, respectively.b:<blk data>. This parameter must contain the entire EPC ID (64- or 96-bit), followed by the one byte kill passcode.f:<control flag>. This parameter controls operations related to writing a tag. Set f:1 to verify the data in the tag following the write operation. Set f:2 to erase the data prior to the write operation. For most applications, set both of these bits with f:3.The following is a typical command to write a 96-bit EPC1 ID tag:}wa,a:0,b:80020304050607090a0b0c0e00,l:d,f:3!The following is a typical command to write a 64-bit EPC1 ID tag:}wa,a:0,b:800080042504600200,l:9,f:3!
MP9311 User’s Guide34In addition to the Wa, Te, and Tr commands, SAMSys readers also support the following EPC1 operations:•Lb Lock Block•Yl Query Lock Status (returns f:0 for unlocked or f:1 for locked)•Td Tag DestroyThe Lock Block and Query Lock Status operations can only be performed with a single tag in the RF field and do not require any parameters. The Tag Destroy operation requires the b: parameter to specify the particular kill passcode for this tag. For detailed information on these and other tag commands, refer to the Comprehensive Heuristic Unified Messaging Protocol (CHUMP) Reference Guide.Using the Wv CommandThe Wv command is a multifunction command that performs any erase, write, and verification needed to program a tag in a specific protocol. The command can also lock the data.The format of the Wv command is as follows:}Wv,b:<EPC data>,m:<lock mask>,k:<kill code>where:b:<EPC data> is the EPC ID to write to the tag.k:<kill code> is the kill code to be written to the reader.m:<lock mask> is the lock mask to indicate which tag field to lock. Each 4-bit nibble in the mask indicates the lock state to apply to a specific part of the tag. A mask nibble value of 1 locks the specific part of the tag. A mask nibble value of 0 indicates no lock is applied.For the EPC1 protocol, the mask nibbles apply to the following fields:To write an EPC ID value of 332233445566778899aabbcc and verify the write, enter:}wv,b:332233445566778899aabbcc!To write the EPC ID data and lock the data, enter:}wv,b:332233445566778899aabbcc,m:1!Mask Nibble 43210Tag Field Unused Unused Unused Kill code EPC data
Tag Programming35Programming the ISO18000-6A TagBoth the Wa and Wt command can be used with the ISO18000-6A tag. In addition to Wa and Wt, two additional commands can modify specific data in the tag. The Wd command modifies the DSFID and Wf modifies the AFI.Typically, the Wt command is used to modify user data in the tag. The Wt, Wd, and Wf commands require the tag ID to be in the d: parameter. Also, the tag must first be put in the SELECT state using the Ts command with the tag ID specified in the d: parameter. NOTE: Some varieties of ISO18000-6A tags are not writeable. Check with your tag vendor to verify if your tag supports write operations.The format of the Wa command is as follows:}Wa,a:<blk addr>,b:<blk data>[,l:<# blks>]!where:a:<blk addr>. In ISO18000-6A, only a single block can be written at one time and this parameter represents the specific four byte block.l:<# blks>. This parameter is optional since each write operation must contain exactly four bytes.b:<blk data>. This parameter must contain four bytes of data.The following is a typical command to write to an ISO18000-6A tag:}wa,a:0,b:01020304!For example, to write AABBCCDD to address 0x20 on a tag with ID E00300001122334455667788, issue the following command:}wt,d:E00300001122334455667788,a:20,b:AABBCCDD!In addition to the Wa, Wt, Wd, and Wf commands, SAMSys readers also support the following EPC1 operations:•Lb Lock Block•Yl Query Lock Status (returns f:0 for unlocked or f:1 for locked)Each of these operations must specify a particular tag ID using the d: parameter or first be put in the SELECT state using the Ts command with tag ID specified in the d: parameter.
