6.3 Anticollision Commands
Family Interrogation
The anticollision commands always have a Family ID and an Anticollision
Index as parameters. These parameters manage the read/writes when multi
-
ple tags are in the same reading field. The Family ID and Anticollision Index
can be used separately or together. If the Family ID is zero, that feature is
disabled, if the Anticollision Index is zero, this feature (and multiple
tag-in-field) is disabled as well.
If both the features are disabled, the commands operate exactly the same as
the Non-Anticollision commands.
Family ID
The Family ID is a 1 byte field in the LRP tag memory at address 0. When
the Family ID parameter is set to zero, the command is broadcast to all the
tags in the field. On the other hand, if it is not equal to zero, only the tags
with the specified Family ID in byte 1will respond to the LRP830.
This feature can help in implementing a multi-level organization of the tags,
by permitting the selective reading of tags by Family ID. This gives faster
access to the tags than by using Anticollision Index alone. As previously
noted, Family ID and the Anticollision Index can be used together for
increased efficiency.
When using the Family ID feature, the first byte of tag memory is reserved,
and thus only 47 bytes are allowed to be used. When the feature is disabled,
48 bytes are available for user data.
For this reason, in the read and write commands, once the parameter Family
ID is not equal to zero, the addresses can go from 1 to 47, and the size from
0 to 47. However, when the Family Code is zero, the addresses can start
from 0, and the size can be up to 48.
In order to initialize a tag with a chosen Family ID, byte 0 in the tag must be
set to that value by means of a Block Write or a Block Write All command.
