Multi-repeat Mode
In multi-repeat mode, the Controller will wait for ID Tags to come into range after
the command is received. The Controller will continue to communicate with all ID
Tags that come into range. Execute the STOP command to stop the multi-repeat
processing.
Note Do not set the Controller to Energy-saving mode when using the multi-repeat
function.
5-2-6 Selective Access Mode
The Controller will communicate with a particular ID Tag out of the multiple ID
Tags in range of the Antenna. Two commands are needed to use the selective
access function. Use the Tag detect command to allocate temporary ID numbers
to the ID Tags in the communication area and use the Tag specify command to
communicate with a particular ID Tag based on the temporary ID number that
was assigned to it.
Note The Controller must be set to Energy-saving mode when using the selective ac-
cess function.