MP9311 User’s Guide36Programming the ISO18000-6B TagIn ISO18000-6B, operations are controlled by a state machine within the tag. As a result, the tag must be in the Data Exchange state for the write operation to succeed. To guarantee the tag is in that state, the tag must be reset using the Tag Reset Tr command followed by a Read Detect Rd command prior to performing the first write operation.The ISO18000-6B protocol does not provide any feedback on a global write operation and the reader always provides an Ack ({A) after the tag receives a Wa command. The only way to verify success is to read the data back from the tag.An ISO18000-6B tag write operation can fail if any byte within the addressed range is locked or if the power setting is not correct. It is not uncommon for Philips and Rafsec ISO18000-6B tags to have a portion of the first eight bytes locked. Confirm the status of the specific type of tag in use.The Wa, Wt and Wv commands can be used with the ISO18000-B tag. The Wt command is used to modify data outside of the first 8 bytes in the tag and requires specification of the tag ID using the d:parameter. The Wv command is discussed at the end of this section.The format of the Wa command is as follows:}Wa,a:<blk addr>,b:<blk data>[,l:<# blks>]!where:a:<blk addr>. In ISO18000-6B, this parameter provides the address of the writeable memory block. The block size is one byte.l:<# blks>. This parameter reflects the number of blocks being written (which is equal to the number of bytes in this case).b:<blk data>. This parameter contains the actual data being written.The following command example command writes AABBCCDD to user memory at address 0x20 on a tag with ID EF04001122334455:}wt,d:EF04001122334455,a:20,b:AABBCCDD,l:4!In addition to the Wa and Wt commands, SAMSys readers also support the following ISO18000-6B operations:•Lb Lock Block•Yl Query Lock Status (returns f:0 for unlocked or f:1 for locked)Each of these operations must specify a particular tag ID with the d: parameter and block address with the a: parameter.
Tag Programming37UCODE ProgrammingWriting multiple bytes anywhere in the first eight bytes of a UCODE tag requires the use of the Wa command. Only a single tag should be present in the RF field for a Wa operation. The Wa command can be used to modify any byte in the tag. For single byte write operations, use the Wt command. The ISO18000-6B UCODE tag can emulate a 96- or 64-bit EPC ID tag by writing data to multiple locations in the tag and enabling the appropriate mode in the reader. This capability is more fully described in the Implementation of EPC Tag Data on UCODE EPC 1.19 Application Note from Philips Semiconductor. For detailed information on reader configuration for this tag, refer to the P6B Configuration Register description in the SAMSys Comprehensive Heuristic Unified Messaging Protocol (CHUMP) Reference Guide.To configure a UCODE tag for a 96-bit EPC ID of 3114F4DA34B2D05E01010101, send a Tag Reset Tr command followed by a Read Detect Rd command. Then issue the Wa commands:}Tr!}Rd!}wa,a:2,b:315E01010101,l:6!}wa,a:10,b:14F4Da34B2D0,l:6!To configure a UCODE tag for a 64-bit EPC ID of 4066771122334455, send a Tag Reset Tr command followed by a Read Detect Rd command. Then issue the Wa commands:}Tr!}Rd!}wa,a:2,b:401122334455,l:6!}wa,a:10,b:6677,l:2!
MP9311 User’s Guide38Using the Wv CommandThe Wv command is a multifunction command that performs any erase, write, and verification needed to program a tag in a specific protocol. The command can also lock the data.The format of the Wv command is as follows:}Wv,b:<EPC data>,u:<user memory>,m:<lock mask>!where:b:<EPC data> is the EPC ID to write to the tag.u:<user memory> is the user data to be written to the tag. The number of bytes varies depending on the tag.m:<lock mask> is the lock mask to indicate which tag field to lock. Each 4-bit nibble in the mask indicates the lock state to apply to a specific part of the tag. A mask nibble value of 1 locks the specific part of the tag. A mask nibble value of 0 indicates no lock is applied. For the ISO18000-6B protocol, the mask nibbles apply to the following fields:To write an EPC ID value of 332233445566778899aabbcc and verify the write, enter:}wv,b:332233445566778899aabbcc!To write the EPC ID data and lock the data, enter:}wv,b:332233445566778899aabbcc,m:1!Mask Nibble 4 3210Tag Field User Memory Unused Unused Unused EPC data
