Communications with the RF Tag
There are four types of communications specifications for communicating with RF Tags using the
Hand-held Reader/Writer.
Depending on the command, there are limitations on the communications specification that can be used.
For communication specifications that can be used, refer to
V600 and V680 Command Comparison
in this chapter.
Single Trigger (ST) Communications Specifications
After the antenna end of the Hand-held Reader/Writer has been moved close to an RF Tag, a single
trigger (ST) communications specification is sent from the host device to communicate with the RF
Tag.
1.
Move the antenna end of the Hand-held Reader/Writer close to the RF Tag.
2. Send the command from the host device to the Hand-held Reader/Writer.
3. The Hand-held Reader/Writer will communicate with the RF Tag.
4. A response will be returned from the Hand-held Reader/Writer to the host device.
If communications end normally, the operation indicator (LED) will light green and then turn OFF.
If an RF Tag is not detected within the Hand-held Reader/Writer's communication area when the com-
mand is sent from the host device, an RF Tag Non-existent Error will occur. At this time, the operation
indicator will flash red.
