The maritime industry relies on KVM technology for a range of applications—from the engine room to the wheelhouse. Given the unique challenges of operating in a marine environment, ensuring the security, quality and reliability of mission-critical navigation and communication systems is essential. The international standard IEC 60945 certifies that equipment has passed stringent tests on security, the operating environment and electromagnetic compatibility. Ultimately, IEC 60945 determines what equipment can be installed on a ship or bridge area. Choosing products that are pre-certified can help you stay compliant.
KVM for maritime applications
Vessels that use KVM technology include personal watercrafts, military vessels, dredgers, luxury cruise liners and sea freight containers. Regardless of the type of craft, KVM matrix switches can operate hundreds of computers over one or more consoles. KVM Multiview enables simultaneous monitoring and management of multiple computers.
KVM technology can optimize IT installations, monitoring and control—both on shore and off. Applications include control rooms as well as accessing radar and GPS systems on multiple bridge control stations. KVM extension solutions also link technical equipment rooms to bridges, and they can manage control processes.
Certain high-performance KVM products are pre-certified and allow maritime engineers to remain compliant with the IEC standard. These six are available from Black Box:
-Both support a variety of power supply options with a chassis that can hold up to six DKM modular cards.
ACX1MT-DHID-C and ACX1MT-DHID-2C DVI-D, USB HID, CATx Transmitter and Receiver
-Both can be installed in the DKM modular housing chassis.
ACXC48: 48-Port Compact DKM Switch
-This switch enables matrix switching and management for DKM extenders.
KVP4004: Multiviewer KVM Switch
-This switch provides access to up to four CPUs that can be monitored simultaneously in real time.
The IEC 60945 certification is issued only after rigorous testing. For example, among other qualifications, KVM technology must be proven to withstand the vibration, humidity and temperature extremes common in marine environments.
To achieve certification, Black Box helped customers perform their own critical equipment tests in the field to ensure these products meet the demands of their profession. The IEC 60945 accreditation means these tools can be deployed anywhere on a vessel, from the engine room to the technology room and the wheelhouse.
Black Box plans to release additional products that meet IEC 60945 standards in the future. Learn more about our maritime industry expertise and IEC 60945 accreditation, or visit our digital KVM Switches for product information.
Extend 4K resolutions at 60Hz over a single fibre cable in a point-to point extension or multipoint-to-multipoint matrix configuration for the highest onscreen resolutions in post-production suites. DKM FX 4K60 Interface Cards support 4K60 in full, 8-bit color depth.
More production suites are deploying 4K monitors for viewing, live production, and post production. For example, the Black Box DKM solution is being deployed at fileCAST Media GmbH. The manufacturer of the new LiveLogging solution for its Online Media Library (OML) platform is using Black Box technology to extend signals and connect to live production multi-feed environments. The purpose is to tag media content from multiple sources during a live event. This will enable content owners to offer valuable media assets in a searchable format in near real time.
4K in post-production editing suites will enhance an editor’s ability to see how the finished product will appear. 4K extension at 60 Hz has been challenging in the past because 4K requires higher bandwidth. The DKM FX 4K60 cards can overcome this challenge because the system also uses high-speed interface cards to support high-bandwidth signals. In addition, control surfaces for post-production editing that use high-speed USB, such as DiVinci Resolve, can be deployed using these interface cards.
The DKM FX system is flexible, scalable, and highly reliable. Video standards supported by interface cards in the modular housing include DVI-D up to 2560 x 1600; HDMI up to 2560 x 1440; and DisplayPort 1.2 (4:4:4) resolutions up to 4K.
The DKM FX Modular Housing frames come in 2-, 4-, or 6-slot chassis with optional redundant power. The 21-slot frame is 1U for rackmounting in a server room or machine room. Fibre cable supports distances up 1000 metres over multimode fibre or 10 kilometres over single-mode fibre, which means editing and post-production suites can be in different buildings in a large enterprise solution.

