• The UniConfig application, installed on a PC, used to perform configuration tasks.
• The system alarm that sends notification of a system failure, such as a fan or power supply mal-
function.
Figure 2-5 shows the system connections. AES3 and Time Code references are not supported at this
time and not discussed in this manual.

Router Control System Connections
Router control systems are usually run on a separate unit (e.g., PC), which is then connected to the
router. The NV8256-Plus provides three different methods for connecting the router to a router con-
trol system: serial, Ethernet or GSC Node Bus. The router control system determines which con-
nection is used. For example, to connect to the NV9000 control system an Ethernet connection is
preferred.
Serial Control Connections
The NV8256-Plus has four serial ports, as shown in Figure 2-6 on page 11. The ports are divided
into two sets, one primary (‘PRIMARY CONTROL’) and one secondary (‘SECONDARY CON-
TROL’). Primary control is the connection to the primary control card. Secondary control is the
connection to the secondary (optional for redundancy) control card. Each set is further divided into
connections that correspond to router control systems: ‘CTRL 1’ corresponds to the primary con-
trol system and ‘CTRL 2’ corresponds to an alternate control system. Using ‘CTRL 2’ connections,
you can connect to an alternate control system (i.e., backup system) or set up dual control, if
desired. For installation instructions, see
Serial Control Connections on page 36.
Serial control ports implement SMPTE 207M tributary.

Ethernet Control Connections
The NV8256-Plus has two Ethernet ports, as shown in Figure 2-7. The ports are divided into two
sets, one primary (‘PRI CTRL’) and one secondary (‘SEC CTRL’). Primary control is the connec-
tion to the primary control card. Secondary control is the connection to the secondary (optional for
redundancy) control card. Each port connects the local router to the control system. Unlike serial
connections, there are no connections to alternate router control systems because you can connect
