3. Installation
Making Router Control System Connections
4 If a secondary control card (optional for redundancy) is installed, connect to the ‘CTRL 1’ con-
nection in the ‘SECONDARY CONTROL’ section as described in Step 2 and Step 3. See Con-
trol Cards on page 15.
5 If an alternate control system (e.g., for redundancy or dual control) is being used, make connec-
tions as follows:
a Connect to the ‘CTRL 2’ connection in the ‘PRIMARY CONTROL’ section using a DE9
connector and serial cable.
b Connect the other end of the serial cable to the secondary router control system using a DE9
connector. Wire connectors as described in Step 3.
c Connect to the ‘CTRL 2’ connection in the ‘SECONDARY CONTROL’ section using a
DE9 connector and serial cable.
d Connect the other end of the serial cable to the secondary router control system using a DE9
connector. Wire connectors as described in Step 3.
6 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.
Ethernet Control Connections
Ethernet control connections connect the router to the router control system using Ethernet connec-
tors. Ethernet connections are especially helpful if the PC running the router control system is
going to be on a network. An Ethernet connection is recommended for the NVISION NV9000 con-
trol system.
The Ethernet ports are divided into two sets that communicate with the primary control card or the
secondary control card. For a detailed description of the Ethernet connections, see
Serial Control
Connections on page 11. Unlike serial control connections, there are no Ethernet connections to
redundant control systems because redundant control systems can be connected through Ethernet
network connections.
In order for the router to communicate with the router control system through an Ethernet connec-
tion, an IP address for the router needs to be set in the control card. The IP address is set using Uni-
Config.
The Ethernet control system connections use RJ45 connectors and Cat5, or better, cable. The Ether-
net port is 10/100BT.