Machine vision technology—the image-based automatic inspection process—has matured greatly and is now becoming an indispensable tool in manufacturing to increase quality and profitability. USB 3.0, with its 5-Gbps throughput and ability to send power and data over the same line, has greatly contributed to this growth.
What is machine vision?
Machine vision is an image-based, automatic inspection and analysis system for applications, such as process control. It automatically takes pictures to inspect materials as they come down the assembly line.
Other machine vision applications include:
Medical vial inspection.
Robot guidance and orientation of components.
Engine parts inspection.
Machine vision uses a small industrial camera and lights mounted near an assembly line to take pictures of product as it passes. The images are then analysed by software to determine if various aspects of the product meet acceptable specifications. For instance, if a label is misplaced, the bottle will be rejected. All of this is done at incredibly high speeds—fractions of a second.
Years ago, machine vision systems were very expensive, costing hundreds of thousands of dollars. But in the last 15 years or so, advances in technology have brought the cost of machine vision down, making it a practical solution for 100 percent quality control. And the cost for implementing machine vision keeps decreasing as technological capabilities increase.
Machine vision is now an indispensable tool for quality assurance, sorting, and material handling in every industry, including electronics, food processing, pharmaceuticals, packaging, automotive, etc. It is an economical way to make sure sub-spec product is rejected. Machine vision can be used to inspect for geometry, placement, packaging, labeling, seal integrity, finish, color, pattern, bar code, and almost any other parameter you can think of.
USB 3.0 and machine vision
USB 3.0 brings a number of advantages to machine vision systems. Because of its 5-Gbps throughput, ten times more than USB 2.0, it eliminates problems of stability and low latency for image transmission and camera control. USB 3.0 enables the transmission of higher-resolution, higher-frame rate video with no loss of quality.
USB 3.0 also sends data and power on the same line. This is enough to power a camera without worrying about a separate power supply or power line.
In addition, compared to older systems, USB 3.0 is plug-and-play, making it easy to swap out cameras and other hardware, such as USB 3.0 extenders, and other devices.
KVM matrix switching gives multiple users access to a variety of target devices, including but not limited to CPUs, digital signage, and servers; the ability to monitor workflow; and flexible control of visual and peripheral elements.
Deploying KVM extension that operates over a LAN/WAN (local area network/wide area network) and incorporates virtual and physical CPUs gives retailers access options, reduces clutter in the workplace, and saves on energy costs.
In retail and inventory management systems virtualized remote computing is especially advantageous. Receiver units at the cash registers can access information on a virtual machine that runs on a server appliance.
This remote virtual system gives users access to their Active Directory accounts that is incorporated into a connection broker, with no need to set up a separate directory on the KVM system. The receivers gain access to virtual machines via Microsoft® Server 2008 or Microsoft Server 2012. By utilizing a connection broker, the virtualized machines can be easily duplicated, enabling workers to connect to the first available target without having to identify the target. This streamlines workflow and simplifies processes in busy retail applications.
In addition, a KVM system that works over a LAN/WAN this way supports NLA (network level authentication) for security. It also can continue to support physical CPUs while expanding into virtualization.
As is seen in KVM technology, other benefits include a low total cost of ownership (TCO); improved operability and quick ROI; maximum, scalability, and improved reliability; and green IT solutions with energy-saving design and distribution.

Industrial connectivity and KVM control room solutions for upstream, midstream, and downstream environments.
As the oil and gas industry continues to grow, more and more well sites, pumping stations, pipelines, processing plants, and refineries are being built. Along the entire route, safe, reliable networking and industrial automation are critical to smooth operations, efficiency, and productivity.
In 2014, the United States produced 9.2 million barrels of crude oil a day. The U.S. is now the largest producer of oil and gas, overtaking Saudi Arabia and Russia due to production from the Marcellus Shale. However, reservoirs of oil are becoming more difficult to access and increasingly less productive. To keep pace global consumptions, oil companies must constantly look for new sources of petroleum, as well as improve the production of existing wells.

