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.
Host device
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.

When the Hand-held Reader/Writer receives a command, it communicates with an RF Tag and then
ST
returns a response.
When the Hand-held Reader/Writer receives a command, it waits to detect an RF Tag in the
SA Antenna's communication area. When the Hand-held Reader/Writer detects an RF Tag, it communi-
cates with the RF Tag and then returns a response.
When the Hand-held Reader/Writer receives a command, it communicates with the RF Tag when
BT
the activate switch is pressed, and then returns a response.
When the Hand-held Reader/Writer receives a command, it waits to detect an RF Tag in the
BA Antenna's communication area after the activate switch is pressed. When the Hand-held Reader/
