Tag Singulation

The following is a simplification of the processReader sends RESET to all tagsReader tells all tags to roll a random number in the

range of zero to Q. That number is the tags slot orposition in line.


14/136


Tag Singulation

Reader sends RESET to all tagsReader tells all tags to roll a random number in the range ofzero to Q. That number is the tags slot or position in line. Assume Q=4 which means 16 slots

Tag Singulation

Once tag is read by the reader it remains quiet for therest of the singulation processIf tag momentarily looses power it will reset and talk

again.This is very bad when trying to read a large number otags.

Tags regularly loose power as they pass an antenna.Tag Persistence helps resolve this issue (Sessions)

BRI ATTRIBUTES

Allow you to configure the reader.Select antennas, set tag type, etc.

Not all attributes are available on all reader platforms

IF61 you cannot set baud rate, TTY, echo, or checksumsWe do add new attributes as we add more features tothe readers.

When issuing attribute commands you must alwaysinclude the keyword ATTRIB.


31/136


ATTRIB Command Structure

To GET an attribute value: ATTRIB For example: ATTRIB IDTRIES

Will return: IDTRIES=1OK>To SET an attribute value:

ATTRIB =

For example: ATTRIB IDTRIES=2 Will return: OK>


32/136


ATTRIB Command

The ATTRIB command will list all attributes availabon that reader platform.Not all attributes are available on all reader platforms

34/136


Communication Attributes

Serial readers only.Cannot be set when using the IDL drivers. ATTRIB BAUD

Default value is 115200. ATTRIB TTY=ON/OFF ATTRIB ECHO=ON/OFF

For applications, its best to leave this OFF.


35/136


Communication Attributes

ATTRIB XONXOFF=ON/OFFDefault is OFF

ATTRIB CHKSUM=ON/OFF

To disable checksums use the following command: ATTRIB CHKSUM=OFFC9Where C9 is the checksum for that command.

Checksums ARE case sensitive so this command mustbe entered in upper case as shown above!


36/136


Report Attribute Settings

ATTRIB IDREPORT=ONReader will return the ECP ID for each tag read or written to.Default is ON.

38/136


Attribute Settings: TAGTYPE

Can have multiple tag types separated by a comma ATTRIB TAGTYPE=EPCC1G2,ISO6BG2Multiple tag types slows down the reader.

ATTRIB TAGTYPE=MIXED does NOT enableepcc1g2 tag type. It is only enables ISO tag types.


39/136


Attribute Settings: FIELDSTRENGTH

Sets the RF power level per port.Reader controls max and min values so you cannotviolate your local regulations

Min value = 15 dbiMax value = country specificCan be set in DB

ATTRIB FIELDSTRENGTH=30db,30db,30db,30dbCan be set as a % of max strength or in DB

ATTRIB FIELDSTRENGTH=100,100,100,100


40/136


Attribute Settings

ATTRIB ANTSGets/Sets active antennas

ATTRIB ANTS=1,2,3,4

Sets all four antennas as active ATTRIB ANTS=4

Sets antenna 4 as active

ATTRIB ANTS=2,4Sets antennas 2 and 4 as active


41/136


Attribute Settings: INITIALQ

Gets/Sets the initial number of tag slots used in theanti-collision algorithm.# of slots = 2^Q

Once a collision is detected the reader willautomatically adjust the Q value upward.For best performance you want to minimize the

number of empty slots.

Attribute Settings: RDTRIES

ATTRIB WRTRIES=3


45/136


Attribute Settings: SESSION

ATTRIB SESSION=Sets tag persistence

What is persistence?

When a tag momentarily loses power during the tagreading process, will it remember if its already been readPersistence sets the length of time a tag will remember ibeen read.

Critical when reading a large number of tags


46/136


Attribute Settings: SESSION

Session = 0No persistenceBest for reading single tagsBest for making tags/second measurements

Session = 1Max 5 seconds persistence.With Intermec readers we have found session one provides themost consistent read rates when reading large numbers of tags.

Session = 2 and Session = 3Share the same persistence features.Min persistence time of 2 seconds.


47/136


Attribute Settings: TIMEOUTMODE

ATTRIB TIMEOUTMODE=ON/OFFEnables the use of timeouts instead of tries. Attrib SCHEDOPT=1 overrides this attribute.

Timeouts are the preferred mode.


48/136


Attribute Settings: IDTIMEOUT

ATTRIB IDTIMEOUT=Time defined in millisecondsTotal time the reader will try to read tags.

This time is an approximate value. ATTRIB IDTIMEOUT=2000

Reader will read tags for 2 seconds.