Analog technology can’t keep up in the digital marketplace. Digital video is sharper and digital KVM is faster. Don’t get left behind in the digital revolution.
1. The VGA standard is being discontinued.
The VGA standard will not be supported going into 2015. Analog KVM and video won’t work any longer either. VGA sources and displays are getting increasingly difficult to find. We recently heard from a client who had to buy VGA parts on eBay.
2. Digital technology is distinctly better.
Digital technology improves users’ experiences by providing crystal-clear images at any supported distance. HD video is delivered pixel by pixel to digital displays at higher resolutions and increased color depth.
3. Digital systems are bigger and better.
New larger matrices and IP-based systems increase flexibility and enable connecting to a much higher number of endpoints. Thousands of devices can be incorporated into one unified system. On a digital matrix system, I/O ports are interchangeable, making changes and adds as simple as plugging a device into a port.
4. HD video switching is faster than it’s ever been.
Digital systems provide instantaneous HD video switching with no delay. Digital KVM switching is much faster, too, nearly instant rather than having to wait several seconds for video to show up.
5. Digital KVM improves the user experience.
Digital KVM systems feature improved USB support and compatibility with most other USB devices on the market: touchscreens, flash drives, tablet computers, as well as the workhorses, keyboards and mice.
6. Higher resolutions mean better images.
Increased bandwidth gives users the capability to work with images at higher detail levels as well as fit more content on the desktop for a more efficient workflow. Future-proof systems accommodate support for WQXGA (2560 x 1600) and 4K/UHD (3840 x 2160). Wherever users need pixel-perfect image transmission, they can now get it, via CATx or fiber cabling. Plus, send USB, serial, and digital audio signals.

Here’s a checklist to use as you shop for a future-proof, high-performance digital KVM switch or switching and extension systems. It’s easy to remember as FAR-PARSS.
Any enterprise-wide KVM system should be flexible enough to input and output many types of video and peripherals, especially if you are in broadcast or command and control. Video signals such as DVI, HDMI, and VGA should be supported with resolutions ranging from 1080p to 4K. Other signal types to look for are audio, USB 1.1 or 2.0 for peripherals like keyboards and mice, and serial signals for industrial applications.
A flexible system should also be scalable for future growth. Calculate the total number of video sources and displays you have, and try to plan for growth. The KVM switches need to support current and future users with enough ports so that users do not have to create silos of servers and users. Look for a KVM system that can replace a video-only router with a high-performance digital KVM matrix switching system. A management controller enables central administration of the system. Does the management controller use a graphical user interface, or a text-based OSD?
When a KVM system can support video resolutions of 1920 x 1080 at 60 Hz or 3840 x 2160 at 60 Hz, test to make sure video does not lag or drop frames with rapidly changing content. Not all analog KVM systems or IP-based systems are up to the task, although most digital systems, including digital IP-based systems, can support fast, high-definition video.
Test keyboard and mouse setup to make sure there is no latency. A true USB emulation KVM switch is responsive and consistent; an unresponsive K/M jars the operator out of his/her workflow.
Optimally, a high-performance digital KVM system improves users’ productivity. In a matrix setting, all resources and displays can be connected and switched between by multiple users. Collaboration is enhanced by the ability to view and control the same resources simultaneously.
Calculate the longest distance between your endpoints, and make sure the KVM system can work over CATx or fiber cabling – or a mix of both – to reach all your targets. With digital matrix KVM systems, multiple users should have real-time access to targets.
New generation KVM systems will support redundancy options such as multiple power supply units for 24/7 uptime. Be sure to eliminate single points of failure. Make sure the system you select can support routing transmitters and receivers through two separate core KVM switches for full redundancy.
Many digital KVM switching systems support video-switching speeds of under a half second. Anything longer interrupts an operator’s workflow as he or she switches between resources and may be noticeable to a viewer. Does your KVM solution support custom keyboard shortcuts (also called hotkey shortcuts) that can be set for switching a local display as well as remote displays, such as other user terminals for collaboration or a video wall?
