The Ross NK-3G Routing Switcher handles high-bandwidth, broadcast-quality, digital video and audio signals, and embedded audio signals. Digital video signals can be 3G, high definition, standard definition, DVB-ASI, or SDTI. The NK-3G supports SMPTE standards 424M, 344M, 259M, and 292M and AES.
Routing switchers may be connected to other NK Series devices via the T-Bus control system to form a multi-level routing switcher system. For smaller routing applications, routing switchers may be used individually to provide switching across a single router level or signal type.
The NK Series of routing switchers may be controlled by:
-An NK Series remote control panel
-The DashBoard NK Switchboard
-An automation system or RS232 terminal, via an NK-SCP/A ASCII/RS232 Control Interface
-The NK-VCP Virtual Control Panel
-The NK-GPI General Purpose Interface
Typical equipment that is used in an NK Series routing switcher system includes:
-Any of the NK Series routing switchers with its appropriate power supply
-An NK-IPS Network Bridge
-An RCP-NK1, RCP-NKM, or RCP-NKQ Remote Control Panel
-A PC running DashBoard, connected via a CAT5 Ethernet cable to the NK-IPS
-Standard source and destination equipment (for example, cameras, VTRs, servers)
If you are connecting the PC directly to the NK-IPS, use a crossover CAT5 Ethernet cable.
If you are connecting the PC indirectly via an Ethernet switch to the NK-IPS, use a straight-through CAT5 Ethernet cable.
DashBoard software may be used to set up each routing switcher via an NK-IPS Network Bridge. These parameters can be saved in a configuration file and sent to a routing switcher at any time using DashBoard.
A routing switcher is a module that switches items of broadcast equipment from a nominated source to a nominated destination. All routing switchers in the system can be connected to other NK Series devices via the T-Bus control system, and can be connected to a video referencing signal. The NK-3G144 can be partitioned. Each partition may be assigned to a unique or common switching level.
Switching
The control panel sends a switch request message to the routing switcher. The routing switcher recognizes the request, sets the crosspoint, then sends a response to the panel.
