NOTICE: An analog output module requires a maximum of 20
milliseconds to perform auto calibration and ranging after it is
reconfigured. During this time span, the module can not be
addressed to perform any other actions.
NOTICE: All configuration parameters can be changed dynamically,
except the checksum and baud rate parameters. They can only
be altered when the INIT* terminal is grounded. (Refer to Baud
rate and Checksum in Chapter 2).

if the command is valid.
?AA(cr) if an invalid parameter was entered or the INIT*
terminal was not grounded when changing baud rate or
checksum settings was attempted.
There is no response if the module detects a syntax or
communication error, or even if the specified address does
not exist.
! delimiter character indicates that a valid command is
received.
? delimiter character indicates that the command is invalid.
AA (range 00-FF) represents the 2-character hexadecimal
address of an analog output module.
(cr) is the terminating character, carriage return (0Dh).
