    Communications Method Section 5-8 5-8-2-2 Auto Mode In auto mode, after receiving an Auto command from the host, the Reader/Writer waits for a Tag to enter the Antenna’s communications area. Since the Reader/Writer is in a busy state between Auto command reception and the completion of communications with the Tag, it does not accept any commands other than the Stop or Reset Command during the period.

  • Page 115: Repeat Mode

    Other Commands Section 5-8 5-8-2-3 Repeat Mode The Reader/Writer waits for a Tag to enter the R/W Antenna’s communications area. Every time an Tag enters the communications area, the Reader/Writer communicates with the Tag and returns a response. It is not until communications are stopped by the Stop or Reset command that the Reader/Writer accepts the next command.
