12.5.6 Tag Inventory Operation
Description:
Executes a tag inventory for all tags of interest. If the selection Criteria and post-
singulation is specified, tags will be partitioned first.
Function Call:
void RFIDInventory(RFID_INVENTORY stInventory, LPACCESS_STATUS
lpAccessStatus, BOOL bBlock = FALSE, int nTimeout = 3000);
Parameters:
stInventory – Inventory operation parameters.
lpAccessStatus - Contain the operation result, use in block mode;
bBlock – Block mode.
nTimeout – Timeout for the access operation, use in block mode.
Returns:
None
12.5.7 Tag Read Operation
Description:
Read one or more 16-bit words from any of a tag's memory banks. While a read may
be used to retrieve a set of tags EPC data, if the EPC is the only desired data,
performing an inventory operation is more efficient. (Read may only be performed on
16-bit word boundaries and for multiples of 16-bit words) if one or more of the memory
words specified by the offset/count combinaion do not exist or are read-locked, the
read from the tag fails.
Function Call:
void RFIDTagRead(RFID_READ stRead, LPACCESS_STATUS lpAccessStatus,
BOOL bBlock = FALSE, int nTimeout = 3000);
void RFIDTagReadEx(RFID_READ_EX stReadEx, LPACCESS_STATUS
lpAccessStatus, BOOL bBlock = FALSE, int nTimeout = 3000);
Parameters:
stRead/stReadEx – read operation parameters
lpAccessStatus - Contain the operation result. Use in block mode;
bBlock - Block mode.
nTimeout - Timeout for the access operation, use in block mode.
Returns:
None
12.5.8 Tag Write Operation
Description:
Write one or more 16-bit words to he specified memory bank. (Write could only
beginning at the specified 16-bit offset. maximum number of 16-bit word to be written
is 8).
If wants to write more than eight 16-bit words data to a tag a one time, please use
RFIDTagWriteEx.
Function Call:
void RFIDTagWrite(RFID_WRITE stWrite, LPACCESS_STATUS lpAccessStatus,
BOOL bBlock = FALSE, int nTimeout = 3000);
void RFIDTagWriteEx(RFID_WRITE_EX stWriteEx, LPACCESS_STATUS
lpAccessStatus, int nTimeout = 3000);
Parameters:
stWrite/stWriteEx – write operation parameters
lpAccessStatus - Contain the operation result. Use in block mode;
bBlock - Block mode.
nTimeout - Timeout for the access operation, use in block mode.
Returns:
None
