GetID
Get_ID (Partial Tag ID)
Table 7-17.
Table 7-18.
When receiving a general GetID command, all tags in the READY state will enter the anticolli-
sion loop and take part in the deterministic arbitration sequence All activated tags will reply
synchronously with the same anticollision response. This specific anticollision signature consists
of a SOF pattern followed by subsequent dual pattern coded Tag ID bit(s) as illustrated in
3-1 on page 10
Table 7-19.
Table 7-20.
Any anticollision loop starts with the interrogator’s GetID command. All tags in the READY state
with a matching partial Tag ID will reply synchronously with their own personal anticollision
response. This consists of an initial SOF pattern followed by the Tag ID bit(s) in dual pattern
coding which continue until the complete Tag ID has been sent or until the tag is eliminated from
the search.
