•
Field interference on the reader
The reader is receiving interference from its environment.
–
External interference field; the field of interference can be verified with the "inductive field
indicator" of the STG
–
The distance between two readers is too short and does not correspond to the configuration
guidelines
–
The connecting cable to the reader is disrupted, too long or does not comply with the
specification
–
MOBY U: Transponder has left the antenna field during communication.
–
MOBY U: Communication between reader and transponder was aborted due to a disruption
(e.g. person/foreign body moving between reader and transponder).
•
Too many transmission errors
The transponder could not receive the command or the write data correctly from the
communications module 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 error 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 acknowledgement 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 area of the transmission window
–
The transponder is using too much current (defect)
–
Bad FORMAT parameter setting for transponder EEPROM
•
RF600:
–
No free ETSI channel
–
Wrong communications standard selected in the "init_run" command
–
Bad expert parameter
–
Power check of the ETSI wireless profile is incorrect

•
More transponders are located in the transmission window than can be processed at the same
time by the reader.
•
RF600: Transponder power supply close to limit.
Increase the antenna power or reduce the distance to the transponder.
