Note: It is important to remember that this command, like the download
commands, only affects the volatile copy of parameter data. This volatile
copy of parameter data is not actually copied into non-volatile memory until
the ‘w07’ command is issued.
4.7.4.2 For Non-digitally Compensated 9400 Sensors With Non-volatile Memory
For a non-digitally compensated 9400 sensor with non-volatile memory, the
‘w25’ command applies the same as for non-9400 sensors as far as the
volatile copy of parameter data is concerned. To write parameters into non-
volatile memory, the ‘w08,’ ‘w09,’ and ‘w27’ commands must be used as
described in Section 4.7.6 “Store Parameters Into Non-volatile Memory.”
4.7.5 Configure reset initialization
4.7.5.1 For Non-digitally Compensated 9400 Sensors Without Non-volatile Memory
or Non-9400 Sensors
The module can be configured to retrieve the user-provided parameters out
of non-volatile memory during reset initialization by using the ‘w’ command
with index number 26 and dd=01. If the ‘w26’ command is issued with
dd=00, the factory default parameters will be used, and any user
parameters previously stored in non-volatile memory will be ignored. It is
important to remember that this command only modifies the volatile copy
of this configuration parameter. The configuration parameter is not actually
copied into non-volatile memory until the ‘w07’ command is issued. For
example, to configure the module to retrieve user parameters from non-
volatile memory for third-party sensors during reset initialization, issue
command ‘w2601’ followed by ‘w07.’ (See User’s Manual, Chapter 3,
Set/Do Operating Options (Command ‘w’)). The factory default for this
configuration parameter is for the module to use the user-provided
parameters out of non-volatile memory during reset initialization. The user
parameters are set to the factory default values at time of module
manufacture.