Tag Programming39Programming the Impinj EPC0 TagIn EPC0, there is no single standard for performing write operations and there are noteable differences between manufacturers. Some varieties of EPC0 tags are not writeable. This section addresses writable EPC0 tags produced by Impinj.The Wa, Wt and Wv commands can be used to write EPC0 tags. The Wv command is discussed at the end of this section.The format of the Wa command is as follows:}Wa,a:<blk addr>,b:<blk data>[,l:<# blks>][,d:<tag ID>]!where:a:<blk addr>. This parameter provides the address of a writeable memory block. The block size is one row which is two bytes. The Control Word (a:1) must be written for the desired EPC ID length.l:<# blks>. This parameter is required and is the number of bytes being written.b:<blk data>. This parameter is required and contains the data to write.d:<tag ID> . This parameter is required for the Wt command (optional for Wa) and specifies the EPC code of the tag to which the write operation applies. Typically, the Wt command would be used to modify user data in the tag. The Wt command requires specification of the tag ID using the d: parameter.In addition to the Wt command, the reader also supports the following operations:•Lb Lock Block•Yl Query Lock Status (returns f:0 for unlocked or f:1 for locked)•Td Tag DestroyThe Lock Block and Query Lock Status operations must be performed with a single tag in the RF field and do not require any parameters. The Tag Destroy operation requires d: parameter to specify a particular tag ID and the b:parameter to specify the particular kill passcode for this tag.For detailed information on these and other tag commands, refer to the Comprehensive Heuristic Unified Messaging Protocol (CHUMP) Reference Guide.

Tag Programming41Program the User Data (Impinj Zuma Tags)To program user data on a 96-bit Impinj Zuma Tag, data is written to specific Rows (must not be locked). To write 2 rows of user data to User Row 11 and 12 (b hex), enter:}Wa, a:b,b:1234abcd,l:2!Change the Passcode (Impinj Zuma Tags)To change the Passcode on an Impinj Zuma Tag, enter the following:}Wa,a:2,l:2,b:123456!where:l must equal 2b must be 6 digitsUsing the Wv CommandThe Wv command is a multifunction command that performs any erase, write, and verification needed to program a tag in a specific protocol. The command can also lock the data.The format of the Wv command is as follows:}Wv,b:<EPC data>,k:<kill code>,m:<lock mask>!where:b:<EPC data> is the EPC ID to write to the tag.k:<kill code> is the kill code to be written to the reader.m:<lock mask> is the lock mask to indicate which tag field to lock. Each 4-bit nibble in the mask indicates the lock state to apply to a specific part of the tag. A mask nibble value of 1 locks the specific part of the tag. A mask nibble value of 0 indicates no lock is applied. For the EPC0 protocol, the mask nibbles apply to the following fields:To write an EPC ID value of 332233445566778899aabbcc and verify the write, enter:}wv,b:332233445566778899aabbcc!To write the EPC ID data and lock the data, enter:}wv,b:332233445566778899aabbcc,m:1!Mask Nibble 4 3210Tag Field User Memory Unused Unused Kill code EPC data
MP9311 User’s Guide42Programming the Matrics Class 0+ TagMatrics Class 0+ tags utilize a process called Singulation. This is a process of uniquely identifying a tag in a population of tags and retieving its Electronic Product Code (EPC). For detailed information on EPC Class 0 singulation, refer to the EPC Global Class 0 specification.When a tag is requested to identify itself, it responds with different data based on its singulation mode. Class 0 and Class 0+ tags allow three modes of singulation:• ID2 - This mode responds directly with the EPC. ID2 is the fastest mode (fewest bits transmitted), but requires the reader to echo the bits back to the tag. This echo can create security issues. Also, this mode can not be read when writing the EPC, since the echo will change the EPC as you write it.• ID0 - This mode returns packets of 12 random bits that are different every time you singulate. When the reader has what it determine is the correct number, it writes the EPC. This mode is the only reliable method of singulation during writing the tag EPC.• ID1 - This mode is the same as ID0, but every singulation returns the same bit stream. The bits are random, but they are seeded from the EPC. Writing the EPC changes these bits.The singulation mode is controlled with the PE0 register and must be set prior to writing tags.Matrics Class 0+ tags contain three writable pages or memory blocks: These pages are as follows:• Page 0 – Kill code (24 bits)• Page 2 – EPC code (64 or 96 bits)• Page 3 – User data (104 bits)When Page 2 or Page 3 data is written, a 16-bit CRC is appended.The Wa, Wt and Wv commands can be used to write Matrics Class 0+ tags. The Wv command is discussed at the end of this section.The format of the Wa command is as follows:}Wa,a:<blk addr>,b:<blk data>[,l:<# blks>][,d:<tag ID>]!where:a:<blk addr>. This represents the memory page of the tag on which the write operation will occur. Values can be 0, 2 or 3, as defined previously. If this parameter is missing, it will default to 0.l:<# blks>. This parameter is required and is the number of bytes being written.b:<blk data>. This parameter is required and contains the data to write.d:<tag ID> . This parameter is required for the Wt command (optional for Wa) and specifies the EPC code of the tag to which the write operation applies.
