The abbreviation HDMI stands for “High Definition Multimedia Interface”. As with DisplayPort, it is a digital interface for the transmission of high-resolution video and audio signals. 

Good to know: What is DisplayPort?

Applications of HDMI

HDMI is mainly used in consumer electronics to connect DVD players, laptops or computers to televisions or monitors.

HDMI-Out and HDMI-In

Even if they look the same, a distinction is made between HDMI input and output. The HDMI output is the port on the device that transmits the content. (e.g. computer, console, etc.) 

The HDMI-In port, however, turns the tables: as the name suggests, it is an input, i.e. it is in the device that receives the content. (e.g. screens) 

However, there are always HDMI-in ports on computers, such as on our ONE i5. An HDMI-in port on a computer essentially works like an HDMI input on a TV or monitor, with the difference that it can receive content from external devices such as games consoles, Blu-ray players or video cameras.

What versions does HDMI have?

In order to keep pace with constantly advancing technology, the HDMI interface has been continuously developed. The various specifications, which amount to a total of 13, have confused many buyers over the years. We also want to keep it short and therefore only go into the most important updates to the interface:

• The first HDMI standard 1.0 was published in 2002 and provided a maximum data rate of 4.95 gigabit/s and a maximum image resolution of 1920 x 1080 pixels.  
• It was not until version 1.3 in 2006 that the image resolution was increased to 1560 x 1440 pixels. Furthermore, a new connector type, namely HDMI type C, was introduced to the market with this version.  
• The next update came in 2009 with version 1.4, which offers a maximum picture resolution of 3840 x 2160 pixels, i.e. 4K.
• The latest version of HDMI is HDMI 2.1b, which came onto the market in 2023 and includes general corrections, clarifications to improve interoperability and the incorporation of errata – a maximum picture resolution of 8K is now possible.

What do the designations for HDMI cables mean?

In order to create a clearer and more comprehensible labeling of the cables, they are no longer marked with the version number (1.0, 1.4, etc.), but are divided into four speed classes:

• HDMI standard: The transmission rate of up to 2.25 Gbit/s enables a resolution of 720p or 1080i at 60 Hz. Supports HDMI versions up to 1.3.
• HDMI High Speed: Resolution of 2160p at 30 Hz. Supports all versions up to 1.4.
• HDMI Premium High Speed: Resolution of 4096p at 60 Hz. Supports versions up to 2.0.
• HDMI Ultra High Speed: Resolution of up to 8K@60Hz. Supports all versions up to 2.1.

Advantages of HDMI

With the help of HDMI, picture and sound can be transmitted via a single cable, making it much easier to connect AV devices. It also means that there is no need for an additional audio connection, which is particularly beneficial for our smallest mini PCs. HDMI also offers excellent quality, can transmit 4K and 3D content and supports surround sound.

Team Day 2024 – Goals, pizza and pasta

Like last year, the event took place on 22.03. the spo-comm team day took place at our headquarters. Our CEO Michael Sporrer kicked off the event with a short presentation in which, among other things, upcoming changes were announced and our targets for the year were underlined once again. 
Afterwards, we started our afternoon together with delicious dishes from L’Osteria and had lively discussions as well as good and amusing conversations.

Finally – the CORE 3 is here

As already teased in the last “What’s New?” article, nobody has to live without CORE – now the time has come, the CORE 3 is available!
The CORE 3 is characterized in particular by its slim housing, which measures just 36mm x 147mm x 165mm and offers a wide range of connection options. With 3 DisplayPorts, two audio outputs, six USB interfaces, as well as two LAN and one COM RS232/422/485, it is a true genius when it comes to connectivity.

What is an IP address?

An IP address is an individual identifier that makes it possible to identify a specific device within a network , whether locally or on the Internet. Similar to telephone numbers or car license plates, it is used to localize the location of a device and make it accessible for communication purposes.

The Internet Protocol (IP) defines the rules according to which data is sent via the Internet or local networks. It determines the format of this data and thus ensures a smooth exchange between different devices.

Types of IP addresses

IP addresses can be divided into different categories. On the one hand, there are public and private IP addresses. Public IP addresses are uniquely identifiable on the Internet and enable communication between devices via the World Wide Web. Private IP addresses, on the other hand, are used for internal communication within private networks and cannot be accessed directly from the Internet.

Furthermore, there are distinctions between IPv4 and IPv6 – v4 or 6 simply stands for version4 or version6. IPv4 uses a 32-bit address and thus enables around 4.3 billion unique addresses. However, due to the exponential increase in networked devices, IPv4 is reaching its limits, which is why the newer IPv6 with its 128-bit addresses was developed to meet this demand.

