PIN code has a length of 4 bytes. Type in the fields Word11 and Word10 any value you want. Click buttons Write opposite to those fields. Now the PIN code is stored into a transponder.
The next step may be "transponder locking". This operation is reversible only if you know the PIN code. To lock the transponder you have to set the "lock bit" of the transponder located in the Word1, leftmost byte. Type "E0 XX" in the Word1 field and click the Write button opposite to this field. After operation completed click the Read button, now the Word1 content will be displayed in red color that means that the transponder is locked.
To unlock transponder click the "Unlock (using PIN)" button. Be shure that fields Word11 and Word10 show the correct PIN code.
The PIN operations are described in the video tutorial file of the main help of the Tango.
