FAULT_AHAL_INVALID_F
REQ
500h
A command was received to
set a frequency outside the
specified range.
Check the values you are trying to
set and be sure that they fall
within the range of the set region
of operation.
FAULT_AHAL_CHANNEL
_OCCUPIED
501h
With LBT enabled an attempt
was made to set the
frequency to an occupied
channel.
Try a different channel. If
supported by the region of
operation turn LBT off.
FAULT_AHAL_TRANSMIT
TER_ON
502h
Checking antenna status
while CW is on is not allowed.
Do not perform antenna checking
when CW is turned on.
FAULT_ANTENNA_NOT_
CONNECTED
503h
An attempt was made to
transmit on an antenna which
did not pass the antenna
detection when antenna
detection was turned on.
Connect a detectable antenna
(antenna must have some DC
resistance).
FAULT_TEMPERATURE_
EXCEED_LIMITS
504h
The module has exceeded the
maximum or minimum
operating temperature and will
not allow an RF operation until
it is back in range.
Take steps to resolve thermal
issues with module:
• Reduce duty cycle
• Add heat sink
FAULT_POOR_RETURN_
LOSS
505h
The module has detected a
poor return loss and has
ended RF operation to avoid
module damage.
Take steps to resolve high return
loss on receiver:
• Make sure antenna VSWR is
within module specifications
• Make sure antennas are
correctly attached before
transmitting
• Check environment to ensure
no occurrences of high signal
reflection back at antennas.
FAULT_AHAL_INVALID_A
NTENA_CONFIG
507h
An attempt to set an antenna
configuration that is not valid.
Use the correct antenna setting or
change the reader configuration.
Tag ID Buffer Fault Errors

Solution
FAULT_TAG_ID_BUFFER
_NOT_ENOUGH_TAGS_
AVAILABLE
600h
A command was received to
get a certain number of tag ids
from the tag id buffer. The
reader contains less tag ids
stored in its tag id buffer than
the number the host is
sending.
Send a test case reproducing the
behavior to rfid-
[e-mail].
