Read/Write Commands

The tag's memory structure is based on the following read/write commands in accordance with
EPC Gen 2 (ISO/IEC 18000-63). See chapter 4.2.3.
Single Read Read-Only Code SF
One attempt is made to read a read-only code (TID). The read-only code is 4, 8, or 12 bytes
long, and comprises a 4-byte part number, which denotes the tag type, and optionally a tag
with a unique serial number of 4 or 8 bytes. Details see chapter 4.2.3.
Command: SF <ChanNo> <CHCK> <ETX>
Response: <Status> <ChanNo> <Luii> <UII> <Length> <Fixcode> <CHCK> <ETX>
<Length> = Length of the <Fixcode> in ASCII
Example:
SF1 reads the read-only code to IDENTControl channel 1.
Enhanced Read Read-Only Code EF
This command continuously attempts to read a read-only code (TID). If a read-only code 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 message is reported to the control
interface.
Command: EF <ChanNo> <CHCK> <ETX>
Response: <Status> <ChanNo> <Luii> <UII> <Length> <Fixcode> <CHCK> <ETX>
<Length> = Length of the <Fixcode> in ASCII
Example:
EF1 continuously reads the read-only code to IDENTControl channel 1
Single Read Special Read-Only Code SS
This command reads the UII segment from tags according to EPC Gen2 (ISO/IEC 18000-63).
Command: SS <ChanNo> 0 <CHCK> <ETX>
Response: <Status> <ChanNo> <Length> <SpecialFixcode> <CHCK> <ETX>
Example:
SS10 reads the entire 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.
