6 From the Alarm In Polarity tab, select the alarm polarity, the signal that triggers an alarm input.
7 From the Alarm in Duration tab, select Single Frame or Normal Duration. Single Frame
instructs the Intellex to mark a single frame for an alarm event for that alarm input with the
same start and end time. Normal Duration instructs the Intellex to use the duration from the
General tab for an alarm event on the corresponding alarm input.
8 To configure alarm notification via a parallel port:
a select the Parallel Port Event tab. The following screen appears.
b Select Enable Parallel Port event notification. If you deselect this option, the parallel port
acts as a simple parallel port that can be used by parallel port printers.
c Select PIN 2-PIN 9 to signal a device failure event.
Note
The buttons PIN 2 through PIN 9 correspond to the pins (connectors) of the Intellex parallel
port that are used for the hardware event notification. Pins corresponding to the selected
(highlighted) buttons are toggled High during the hardware event, while pins corresponding to
unselected buttons are toggled Low during the same hardware event. Output voltage present
when High is approximately 3.3v. PIN20 and PIN21 are ground connections. Intellex uses the
inverse of the button selections to indicate that no event is pending.
WARNING: Do not enable the Parallel Port Event when a printer or other non-event notification
related device is connected to the parallel port. Enabling Parallel Port event notification while
the parallel port is being used by a printer or other device can damage the Intellex parallel
printer port and the connected printer or device. This feature is recommended for advanced
users only.
