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.
