4.7.5.2 For Non-digitally Compensated 9400 Sensors with Non-volatile Memory

Non-digitally compensated 9400 sensors with non-volatile memory are

not affected by the ‘w26’ command. The module will always use sensor

EEPROM data, if available.

4.7.6 Store parameters into non-volatile memory

4.7.6.1 For Non-digitally Compensated 9400 Sensors without Non-volatile Memory

or Non-9400 Sensors

All of the above commands download data into volatile memory. If the

module is reset, the effects of the commands will be lost unless the ‘w07’

command is issued prior to module reset. The ‘w07’ command is used to

copy all of the parameters from volatile to non-volatile memory.

4.7.6.2 For Non-digitally Compensated 9400 Sensors with Non-volatile Memory

Non-digitally compensated 9400 sensors with non-volatile memory are

not affected by the ‘w07’ command. Sensor offset and gain terms are

downloaded into sensor non-volatile memory using ‘w08’ and ‘w09’

commands, respectively. Coefficients c0 through c3 are downloaded into

sensor non-volatile memory using the ‘w27’ command. The ‘w27’

command can use an optional position field to make the action

channel-specific. For example, ‘w2700 0801’ will perform the download

for channels 12 and 1.

User-defined data, manufacturing reference number, full-scale range code,

and front-end gain are downloaded immediately into sensor non-volatile

memory as a result of the ‘v’ command (together with the associated index

number for each parameter).
