Get all EPCs
To read a tag in this menu, the Get all EPCs button must be clicked once the reader has been correctly
configured. The reader now tries once again to read all the tags in the field of the selected antenna. If in the
Antenna selection drop-down menu the number of antennas has been restricted, reading will now be
performed using the currently selected antenna, or using the antenna selected with All in the Expert
settings 1.
The EPCs from the tags read successfully are displayed in the field below. For the following operations, a tag
can be selected from this list by clicking on it.
Write EPC
The EPC of the tag can be modified. For this purpose an EPC in hexadecimal format must be entered in the
New EPC field.
Note: Comply with the maximum EPC length supported by the tag - if this is exceeded the tag will return an
error.
If the requirement is only to amend an existing tag, this tag can be loaded to the field by pressing the Apply
selected EPC button. Now the EPC can be changed manually, or by using the Auto increment option 
increased by one at each write event.
The write event itself can optionally be executed on this tag by pressing the Write EPC to selected tag
button. At this time there may be several tags in the field, but at least one tag from the list must be selected.
The second option is to write the specified EPC without a tag being selected. When using this function, make
sure there is just one single tag in the field.
Change password
The EPC standard specifies that the tag should have two modes, the open and the secured state. In the
open state, operations can be performed on the tag if the associated memory areas are not secured with a
password greater than 0. If a password has been set and the Lock section (bottom of the Test Gen2
functions tab) of the GUI has been used to set the memory areas to password protected, the desired
operation will not be executed and the tag will report an access error. Normal access remains available in
areas that are not blocked.
On access with the valid password, the tag switches into the secured state and access is available even in
blocked areas. Setting the password and setting how individual areas are blocked is performed under the
Change password and Lock section of the SW.
Under the first section the password for restricting access to the tag and the password for deactivation of the
tag are set. The access password can be used to restrict access to the tag in the open state. Depending on
the configuration under the Lock section, parts of the tag can be provided with completely or partially
restricted access rights.
The deactivation password is required to deactivate the tag permanently by means of a Kill command.