Tag Programming43Writing Initial EPC Code to Blank Matrics EPC0+ TagsTo write the EPC code to blank tags, ID0 singulation must be used.If ID2 traversal is to be inhibited on subsequent tags, set the traversal inhibit bit in PE0. Once written, those tags will not singulate using ID2 unless the EPC code is erased and then rewritten with traversal inhibit cleared.Once a valid EPC code is written to Page 2, it cannot be overwritten unless the tag is first erased. Tag write operations using ID0 singulation cannot distinguish if a tag has previously been singulated.Each ID0 singulation will use a new random number. To prevent a single tag from continually being selected for EPC code writing, an error code is returned if the tag already has a valid EPC code and an overwrite is blocked.As stated earlier, the mode must be set prior to writing tags. A typical value for the TM0 register is b:0. A typical value for the PE0 register for writing blank tags is b:12050180. This value sets PE0 for the following:• Use ID0 singulation with 2 blocks of random bits• Retry count set to 5 (set to a 1 speeds up the write process with only 1 retry)• Scroll first turned on• Autolength EPC enabled (set the right most digits to 04 for a 64 bit and 08 for a 96 bit)To write the PE0 register, enter the following: }Cw,d:PE0,b:12050180!To sense a tag with a valid CRC and an EPC = all 00’s, write b:1a050180 to the PE0 register. The last 4 digits displayed are the CRC. You should attempt to get good read rates before trying to write to the tags.Use the “f:2” so you don’t get an e:55 for trying to overwrite a valid EPC (make sure there is only 1 tag in the field). If you are only writing the EPC code, there is no need to do a “te”, since the write command process with the f:2 always erases the memoryTo write a 96-bit EPC code to a blank tag you may need to set the PE0 register to b:1a050108, and enter the following:}Wa,a:2,b:312233445566778899aabbcc,l:c,f:2!NOTE: Writing to tags is very sensitive to the following:– RF power (Generally need more power to write than to read tags)– Tag spacing from the antenna (Need to get enough power coupled into the tag)– Orientation of the tags
MP9311 User’s Guide44Writing a Kill Code and User DataKill codes and user data can be written to any tag in the field in the same manner as the EPC code method described above, but typically a kill code and user data would be associated with a specific EPC code. Once written, you cannot read back the kill code.To write a Kill Code, enter the following:}Wa,a:0,b:112233,l:3!To write to a specific tag, enter the EPC code as the d: parameter. The following write command would write the Kill code and singulates using ID2, so PE0 singulation bits are ignored:}Wt,a:0,d:220000000000000000000003,b:112233,l:3!Writing User DataTo write user data to Page 3 on any tag, enter the following(overwrites any current data):}wa,a:3,d:112233445566778899AABBCC,l:c!To write user data to page 3 of a specific tag, enter the EPC code as the d: parameter (singulates using ID2, so PE0 singulation bits ignored):}Wt,a:3,d:30112233445566778899aabb,b:00112233445566778899aabbcc,l:d!Tag EraseTo erase a Matrics 0+ tag, use the Tag Erase Te command. Only one tag should be in the field when executing this command. All memory pages are filled with 0’s and a 16-bit CRC is appended.After erasing, the EPC code page will be filled with 0’s. Also, the user data page will have all 0’s with a 16 bit CRC appended at the end. This allows the user data page to be read with the Ra command. However, the EPC code page will return an error on Ra, since there is no valid CRC. If any page is locked, then the Te command will fail and none of the pages will be erased. To erase a tag, enter the following: }Te!
