Before writing data to tag or locking the tag, you must turn on the RF power. Different with reading,
the antenna setting is just the Tx selection. Choose one Tx antenna which you want to use to write
the tag (see Fig. 21). You can also adjust power like reading.
Fig. 21 Antenna selection and power adjuster.
In writing, there are two banks that can be written – User & EPC. You can select what bank you want
to write by change “Memory Bank” (see Fig. 22).
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.
