Communications with the ID Tag
There are four types of communications specifications for communicating with ID Tags using the Hand-
held Reader Writer.
Single Trigger (ST) Communications Specifications
After the antenna end of the Hand-held Reader Writer has been moved close to an ID Tag, a single
trigger (ST) communications specification is sent from the host device to communicate with the ID Tag.
1. Move the antenna end of the Hand-held Reader Writer close to the ID 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 ID 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 ID Tag is not detected within the Hand-held Reader Writer's communication area when the com-
mand is sent from the host device, an ID Tag Non-existent Error will occur. At this time, the operation
indicator will flash red.
