Distinguished Tag Read/Write Function

3-6
The V720-series Tag has two Tag classification codes: Family code and
application ID. Each code consists of 1 byte of data. Communications can be
limited to Tags that match the two codes. This is called the Distinguished Tag
Read/Write Function.
For how to set and change the Tag identification code, refer to Read of
Application ID and Family Code (for Tag) and Write of Application ID and
Family Code (for Tag), 5-3-6 System Commands and Responses.
For setting and changing ID codes included in commands sent from the
Antenna, refer to (5) Setting of Family Code (for Controller)(FC) and (6)
Setting of Application ID (for Controller)(AI), 5-3-6 System Commands and
Responses (for ID Controller). The factory setting for the Controller's ID code
is 00h for both family code and application ID. This permits communications
regardless of the Tag's codes.

Application Example
For the Controller settings given in 1), communications are possible with all
the Tags because the codes set in the Controller are both 00 hexadecimal.
For the settings in 2), communications are possible only with the A and B
Tags, which have the specified family code. Communications are not
possible with Tag C. For the settings in 3), communications are possible only
with the A Tag, which has both the same family code and the same
application ID. Communications with Tag B and Tag C are not possible.
