SelectGroup
When receiving the SelectGroup command, all tags in the READY state with the matching par-
tial Tag ID will enter the Selected state and answer with the SOF pattern. The partial Tag ID can
vary in length. It’s pattern position relative to the Tag ID is set by the first (leftmost)
1
in the com-
mand parameter. The preceeding
0
bits act solely as “don’t care” spacer bits. This “mask
header” is not part of the actual partial Tag ID. The mask pattern follows the mask header and is
terminated by the end of command.
Leading
0
don’t care mask bits +
1
= mask header (not part of Partial Tag ID)
X
= don’t care mask bits
Example of SelectGroup Parameters:
Sample Tag ID 6CB9 :
01 10 11 00 10 11 10 01
