Write Protection Displays a picture of the Electronics module to
demonstrate how to connect the hardware write
protect jumper.
Write Protect Displays the current configuration of the write
protect function. Write Protect is “Yes”(enabled)
if either the write protect jumper on the
electronics board is in the “ON” position or the
firmware write protect has been enabled.
Write Protect On/Off Configure the firmware write protect option.
Write Protect selections are:
“Enable”: enables the firmware write protect
option (changes in configuration parameters will
not be permitted).
“Disable”: disables the firmware write protect
option (requires a password).
A 4-digit password is required to change the
Write Protect option from “Enabled” to “Disabled”
to allow configuration changes. The default
password is “0000”, and can be re-configured by
the user.
Change Password Change the write protect password to a new 4-
digit code.
Tamper Mode Displays the current configuration of the Tamper
detection feature (outside attempts to change
device configuration when Write Protect is
enabled and Tamper Mode is Enabled or Tamper
Mode alone is Enabled).
Refer to the “Tamper
Reporting Logic and Write P
rotect Logic” in Table

Attempt Counter Displays the number of times a tamper attempt
(configuration write) has occurred. This
parameter works as below:
1) The attempt counter will get reset on
following instances:
- When tamper is reset using the
“Reset
Tamper Counter” Method.
- When Tamper Mode is configured. During
the configuration, if the Tamper Mode is
Enabled and the other Tamper
parameters are configured, then that is
also considered as a Tamper Attempt.
2) When tamper attempts are already
incremented, if tamper is reconfigured then
following happens,
- If the reconfigured value is greater than
tamper attempts, then the tamper
attempts value is retained.
If the reconfigured value is smaller than tamper
attempts, then the tamper attempts value is
clamped to the reconfigured attempts.