IP addresses can also be static or dynamic. Static IP addresses remain unchanged and are permanently linked to a specific device, while dynamic IP addresses can be reassigned as required.

The connection to the MAC address

In addition to the IP address, each network device also has a so-called MAC address (Media Access Control). It is firmly anchored in the hardware of the device and is used to uniquely identify it in the local network.

The connection between IP address and MAC address is that the MAC address operates on the physical level, while the IP address operates on the logical level of the network. When a device sends data, the IP address is used to identify and localize the target device. The corresponding MAC address is then used to transmit the data on the physical level of the network.

IP addresses are therefore the backbone of modern digital communication. They make it possible to connect devices with each other, exchange data and use the Internet. The connection to the MAC address ensures smooth transmission of information in the network.

What is a MAC address?

MAC stands for Media Access Control. A MAC address is a unique identifier that is assigned to each network device. This address, which consists of a 48-bit number combination, uniquely identifies each network interface in a network. The MAC address is usually displayed in hexadecimal form, which means that it consists of numbers and letters. Interestingly, the MAC address is divided into two parts: The first 24 bits identify the manufacturer of the device, while the remaining 24 bits identify the individual device.

(https://de.wikipedia.org/wiki/MAC-Adresse) 

What are MAC addresses used for?

MAC addresses play a decisive role in networks. In order to receive a signal from another device, the receiving device must have a unique MAC address. Without this, the data sent would come to nothing. The MAC address is therefore to be understood analogously to a house number, which enables the resident to receive mail. In addition, network administrators can use MAC addresses to control access to the network. By authorizing or blocking certain MAC addresses, you can ensure that only authorized devices can access the network. This improves network security by preventing unauthorized access.

How do I find the MAC address of my device?

It is relatively easy to read out the MAC address of your device; this is usually written on the inside of the network sockets. The method of reading the MAC address from the software varies depending on the operating system:

• Under Windows, you can find the MAC address in the “Status” of a network connection on the “Network support” tab in the “Details” or use the “ipconfig/all” command in the command line.
• Under Linux, execute the command “ifconfig” in the terminal to see the “HWaddr” (hardware address).
• On a device with Mac OS, you can either use the “ipconfig” command in the terminal or find the MAC address in the “Network” area of the system settings.

In summary, it can be said that MAC addresses play an essential role in communication between devices in e networks, whereas on the Internet, devices are mainly identified via IP addresses   .

IP protection classes at a glance

The letters “IP” in the IP protection class stand for “Ingress Protection” or “International Protection”. They indicate the degree of protection of electrical devices against the ingress of solid foreign bodies (first digit) and moisture (second digit). “Ingress Protection” shows how well a device protects against external influences, and “International Protection” indicates that these standards are recognized and standardized worldwide. Together, the letters represent the global standards for describing the degree of protection of electronic devices.  

The first digit of the IP classification refers to protection against solid foreign bodies. For example, a ‘0’ means no protection, while a ‘5’ indicates dust protection and a ‘6’ dust-tightness. From large particles to fine dust, these digits provide a clear overview of how well the appliance is protected against the ingress of solids.

The second digit indicates how well the device is protected against moisture. Here the scale ranges from ‘0’ for no protection to ‘8’ for protection against permanent immersion under special conditions. Whether it is dripping water, splashing water or even temporary submersion – these figures provide clear orientation.

A protection class for every application

IP protection classes have a direct impact on the possible uses of electronic devices. An IP44 classification, for example, means protection against solid foreign objects with a diameter of one millimeter or more and protection against splashing water. This protection class could be ideal for use in environments where moisture and small particles play a role, for example in workshops.

For more robust requirements, however, you could look for devices with higher IP classifications. An IP65-certified device, for example, is not only protected against dust, but also against water jets from any angle. This makes it suitable for outdoor use where it may be exposed to severe weather conditions.

Selecting the right IP protection class

Choosing the right IP protection class is crucial for the longevity and performance of electronic devices. It ensures that a device can withstand the specific requirements of its environment, whether in a dusty workshop, a damp outdoor area or an underground system. It is therefore equally important for developers, manufacturers and end users to understand the IP classification and take it into account when selecting electronic devices.

Keywords such as IP protection class are not uncommon in our product portfolio either; the SQUARE 18, SQUARE 21 and our RUGGED Tab 10, for example, are IP 65 dust and water-protected. What’s more, our RUGGED Tab 10 is even MIL-STD-810G certified. This certification is a US military standard that defines the suitability of equipment for use in military applications.
