Terminator: 

– Basic  Mode

– Extended Mode

„

Initial. Delay: 

Modulation switch on delay after POR (0 = 192 Tc; 1 = 8192 Tc) 

„

Inverse Data: 

Data uplink is performed inversely when activated (default = not activated)

„

Fast Downlink:

Reduces clock cycles for logical 1/0 detection (default = not activated)

„

OTP: 

Allows a general data protection (default = not activated)

Note:

If the selected settings are not supported by the reader, a warning message is displayed before the config-
uration is executed.

In the Analog Front-End (AFE) Option section, the behavior of the transponder can be influenced in 
terms of damping and modulating during downlink and uplink operation. Selected parameters are sent to 
the transponder by clicking the Write AFE-Option Set Button. Default parameters that are needed for 
Basic Mode are indicated in bold.

„

Lock Block 0: 

Setting this bit locks the whole configuration block of the 

 

transponder. Once locked, the configuration can never be 

 

changed. Use this feature with care.

Note:

Changing the setup of Write Damping or Downlink Protocol has an impact on the write timing. For later 
reconfiguration, if the write timing is not known, configuration will not be possible.
