Error description
Field disturbance on reader
Possible causes:
•
The reader is receiving interference pulses from the environment.
External interference field. The interference field can be detected with the "inductive field
–
indicator" of the mobile reader.
The distance between two readers is too small and does not correspond to the
–
configuration guidelines.
The connecting cable to the reader is defective or too long or does not comply with the
–
specification.
•
Too many transmit errors
The transponder was unable to receive the command or the write data from the
communication module correctly even after several attempts.
The transponder is positioned exactly in the limit area of the transmission window.
–
Data transmission to the transponder is being affected by external interference.
–
•
CRC sending error
The transponder reports CRC errors frequently (transponder is positioned in the limit area
–
of the reader; transponder and/or reader has a hardware defect).
•
Only during initialization: CRC error on receipt of acknowledgment from transponder (cause as
for field interference on the reader).
•
When formatting, the transponder must be in the transmission window of the reader,
otherwise a timeout error will occur, in other words:
The transponder is located exactly in the limit range of the transmission window.
–
The transponder is defective and consumes too much power.
–
The EEPROM transponder was incorrectly configured by "FORMAT".
–
•
RF300: ECC error
The data cannot be read from the transponder.
Possible causes:
Transponder data has been lost (transponder defective).
–
The transponder was not initialized with the ECC driver.
–
The EEPROM memory of the transponder has reached its end of life and the data has been
–
lost.
The transponder left the antenna field during the write operation.
–
The command to the communications module was issued incorrectly.
–
•
RF600:
No ETSI channel is available.
–
An incorrect communication standard was selected in the "INIT" command.
–
The expert parameter is incorrect.
–
The performance check of the ETSI radio profile is faulty.
–
•
Freeport: Negative acknowledgment or bad frame from the reader
•
More transponders are located in the transmission window than can be processed at the same
time by the reader.
•
There is more than one transponder in the transmission window.
