IUH-F192-V1-*
Operation
Kill UHF Tag KI
This command sets a UHF tag to a state where no further access is possible. The command
can be executed only if a valid password has previously been set in segment Bank 00 via the
command SW. See chapter 3.2.3. The password must have at least 1 non-zero bit.
<UIILength> = Mask length for the UII/EPC in bits, values: 00 ... FF, always begins at Address 0.
The information is entered as 2 hex
ASCII
characters.
<UIIData> = Specification of the mask for the UII, in octets
<PassWord> = Password for killing a UHF tag, 4 octets
<RecomBits> = Recommission bits, always set to zero
Example:
KI10018.E2.00.90abcd.00 kills a UHF tag with a UII starting ".E2.00.90" and using the pass-
word "abcd."
6.5 Filter Commands
Each read or write command can access one, several, or all tags in a measurement range. The
process is controlled by filter masks, which are managed via the commands Set Filter Mask
(FI) and Activate/Deactivate Filter (MF). These commands allow you to detect specific tags in
the measurement range. see chapter 6.5.
Set Filter Mask FI
Using command FI, you can define a filter mask for accessing the tags located in the box. You
can define up to 3 filters (0-2). The following syntax is used:
<MemBank> = Memory segment to which the filter is to be applied. The information is entered
as one hex
ASCII
character.
<StartAddress> = Address of the bit at which the filter mask begins. Specified in hex
ASCII
. Val-
ues: 0000 FFFF
<MaskLength> = Length of the mask in bits. The information is entered as 2 hex
ASCII
charac-
ters.
<MaskData> = Defines the actual filter mask
Example:
There are three tags in the measurement range of the read/write head. Each tag has a unique
identifier of <PC> & <UII/EPC>:
If you want to detect the 3rd tag, the filter mask is: FI101000001028.34.00.E2.00.90
