Common Fault Errors
Message Code Cause Solution
FAULT_MSG_WRONG_NUM
BER_OF_DATA
100h If the data length in any of
the messages is less than
or more than the number of
arguments in the message,
the reader returns this
message.
Make sure the number of
arguments matches the data
length.
FAULT_INVALID_OPCODE 101h The opCode received is
invalid or not supported in
the currently running
program (bootloader or
main application) or is not
supported in the current
version of code.
Check the following:
• Make sure the command is
supported in the currently
running program.
• Check the documentation for
the opCode the host sent and
make sure it is correct and
supported.
• Check the previous module
responses for an assert
(0x7F0X) which will reset the
module into the bootloader.
FAULT_UNIMPLEMENTED_
OPCODE
102h Some of the reserved
commands might return
this error code.
This does not mean that
they always will do this
since JADAK reserves the
right to modify those
commands at any time.
Check the documentation for the
opCode the host sent to the
reader and make sure it is
supported.
FAULT_MSG_POWER_TOO
_HIGH
103h A message was sent to set
the read or write power to a
level that is higher than the
current hardware supports.
Check the hardware specifications
for the supported powers and
ensure that the level is not
exceeded. The M6e 1-Watt units
support power from 5 dBm to 30
dBm.
FAULT_MSG_INVALID_FRE
Q_RECEIVED
104h A message was received
by the reader to set the
frequency outside the
supported range.
Make sure the host does not set
the frequency outside this range
or any other locally supported
ranges.
