GSC Node Bus Control Connections
Some third-party router control systems require a GSC Node Bus connection. The GSC Node Bus
connection is located on the rear of the router, as shown in Figure 2-8. The NV8256-Plus has one
GSC Node Bus connection, labeled ‘NVISION AUX BUS’. The connection is shared by both the
primary and secondary control card. To use the GSC Node Bus connection, an optional module
must be installed on each control card. For details, contact NVISION. For contact information, see
page iii. For installation instructions, see
GSC Node Bus Control Connections on page 40.

Diagnostic
The diagnostic connections enable the NV8256-Plus to communicate with the UniConfig applica-
tion. UniConfig runs on a PC separate from the router and is used to perform system setup tasks,
and configure and monitor the router. For information about using UniConfig, see the UniConfig
User’s Guide.
Diagnostic connections connect the router to the PC running the UniConfig application. There are
two types of diagnostic connections: temporary and permanent. A temporary diagnostic serial con-
nection is located on the front of each control card. Permanent diagnostic connections are located
on the rear of the router, labeled ‘DIAG’, as shown in Figure 2-9. There are two permanent ‘DIAG’
ports, one primary (‘PRIMARY CONTROL’) and one secondary (‘SECONDARY CONTROL’).
The primary control connects to the primary control card. The secondary control connects to the
secondary (optional for redundancy) control card.
