Configuring Outputs
Clicking an output button (one of 4) displays a “Relay Rule” dialog for the output:
Fig. 6-4: Relay Rule Dialog
In this dialog, you create a Boolean expression involving sources destinations, port status,
and GPI (input) status. When the conditions of the Boolean expression are met (i.e., the
expression is “true”) the relay closes. When the conditions are not met, the relay opens.
Figure 6-4 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; expressions in nested parentheses are evaluated before
those in outer parentheses.
Terms (i.e., operands) are generated by choosing entries in the other fields in this dialog and
clicking ‘ADD’. The example shows the following:
Dest. Device:
MON2
Dest. Level:
SD
Source Device:
CAM1
Source Level:
SD
Choosing these items (and clicking ADD) produces the Boolean sub-expression:
SD on CAM1 is switched to SD on MON2
