Fig. 22 Memory bank selection.
The data what you want to write is in “Data”, and “Data Length” means that how many bytes will be
written (see Fig. 23). For example, if you want to write a 96 bits data to EPC bank. The “Data”
must have 12 bytes data, and “Data Length” must be “0x06”. Note that one words is two bytes. After
press “Write” button, the reader will write these bytes to tag, and you will get a status of writing.
Fig. 23 Writing data.
If you press “Lock” button, the reader will lock the tag, and the tag won’t be written anymore. The
“Lock” command is independent of memory bank and data; it just locks the tag anyway.
4.6 GPIO
GPIO panel supports the “Set” and “Get” commands of external I/O. There are one external input and
two external outputs. The check-box is used for the switch between Enable and Disable; the combo-box
is the choice of I/O function. If you want to get the current status of external I/O of reader, click button
“Get Status”. The check-box and combo-box will be related to the current status of reader. In another
way, if you want to set the switch or choice of external I/O of reader, click button “Set Selection” after
choosing what you want. See Fig. 24.
