TMEB8704 Application Note
Note:
To change the Configuration Setup, click the Configure Transponder button to program the con-
figuration block of the transponder. (The transponder should be placed close to the application
board antenna.)
Use Read Timing on the right side to set the timing parameters for decoding. Under normal
operating conditions, the default values can be used.
To read out the transponder, click the Read button. The decoding principle, in simple terms, is to
send the chosen Configuration and Read Timing to the microcontroller on the RFID application
kit. Using real-time analysis, the incoming data stream is decoded to binary values and then sent
to the PC. Clicking on the button Default restores the default setting. The Stop Transpon-
der-Modulation button sends the stop command to the transponder. (This halts modulation until
POR.) To leave the TK5561 user interface, click on the Cancel button. Clicking the Direct
Access... button makes blockwise reading possible.
Figure 5-12. TK5561 Read Tab
• Coding: Manchester and Bi-phase
• ID-code length: 64 bit or 128 bit
• Signature: Header, Terminator 1 and Terminator 2
• Password: Activates password mode
• Enable Stop-mode: Obey stop command
• Lock Block 0:
• AUT64 rounds: Number of AUT64-times
• Auto adapt: Automatic (ON) or user-programmed adapt bit setting (OFF)
Setting this bit locks the configuration block of the transponder. This means bit rate, coding,
etc. are fixed and cannot be changed anymore. Please use this feature with care.
The U2270B is not able to read all bit rates and coding types displayed. If a transponder is config-
ured in an invalid mode, a warning message will be displayed. For details, please refer to the
e5561 datasheet.