Lastly, KVM switching and extension systems need to be secure. Be sure administrators can assign specific access rights to specific resources. Remote configuration and maintenance of the KVM system enables an admin to securely log onto a system.
When you can mark off all eight of these categories, you’ll have maximized your ROI.
Universal Serial Bus (USB) is a technology that enables users to interact with a specific device for a specific function. USB supports a multitude of devices, ranging from simple devices such as keyboards, and mice, to more complicated devices such as game controllers, digital cameras, printers, network adapters, external storage — the list goes on. Use varies from basic functions, such as typing, all the way to transferring large files to/from external storage devices.
Several different USB modes are available today:
USB Low Speed (1.5 Mbit/s)
USB Full Speed (12 Mbit/s), also known as USB HID
USB High Speed (480 Mbit/s), also known as USB 2.0
USB SuperSpeed (5 Gbit/s), also known as USB 3.0
USB SuperSpeed+ (10 Gbit/s)
USB is used most commonly for keyboard and mouse input, or alternatively, keyboard and touchscreen input instead of mouse. These devices are classified as Human Interface Devices (HID). USB HID is designed to enable a user to interact with a system by using a USB keyboard and pointing device that use very little bandwidth, typically way less than 12 Mbit/s. On KVM (Keyboard, Video, Mouse) switches you will find that most will have two USB HID ports for a keyboard and mouse, and additional ports for USB High Speed devices to connect other, faster devices like printers or storage.
The USB HID ports found on most KVM switches analyze the incoming data flow from the attached USB keyboard / mouse to look for a sequence of key strokes that prompt the KVM switch to take a particular action (such as bringing up an OSD, switching CPU ports, enabling scanning, etc.). Since this USB HID traffic is being monitored at lower rates, it is nearly impossible to plug a USB High Speed device into the HID port and expect that the high-speed device will function properly. The USB HID ports on a KVM switch only expects to see a USB keyboard and USB mouse — nothing more. Each USB device, including the keyboard / mouse, has properties associated to it that include but are not limited to:
It is very important in a KVM application that these USB device properties are correctly transferred to the host computer. The proper drivers / software need to be loaded upon USB enumeration. USB enumeration is done between the time of plugging the USB device into the target computer / server, and the time that it is recognized; enumeration time can vary between 1 and 16 seconds depending on the OS and USB device. If the device properties are not properly transferred to the computer / server, then the chances of the device working is slim to none.
On Black Box KVM products, we “trick” the computer / server into thinking a generic USB keyboard and a generic USB mouse are always connected whether or not they are plugged into the KVM console. This feature is called USB emulation. USB emulation will ghost the generic keyboard and mouse on the KVM switch so the user can quickly switch computer ports without having to re-enumerate the USB devices every time they establish a new connection. We also have proprietary firmware in our KVM hardware that can properly negotiate the communication between the console keyboard and mouse and the attached computer or server. USB emulation is geared more towards wired devices instead of wireless devices; however, in some cases wireless keyboards and mice will work when connected to the KVM switch.
You may find some wireless keyboards and mice do not work with KVM switches due to a composite wireless transmitter trying to send both keyboard / mouse packets into a single USB HID port on the KVM switch. It depends on the wireless device manufacturer, how they prepare their USB packets before transmission, and the way they follow the USB specification. One thing to keep in mind is that not all USB HID devices will work on a KVM device as it would on a regular computer because of the way the device negotiates with the switch and the usage of the USB device properties (vendor ID, product ID, device class, etc.). The KVM switch does not have all of the supporting drivers like a regular operating system, so with it being pre-coded into the firmware, you will sometimes see compatibility issues with a very small percentage of USB HID devices in the market.
The next most common usage of USB is related to transferring files to and from a computer / server system from a thumb drive or external storage device. This type of application typically uses USB High Speed at 480 Mbit/s, and on newer systems USB SuperSpeed so that the file(s) can be transferred faster. Black Box offers KVM switches that can support these types of devices; however these USB High Speed ports do not monitor the USB data flow for keyboard hotkeys. If you attempt to control the KVM switch functions using keyboard hotkeys while the device is plugged into the USB High Speed port, it will never work. You have to use the USB HID ports for this.
