Single Auto (SA) Communications Specifications
A single auto (SA) communications specification is used to communicate with an ID Tag when the
antenna end of the Hand-held Reader Writer is moved close to an ID 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 ID Tag, and the
operation indicator (LED) will flash green.
If an ID Tag is not detected within one minute of sending the command, a timeout will occur and an ID Tag Non-existent
Error will occur. As a result, the operation indicator will flash red.
3. Communications with the ID Tag will be performed when the antenna end of the Hand-held Reader
Writer is moved close to the ID 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.
