Chapter 4 - BRI Commands Syntax: Parameters: BLOCKPERMALOCK [flex_query_selector] LOCK [data_field]*[TAGTYPE=tagtype list] [WHERE ] [PASSWORD=] [flex_query_selector] = This parameter modifies the command for certain types of EPCC1G2 tags. For details, see "FLEXQUERY" on page 47. = Specifies a bank, offset, length, and mask in which the Permalock field is to operate. For example: HEX(:,)=H = The bank should always be 3. = This parameter is the BlockPtr parameter of the EPCGlobal Gen2 specification. It specifies the starting address for the Mask field in units of 16 blocks. For example, 0 indicates block 0, 1 indicates block 16. = This parameter is the BlockRange parameter of the specification. It specifies the range of the Mask field starting at and ending (16*)1 blocks later. = Contains a bit mask indicating which blocks in the range should be locked. One bits indicate that a block should be locked. Zero bits indicate that a block is left alone. The most significant bit of corresponds to the lowest address block. must be specified as a hexadecimal string and it must contain 16 bits for each unit of . For example, when is 1, must consist of 2 hex pairs. Examples: These examples demonstrate how to use the BLOCKPERMALOCK command. Example 1: BLOCKPERMALOCK LOCK HEX(3:0,1)=H0800 H0123456789ABCDEF01234567 LCKOK Lock the 5th block of user memory. Example 2: BLOCKPERMALOCK LOCK HEX(3:2,1)=H0001 H0123456789ABCDEF01234567 LCKOK Lock the 48th block of user memory. Example 3: BLOCKPERMALOCK LOCK HEX(3:0,1)=H0800 HEX(3:2,1)=H0001 H0123456789ABCDEF01234567 LCKOK Lock the 5th and 48th blocks of user memory. Example 4: BLOCKPERMALOCK LOCK HEX(3:0,3)=H080000000001 H0123456789ABCDEF01234567 LCKOK Lock the 5th and 48th blocks of user memory. Basic Reader Interface Programmer Reference Manual 39

Chapter 4 — BRI Commands
Basic Reader Interface Programmer Reference Manual
39
Syntax:
BLOCKPERMALOCK [flex_query_selector] LOCK
[data_field]*[TAGTYPE=tagtype list] [WHERE <data condition>]
[PASSWORD=<access_password>]
Parameters:
[flex_query_selector] = This parameter modifies the command for certain types of
EPCC1G2 tags. For details, see
“FLEXQUERY” on page 47
.
<data_field> = Specifies a bank, offset, length, and mask in which the Permalock
field is to operate. For example:
HEX(<Bank>:<Offset>,<Length>)=H<Data>
<Bank> = The bank should always be 3.
<Offset> = This parameter is the BlockPtr parameter of the EPCGlobal Gen2
specification. It specifies the starting address for the Mask field in units of 16
blocks. For example, <Offset> 0 indicates block 0, <Offset> 1 indicates block 16.
<Length> = This parameter is the BlockRange parameter of the specification. It
specifies the range of the Mask field starting at <Offset> and ending (16*<Length>)-
1 blocks later.
<Data> = Contains a bit mask indicating which blocks in the range should be
locked. One bits indicate that a block should be locked. Zero bits indicate that a
block is left alone. The most significant bit of <Data> corresponds to the lowest
address block. <data> must be specified as a hexadecimal string and it must contain
16 bits for each unit of <length>. For example, when <length> is 1, <data> must
consist of 2 hex pairs.
Examples:
These examples demonstrate how to use the BLOCKPERMALOCK command.
Example 1:
BLOCKPERMALOCK LOCK HEX(3:0,1)=H0800
H0123456789ABCDEF01234567 LCKOK
Lock the 5th block of user memory.
Example 2:
BLOCKPERMALOCK LOCK HEX(3:2,1)=H0001
H0123456789ABCDEF01234567 LCKOK
Lock the 48th block of user memory.
Example 3:
BLOCKPERMALOCK LOCK HEX(3:0,1)=H0800 HEX(3:2,1)=H0001
H0123456789ABCDEF01234567 LCKOK
Lock the 5th and 48th blocks of user memory.
Example 4:
BLOCKPERMALOCK LOCK HEX(3:0,3)=H080000000001
H0123456789ABCDEF01234567 LCKOK
Lock the 5th and 48th blocks of user memory.
