4. Operation
Chapter 4 provides general operating information for the NV8256-Plus. It presents the following
topics:
• Overview
• NVISION Control Systems
• Third-Party Control Systems
• Setting Redundant Crosspoint Card Switching
Overview
A router control system is required to use the NV8256-Plus router. The control system provides an
interface for operations and maintenance personnel. Through the control system, signal switching
can be actively configured, reference inputs selected, partitions for organizing signal switching cre-
ated, and certain system functions monitored.
The NV8256-Plus is designed to partner with the NVISION NV9000 control system. However,
NVISION routers are designed with a degree of flexibility and can be used with certain third-party
control systems. For detailed information on using the NVISION NV9000 or NV910 control sys-
tem, see the associated User’s Guide. For information on using third-party control systems, see the
third-party vendor literature. For more information on compatible control systems. For contact
information, contact NVISION. For contact information, see

tion on page iii.
NVISION Control Systems
Most facilities require multi-level switching capability (audio follow video, for example) and intui-
tive device naming capabilities. The control system used dramatically affects how operators use the
NV8256-Plus and the ease with which devices are accessed.
NVISION’s control system (NV9000) runs on a unit (e.g., PC) separate from the router. The router
control system can be loaded on a primary server only, or on both primary and secondary (redun-
dant) servers, creating a fail-over backup. The control system hardware provides control panels for
managing routers and other network equipment.
NVISION’s control systems offer a variety of control surfaces, support redundancy, and facilitate
expansion as routing needs change. The control system is also capable of interfacing with third-
party signal routing equipment. Because of the variety of features, capabilities and limitations of
other manufacturers’ equipment, users are urged to work closely with NVISION’s technical staff
and with the supplier of the third-party equipment when integrating it into an NV9000 control sys-
tem.
