The GPIO Section of the NV9641A Page
SE’s NV9641A configuration page provides a GPIO section, below the tree window:
Click on a button under ‘Outputs’ to configure one of the 4 tally outputs.
Click on a button under ‘Inputs’ to configure one of the 8 tally inputs.
There are no actual GPIO
buttons
on the NV9641A control panel.
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.
