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.

(2) Family entertainment / living room audio and video: The compact and compact appearance of the mini-host, combined with its more powerful features than the TV box, has been well received by audio-visual entertainment users.

(3) Industrial control: In this era of looking at the value of the face, the large and rough chassis design of the traditional industrial computer will be gradually replaced by the mini-type industrial computer. The function is no longer the only choice for the industrial computer users.

(4) Cloud terminal: The mini host can be used as an access terminal device for diskless workstations. My users save more maintenance costs and ensure the security of user data resources.

(5) School Education / Multimedia Classroom: The mini-host can provide perfect support for teaching programs, such as resource acquisition, cyberspace, and shared services. The modernization of teaching methods requires more modern teaching equipment to help!

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.
