3. Installation
Making Router Control System Connections
3 Connect the other end of the cable to a video reference signal. Be sure the incoming signal is
from a stable source. The signals can be:
PAL
NTSC
Tri-Level Sync (1080i 50/59.94/60 and 720p 50/59.94/60)
4 Connect to the ‘VIDEO REF 2’ input connection, as described in Steps 2 and 3. The reference
can use redundant or dual sources. For more information, see Redundant and Dual References
on page 19.
5 Important: Install a 75 Ω BNC terminator on any unused video reference loop-through con-
nection.
Time Code Reference Signal
The NV5128 does not support a time code reference at this time.
Making Router Control System Connections
To manage signal switching in the NV5128, connections need to be created between the router con-
trol system, UniConfig and the router. UniConfig is an application installed on external hardware
that manages router configuration and set up tasks. For more information, see the UniConfig User’s
Guide.
Connections are as follows:
• Serial control. Use to connect to third-party router control systems requiring a serial control
connection. (See Serial Router Control Connections on page 59.)
• Ethernet. Use to connect to the NV9000 router control system and to create network connec-
tions. (See Ethernet Router Control Connections on page 61.)
• GSC Node Bus. Use to connect to third-party router control systems requiring a GSC Node Bus
connection. (See GSC Node Bus Router Control Connections on page 61.)
The router and the router control system cannot communicate with each other until the port through
which the control system connection is made is initialized. For more information, see the UniCon-
fig User’s Guide.
Serial Router Control Connections
Serial router control connections are used to connect a router to the router control system and are
often used for third-party control systems. Although serial connections can be used for the NV9000
control system, it is recommended that an Ethernet connection is used instead. (See
Ethernet Router
Control Connections on page 61.)
Serial control connections use SMPTE 207M DE9 connectors and serial (RS-422/489) cable. For a
detailed description of the serial control connections, see
Serial Connections on page 17.