What is a KVM extender?
KVM stands for “keyboard, video, and mouse,” and a KVM extender is basically a device that extends these interfaces and enables remote access to a computer over distances from a few feet up to several miles, or even over the Internet. A KVM extender unit consists of a transmitter device, sometimes called “local unit,” and a receiver device, also called “remote unit.” These devices can be connected over either CATx copper or fiber cable, and the newest technology can even extend signals over a standard IP network. You can connect your PC to a transmitter at work and plug in the receiver at your home office and work at your computer, just like you would with a direct connection.
What are the interfaces being used?
The video interface is usually either DVI or HDMI on most modern devices, while older computers might be equipped with VGA only. In the past, keyboard and mouse were always separate interfaces and were using a PS2 6-pin mini-DIN connector. That technology has been almost completely phased out, and now USB is the standard connector. It usually doesn’t matter where you plug in your mouse or keyboard, as long as it is a USB port. Other optional interfaces that can be supported are audio and RS-232.
Why would anyone need a KVM extender?
Computer fans are loud, and computer CPUs have fans for cooling because they generate a lot of heat. Plus, they take up a lot of space. None of these features is ideal in an office environment. By using a KVM extender, CPUs can be backracked in a server room in a temperature-controlled environment. All the user needs is a tiny receiver unit on the desk where the keyboard, video display, and mouse would be connected. An industrial environment has different challenges. The work environment might be dusty or dirty—areas where regular CPUs with fans will not last long. The fans will pull the dirt into the cabinet, clogging it up and causing the computer to overheat. By using a KVM extender, the PC can be relocated to a cleaner environment, and the keyboard, video, and mouse workstation can be connected to a remote KVM unit that is fanless. These are just two examples of how KVM extenders are being used, but the variety of applications for KVM extenders is extensive. Learn more at Black-box.eu/KVM-Extenders or check out our KVM Extender buyers guide.
When you or a loved one places an emergency call, it’s routed to your local dispatch center. From here the dispatcher assesses and categorizes your emergency. If necessary, they assign field personnel — EMS or police, for example — to incidents. Dispatchers log all calls and activities, monitor automatic vehicle location (AVL), and geographic information (GIS) with the Computer Aided Dispatch system. This system gets the police officer, fire fighter, or ambulance to your location to prevent situations from escalating and to save lives.
As you can imagine, time is of the essence. In today’s modern computer-aided dispatch center, people and machines work in tandem. Dispatchers often have a minimum of three computer monitors in front of them. Each of these has dedicated tasks and information being displayed. In order for a dispatch operator to operate all three machines he or she may end up with three separate keyboards and mice cluttering their desktops. The multiple keyboard/mouse (K/M) workstations lead to three main pain points.
Confusion as to which keyboard and mouse to use for which system.
Ergonomics of having to swivel or reach in order to access the correct keyboard and mouse.
An interruption in the workflow of having to physically switch to a different keyboard and mouse.
All of these points lead to increased response times, which are precious seconds that could be the difference between life and death. Response times are the leading statistic by which dispatch centers are judged for efficiency and effectiveness.
Popular options that have worked in the past have significant shortcomings.
The first is a software-based solution that allows a dispatch operator to use one keyboard and mouse on multiple machines. In theory, this works well, but here are three main shortcomings to a software-based solution.
Security risk of having to install additional software. Dedicated machines are often configured by a manufacturer that will not support your system if you install any unauthorized software.
Software-based keyboard and mouse switching relies on the network. Spikes in Internet activities can render the keyboard and mouse unresponsive or extremely slow to respond; the operator has to wait until the network activity clears up. Response times are increased, which is unacceptable.
One machine acts as a server while the other machines act as clients. In this setup, if the “server” machine goes down, you lose keyboard and mouse on all other machines.
