Installation Installing the RF Command Suite Application The 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.
MP9311 User’s Guide Setting Transmit Power - TD0 Output 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).

Appendix A Tag Programming This appendix describes how to program tags of varying protocols using CHUMP commands sent from a terminal or console.
MP9311 User’s Guide Overview of the Tag Writing Commands Tag 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.
Tag Programming Programming the EPC1 Tag SAMSys 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.
MP9311 User’s Guide In 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 Destroy The 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.
Tag Programming Programming the ISO18000-6A Tag Both 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.
MP9311 User’s Guide Programming the ISO18000-6B Tag In 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.
Tag Programming UCODE Programming Writing 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.
MP9311 User’s Guide Using the Wv Command The 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:,u:,m:! where: b: is the EPC ID to write to the tag. u: is the user data to be written to the tag. The number of bytes varies depending on the tag.
Tag Programming Programming the Impinj EPC0 Tag In 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.
MP9311 User’s Guide Program a 96-Bit EPC (Impinj Zuma Tags) To write a 96-bit EPC on an Impinj Zuma EPC0 tag, enter the following: }te! }wa,a:1,l:1,b:7! Once the tag has been set to 96 bit, use a single Wa command for subsequent Tag ID writes: }Wa,a:4,l:6,b:306c50fd76d803cf02f47f5f,f:3! where: a:4 is the start of the EPC l:6 is the length in rows b:xxxx is the 96-bit EPC code f:3 is the command to calculate the CRC. The CRC is calculated and written to the row following the EPC code.
Tag Programming Program 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).
MP9311 User’s Guide Programming the Matrics Class 0+ Tag Matrics 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.
Tag Programming Writing Initial EPC Code to Blank Matrics EPC0+ Tags To 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.
MP9311 User’s Guide Writing a Kill Code and User Data Kill 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.
Tag Programming Locking Tags Individual 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.
MP9311 User’s Guide Programming the EPC1, Generation 2 Tag EPC 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.
Tag Programming Writing the Tag Three 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.
MP9311 User’s Guide Using the Wt Command The 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: ,d: a:[,l:] [,s:][, f:]! where: a: is the block address (0 by default). For EPC1, Gen2 0=Reserved,1=EPC, 2=TID, 3=USER memory bank b: is the block data to write.
Tag Programming Using the Wv Command The 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:,k:,c:, i:,u:,m:! where: b: is the EPC ID to write to the tag. k: is the kill code to be written to the reader.
