Making Router Control System Connections
(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 12.
Serial control connections use SMPTE 207M DE9 connectors (RS-422/489) and serial cable.
How to Make Serial Control Connections
1 Locate the serial control connections on the rear of the router, as shown in Figure 3-13. Serial
control connections are labeled ‘PRI CTRL’ and ‘SEC CTRL’.
Figure 3-13. Serial Control Connections to Control System (Rear View)
2 Connect to the ‘CTRL 1’ connection in the ‘PRI CTRL’ section using a DE9 connector and
serial cable.
3 Connect the other end of the cable to the (primary) router control system using a DE9 connec-
tor. The following is a list of DE9 wiring for the connectors:
4 If a secondary (optional for redundancy, see Control Cards on page 15) control card is installed,
connect to the ‘CTRL 1’ connection in the ‘SEC CTRL’ section as described in steps 2 and 3.
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 ‘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. Wire connectors as described in Step 3.
c If a secondary (optional for redundancy; see Control Cards on page 15) control card is
installed, connect to the ‘CTRL 2’ connection in the ‘SEC CTRL’ section using a DE9 con-
nector and serial cable as described in steps 5a and 5b.
6 If connecting two NV8288-Plus routers together, connect the control system expansion connec-
tions. (See Control System Expansion Connections on page 40.)
