Button Definitions
There are two types of buttons in the configuration page: outputs and inputs.
Outputs
Clicking an output button (one of 64 on the left) displays a “Relay Rule” dialog:
In this dialog, you enter a Boolean expression involving sources, destinations, port status, and GPI
status. This sample shows one such Boolean expression.
Boolean expressions comprise terms and operators. The operators include those indicated on the
left:
AND
,
OR
, and
NOT
. Expressions can be parenthesized to control the order of evaluation. Operator
precedence is normally
NOT
>
AND
>
OR
. All parenthesized expressions are evaluated first; nested
parentheses are evaluated before outer parentheses.
Terms (i.e., operands) are generated by choosing entries in the other fields and clicking ADD. The
example shows the following:
