 Setting Communications Conditions
This command sets parameters that are related to the operation of communications with RF Tags.
Any changes to the settings that are made with this command are effective immediately. (There is no
need to reset the Reader/Writer to save the settings.)
 Communications Option Setting
You can set the communications option of the Reader/Writer to Once, Repeat, or FIFO Repeat.
Name
Once
Repeat
FIFO Repeat
 RF Tag Communications Speed Setting
You can set the speed for communications between the Reader/Writer and RF Tags.
High speed (default)
Normal speed
 Write Verification
You can set whether to verify write processing.
Enabled (default)
Disabled
 Communications Diagnostic
You can set whether to the communications diagnostic of the Reader/Writer.
Disable (default)
Enable
When the Reader/Writer receives a command, it communicates with an RF Tag and returns a
response.
When the Reader/Writer receives a command, it repeatedly communicates with RF Tags and
returns a response when communicating with an RF Tag was possible.
Once an RF Tag has been communicated with, communications will not be performed for it again
as long as it remains in the communications field.
When the Reader/Writer receives a command, it repeatedly communicates with RF Tags and
returns a response when communicating with an RF Tag was possible.
After communicating with an RF Tag once, operation for that RF Tag is stopped. When the Reader/
Writer communicates with an RF Tag, there must be only one RF Tag for which operation is
possible in the communications field. The Reader/Writer will not communicate with the same RF
Tag again.
This setting reduces the communications time by reading more than one block at the same time
with an air interface. However, if errors are detected during communications due to ambient noise
or other factors, processing is redone from the beginning, which can actually increase the
communications time.
This setting provides more stable communications quality by reading one block at a time, in the
same way as for the earlier V680. Although the normal communications time is longer, processing
can be continued during communications if errors are detected due to ambient noise or other
factors, which can actually reduce the communications time.
After processing a write operation, the memory area that was written in the RF Tag is read and
verified to confirm that the write operation was performed normally.
Write processing is not verified.
The Reader/Writer does not perform communications diagnostic.
This function diagnoses the communications leeway whenever the Reader/Writer communicates
with an RF Tag, displays the results on an operation indicator, and reports the results to the host
device. It will help you achieve a more stable Reader/Writer and RF Tag installation and enable
monitoring the status of operations.
