Operation
Command:
Response:
The data length <Length> must be a whole number multiple of 2 octets because in accordance
with EPC Gen 2 (ISO/IEC 18000-63), <UII/EPC> must be written in 16-bit words. Only the
lengths 2
dec
hexadecimal format, and includes the length of PC and UII/EPC. If a UII/EPC of 96 bits is writ-
ten, this results in 2 + 12 = 14 octets = E
<Length> = Length of the <SpecialFixcode> in ASCII
<SpecialFixcode> = <PC> & <UII/EPC>
<PC> corresponds to the protocol control word in accordance with EPC Gen 2 (ISO/IEC
18000-63), 2 octets long.
<UII/EPC> contains the usage data.
Example:
SP1E.30.00.30.14.F7.33.7C.00.1F.00.00.03.1C.6E writes the value ".30.00" for <PC>, and the
UII/EPC code ".30.14.F7.33.7C.00.1F.00.00.03.1C.6E" with a length of 2 + 12 octets = 14
octets to IDENTControl channel 1.
When using this command, make sure that the protocol control word contains the correct
length of the following UII/EPC. If this is not executed correctly, the complete data is not output
on the subsequent read operation because the command SS uses the length in the protocol
control word for the output.
In accordance with EPC Gen 2 (ISO/IEC 18000-63), the protocol control word consists of two
octets. The five highest value bits denote the length of the <UII/EPC> in words (= 16 bit):
00000
bin
00001
bin
00010
bin
...
11111
bin
The meaning of the remaining bits is described in EPC Gen 2 (ISO/IEC 18000-63). If a UII/EPC
has the length 12 octets, i.e., 6 words (00110
control word corresponds to 00110000 00000000
not equal to 0, this produces a different protocol control word.
Note
Several Tags in the Measurement Range
If there is more than one tag in the measurement range when this command is run, the UII is
written to the first tag only. Status A is output for all other tags.
Single Read Words SR
