1. The host sends the POLLING AUTO command to node 1.
2. After the command is received, the Controller returns a response to the host
indicating the acceptance of the command.
3. The host sends the POLLING AUTO command to node 2.
4. After the command is received, the Controller returns a response to the host
indicating the acceptance of the command.
5. The host can use subcommands to check the process of command execu-
tion or cancel the execution of the POLLING AUTO processing. If the ID Tag
has not approached yet, a response indicating the status is sent in reply to
an inquiring subcommand.
6. When the ID Tag passes through the communications area of node 1's An-
tenna, communication is established.
7. If a subcommand is sent for confirmation to the Controller that has finished
processing communications with the ID Tag, the Controller will return a re-
sponse of a process result.
