To read out the transponder, click Read. The decoding principle, in simple terms, is to send the
chosen Configuration and Read Timing to the microcontroller on the RFID application kit. In a
real-time analysis, the incoming data stream is decoded to binary values and then sent to the
PC. Clicking the button Default restores the default setting. Clicking the Stop Transponder-Mod-
ulation button sends the stop command to the transponder. (This disables modulation until the
transponder receives a POR or AOR wake-up command.) To leave the TK5551 user interface,
click Cancel. Click Direct Access..., to do blockwise reading. Make sure that the right Header for
the chosen block is typed into the header text field. If Sequence Terminator is activated, only
Block 0 and the Maxblock are readable (for example, Block 1 to 5 is configured, then Block 5 is
also readable with Direct Access....).
Figure 5-9.
TK5551 Write Tab
When the Write tab is selected, the Write Setup and Write Timing are shown. The first byte in
Block 1, the header byte, is adjusted in the header text field of the Read tab. The password box
is the same as in the configuration setup. When the Password box is selected, Block 7 changes
to password.
Use Write Timing on the right side to set the timing parameters for writing. Under normal operat-
ing conditions, the default values can be used.
The programming of the transponder is performed by clicking Program Transponder. The data
for each block is entered using hexadecimal code (characters 0 to 9 and A to F). The blocks to
be programmed are selected by selecting the corresponding check box in the Write column. To
protect the data from being overwritten, the lock bit feature can be used. Once set, the informa-
tion cannot be overwritten. (Please use this feature with care.) Default restores the default
setting. To leave the TK5551 user interface, click Cancel.
