USB type-c, short for type-c, is a universal serial bus (USB) hardware interface specification. The new interface features a thinner design, faster transmission speeds (up to 10Gbps) and more power (up to 100 watts). The biggest feature of type-c double-sided pluggable interface is that it supports double-sided insertion of USB interface, which officially solves the worldwide problem of “USB never allowed to be inserted”. The USB cable that comes with it must also be thinner and lighter.

USB type-c has the following technical features:

1. The maximum data transmission speed is up to 10Gbit/ s, which is also the standard of USB 3.1;

2. The size of the socket end of type-c interface is about 8.3mm 2.5mm thin design;

3. Support the “forward and backward interpolation” function that can be inserted from both sides, and can withstand 10,000 times of repeated interpolation;

4. Standard specification cables equipped with type-c connectors can carry 3A current and also support “USB PD” beyond the current usb-powered capacity, which can provide up to 100W of power.

Appearance characteristics

1. The ultra-thin

Thinner bodies require thinner ports, which is one reason usb-c has emerged. Usb-c ports are 0.83 cm long and 0.26 cm wide. The old USB port, 1.4 centimeters long and 0.65 centimeters wide, is outdated. This also means that the end of the usb-c cable will be one-third the size of the standard usb-a cable plug.

2. No positive and negative

Like apple’s Lightning port, the usb-c port has the same front and back. This means that no matter how you insert the port, it is correct. Users don’t have to worry about the pros and cons of a traditional USB port.

The main function

1. Quick

In theory, usb-c ports have a maximum transfer rate of 10Gb per second. But apple says the new MacBook’s usb-c port has a maximum transfer rate of 5Gbps. The maximum output voltage is 20 volts, which can accelerate the charging speed. Usb-a, by far, has A transmission limit of 5Gbps and an output voltage of 5v.

2. Generalist.

The new MacBook’s usb-c port can transfer data and charge, or it can be used as a video output port to connect to external display devices. The only question is how apple will satisfy users who want to do all three at once.

3. Bidirectional

Unlike older USB ports, which transmit power in one direction, usb-c ports transmit power in both directions, meaning it can send power in two ways. So, users can not only charge their mobile devices with their laptops, but also charge them with other devices or mobile power supplies.

4. Backward compatibility

Usb-c is compatible with older USB standards, but users need to purchase additional adapters to complete compatibility. Apple says not only will apple officially sell the adapters, but third-party companies can also license them.

The difference between Thunderbolt 3 and USB 3.1 Gen2 Type-C

To figure out the difference between these two cables, you first need to clarify the concepts of Thunderbolt 3, USB 3.1, and Type-C. In fact, Thunderbolt 3 and USB 3.1 are both data transmission protocols. The difference between different transmission standards is mainly in the transmission rate. In terms of USB 3.1, it is also divided into USB 3.1 Gen1 and USB 3.1 Gen2. The maximum transfer rate of USB 3.1 Gen1 is 5Gb/s, and the maximum transfer rate of USB3.1 Gen2 is 10Gb/s. Type-C is an interface specification, in addition to other interface specifications such as Type-A and Type-B.

One of the reasons why users can easily confuse Thunderbolt 3 with USB Type-C is that both cables use the Type-C interface specification and look almost identical. Now in order to better distinguish between the two, Apple’s latest Thunderbolt 3 data line will have a lightning sign.

Although Thunderbolt 3 and USB Type-C have the same interface, they are paired with different transport protocols, namely Thunderbolt 3 and USB 3.1.

Despite differences in transport protocols, Thunderbolt 3 and USB Type-C can share the Type-C interface. For example, if the user connects to the Thunderbolt 3 interface of the display from the USB Type-C interface of the laptop, it can also be expanded. The only difference is that the bandwidth of the USB 3.1 Gen2 will be reduced from 40Gb/s to 10Gb/s.

Integrated graphics

The integrated graphics card generally does not have video memory, but uses part of the main memory of the system as the video memory. The specific number is generally automatically adjusted dynamically according to the needs of the system. Obviously, if you use integrated graphics to run a large amount of memory space, the impact on the entire system will be more obvious, in addition, the system memory frequency is usually much lower than the graphics memory of the discrete graphics card, so the performance of integrated graphics is inferior to the discrete graphics. With a motherboard that integrates a graphics chipset, it is not necessary to use an integrated graphics card. The motherboard can completely shield the integrated graphics card, but it is rarely done for cost.

