13. Modes
13.1 Anticollision
The RWD is the master of the communication with one or multiple transponder ICs. It
starts the anticollision sequence by issuing the inventory request (see
Section 14.3
).
Within the RWD command the NOS flag must be set to the desired setting (1 or 16 slots)
and add the mask length and the mask value after the command field.
The mask length n indicates the number of significant bits of the mask value. It can have
any value between 0 and 44 when 16 slots are used and any value between 0 and 48
when 1 slot is used.
The next two subsections summarize the actions done by the transponder IC during an
inventory round.
13.1.1
Anticollision with 1 slot
The transponder IC will receive one ore more inventory commands with NOS = '1'. Every
time the transponder ICs fractional or whole UII matches the mask value of RWD's
request it responses with remaining UII without mask value.
Transponder ICs responses are modulated by dual pattern data coding as described in
Section 10.2
.
13.1.2
Anticollision with 16 slots
The transponder IC will receive several inventory commands with NOS = '0' defining an
amount of 16 slots. Within the request there is the mask specified by length and value
(sent LSB first).
In case of mask length = '0' the four least significant bits of transponder ICs UII become
the starting value of transponder IC's slot counter.
In case of mask length
≠
'0' the received fractional mask is compared to transponder IC's
UII. If it matches the starting value for transponder IC's slot number will be calculated.
Starting at last significant bit of the sent mask the next four less significant bits of UII are
used for this value. At the same time transponder IC's slot counter is reset to '0'.
Now the RWD begins its anticollision algorithm. Every time the transponder IC receives an
EOF it increments slot-counter. Now if mask value and slot-counter value are matching
the transponder IC responses with the remaining UII without mask value but with slot
number
In case of collision within one slot the RWD changes the mask value and starts again
running its algorithm.
