What is the Kensington Lock?

Many of our Mini-PCs especially those in the Digital Signage field, are often used in public places such as fairs or advertising panels. Where there are many people, there is also a risk of thieves. To protect against this risk, the Kensington Lock has proven itself. Read on to learn what stands behind this port and how it works.

Kensington Lock as an anti-theft system

In 1992 the company Kensington released the first ever laptop lock called Kensington Lock. This stands for a lock that serves as theft protection for Notebooks, as well as Mini-PCs. Nowadays the term Kensington Lock represents every lock that works the same way as the original.

Most of the times the lock is equipped with a wire cable and a loop at the end. When opened, this construction can be attached to objects such as furniture.

As a deterrent of walk-in thieves, the Kensington Lock is a good option. Nonetheless, professional thieves with appropriate equipment sure won’t keep off because of this lock. Even the use of the lock per se can be a weakness when it is attached incorrectly, for instance on light-weight furniture.

The Kensington Security Slot

To benefit from this lock, the device has to have the standardized connector. It is called Kensington Security Slot and is provided by most of the biggest manufacturers. The slot is approx. 3 x 7 mm big and in plastic housings often secured with metal to prevent the lock from breaking out. Sometimes the slot is even connected to system-relevant components, so that the device is useless in case of theft.

Just like its predecessor, the Mini-PC is 4K capable and convinces with its excellent price/performance ratio. But new is though: the CPU is now freely selectable. From the Intel Pentium to the i7 processor, we got the right solution for every application. [description] =>

From Pentium to i7: Coffee Lake in all variants

For the performance of the CORE 2 spo-comm counts on 8th generation Intel CPUs (Coffee Lake), which are extremely economical with a TDP of just 65 watts. Customers can choose between an Intel Pentium G5400 at 2 x 3.7 GHz processor, a Core i3-8100 at 4 x 3.6 GHz, a Core i5-8400 at 6 x 2.8 GHz (maximum 4.0 GHz) and the ultra-performant Core i7-8700 at 6 x 3.2 GHz (up to 4.6 GHz). This allows the Mini-PC to perfectly match to the performance needs of the particular application. Compared to its predecessor, a huge increase in performance can be seen. Benchmarks show, that even the Pentium processor performs better than the Intel Core i5 in the previous CORE.

Lots of storage in a small space

The ultra-compact industrial PC with dimensions of just 142 x 167 x 37 millimeters offers an enormous storage space. The CPU can be supported with a maximum of 32 GB of SO-DDR4 RAM. In addition, the CORE 2 offers space for up to two SSDs: One m.2 starting with 240 GB (maximum 960 GB) as well as a 2.5-inch SSD, which starts already with 120 GB of storage space. Like this, it is possible to save for example the operating system and data on different media.

Connections for multimedia solutions

The new CORE 2 has got all the connections a digital signage player needs. A DisplayPort and HDMI port allow the playback of content in 4K resolution (3840 x 2140 pixels) – thanks to one line-in and one line-out also with audio. Furthermore, there are three USB 3.1, one USB Type C and two USB 2.0 ports on the Mini-PC. Network connections are made possible by the LAN interface on the back panel or optional Wi-Fi. If you use the CORE 2 in public places, you can protect it against theft with the Kensington Lock. As operating systems, Windows 10 in the Home, Pro or IoT variant and Linux Ubuntu are available.

The AMD® Ryzen V1807 CPU and the integrated AMD® VEGA 11 GPU provide a graphics power that enables digital signage applications in the high end field. [description] =>

AMD Ryzen V1807 CPU for high end digital signage

As the name suggests, the KUMO Ryzen has an AMD Ryzen V1807B CPU with 4 x 3.35 GHz (up to 3.8 GHz) as its centerpiece. Because the special construction of this processor combines the CPU with the GPU power, a very high computing power is ensured. Thanks to this particular feature also the processing of multimedia content is not inferior to a dedicated graphics card. These features are combined with an up to 32 GB big DDR4-RAM and two up to 500 GB or 960 GB big HDDs respectively SSDs. Like this, challenging digital signage applications are possible.

