CHAPTER FOUR – DATA CAPTURE

3. If you want to check on how the selected triggering works, direct your
PL3000 at some surface so that you can see the aimer/scan light when
you press the ‘Scan’ key. Pressing the ‘Scan’ key gets also the applet to
display the ‘Scan’ page, meaning that if you are not satisfied with the
trigger mode you may return to the step 1.
4. Press the ‘ok’ key; the selected trigger mode is in use.
Changing Scanning Timeout
Before you begin, open the ‘NID Scanner’ control panel applet (see section
‘Control Panel’ on page 30).
To set the scan timeout:
1. Select the ‘Misc’ tab in the NID Scanner applet
2. Enter timeout value (in seconds) of your choice in the ‘Scan Timeout’ text
field.
3. If you want to check if the selected value is appropriate time to wait for the
scanner until it gives up trying, direct your PL3000 at some surface so that
you can see the aimer/scan light when you press the ‘Scan’ key. Pressing
the ‘Scan’ key gets also the applet to display the ‘Scan’ page, meaning that
if you are not satisfied with the timeout you may return to the step 1.
4. Press the ‘ok’ key; the selected timeout value is stored in the registry.
RFID TAG READERS
The PL3000 is available with two RFID reader options. The dividing line
between the readers is what type of RFID tags they are able to read. For example,
a tag’s coupling mechanism determines one of the main fits. This coupling
mechanism has also an influence on reading operation in general, such as on the
read range between the reader and the tag. Along with range, the coupling
mechanism strongly affects which frequency the tag can use. In this respect, the
PL3000 with its RFID reader options is suitable for applications using either the
inductive coupling tags operating in the 13.56MHz frequency band (ISO 15693
tags and ICODE tags) or the backscatter coupling tags operating from 865MHz to
868MHz (EPC UHF Class 1 Gen2 tags, aka EPC UHF Gen2 or ISO18000-6C
tags).
Be aware that there are other factors that have an influence on the
communication between the tag and the reader. In addition to the coupling, the
interaction between the tag and the reader includes the protocol to exchange
messages and information stored on tags. There are also different bodies that
make the standardization of RFID tags. For example, there are ISO 18000 series of
standards and EPC (Electronic Product Code) standards. The ISO 18000
standards are concerned only an air interface but the EPC standards also deal with
such as EPC coding structure, object naming service, tags’ physical
implementation, and application-level interface.
