  • Page 20: Rear Connections

    Module Slots and Rear Connections Rear Connections The rear of the NV8256-Plus (Figure 2-4 on page 10) features a backplate containing BNC connec- tions: 256 for receiving signals and 256 for distributing signals. These connections are passive and pass the signals through to active, receiving connections on the input cards and output cards.

  • Page 21: Router Control System Connections

    Serial Control Connections The NV8256-Plus has four serial ports, as shown in Figure 2-6 on page 11. The ports are divided into two sets, one primary (‘PRIMARY CONTROL’) and one secondary (‘SECONDARY CON- TROL’). Primary control is the connection to the primary control card. Secondary control is the connection to the secondary (optional for redundancy) control card.

  • Page 22: Diagnostic

    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.

    2. Introduction Active Cards The input card receives 16 signals from the local coaxial connectors. Each input is forwarded to an analog-to-digital converter that converts the signals to digital. Each digital input is forwarded to one of 16 distribution amplifiers, which distributes three copies of the signal. One copy is sent to a buffer and then the motherboard, which forwards the signal to the crosspoint card in the left slot (inputs 1–256).

    • One, NV8256-Plus monitor cable (WC0046-00) The NV8256-Plus has a ground lug on the back of the router. Whether to ground or not is optional and failure to connect the ground does not affect normal operation. However, grounding helps pro- tect you and your equipment in case of a power anomaly such as a lightning strike.

    • Setting Redundant Crosspoint Card Switching Overview A router control system is required to use the NV8256-Plus router. The control system provides an interface for operations and maintenance personnel. Through the control system, signal switching can be actively configured, reference inputs selected, partitions for organizing signal switching cre- ated, and certain system functions monitored.
