Config. However, UniConfig is also run on a PC and similarly cannot communicate with the router
until an IP address is entered. Therefore, a connection to the PC running UniConfig needs to be cre-
ated using a serial connection: serial. (See
Serial Control Connections on page 38.)

Control System Expansion Connections
In order to manage two connected NV8288-Plus routers, control system expansion connections
need to be connected between the routers. Expansion control system connections are located on the
rear of the router, as shown in Figure 2-11.
When making control system connections, only one router is directly to the control system. This
router acts as the primary router. When making control system expansion connections, connections
from the remaining router, the secondary router, are made to the primary router. This enables the
router control system to communicate with both routers through the primary router.
There are two control system expansion connections, labeled ‘RTR Expansion’. The ports are
divided into two sets, one primary (‘PRI CTRL’) and one secondary (‘SEC CTRL’). Primary con-
trol is the connection to the primary control card. Secondary control is the connection to the sec-
ondary (optional for redundancy) control card. One port is for primary control (‘PRI CTRL’),
connecting the local router to the control system.
For instructions on making control system expansion connections, see Control System Expansion
Connections on page 40.

Diagnostic Connections
The diagnostic connections enable the router to communicate with the UniConfig application. Uni-
Config runs on a PC separate from the router and is used to perform system setup tasks, and config-
ure and monitor the router. (See
Configuration on page 53.) For information about using
UniConfig, see the UniConfig User’s Guide.
Diagnostic connections connect the router to the PC running the UniConfig application. Two diag-
nostic connections are located on the rear of the router, labeled ‘DIAG’. The ports are divided into
two sets: one primary (‘PRI CTRL’) and one secondary (‘SEC CTRL’), as shown in Figure 2-12.
The primary control connects to the primary control card. The secondary control connects to the
secondary (optional for redundancy) control card.
