Making Router Control System Connections
In order for the router control system to communicate with the router, Comm port and Baud rate
information must be entered in each control card using UniConfig. This information is entered
using a temporary diagnostic connection between the router and UniConfig. (See
Temporarily Con-
necting to UniConfig on page 43.) After the information is entered, the router control system con-
nections can “see” the router and the router control system connections can be configured.
Serial Control Connections
Serial control connections are used to connect a router to the router control system. Serial connec-
tions are often used for third-party control systems. Although serial connections can be used for the
NVISION NV9000 control system, it is recommended that an Ethernet connection is used instead.
(See
Ethernet Control Connections on page 39.)
The serial control ports are divided into two sets that communicate with the primary control card or
the secondary control card. Additional ports enable you to connect to an alternate control system
(i.e., backup system) or to set up dual control, if desired. For a detailed description of the serial con-
trol connections, see
Serial Control Connections on page 11.
In order for the router to communicate with the router control system through a serial connection,
Comm port and Baud rate settings need to be set in the control card.
Serial control connections use SMPTE 207M DE9 connectors and serial (RS-422/485) cable.
How to Make Serial Control Connections
1 Locate the serial control connections on the rear of the router, as shown in Figure 3-8. Serial
control connections are labeled ‘PRIMARY CONTROL’ for the primary control card and
‘SECONDARY CONTROL’ for the secondary control card.

2 Connect to the ‘CTRL 1’ connection in the ‘PRIMARY CONTROL’ section using a DE9 con-
nector and serial cable.
3 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:
