EZReader HF & EZTune Antenna Installation & User Guide Modes of Operation 37 “I” Do an inventory of tags. Report the UIDs of tags in proximity to the antenna. Once the UID of the tag has been read, it will be in “Quiet” mode until the tag leaves the field of the antenna. The Tag UID is unique number and is programmed during its manufacturer. Many of the bytes in the UID will be non printable with respect to ASCII standard. ACCU-SORT has and assumes no control of these numbers. Note that the bytes of the UID are output in reverse order (the same order that the EZREADER-HF expects the UID in a command). Example ASCII HEX Command STX,I,ETX 02,49,03 Response [Many NP characters] 02,67,5D,83,AD,26,81,07,E0,03
Tag will be in “Quiet” mode until the tag leaves the field of the antenna. To stop the inventory, type “E” (RXHDR and RXTRL is necessary). “L” Lock blocks. There are two available options available: L00bb Locking a block prevents writing data to the specified block. This is a permanent irreversible change to the tag. If the lock is successful, the response will be TXHDR (if any), “YL” (Yes Lock), and TXTRL (if any). The example below is locking block 30 of a tag that is in the antenna’s field. Example ASCII HEX Command STX,L,0,0,3,0,ETX 02,4C,30,30,33,30,03 Response STX,YL,ETX 02,59,4C,5D,03
An unsuccessful lock can reply with any of the following errors: NO TAG COLLMISREAD NL The first three are normal EZREADER-HF error messages, the forth is based on the ISO error flag byte, and probably represents trying to lock a previously locked block. Accu-Sort Systems, Inc.
