0x00 – apply S0 as Session value;
0x01 – apply S1 as Session value;
0x02 – apply S2 as Session value;
0x03 – apply S3 as Session value;
0xff – apply reader smart configuration (only valid in EPC inventory).
All other values are reserved, reader will return a parameter error status in the response frame if
other value is delivered in this field.
MaskMem (optional parameter): 1 byte, mask area indication.
0x01 – EPC memory;
0x02 – TID memory;
0x03 – User memory.
All other values are reserved, reader will return a parameter error status in the response frame if
other value is delivered in this field.
MaskAdr (optional parameter): 2 bytes, entry bit address of the mask, the valid range of
MaskAdr is 0 ~ 16383.
MaskLen (optional parameter): 1 byte, bit length of mask (unit: bits).
MaskData (optional parameter): mask data. The length of MaskData equals to MaskLen/8. If
MaskLen is not a multiple of 8 integer, the length of MaskData is equal to the int[MaskLen/8]+1.
Non-specified lower significant figures should be filled up with 0.
ReadAdr: 2 bytes, the entry address of target, most-significant byte first. For instance, 0x0000
represent the read operation starts from 1st word (the first 16-bit memory area), 0x0001 represents
operation starts from the 2nd word, etc.
ReadLen: 1 byte, the amount of words to be read in this operation, the minimum length is 1 word
and the maximum is 120 words. 0x00 is not a valid value for this parameter; furthermore the value
of Num should not exceed 120. Reader will return a parameter error status in the response frame if a
0 or a larger than 120 value is delivered in this field.
Pwd: 4 bytes, it is the 4 bytes access password of a tag. From left to right, the first two bytes are the
high bytes of access password, and the last two bytes are the low bytes. The most-significant bit of a
tag 32-bit access password is the most-significant bit in the 1st byte of Pwd (from left to right).
Likewise, the least-significant bit of a tag 32-bit access password is the least-significant bit in the
4th (last) byte of Pwd. Access password will only be used for verification during reserved memory
reading operation, when the associated target memory is password protected and the tag access
password is non-zero. Otherwise Psw should be set to all zero or set to the correct access password.
Target (optional parameter): 1 byte, the Target value of EPC tag inventory.
0x00 – apply A as Target value;
0x01 – apply B as Target value.
All other values are reserved, reader will return a parameter error status in the response frame if
other value is delivered in this field.