Advantages

1. Low price
2. Good compatibility
3. Meet the demand
4. Low upgrade cost
5. Integrated graphics card means that the chipset integrates the display chip, we don’t need to connect the external graphics card.

Independent graphics

Independent graphics card, referred to as the independent display, Hong Kong, Macao and Taiwan regions called independent display cards, refers to the independent card, you need to insert the graphics card on the corresponding interface of the motherboard. The discrete graphics card is divided into a built-in discrete graphics card and an external graphics card.
A discrete graphics card is a graphics card that can be freely plugged and unplugged on a motherboard with a graphics card interface in the form of a separate board. The discrete graphics card has separate graphics memory, does not occupy system memory, and is technically ahead of integrated graphics, providing better display and performance. As an important part of the computer, graphics cards are very important for people who like to play games and professional graphic design.

Advantages

1. The discrete graphics card has separate video memory and does not occupy system memory.
2. Technically leading, providing better display and running performance.
3. And it can display multiple graphics cards inside the computer, and has powerful image processing capabilities.

The difference between discrete graphics and integrated graphics

From the performance power consumption, the integrated graphics feature is generally good, but basically meets some daily applications, the heat and power consumption is lower than the discrete graphics. Although the performance of the discrete graphics card is strong, the heat generation and power consumption are relatively high. In terms of 3D performance, discrete graphics are better than integrated graphics.
The discrete graphics card is easy to determine. A separate card is inserted in the motherboard slot. The interface on the card is connected to the signal cable of the display. Because the integrated chip is integrated in the North Bridge, there is no card, and the interface connecting the display is not on the card. It is usually placed together with the I/O interface of the motherboard backplane.

It support add Discrete Graphic Card

Mini host, also called mini computer, mini computer host, thin client (HTPC), minicomputer, cloud terminal or miniPC, others like to call it a desktop computer, it is a small size, low power consumption, ultra-quiet The high performance, stylish and beautiful computer host, the mini host has the basic properties and performance of the traditional desktop host.

Advantages of the Eglobal Mini PC

(1) Small and portable: Compact is the biggest feature of the mini-host. Its volume is generally 1/30 of the volume of a traditional desktop mainframe. It is equivalent to a 130-page book thickness, and the length and width are as large as A5 paper. For example, Datang’s mini-host is called a book computer, precisely because the host looks like a book standing quietly on the table. Of course, there are also smaller hosts on the market, such as computer sticks, which are equivalent to a U disk size. The mini-host is very convenient to carry, and can even be taken directly in the trouser pocket to bring more work and life. Convenience.

(2) Space saving resources: The compact size of the mini-host can be fixed by the pylon, can be placed at any small corner on the table, or can be fixed on the display or electricity with a dedicated pylon: behind the screen, making room for the current office or home life. The space resources are also a clean and tidy space on the desktop.

(3) Stylish and beautiful: Most of the traditional large desktop mainframes can not meet the aesthetic needs of modern people, and the stylish design of the mini-host, combined with the small and exquisite, whether it is on the desk, the living room or the study, is very artistic, giving Life and work bring a more enjoyable experience.

(4) Low power consumption, energy saving: The mini-host uses a low-power processor, and the thermal design power consumption TDP is generally around 10W-17W, while the traditional large desktop host consumes an average of 100W~150W, which is 10 times or more of the power consumption of the mini-host. (5) Silent and environmental protection.

(5) Silent and environmental protection: The loud noise of traditional big desktops has seriously affected the experience of computer workers, gamers and home life. In this ubiquitous living space, people can no longer afford more pollution. Due to the fanless heat dissipation design of the mini-host, the whole machine can achieve zero noise during operation, which brings a quiet experience of work and life, and has been well received by people.

(6) Strong performance: The performance of the mini-host has matured. After several years of exploration and accumulation, most of the mini-hosts can meet the basic needs of office, entertainment, industrial control, display and playback of 70% of users, although most mini-hosts are still designed. However, some high-profile independent mini-hosts are not inferior in overall performance.

