Making Router Control System Connections
To manage signal switching in the NV8256-Plus, connections need to be created between the router
control system and the router.
Connections are as follows:
• Serial Control — use to connect to a third-party router control system requiring serial control
connections.
• Ethernet Control — use to connect to the NVISION NV9000 router control system and to create
network connections.
• NVISION Aux Bus — use to connect to a third-party router control system requiring a GSC
Node Bus connection.
If connecting two NV8256-Plus routers together, only one router is directly connected to the router
control system. This router acts as the primary router. Additional control system expansion connec-
tions are then made between the primary router and the secondary, connected router. This enables
the router control system to communicate with both routers. (See
Control System Expansion Con-
nections on page 41.)
