Button Trigger (BT) Communications Specifications
A button trigger (BT) communications specification is used to communicate with an ID Tag when the
antenna is moved close to an ID Tag and the activate switch is pressed after the command has been
sent from the host device.
1. Send the command from the host device to the Hand-held Reader Writer. The operation indicator will
light green.
2. Move the antenna end of the Hand-held Reader Writer close to the ID Tag.
3. Press the Hand-held Reader Writer activate switch.
4. The Hand-held Reader Writer will communicate with the ID Tag.
5. A response is returned to the host device from the Hand-held Reader Writer.
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 acti-
vate switch is pressed, an ID Tag Non-existent Error will occur.
At this time, the operation indicator will flash red.