49/136


Attribute Settings: ANTTIMEOUT

ATTRIB ANTTIMEOUT=Time defined in millisecondsTime the reader will try to read tags on an antennabefore switching to the next antenna. After time expires the reader will switch to the nextantenna. ANTTIMEOUT cannot exceed IDTIMEOUT

Idtimeout=1000 and anttimeout=2000: means reader wiread for a total of 1 second on the first antenna.


50/136


Attribute Settings: IDTRIES

ATTRIB IDTRIES=Sets the number of times to cycle through theantennas.

No time associated with tries, the more tags in the fiethe longer the read will take.I recommend IDTRIES=1


51/136


Attribute Settings: ANTTRIES

ATTRIB ANTTRIES=Sets the number of inventory rounds to run beforeswitching antennas.

I recommend ANTTRIES=1


52/136


Attribute Settings: INITTRIES

ATTRIB INITTRIES=Sets the number of times to cycle through IDTRIES oIDTIMEOUT.

Functions as a multiplierINITITRIES x IDTRIESINITTRIES x IDTIMEOUT

I recommend INITTRIES=1NO advantage to setting it higher than one.


53/136


Tries vs. Timeouts ?????

Depends on what you are trying to do.Timeouts are better when you are reading a largenumber of tags.Will talk about this more later.For EPCC1G2 Ive found that TRIES dont mattermuch, just set them to ONE.

IDTRIES=1 ANTTRIES=1INITTRIES=1


54/136


Attribute Settings: SCHEDOPT

ATTRIB SCHEDOPT=0/1Controls how the reader cycles through the antennas.Originally added to make readers more responsive to

commands while reading very large groups of tagswhen in continuous read mode.More important for all readers EXCEPT the IF61.


55/136



SCHEDOPT = 0DisabledReader will use attributes as defined.


56/136



SCHEDOPT = 1EnabledDuring continuous reads, reader will check for incoming

commands and execute them.Makes reader more responsive when reading a largenumber of tags.


57/136



SCHEDOPT = 1Overrides ATTRIB TIMEOUTMODE=OFFWill use IDTIMEOUT, ANTTIMEOUT if they are non-

Disable timeouts by setting one or both to zeroIf IDTIMEOUT=0 will uses IDTRIESIf ANTTIMEOUT=0 will use ANTTRIES

I recommend setting ANTTIMEOUT=0 and ANTTRIE

Data Field Definitions

Optional fields of tag specific data that can be added to READ andWRITE commands.Will be returned with the EPCID.The following fields are READ ONLY: ANT

Antenna that tag was read on.Values: 1,2,3,4

COUNTNumber of times tag was read.

TIMETime stamp of when tag was first read in milliseconds.Not a real time but an internal timer that is reset when reader is powered up.

When programming EPCIDs make sure there is onlyone tag present or they will all be programmed withthe SAME EPCID.If necessary use a WHERE clause to singulate a tagfor reading or writing

Reading and Writing Large Amounts of Data


99/136



The larger the amount of data you want to read/writethe more likely it will fail (air protocol issues)Best to break the large field up into small fields

If one small field fails you only have to READ/WRITthat field, not ALL of the data.Much more efficient overall.

ACCESS Password


124/136


Access passwords control WRITE access to memorybanks.You must program a valid, non null access passwordbefore you can PROTECT or LOCK a tag. Access password is located at membank 0, bytes 4-8You must PROTECT the password before it becomesactive.

ACCESS Password


125/136


Reading Access passwordR HEX(0,4,4)

reads the access password if its not protectedReturns PVERR if protected

R HEX(0,4,4) password=h11111111reads the access password if it is protected

Set Access PasswordW HEX(0:4,4)=H11111111

Command: PROTECT ON


126/136


Locks entire memory bank so that it cannot bewritten to with out the proper password.When passwords are protected you cannot read orwrite them with out the password.

Cannot use keywords such asEPCID, TAGID

For example the following will NOT work

PROTECT ONEPCID PASSWORD=H11111111Returns ERR

Command: PROTECT ON

Protect Memory Bank 1, EPCIDPROTECT ON HEX(1:4,2) PASSWORD=H11111111Now you can read EPC ID but not write to it.Entire memory bank is protected

Command: PROTECT OFF


129/136


Setting PROTECT OFFPROTECT OFF HEX(1:4,2) PASSWORD=H11111111Now you can write EPC ID.

Command: PROTECT Permanent

Is irreversible!Protecting ACCESS password

PROTECT ON PERMANENT HEX(0:4,4)PASSWORD=H11111111Password cannot be unprotected.

Command: PROTECT Permanent

You can also unlock a memory bank permanently sothat it can never be protectedPROTECT OFF PERMANENT HEX(0:4,4)PASSWORD=H11111111

Password cannot be protected.PROTECT OFF PERMANENT HEX(1:4,2)PASSWORD=H11111111

EPC bank cannot be protected.
