Single Auto (SA) Communications Specifications
A single auto (SA) communications specification is used to communicate with an RF Tag when the
antenna end of the Hand-held Reader/Writer is moved close to an RF Tag after the command has
been sent from the host device.
1. Send the command from the host device to the Hand-held Reader/Writer.
2. The Hand-held Reader/Writer will enter the communications stand-by state with the RF Tag, and the
operation indicator (LED) will flash green.
If an 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.
3. Communications with the RF Tag will be performed when the antenna end of the Hand-held Reader/
Writer is moved close to the RF Tag.
4. 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.
