D =
Data String D
The
D=
data string command can be used to store and retrieve up to eight characters in the
EEPROM. This command must have 1 to 8 characters immediately following the ‘=’ character. The
message is terminated with the <cr> (ENTER key) character. The data string is automatically stored
in EEPROM with this action command. Since this string is stored in EEPROM, it will remain in the
PPT even after the power is turned off. Examples include dates for maintenance checks, over/under
range pressure or temperature values, or key pressure readings specific to application. If the re-
sponse has an ‘!’ character instead of ‘=‘, there was an EEPROM parity error.
Note
: This command will not work when a
*ddWE=RAM
continuous write enable is active. It must
be preceded by a singular write enable (
*ddWE
).
Note
: This data can be used to provide the last eight characters of a user provided start-up message
(see the
MO
command). When used as a start-up message, any space character in the
D=
message
will terminate the message. Use an underscore (_) character for spaces.

Your_msg
Your_msg
must have 1 to 8 characters immediately following the ‘=’ character. The message is
terminated with the <cr> character. The legal characters for
Your_msg
include all
characters between the ‘space’ (SP) and lower case ‘z’ inclusive, except the ‘*’, in
standard ASCII (see last page of manual).