4x 4K due to Display Port 1.4 and AMD® VEGA 11

With dimensions of only 180 x 210 x 55 mm (W x D x H) the housing of our KUMO offers a lot of different interfaces. The most important for the digital signage field are probably the four DisplayPort 1.4, which can be found on the back panel of the KUMO. In combination with the integrated graphics unit AMD® VEGA 11 content in a resolution of 3840 x 2160 @ 60Hz can be played on up to four displays at the same time.

Theft-protection, optional WiFi and 6x USB

The interfaces of the KUMO Ryzen appear in the usual KUMO design. Next to the centered power button the front panel offers two of the four USB 2.0 ports. The other interfaces are located on the back panel. These include on one hand four other USB ports – two times 2.0, two times 3.1 – and on the other hand two audio and two LAN-ports can be found. In addition to this two COM ports are located on the back. The lateral placed Kensington Lock also guarantees theft protection. Thanks to the two integrated M.2 ports WiFi is optional.

From Windows 10, to IoT Enterprise to Linux Ubuntu

The options for the software of our KUMO Ryzen are also worth a look: The system can be equipped with the operating systems Windows 10 Home, Professional and Linux Ubuntu. Using Windows 10 IoT Enterprise even different adjustments – depending on the customer request – can be realized.

Part 3: Cables [authorId] => [active] => 1 [shortDescription] => In the first two articles of this series that deals with the health of Mini-PCs, we already took a look at the right cooling system and the SmartFan function of actively cooled devices. But also from the exterior, or rather on the housing of Mini-PCs there are things that can have an impact on the health of a Mini-PC: Cables that are connected to the different ports. [description] =>

Whether it is to get a connection to the internet or to external devices: Wires always play a role. If these are not chosen and installed correctly, they can easily break or rip out and in conclusion, damage the Mini-PC. Which options are there to protect the Mini-PC from this?

Cable relief

For flexible electric leads, which involves cables, there is a mechanical safeguard, the so called cable or strain relief. For non-stationary electric supplies (for example wires, circuit boards and audio connectors) this cable relief is obligatory and standardized after EN 62444.

Cable reliefs are mostly made of metal or plastic clips that prevent ripping out cables by clamping them. What this looks like you can see here.

Cable gland

Another possibility is the usage of screwable cables which, among others, serve the cable relief. The benefits are many. A screwable power adapter for example (see pic. 3) cannot be ripped out so easily or by accident. Like this, the PC is constantly supplied with power and the operating system is spared from damage through a sudden reset. Another benefit of screwing cables, for example on to the housing of a Mini-PC is a better isolation. Due to the tight and dense connection, outside influences such as dust or moisture in production halls, can no longer get inside the system and extend the lifetime of the Mini-PC.

Today, according to DIN EN 60423, metric screw threads are mandatory, as well as a protection class of at least IP54. To protect humans of potential danger when using the devices, protection classes of IP 65 (protects from dust and water jets) or IP68 (dust and waterproof) are common.

Which cables and interfaces are screwable?

After all this theoretical knowledge, let’s move on to the practice: Which cables are even screwable? The most common are probably the serial interface RS-232, also known as the COM port, and the multimedia interfaces VGA and DVI (see pic. 2). Their sockets and plugs are equipped with threads as standard and like that, prevent the cable to rip out.

Other protection options

There are also cables that sit firmly in the socket, without being screwed. This applies on one hand for the LAN cable and on the other hand for the multimedia interface DisplayPort. Both of them back on engaging hooks, so called locking tabs that ensure the cable to sit tightly. To loosen the cable the nib on top of the plug can easily be pushed down.

With the HDMI cable it is a completely different story. Since there is no protection included fundamentally, by this time there are several different options that want to ensure the cable to be stable. On one hand there are specific silicone cases for the cable and on the other hand you can get HDMI cables that have a mechanism with which a locking system can be turned on and off manually.
