Connecting The Asi Output; External Alarm System Connector - Cisco D9824 Installation And Configuration Manual

Connecting the ASI Output

Connect the output signal from the D9824 receiver ASI OUT connector.
Use a Belden "Brilliance" cable with foil/braid construction. The shield must
provide 99% or better shielding effectiveness.
The equipment after the D9824 receiver could be a Cisco D9887 HDTV Receiver.

External Alarm System Connector

The D9824 receiver and Alarm relay functionality. See Connecting the Cue Tone/Cue
Trigger Interface (on page 24) for more information on Cue Tone and Cue Trigger
equipment connections. These outputs are user-configurable via the Setup Menu on
the front panel.
The Alarm output connector is a 15-pin sub-D female connector. The following
diagram shows the connector and the pin allocation table for the Alarm output pins.
The connector pin states depend on the selected Relay Mode. The Relay Mode is set
on the front panel via the Main: Setup: Outputs menu.
Changing the Relay Mode for Alarm Monitoring
The Alarm relay is a program relay that can be configured to provide programmed
responses for alarms, warnings, cue trigger states for ad-insertion equipment, or a
cue tone output for connection to ad-insertion equipment. As a default, the Alarm
Relay is configured for Alarm mode.
1 On the front panel menu, go the Main: Setup: Outputs, and select Cueing.
2 Use the down arrow key to scroll through the menu to Relay Mode.
3 Change the state to Alarm and press the Select key to save the new setting. As a
result, the rear panel connector pin states will change to that shown in the table
below for Alarm mode.

Note: A normally closed state implies the state when power is applied to the relay in
a normal operating state, without a trigger or alarm condition present.
