AUTOREAD
Subcommand
In this mode, communications with all ID Tags in the communications area can
be made on receipt of the command.
Note In FIFO read/write mode, make sure that multiple ID Tags do not arrive in the
communications area together, otherwise a communications error will result and
further communications will not be possible until there is only a single ID Tag in
the communications area.
In this state, the Controller has no command in process and the Controller is
ready to receive any command other than a subcommand. When a command is
received, the Controller starts processing the command.
After a command is received by the Controller, the Controller ignores the next
command until the Controller processes the command and returns a response.
The Controller, however, accepts the STOP or RESET command anytime.
This is the state in which the Controller has received the POLLING AUTOREAD
command. The Controller is ready to receive the STOP command, RESET com-
mand, or any POLLING subcommand. POLLING subcommands are used for
checking the condition of approaching ID Tags or canceling the POLLING AU-
TOREAD command.
