AutoRun ON, continuous operation:
An ASI frame + n BFR frame(s) is sent.
- ASI frame format:
<ASI><IMC><RF_Auto_Run><current operating mode number><Success flag>
0x03 0x0A 0x10 0xnn partial success = 0; complete success = 1
(current “RFID operating mode selection” and success flag are defined in the “RFID
Auto Configuration Commands” on page 4-46).
(“Success flag” indicates if the data obtained corresponds to a complete success or
partial success with a read/write status to check which data is valid. With complete
success, the read/write status of the BFR frame is always set to the value 0xFF)
After each success, a BFR frame is sent to the host.
- n BFR frames corresponding to the identified tags are sent under the following format
each time that a new tag is identified:
<BFR><[Preamble]><AIM_ID><Read/Write status><Tag_ID><[Data]><[Postamble]>
AutoRun OFF:
An ACC frame is sent after the AutoRun function is stopped.
- ACC frame format: <ACC>
AutoRun ON + time-out:
An ASI frame is sent:
- ASI frame format:
<ASI><IMC><RF_Auto_Run ><current operating mode number ><success flag>
After each success, a BFR frame is sent to the host.
- n BFR frames corresponding to the tags identified during the session are sent with the
following format:
<BFR><[Preamble]><AIM_ID><Read/Write status><Tag_ID><[Data]><[Postamble]>
When the time-out expires, a PEV frame (Product EVent) is sent.
- PEV frame format: <PEV>< Event number>
with event number = RF_Auto_Run_Timeout (0x20)
Read status is represented by the low nibble of the Read/Write status byte [b3 - b0].
Each bit is a flag indicator of successful Auto Read operation, bit 0 corresponds to field
1, bit 3 corresponds to field 4. If a field bit is not set and the corresponding field is
activated, this means that the data of this field is incorrect.
Write status is represented by the high nibble of the Read/Write status byte [b7 - b4].
Each bit is a flag indicator of successful Auto Write operation, bit 4 corresponds to field
1, bit 7 corresponds to field 4. If a field bit is not set and the corresponding field is
activated, this means that the data of this field is incorrect.
For example, if you have selected 3 read fields (1, 2, 3) and the read status is 0x05
(0101), this indicates that field 2 is invalid (the data for field 2 will be included in the data
response but will not be valid).
