B.2 Write protection
DIP switch 5 is used for transmitter write protection. If DIP switch 5 is ON, the transmitter is in write-protect mode and will not accept
write commands. The state of switch 5 may be set before or after power is applied and also at any time during operation of the
transmitter.
B.3 DIP switch states
When power is applied to the transmitter, the application software checks for the states of DIP switches 1 through 5 on the
electronics module. Depending upon the combination of the switches, nonvolatile contents may be transferred from the
measurement assembly to the electronics module (Table 19). Nonvolatile contents will be transferred if, and only if, the write-protect
switch is OFF.

Default settings. Writing to the transmitter is allowed.
SPECIAL NOTE: Clears the nonvolatile memory in the transmitter and reloads the fixed
defaults. It will then copy the current configuration of the electronics module to the
measurement assembly. This should only be used when upgrading a device in which the
software revision is 1.0.1.
Copies nonvolatile content (Factory calibration values and User saved calibration values)
from the measurement assembly to the electronics module. Performed when the
electronics module is replaced in the field.
Copies nonvolatile content from the electronics module to the measurement assembly.
Clears the nonvolatile memory in the transmitter. The fixed defaults will be loaded into the
run time memory.
Writing to the transmitter configuration is not allowed. Editing capabilities using the HMI
will not be present. DIP switches 1-4 are disabled.
