Operation
Note!
UII/EPC
If there are multiple tags in the measurement range with the same UII/EPC, the identical tags
are reported with Status A.
Enhanced Read Special Read-Only Code ES
This command continuously attempts to read the UII segment from tags according to EPC
Gen2 (ISO/IEC 18000-63). If the <SpecialFixcode> of a tag is read, this is reported once to the
control interface. If there is no tag in the measurement range, or if the tag leaves the
measurement range, a status 5 is reported to the control interface.
Command: ES <ChanNo> 0 <CHCK> <ETX>
Response: <Status> <ChanNo> <Length> <SpecialFixcode> <CHCK> <ETX>
Example:
ES10 continuously reads the UII segment.
The tag type determines the maximum length of the UII/EPC. The actual length of the UII/EPC
is defined via the protocol control word <PC>. The data is structured as follows:
<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 bytes long.
<UII/EPC> contains the usage data.
Note!
UII/EPC
If there are multiple tags in the measurement range with the same UII/EPC, the identical tags
are reported with Status A.
Single Write Special Read-Only Code SP
This command writes a <Length> byte long UII/EPC code to tags according to EPC Gen 2
(ISO/IEC 18000-63).
Command: SP <ChanNo> <Length> <SpecialFixcode> <CHCK> <ETX>
Response: F <ChanNo> 0001 <CHCK> <ETX>
The data length <Length> must be a whole number multiple of 2 bytes because in accordance
with EPC Gen 2 (ISO/IEC 18000-63), <UII/EPC> must be written in 16-bit words. Only the
lengths 2

hexadecimal format, and includes the length of PC and UII/EPC. If a UII/EPC of 96 bits is
written, this results in 2 + 12 = 14 bytes = 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 bytes 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 bytes = 14 bytes
