External Alarm System Connector
The D9854/D9854-I receiver and Alarm relay functionality. See Cue Tone/Cue
Trigger Interface (on page 36) 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 A larm 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 to 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.
Connecting the RS-232 Data Interface
The DCE DB-9 female connector is intended for low-speed data: 7 bits, even parity, 1
stop bit, up to 38.4 kb/s (default). These outputs are user-configurable via the Setup
Menu on the front panel.
The interconnect cable from the D9854/D9854-I receiver to a PC should be straight
through (for example, no handshaking), shielded and equipped with a DB-9 male
connector at one end to mate with the rear panel RS-232 Data interface, and a female
DB-9 connector to connect to the PC.
