To enter a value in an empty input field, position the cursor anywhere inside the input field
and left-click. You may then enter a value for the new filtering list entry. After entering the
value to add to the list, click the

button.
To add multiple values, click the
Add
button multiple times. Enter all of the new values to
be added, and click the

button. Pressing the Tab key will move between input
fields in ascending order, and Shift+Tab will move between input fields in descending
order.
Clicking the

button. Multiple entries can be removed from the filtering
list by deleting the displayed value in multiple input fields, then clicking the

ZGATE Threshold Filtering Configuration Page
At the top of the Threshold Filtering Configuration page, the filtering mode is displayed as
either Enabled or Disabled. Threshold filtering is only available in select ZGATE devices.
If threshold filtering is not included on your ZGATE device, the filtering mode displayed
on this page will appear as Disabled, and nothing else is shown. Otherwise, the Threshold
Filtering parameters are displayed.
An example of the ZGATE threshold filtering page is shown in Figure 10.
