Connections
Control Ports
At the top left portion of the rear of the NV5256 frame are 6 DE9 connectors, and further below
that are 2 Ethernet connectors:
S A secondary (router) control card is for redundancy and is not required. If you have an
expanded system (two router frames), make connections only to one frame. The frame to which
you make connections is the “master” frame and it controls the second frame.
Serial Control
The CTRL1 and CTRL2 ports are DE9, female, RS-422. See Control Port Connectors , page 43, for
their pinout information.
You can use these connectors for control using a serial protocol from (1) a primary or secondary
NV9000 router control system, (2) a primary or secondary third-party router control system, or (4)
a router automation system.
Cases:
1 If you are using an NV9000 control system with a serial protocol or if you are using a third-
party control system, connect the primary CTRL1 port to a COM port on the control system’s
server. Similarly connect the secondary CTRL1 port if your router has a secondary control card.
2 If you have a redundant server, connect the primary CTRL2 port to a COM port on the redun-
dant server. Similarly connect the secondary CTRL2 port if your router has a secondary control
card.
3 If you do not have a redundant server, but have an automation system, connect the primary
CTRL2 port to a COM port of the automation system. Similarly connect the secondary CTRL2
port if your router has a secondary control card.
