ION Meter Security
Any configuration changes sent to the meter through its communications ports or
its front panel must be validated with the meter’s password (in addition to your
ION software password) before the change is set on the meter.
The Meter Password
The meter password is a numeric string of up to eight digits. If Standard security
is enabled, the meter password is required when you attempt to make a change to
the meter configuration through the front panel or using software such as Vista,
Designer, Device Upgrader or ION Setup.
NOTE
The Front Panel Programming setup register in the Display Options module lets you lock out any changes
through the front panel. You can set this register using Designer or ION Setup software.
Standard Meter Security
Standard meter security is enabled by default on all ION meters; all configuration
functions in the front panel are password-protected. The password is factory-set to
0 (zero).
If you make configuration changes to the meter via the front panel, the meter
prompts you for its password before accepting any configuration changes.
Similarly, if you make any configuration changes via ION software you are
prompted by the meter for its password (in addition to the password used to
access ION software). Once you enter the correct meter password and confirm the
new configuration, the change is set on the meter.
Note that the front panel will prompt you for the meter password before you make
your first configuration change. You will not need to re-enter the password for
each subsequent change. However, if you perform no additional configuration
changes for five minutes, you will need to re-enter the Setup menu and provide the
valid meter password to resume making changes. This is because the meter returns
from setup mode to data display mode after five minutes of inactivity.
