Description
•
b110 = Read request without ISO 15693-specific data check and ISO 15693 data interpreta-
tion
Response is queried after CMD-RES-DELAY.
Because there is no data check in the reader, all data with the same response length as the
response length transferred to the reader in the host command is transferred with the status
0x00. If the response length of the data from the transponder and the response length speci-
fied for the reader in the host command are different, the reader responds with the status 0x01
"no transponder".
The user of command mode 6 must control the data encryption and decryption option of the
reader using CFG4/byte 4 – ISO mode so that the reader encrypts the data in the RF forward
connection and decrypts in the RF backward connection.
TxCR
CEn
•
b0 a checksum is calculated over the sent data and the CRC byte(s) is/are appended to the
data stream.
•
b1 no checksum is inserted/sent.
RSP-
LENGTH
Length of the transponder response in bits without SOF and EOF. If the error flag is set in the transponder
response, the length of the read out data is 4 bytes.
CMD-RSP-
DELAY
Response delay of the transponder response (ISO15693: T1) e.g. ISO 15693 average value: {0x021F} ×
590 ns = 320.4
μs
If the parameter is set to "0x0000", the default value 0x021F is used.
EOF-PULSE-
DELAY
The EOF pulse delay is used with write operations with the ISO 15693 write option "1". It is used to specify
the response delay of the transponder response (ISO 15693: T1). e.g. ISO 15693 maximum value:
{0x846A} × 590 ns = 20 ms
REQUEST-
DATA
Full transponder query without SOF, CRC16 and EOF
The FLAGS for the read and write options in REQUEST-DATA must match the MODE byte in the query
protocol. The reader always forces a command in the way specified in the MODE byte of the query proto-
col.
RESPONSE-
DATA
Full transponder resonse without SOF and EOF. The reader runs a CRC 16 checksum test. The CRC16 of
the transponder is, however, transferred with the response data.
Data is only transferred if STATUS = {0x00, 0x02, 0x83, 0x84, 0x94}.
The response data always consists of the number of data bytes specified in RSP-LENGTH.
