5.2 Writing data to Tag
Some kinds of tags have an internal memory that can be written with user data.
Please check the tag characteristics with the manufacturer.
Data can be written into the Tags with PC application (see Support software
)
in 2 formats as;
• ASCII : normal text
• EPC : the EPC data must according to EPC Tag Data Standards.
(Automotive Industry Action Group’s (AIAG) B-11 RFID Item Identification
Standard.)
5.3 Downloading records from the reader
The ST100 has an internal non-volatile memory where all reading records are kept.
They can be downloaded to a PC through a USB connection to a PC running a
special application. Other options are available on demand.
5.3.1 Downloading through USB
The ST100 can be connected to any device with a USB port. The contents of the
memory can then be downloaded using this port.
The supplied PC application “RFID Note” contains this feature and creates a
comma separated value (CSV) file for use with other applications.
If you want to integrate the download feature in your own application, please
contact your Advanced ID distributor. (see Support software
)
5.3.2 Other download possibilities
The flexible architecture of the ST100 enables upgrade to other connection
possibilities. Advanced ID has the possibility to upgrade your unit for Ethernet,
Wireless LAN or other ISN band RF connection. Please contact Advanced ID for
the options available.
6. Configuration
The stand alone reader ST100 can be configured to fit particular applications. The
configuration can be done with the supplied PC application “RFID Note”. (see
Support software)
6.1 Data length and Start address
The ST100 can store user data into tags as explained before. The number of bytes
to be stored and the internal tag address where that data is stored can be set. Data
is written in blocks of 8 bytes to the tag. Therefore the data length must be always
a multiple of 8. The PC application enables this setting accordingly.
The number of bytes is limited to 32. For application demanding more bytes,
please contact your Advanced ID distributor.
The tag address where data will start to be written depends on the tag’s internal
chip. Please refer to the chip manufacturer’s datasheet for details.
As a hint, ISO 16000-6B tags internal user memory start at address 0x12 (18) and
EPC Class 1 Gen 2 start at 0x00 (0).
Please contact your Advanced ID distributor for more details. (see Support
software)
6.2 Read mode
To set the type of tags that will be read. The types of tags that can be read by the
reader are as follow.
• ISO-18000-6 Type B (U-Code, HSL)
• ECP Class 1 General 2
6.3 Reader Timeout
The same tag will be stored in the memory only once per reading session. This
means if you read tag A now and you read it again and again, it will be stored only
once in the memory during this reading session. A new reading session starts
automatically when the Reader timeout elapses, when the reader comes out of
sleep mode or when the CLEAR key is pressed.
A Reader timeout occurs when the reader does not read any tag for the specified
period of time.
Depending on the application, this time can be set.
If, for example, you have an application where it is unlikely that the same tag
comes into read range again in a short period of time (ex. conveyor belt) you
should set this value to 1 or 2 seconds at most. This means that if the time
between 2 consecutive tags is more that 2 seconds you will have a new reading
session for each tag, meaning that all tags passing will be read and stored, even if
they come more than once in read range.
On the contrary, if you have an application where the same tag may come into read
range in a reading session (ex. scanning a herd of sheep when they are in the
corral) you would like to prevent the same animal’s reading to appear again. In this
case you should set the timeout to 2 minutes.
You can set Reader Timeout with PC application. (see Support software
)
Note : the reader timeout has no influence on the tag counting feature.
6.4 Operation mode
You can set Operation mode with PC application (see Support software) in 2
modes as follow;
• Read ID – Reader will read only Tag ID.