Tag Programming45Locking TagsIndividual memory pages can be locked with the Lb command. Once a page is locked, it cannot be unlocked or written. The following are typical Lock commands.To lock Page 0 (Kill code of any tag singulated using PE0 bits), enter:}Lb!To lock Page 2 (Kill code of any tag singulated using PE0 bits), enter:}Lb,a:2! (locks page 2, the EPC code of any tag singulated using PE0 bits)To lock Page 3 (User data with specific EPC code), enter:}Lb,a:3,d:220000000000000000000003!Using the Wv CommandThe Wv command is a multifunction command that performs any erase, write, and verification needed to program a tag in a specific protocol. The command can also lock the data.The format of the Wv command is as follows:}Wv,b:<EPC data>,k:<kill code>,m:<lock mask>!where:b:<EPC data> is the EPC ID to write to the tag.k:<kill code> is the kill code to be written to the reader.m:<lock mask> is the lock mask to indicate which tag field to lock. Each 4-bit nibble in the mask indicates the lock state to apply to a specific part of the tag. A mask nibble value of 1 locks the specific part of the tag. A mask nibble value of 0 indicates no lock is applied. For the EPC0 protocol, the mask nibbles apply to the following fields:To write an EPC ID value of 332233445566778899aabbcc and verify the write, enter:}wv,b:332233445566778899aabbcc!To write the EPC ID data and lock the data, enter:}wv,b:332233445566778899aabbcc,m:1!Mask Nibble 43210Tag Field Unused Unused Unused Kill code EPC data
MP9311 User’s Guide46Programming the EPC1, Generation 2 TagEPC Class1, Generation 2 (Gen2) tags can be programmed by the SAMSys UHF readers.EPC1, Gen2 tags support 4 different writable memory banks with each memory bank consisting of a series of 16 bit words. Each word can be written independently and one word is the smallest size write operation supported. In most cases, these memory banks have predefined contents and functions. The memory banks are as follows:• Access Memory (bank 0)• EPC Memory (bank 1)• TID Memory (bank 2)• User Memory (bank 3)Access MemoryThe Access Memory bank contains the 32 bit Kill Password and the 32 bit Access Password. The Kill Password is at offset 0 and the Access Password is at offset 2.EPC MemoryThe EPC Memory bank contains a CRC-16, the Protocol Control bits, and the actual EPC ID. The CRC-16 is at offset 0, the Procotol Control is at offset 1, and the EPC ID begins at offset 2.The Gen2 tag generates the CRC-16 at power up while the Protocol Control bits. The EPC ID must be set by a RFID interrogator. The Protocol Control bits must be set initially on a blank tag prior to, or in conjunction with, writing the EPC ID. Once these bits are set, multiple writes can occur to the EPC ID. NOTE: After writing the EPC ID, a tag will respond but the CRC will be invalid since the tag only generates the CRC on power up. Therefore, the tag must be reset via a RF Off/On cycle following the write and prior to new tag inventory attempts. If the reader is being operated with GCW = 0, this reset is not needed since the RF field is automatically turned off at the completion of the write command.TID MemoryThe TID Memory bank contains an 8 bit ISO/IEC 15963 allocation class identifier (the value of 111000010b is used for EPC Global). This identifier is located in the lower half of the word at offset 0. A tag may contain manufacturer specific data at offset 2 and above.User MemoryThe User Memory bank contains user specific data and its memory organization is user defined.
