Not released in Basic Mode:
Terminator:
–Basic Mode Sequence Terminator
– Extended Mode Sequence Start Marker Terminator
Initial. Delay: Modulation switch on delay after POR (0 = 192 Tc; 1 = 8192 Tc)
Inverse Data: Data up link 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.
5.3.6.3.2 AFE Option Setup:
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.
Clamp Voltage: Clamp Low, Clamp Medium, Clamp High
Soft Modulation No Soft Modulation, One Pulse Weak, One Pulse Strong, Two
Pulses, Smooth
Gap Detection Threshold Low, Medium, High
Clock Detection Threshold Low, Medium, High
Modulation Voltage Modulation Low, Modulation Medium, Modulation High
Modulation Delay No Delay, One Pulse Delay, Two Pulses Delay
Write Damping WD and Low Attenuation, WD and High Attenuation, Low
Attenuation, High Attenuation, WD Only, OFF
Downlink Protocol Fixed Bit Length, Long Leading Ref, Leading Zero Ref, 1of 4
Coding Ref
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 ti ming. For later
reconfiguration, if the write timing is not known, configuration will not be possible.
