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.

D_OPCODE
102h
Some of the reserved

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_T

REQ_RECEIVED
104h
A message was received by
the reader to set the