(7) Safe and stable: Due to the small size of the mini-host, the high level of motherboard integration, and the design layout of component chips are very compact. Therefore, most mini-hosts can achieve stable operation for a long time, and it is not easy to affect the operation or interruption of the whole machine due to individual hardware problems, or even damage the whole. In the case of the machine, the traditional large desktop host has a large number of hardware overlays, which is prone to compatibility or unstable individual components and affects the operation of the whole machine.

(8) Easy to update and maintain: The mini-host is small and portable, whether it is in software update or hardware update, it is very convenient. If you need to expand the memory hard disk, you only need to open the cover of the mini-host with a screwdriver. The internal motherboard structure and hardware of the chassis are clear at a glance, and the replacement is quite convenient. If the host has problems and needs to be repaired, girls or children, the elderly can easily take out the store or send it back to the factory for repair.

(9) Cost-effective: In addition to Intel’s own micro-PCs are very expensive, the price of other brands’ mini-hosts is very close to the people, generally within 1,000 to 3,000 RMB, the configuration is higher, the price will generally not exceed 5,000 RMB, which to some extent Make a lot of pre-space for DIY users.

Shortcoming of the Eglobal Mini PC

(1) Graphics card: The current soft rib of the mini-host is undoubtedly the problem of the graphics card. As we all know, the single-function display has a large amount of heat. Since the mini-host is born to be small, it naturally sacrifices the performance factor of the main part when controlling the heat. Most of the minis on the market. That’s why the mainframes are all integrated graphics, not alone. Therefore, the mini-host with the set display will be a little difficult when dealing with large gun battle games. Of course, there is no pressure on small single-player games and playing 1080P HD video.

PS: But now, we also have some miniPCs that can hold graphics cards, and can also play LOL. In addition, mini-hosts with unique display have also begun to be launched, but there is still much room for improvement in overall performance coordination.

(2) After sales: There are after-sales problems in the mini-host products. More often, users need to send them back to the factory for repair. Many computer repair shops can’t provide technicians and technical services for mini-host maintenance. Of course, the mini-host market has just opened, and sales always lag behind product sales. It takes time to accumulate technical services. However, as long as you have purchased eglobal’s mini PC, if you have a problem with your mini pc, we can guarantee it for three years. During the effective warranty period, you only need to send your product back, we will repair it for you free of charge.

Introduction to the network RJ45 interface:

RJ45 Port: It belongs to the connector and consists of a plug (connector, crystal head) and a socket (module). The plug has 8 grooves and 8 contacts. It is a network signal connector that is used in network devices.

The difference between RJ45 interface and RJ11 interface:

The RJ45 interface is used for network signals, and the RJ11 is used for telephone signals and fax signals. The former is 8 contacts, the connected network twisted pair cable is 8 wires, and the latter is 4 pins and 4 contacts. The two are very similar in appearance, the former is more bulky, the latter is slightly smaller, and the most accurate distinction is more accurate by using the number of contacts as a reference.

RJ45 interface product application:

RJ45 interface, also known as network interface. Applications include internal LANs, external network connections, and more. Common RJ45 interface products are: network server, routing cat, hub, personal PC terminal, printer and other equipment.

RJ45 interface industry application:

The RJ45 interface is the most used in the network equipment manufacturing industry, computer PC manufacturers, network printer equipment manufacturers, network system installation architecture industry. In the former, the RJ45 interface will be used in the finished product, and some products of the former will be used in the post-architecture network environment.

The complementarity between RJ45 and RJ11 in the era of network e-commerce:

The wide application of RJ45 interface promotes the development and growth of network e-commerce, and a large-scale sales channel before e-commerce is telemarketing or telemarketing. Information in the e-commerce era conveys more accurate, clear and intuitive products through platform and online communication, making up for the void caused by the latter language description.

There are many different models of Eglobal Mini Computers with Gigabit RJ45 LAN port. Users can surf the internet after connecting a RJ45 LAN cable with Eglobal Mini Computers you bought. As technology becomes more developed, the Internet seems to be something that people have to do.

RS232 is a standard interface, which is a D-shaped 9-pin. The signal definition of the interface of the connected device is the same. The RS422/RS485 is a non-standard interface, generally a 15-pin serial interface (also a 9-pin interface), and the pin definition of each device is different. RS232 is a 4-wire system with full duplex mode. RS485 is a two-wire system with half-duplex mode.

