C=
Data String C
The
C=
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 response 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 first 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
C=
message
will terminate the message. Use an underscore (_) character for spaces.

C=
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).
C K
Check EEPROM
The
C
hec
K
EEPROM command performs a checksum on both the characterization area and the
configuration area of the EEPROM. This check typically takes 180 msec.
Inquiry: *dd
CK
There are four possible responses for this command.
#(or ?)ddCK=
OK
#(or ?)ddCK=
ERR1
#(or ?)ddCK=
ERR2
#(or ?)ddCK=
ERR3
Indicates no checksum errors
Indicates a characterization area checksum error
Indicates a configuration area checksum error
Indicates both checksum errors
