Module will communicate with Tag immediately after receiving command
and transmit response. After communication is completed, Module will
prohibit Tag from operating. Module will be on stand by for commands after
response is transmitted. During communication with Tag, there MUST BE
AN OPERATIONAL TAG (A TAG THAT IS NOT PROHIBITED FROM
OPERATION) within the communication area. When this command is
executed, Module automatically activates "Oscillation Mode"
♦ Operation Sequence
Upon receiving command, Module will execute process once only. If there
is no Tag, a Tag absence error will be transmitted. During processing of the
command, Tag will become inoperative, and thus will not respond to the
next command. Oscillation will continue after command is processed.