The second solution is a desktop, hardware-based keyboard, video, and mouse (KVM) switch. This is a better solution because it requires no dependency on the network and is not adversely affected by the health of one machine on the system. However, the pitfall is a stuttered workflow; multiple port, hardware-based KVMs usually require the emergency dispatch operator to physically push a button on the KVM switch or press multiple keys on the keyboard to switch keyboard and mouse focus.
Black Box has introduced a new solution that combines the best of both worlds: the Freedom II. The Freedom is a hardware-based keyboard, video, and mouse switch. However, built into the hardware box is an innovative solution that provides the ability for a dispatch operator to switch between up to four machines simply by moving the mouse across the monitors. When the dispatch operator’s mouse cursor is on screen 1, keyboard and mouse focus is on machine 1. If the dispatch operator wants to access and control other machines he or she simply has to move the mouse across the screen to the second, third, or fourth monitors. This is an intuitive solution with no learning curve, increased operator comfort in ergonomics, and no interruption in workflow. Its deployment ultimately leads to decreased response times. This is an easy-to-implement hardware solution with no software to install and no dependency on networks. Learn more in the video below, or check out our 9-1-1 Call Center Case Study.

Until recently, the National Information Assurance Partnership (NAIP) used Common Criteria Evaluation & Validation Scheme (CCEVS) to evaluate and approve KVM switches for security. EAL2 and EAL4+ are tests regarding the process of the design, testing, verification, and shipping of security products. This protection profile is an international standardized process for information technology security evaluation, validation, and certification.
NAIP has determined that EAL and CCEVS are no longer adequate security standards for KVM switches that connect to systems with differing security classifications. As a result, they upgraded the Protection Profile (PP) for peripheral sharing switches to PPS 3.0. Still, the next generation of secure switches are going to need to be TEMPEST-approved for the tightest security measures available.
TEMPEST testing, while classified, is regarded as a process that assesses the port-to-port isolation required for certain KVM switches. A TEMPEST approval means the necessary isolation is achieved and qualified. Additionally, the threat of data leaking by various covert electromagnetic eavesdropping mechanisms has been evaluated and found to be secure.
The TEMPEST designation is often required by military organizations. TEMPEST, as a security standard, pertains to technical security countermeasures, standards, and instrumentation that prevent or minimize the exploitation of vulnerable data communications equipment by technical surveillance or eavesdropping.
A desktop KVM switch at its most basic, is simply a hardware device that enables one workstation consisting of a keyboard, video monitor, and mouse to control more than one CPU. Desktop KVM switches are usually 2- or 4-port switches, and by pushing button or using keystrokes, users can easily access information and applications on completely separate systems.
Secure KVM switches fill a special need in switching for users, such as those in the military, government agencies, or law enforcement, who need to access information stored at different classification levels on physically separate systems. A secure desktop KVM switch is usual a two or four-port switch that provides control and separation of PCs connected to networks of differing security classifications. TEMPEST-approved switches offer the following features:
High port-to-port electrical isolation, which facilitates data separation (RED/BLACK). Channel-to-channel –80-dB to 60-dB crosstalk isolation protects against signal snooping, so software tools and applications cannot be used to access any connected computer from another connected computer.
Switches are permanently hard wired, preventing access from one CPU to the others or access from one network to others.
External tamper-evident seals make it easy to spot attempted tampering.
Users can safely switch among as many as four computers operating at different classification levels.
Unidirectional flow of keyboard and mouse data means the computer cannot leak data along K/M signaling channels.
USB host controller erases entire RAM at each channel switchover. This prevents residual data from remaining in the channel after a channel change and being transferred to another computer.
Only keyboard and mouse devices can be enumerated at the keyboard and mouse ports. Any other USB peripheral connected will be inhibited from operating, preventing the upload or download of unauthorized data.
The Secure Desktop KVM Switches with USB from Black Box surpass the security profiles of most other KVM switches because they have received approvals and certifications in the TEMPEST testing standard.
