Making Router Control System Connections
How to Make an Ethernet Connection to the Router Control System
1 Locate the Ethernet connections on the rear of the router, as shown in Figure 3-9. Ethernet con-
trol connections are labeled ‘PRI CTRL’ and ‘SEC CTRL’.
Figure 3-9. Ethernet Connections to Control System (Rear View)
2 Connect to the ‘10/100 BASE T’ Ethernet connection in the ‘PRI CTRL’ section using a RJ45
connector and Cat5, or better, cable.
3 Connect the other end of the cable to an Ethernet hub or switch on the router control system
using a RJ45 connector.
4 If a secondary (optional for redundancy) control card is installed, connect to the ‘10/100 BASE
T’ Ethernet connection in the ‘SEC CTRL’ section as described in Step 2 and Step 3. See Con-
trol Cards on page 15.
5 If two NV8256-Plus routers are being connected together, connect the control system expan-
sion connections. (See Control System Expansion Connections on page 41.)
Or
If the NV8256-Plus is being used as a standalone router, install 50
Ω BNC terminators on the
control system expansion connections. See Terminating Unused Control System Expansion
Connections on page 42.
GSC Node Bus Control Connections
Some third-party router control systems require a GSC Node Bus connection to connect the router
to the router control system. The NV8256-Plus has one GSC Node Bus connection, labeled ‘NVI-
SION AUX BUS’. The connection is shared by both the primary and secondary control cards. For a
detailed description of the GSC Node Bus connection, see
GSC Node Bus Control Connections on
page 12.
To use the GSC Node Bus connection, an optional module must be installed on each control card.
For details, contact NVISION. For contact information, see
Technical Support Contact Information
on page iii.
The GSC Node Bus connection uses 75 Ω BNC connectors and coaxial cable.
