If more than one HITAG S Transponder is in the field of the antenna a special designed RWD detects the first collision
at the Bit position N = k of the UID response. As a result the RWD starts an Anticollision Sequence (AC SEQUENCE).
This command consists of a 5 Bit number (k4 to k0) describing the physical Bit position k where the collision occurred
followed by (k - 1) Bits of the detected UID and a Bit (one or zero) at the collision position. An 8 Bit CRC (cyclic
redundancy check) of this sequence is also sent to the transponders.
After transmitting this command, all HITAG S Transponders which first k Bits of the own UID match with the k received
UID Bits, answer with the SOF and the rest of their own UID.
If a collision occurs again the described cycle has to be repeated until one valid UID of the transponders in the field is
determined.
The complete response of the HITAG S Transponder is transmitted in Anticollision Coding (AC).
Table 19
During the AC SEQUENCE commands the HITAG S Transponder stays in Init State. Even those HITAG S
Transponders where the k received Bits of the UID do not match remain in Init State.
