ID Sensor Unit Functions
Multi-access Repeat
With a multi-repeat communications specification, the ID Sensor Unit automatically detects multiple RF
Tags that enter the interrogation zone and communicates with them repeatedly when a command is
sent. The ID Sensor Unit sends responses sequentially as communications with the RF Tags in the
interrogation zone are completed. Move the results data stored in the data storage area to another
area before the results data from the next RF Tag is stored. Even after the ID Sensor Unit has sent the
responses, the ID Sensor Unit continues to automatically detect RF Tags that enter the interrogation
zone and communicates with them repeatedly. Operations are prohibited for RF Tags that have
completed communications until they leave the interrogation zone. ID Sensor Unit processing ends
when the Abort Bit is turned ON. The ID Sensor Unit will wait for the next command. (Commands will
be accepted for an Antenna that is not processing a command.)
When using the V680-D2KF @@ /-D @ KF68/V680S-D2KF6 @ with a multi-access repeat specification, the normal
communications speed will be used regardless of the setting in DM m+0.
Multi-access repeat specification cannot be used for communicating with V680-D1KP @@ RF Tags.