RS232 is designed for point-to-point communication (that is, using only a pair of receiving and transmitting devices). The driver load is 3~7kΩ. Therefore, RS232 is suitable for communication between local devices. 422 and 485 serial interface standards, RS232 and RS422/RS485 are different. The data signal adopts differential transmission mode, also called balanced transmission. It uses a bunch of twisted pairs. In the early PC communication, the maximum transmission distance of RS422 is more common. 4000 feet with a maximum transfer rate of 10 Mb/s.

The basic knowledge of RS232 communication: RS232 communication is also called serial communication mode. It refers to the way that the computer uses the serial port cable and the single device (controller) to communicate through the RS232 international standard protocol.

Communication distance: 9600 baud is recommended within 13 meters.

Communication rate (baud rate): The default is 9600 bps, and the common ones are 1200 2400 4800 19200 38400. The larger the baud rate, the faster the transmission speed, but the shorter the stable transmission distance, the worse the anti-interference ability.

The basic knowledge of RS485 communication: The basic communication mechanism of RS485 and RS232 is the same. His advantage is that it makes up for the shortcoming of RS232 communication distance and can not carry out network management of multiple devices at the same time.

The computer connects multiple 485 devices (access controllers) in turn through the RS232 RS485 converter, and polls the devices on the bus in turn.

The wiring label is 485+ 485-, which corresponds to 485+ 485- of the link device (controller).

RS422 has longer distance and faster transmission rate than RS232 transmission. The transmission rate is up to 10Mbit/s. At this rate, the cable length is 120 meters. If the transmission rate is lower, such as 9000 baud rate, the maximum distance can reach 1200 meters. .

RS422 uses two signal lines per channel, if one is in a logic “1” state and the other is a logic “0”. The circuit consists of a transmitter, a balanced connection cable, a cable termination load, and a receiver. It is stipulated in the circuit that there is only one transmitter and there are multiple receivers, so the point-to-point communication method is usually adopted.

Basic knowledge of RS422 communication: His communication principle is similar to RS485. The difference is that his bus is two sets of twisted pairs (4 lines), which are respectively labeled as R+ R- T+ T-. The disadvantage is that the wiring cost is high and it is easy to make mistakes. It is used less now.

Because RS232 COM port is universal, Most of Eglobal Industrial Mini Computer is with the RS232 COM port like the following pictures shown. The Mini PC can support the adapter RS232 to RS422/485 if you need the RS422 or RS485 port.

In general, standard industrial mini pc computers have a rich IO interface. We often see the word “COM” on the side of the industrial computer. What does the COM serial port of the industrial computers mean? What kind of effect? We come to you to understand the knowledge and function of the COM serial port of the industrial computers.

First of all, let’s understand the definition of COM interface: COM port (cluster communication port) is the serial communication port, referred to as serial port. The COM serial products commonly used in IPCs generally have RS-232 and RS-485 interfaces. In appearance, both serial ports use a 9-pin type. It’s just that they have different definitions of the two pins, which are not mentioned here.

The RS-232 serial port used by the COM serial port of the industrial computer is relatively more. RS-232 (ANSI/EIA-232 standard) is the standard for serial connection on IBM-PC and its compatible machines.

The COM port is a communication port that can be used in a wide variety of communication devices.

Pin function of the 9-pin serial port:

1 Carrier Detection (CD)

2 Accepted Data (RXD)

3 Send Data (TXD)

4 Data Terminal Ready (DTR)

5 Signal Ground (SG)

6 Data Ready (DSR)

7 Request to Send (RTS)

8 Clear Send (CTS)

9 Ringing Indication (RI)

The COM port is a communication port that can be used in a wide variety of communication devices.

1. Hospital medical equipment control: hospital gastro scope, CT, chest X-ray instrument, etc.

2. Supermarket charging related equipment: small ticket printers, credit card machines, barcode grabs, etc. for supermarkets.

3. Engineering production design control: PLC programmer

4. Computer extended peripheral equipment: such as printer, serial mouse, serial keyboard, etc.!

5. Printing device: printer

6. Weighing equipment: electronic pounds

7. The industrial control COM serial port also has a connection card module, a sensor, a mouse, a modem, etc., and can also be connected to industrial instruments and meters.
