ID Sensor Unit Functions
Repeat Auto
With a repeat auto specification, the presence of an RF Tag is automatically detected, and
communications are performed, eliminating the need for detecting the RF Tag as is required for a
trigger specification. As opposed to a single auto specification, command execution is not ended when
communications with the first RF Tag have been completed, rather the ID Sensor Unit waits for the next
RF Tag. Once communications have been completed with a specific RF Tag, communications will not
be performed with it again even if it remains in the interrogation zone. Repeat Auto execution can also
be ended by turning ON the Abort Bit (CIO n, bit 02).
