IUH-F190-V1-*, IUT-F190-R4-V1*
Operation
Note
The memory bank (MB) parameter defines the bank accessed by this command. see
"Memory Module for Tag Accesses to the "Memory Bank" MB" on page 52.
Note
16-Bit Read/Write Commands
The read/write commands SR, ER, SW, and EW are interpreted as 16-bit versions by means of
a preceding # symbol.
The 16-bit read/write commands behave in the same way as the 32-bit versions.
• 16-bit commands write or read a word with a length of 2 bytes.
• 32-bit commands write or read a word with a length of 4 bytes.
Example:
#SW1000202ABCD corresponds to SW1000101ABCD
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.
Command:
Response:
<UIILength> = Mask length for the UII/EPC in bits, values: 00 ... FF, always begins at Address 0.
The information is entered as 2 hex
<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."

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:
Command:
Response:
<MemBank> = Memory segment to which the filter is to be applied. The information is entered
as one hex
