Before You Begin
The NK-3G144 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-3G144 supports SMPTE standards 424M, 344M, 259M, and 292M and AES.
Features
The NK-3G144 Routing Switcher provides the following features:
• economical and professional-quality design
• a powerful control system
• support for 3G and multi-definition digital video and AES digital audio
• 10 RU design with slots for duplicate output cards
• control, switching matrix, and power redundancy options
• hot swapping of all boards and power supplies
• smart fan control and monitoring
• enhanced LED indications via the Heartbeat, cards, and power supply
• extensive monitoring via DashBoard
• firmware is fully upgradeable using DashBoard
• fully upgradeable for Carbonite eXtreme (if you have the 2500AR-202-XX frame)
Typical System Equipment
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
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.
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.

12 • Before You Begin RCP Series User Guide (v04)
The NK-IPS and PC with DashBoard are only required for setting up the configuration file and then sending it to
the device. However, you can use the NK Switchboard feature in DashBoard to control and monitor a routing
switcher system.
System Overview
A routing switcher system may use distributed control across the Internet, a LAN, or a VPN. The routing switcher
system shown in Figure 2.1 has been simplified.

How the Panels and Routing Switchers Communicate
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 (see “Connecting a Video Reference to NK Series
Routing Switchers” on page 32).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.
Data Storage
The panel stores information on the menu, destination, level, breakaway, and machine control status. The routing
switcher stores the crosspoint status in its internal memory.
When the system is powered up, the routing switcher restores its crosspoint status. The control panel requests the
status of the routing switcher.

Hardware Overview
This chapter presents information on the NK-3G144 hardware components including the chassis, front and rear
panels, and LEDs.
Front Panel
The front panel of the NK-3G144 Routing Switcher is a hinged door, held in place by a screw and two latches. It
swings open to the left. The Heartbeat LED in the name badge indicates the operational and alarm status of the unit.
Figure 3.1 NK-3G144 — Front Panel
The front panel of the door has a ventilation grill, and behind that, reusable filters. There are two banks of three fans
on the inside of the front panel (see Figure 3.2). The top bank of fans intakes air at the front of the unit, then blows
this over the matrix core and the input cards. Similarly, the bottom bank of fans blows air onto the output cards. The
speed of each fan is monitored and varied as required for the measured temperature of the cards. If the fan is not at
the correct speed, or the temperature of the cards is too high, a fault is indicated.

Figure 3.2 NK-3G144 — Interior of front panel
Chassis
All cards and power supplies are inserted via the front of the routing switcher. All input/output cards and control
cards are inserted vertically into the frame, mating with the motherboard at the rear of the routing switcher. Matrix
cards are inserted horizontally into the frame, mating with the motherboard. The motherboard sits vertically within
the frame, approximately 2 cm in from the rear panel. The motherboard straddles the input, control, matrix, and
output slots, providing connectivity to all boards and power supplies.

Figure 3.3 NK-3G144 — Front View of the Chassis
Cards and Accessories
The NK-3G144 Routing Switcher is expandable from one input card and one output card, up to 18 input cards and
22 output cards. Each card supports eight inputs or outputs.
Standard NK-O3G output cards may be used in slots 15D to 18D. Cards in these slots directly duplicate the outputs
from slots 15 to 18 (outputs 113 to 144). The additional outputs are labelled on the rear panel as 113D to 144D.
These outputs may be used as general-purpose duplicate outputs, or to monitor critical signals that are fed through
outputs 113 to 144.
The control cards set the parameters for the input and output cards, and monitor their operation. The control cards
are functionally responsible for the T-Bus control system, Alarm GPI, and video referencing.
The NK-3G144 has capacity for additional control and matrix cards, which provide redundancy.

The cards may be installed in any of the 18 slots on the left-hand side of the frame (see Figure 3.3). They do not
have to be installed sequentially.
For More Information on...
• installing cards see “Inserting a Card into the NK-3G144” on page 29.
Rear Panel
The rear panel and frame provides a support structure for mounting an input or output BNC rear connector strip.
There are ventilation grills in the rear panel that allow the hot air to escape from the routing switcher.
Each input and output card in the frame must have an input or output BNC rear connector strip connected to the
corresponding position in the rear panel. One of these BNC rear connector strips supports two cards.
For More Information on...
• attaching a BNC rear connector strip, refer to “Attaching a BNC Rear Connector Strip to the Rear Panel of

The control cards are functionally responsible for the T-Bus control system, Alarm GPI, and video referencing.
T-Bus Control System
The T-Bus control system is a multi-drop RS485-based system that supports collision detection and half duplex
communications. It may also be used to provide phantom power to some devices.
Power
The NK-3G144 uses an IEC connector that provides AC mains power to the +15 V DC, 32 A PSU mounted in the
frame. A second IEC connector can be used to install an optional second PSU for redundancy and load sharing.
Alarm GPI
The Alarm GPI is a normally closed relay output. The relay output is open when the frame is powered on and there
are no alarms present.
Conditions that will assert the Alarm GPI output:
