to occur based on one or the other reference. For example, ‘VIDEO REF 1’ uses NTSC as a refer-
ence and ‘VIDEO REF 2’ uses PAL as a reference.
“Redundant” or “dual” mode is selected using UniConfig. If “dual” is selected, each output can be
configured individually to use ‘VIDEO REF 1’ or ‘VIDEO REF 2’ as the reference. For more
information, see the UniConfig User’s Guide.

Alarm Connections
The NV5128 provides a system alarm that notifies you of a malfunction, such as when a fan or
power supply is not functioning properly. The alarm connection can be connected to external equip-
ment that display visual signals when an alarm is activated. Creation of external monitoring equip-
ment is outside the scope of this manual. However, basic instructions on wiring the alarm
connections for external monitoring is provided. See
Making Alarm Connections on page 64.
In addition to an alarm connection, the router control system receives status information from the
router’s control card(s). The control cards read the status of the router’s power supply and fans
through the ‘Power Supply Alarm’ connection. The information is then communicated to the router
control system and is viewable using UniConfig. For more information, see the UniConfig User’s
Guide.
A SNMP agent can be installed on the router control system (i.e., NV9000) to communicate power
supply information to a SNMP manager. Installation of SNMP agents and use of SNMP managers
is outside the scope of this User’s Guide.
The router alarm connection is labeled ‘ALARM’, as shown in Figure 2-15 . For instructions on
making alarm connections, see Making Alarm Connections on page 64.
