Making Router Connections
In order for a NV8288, NV8288-Plus or NV8500 Family router to communicate with a SMS7000
system controller, the router must be connected to an EC9535. The router is connected using
the serial control system connections, located on the rear of the EC9535, and a cable provided
by Miranda (WC0152). The proprietary cable is 20 feet (6.096 meters) long with two DE9 (a.k.a.
DB9) connectors on each end for a total of four DE9 connectors.
The serial control ports are divided into two sets that enable the primary control card or the
secondary control card in the EC9535 frame to communicate with the corresponding control
card in the router frame.
How to Make Router Control Connections
1 Locate the serial control connections on the rear of the router, as shown in Figure 2-3. Serial
control connections are labeled ‘PRIMARY CONTROL’ for the primary control card and ‘SEC-
ONDARY CONTROL’ for the secondary control card.