Tag Programming47Writing the TagThree CHUMP commands can be used to write to an EPC1, Gen2 tag: Wa, Wt, and Wv. Wa writes to any tag in the field and is typically used to write the EPC ID to tag. Wt writes to a specific tag, as defined in the input parameter list, and is typically used to write to user data on a tag. Wv is a multifunction command that erases, writes, and verifies a tag.Using the Wa CommandThe format of the Wa command is as follows:}Wa,a:<blk addr>,b:<blk data>[,l:<# blks>][,s:<offset>] [,f:<xxx>]!where:a:<blk addr> is the block address (0 by default). For EPC1, Gen2 0=Reserved,1=EPC, 2=TID, 3=USER memory bankb:<blk data> is the block data to write. Must be 16-word multiple.l:<# blks> is the length in 16-bit words. Defaults to length of data if missing.s:<offset> is the offset to start the write (EPC1, Gen2 only). Defaults to 0 if.f:<xxx> is protocol specific flag data. Set f=1 for read back/verify. EPC1, Gen2 tags provide SUCCESS/FAIL feedback. Defaults to 0.To write an EPC ID value of 332233445566778899aabbcc onto a tag with the Protocol Control field set for a 96 bit tag, enter:}wa,a:1,s:2,b:332233445566778899aabbcc! To add the length field, enter:}wa,a:1,s:2,b:332233445566778899aabbcc,l:6! To request a read/verify cycle following the write operation, enter:}wa,a:1,s:2,b:332233445566778899aabbcc,l:6,f:1! In order to write an EPC ID to a blank tag, the Protocol Control bits must also be set. This can be accomplished in a single write command since the Protocol Control bits are contained in the same memory bank as the EPC ID. Following the previous example, the command would include setting the Protocol Control to 3000 as follows:}wa,a:1,s:1,b:3000332233445566778899aabbcc!The Kill and Access Passwords are contained in the Reserved Memory bank. Each password can be written with separate Wa commands or a single command:To write a 32-bit Access password at offset 2, enter:}wa,a:0,s:2,b:55667788!To write both Access passwords with a single command, enter:}wa,a:0,b:3322334455667788!
MP9311 User’s Guide48Using the Wt CommandThe Wt command can also be used to write the Kill and Access passwords and the TID and User Memory banks. The Wt command requires the use of the EPC ID of the tag.The format of the Wt command is as follows:}Wt, b:<data> ,d:<tag id> a:<block address >[,l:<length>] [,s:<offset>][, f:<flags>]! where:a:<block address> is the block address (0 by default). For EPC1, Gen2 0=Reserved,1=EPC, 2=TID, 3=USER memory bankb:<blk data> is the block data to write. Must be 16-word multiple.d:<tag ID> is the tag identification.l:<# blks> is the length in 16-bit words. Defaults to length of data if missing.s:<offset> is the offset to start write (EPC1, Gen2 only). Defaults to 0 if missing.f:<xxx> is protocol specific flag data. Set f=1 for read back/verify. EPC1, Gen2 tags provide SUCCESS/FAIL feedback. Defaults to 0.To write the Kill password to a tag with EPC ID= 332233445566778899aabbcc, enter:}wt,d:332233445566778899aabbcc,a:0,b:33223344!
Tag Programming49Using the Wv CommandThe Wv command is a multifunction command that performs any erase, write, and verification needed to program a tag in a specific protocol. The command can also lock the data.The format of the Wv command is as follows:}Wv,b:<EPC data>,k:<kill code>,c:<access code>, i:<TID data>,u:<user memory>,m:<lock mask>!where:b:<EPC data> is the EPC ID to write to the tag.k:<kill code> is the kill code to be written to the reader.c:<access code> is the access code to be written to the tag.i:<TID data> is the TID data to be written tot he tag. The number of bytes varies depending on the tag.\u:<user memory> is the user data to be written to the tag. The number of bytes varies depending on the tag.m:<lock mask> is the lock mask to indicate which tag field to lock. Each 4-bit nibble in the mask indicates the lock state to apply to a specific part of the tag. A mask nibble value of 1 locks the specific part of the tag. A mask nibble value of 0 indicates no lock is applied. For the EPC1-2, the low order bit of each nibble indicates if the permalock bit should be set, and the next higher bit indicates if the pwd-write bit should be set.For the EPC1-2 protocol, the mask nibbles apply to the following fields:To write an EPC ID value of 332233445566778899aabbcc and verify the write, enter:}wv,b:332233445566778899aabbcc!To write the EPC data, a kill code of A391742F, an access code of 73D97412, and lock the EPC data and access code, enter:}wv,b:30112233445566778899aabb,k:A391742F,c:73D97412,m:00202!In this example, the lock mask of m:00202 = 0010 0000 0010b and indicates that a pwd-lock is requested for nibble 2 (access code) and a pwd-lock is requested for nibble 0 (EPC data).Mask Nibble 43210Tag Field User memory TID data Access code Kill code EPC data
