Button Auto (BA) Communications Specifications
A button auto (BA) communication specification is used to execute auto commands after the command
is sent from the host device and the activate switch of the Hand-held Reader/Writer is pressed.
Host device
1. Send the command from the host device to the Hand-held Reader/Writer. The operation indicator will
light green.
2. Press the Hand-held Reader/Writer activate switch.
3. The Hand-held Reader/Writer will enter the communication stand-by state with the RF Tag, and the
operation indicator (LED) will flash green.
If the RF Tag is not detected within one minute of sending the command, a timeout will occur and an RF Tag Non-exis-
tent Error will occur. As a result, the operation indicator will flash red.
4. Communications with the RF Tag will be performed when the antenna end of the Hand-held Reader/
Writer is moved close to an RF Tag.
5. A response is 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.
