Setting loop back function
If the MSD sends a communication command back to the MSD itself using the loop back function, the MSD
replies “OK” if processed normally while it replies “NG” if parameter or command is incorrect. (This differs
from reply commands to communication commands received externally; not loop back.) Since “OK” and “NG”
are registered to reply commands 31 and 32 by Factory default, respectively, do not edit or delete those
commands if you use the loop back function and check reply commands.
