2. Installation
Making Router Control System Connections
5 Connect the other end of the serial cable to the (primary) router control system using a DE9
connector. The following lists the pin wiring for the DE9 connectors:
6 If a secondary control card (optional for redundancy; see Serial Connections on page 16) is
installed, connect to the ‘CTRL 1’ connection in the ‘SEC CTRL’ section as described in Step 2
and Step 3.
7 If an alternate router control system (e.g., for redundancy or dual control) is being used, make
connections as follows:
a Connect to the ‘CTRL 2’ connection in the ‘PRI CTRL’ 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, wiring the connector as described in Step 3.
c Connect to the ‘CTRL 2’ connection in the ‘SEC CTRL’ 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, wiring the connector as described in Step 3.
8 If two NV7512 routers are being connected together, connect the control system expansion con-
nections. See Router Control System Expansion Connections on page 61.
Or
If the NV7512 is being used as a standalone router, install 50
Ω BNC terminators on the control
system expansion connections.
Ethernet Router Control Connections
Ethernet router control connections connect the router to the router control system using Ethernet
connectors. Ethernet connections are 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 router control
system. The Ethernet ports are shared by the primary and secondary control cards. For a detailed
description of the Ethernet connections, see
System Connections on page 15.
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. For more information, see the
UniConfig User’s Guide.
The Ethernet connections use RJ-45 connectors and CAT5, or better, cable. The Ethernet port is 10/
100baseT.
