Thanks a lot for our customers’ support. Of course we provide 3 years warranty for Eglobal Mini PC. Details about our Warranty Policy here:
But we received
some defective motherboard operated wrongly by our customers because they don’t
apply the thermal paste on the motherboard correctly.
Here is the right
tip referring to the picture of motherboard:
CPU onboard is
back of the motherboard and located in the green line, it is CPU lens in the
red line. The thermal paste cant cross the red line and not too much or thick
when you apply. Otherwise it will cause a short circuit on the motherboard. So
you must evenly apply the thermal paste on the CPU lens.
Have you ever encountered such a problem, why my mini computer network card speed is always 100 Mbps, and it refuses to work at 1 Gbps Speed, just like the following picture（example for S200）:
There are some way to let you know what went wrong.
Method 1: If the lan network card support 1Gbps, you
may use at least CAT5E or CAT6E network cable.
Method 2: Connect your cable directly to the network port of the mini PC. This method can test whether it is your computer problem or router problem. If the machine connected to the network cable can reach 1 Gbps, then consider whether your router is compatible. If the router is not compatible, you need to change it.
Method 3: select ” Auto Negotiation ” as the
picture we attached:
Under normal circumstances, our computer will
automatically adapt to the network speed, no need to set, but in this case, you
can set or check here.
If there is no problem with the above points, the
network speed problem still exists, then contact us, we will help you solve it.
At
present, in the twisted-pair this family, Cat.5/CAT5E/CAT.6/ CAT6e cable types of these twisted-pair lines are
the most widely used, CAT.7 are also followed, then what are the differences
between them?
What are the Cat.5 and CAT5E?
CAT5, this type of cable increased the winding
density, coat a high-quality insulating material, the outer skin will be
labeled “CAT5”, transmission bandwidth of 100MHz, for voice
transmission and the highest transmission rate of 100Mbps data transmission,
mainly used for 100BASE-T and 10BASE-T network. This is the most commonly used
Ethernet cable. “CAT7” refers to the CAT5E of unshielded twisted pair
(Utp-unshielded Twisted Pair), non-shielded twisted-pair cable is composed of
many pairs of twisted-pair wire and a plastic sheath, the outer skin labeled
“CAT5e”; transmission bandwidth up to 1000Mb/s, However, it is often
necessary to rely on the support of expensive special equipment. As a result,
it is often used only in Fast Ethernet of 100Mb/s to enable desktop
switch-to-computer connectivity.
CAT5
The difference between CAT5 and CAT5E.
The identification of class five lines is “CAT5”,
bandwidth 100M, suitable for networks below hundred megabytes, the
identification of super five lines is “CAT5E”, bandwidth 155M. CAT5 can
meet the increasingly popular 100M/bps Ethernet, CAT5E is mainly used in
gigabit network, but now also common applications in the LAN. CAT5 transmit
signals with a maximum rate of 100MHz and are widely used. Ultra CAT5 transmit
signals with a maximum rate of 100MHz, better performance than five lines,
improved metrics such as NEXT, PS-ELFEXT, Atten, and support for duplex
applications.
CAT5E
CAT5E mainly used for communication companies or network
companies to deploy outdoor short distance links. The maximum effective
communication distance of the CAT5 is 100M, and the maximum communication
distance of the CAT5E is 300M. And the outer protective layer has a much longer
service life than the CAT5. Most of the lines connected to your router or
switch from the small zone gateway or the entire building network are CAT5E.
While super five types of unshielded twisted-pair wires can also provide up to
1000Mb/s transmission bandwidth, they often require the support of expensive
special equipment. As a result, it is typically applied only to 100Mb/s Fast
Ethernet, enabling desktop switch-to-computer connectivity.
The difference between CAT5E and CAT6.
As people’s need for
higher bandwidth and faster speed networks continues to grow, CAT5E and CAT6
are increasingly being used in people’s lives. At present, in the twisted-pair
line of this family, compared with CAT3, CAT5 and CAT7 and other twisted-pair
lines, CAT5E and CAT6 two twisted-pair lines are the most widely used range.
Although the status of CAT5E and CAT6 is at hand, this does not mean that CAT5E
and CAT6 can replace each other. Consumers still need to master the
characteristics of each of the two, in order to make a better purchase
according to their own network needs. So what are the differences between CAT5E
and CAT6? First of all, the biggest difference between CAT5E and CAT6 is the
difference in their performance. While both the CAT5E and CAT6 systems can
transmit gigabit networks, the standard used by the CAT5E system to transmit
gigabit networks is 1000Base-T, while 1000BASE-Tx is the way CAT6 systems work.
From this point of view, the CAT5E system is only “able” to support
Gigabit Ethernet, and the CAT6 system is a “truly guaranteed” use of
Gigabit Ethernet.
CAT6
As a
result, the CAT6 system is better adapted to the current building environment,
especially in places where a large number of twisted-pair wires are
concentrated and have many sources of interference, such as rooms with many
electrical appliances (computers, telephones, various production equipment,
etc.), devices, adjacent to power lines, lighting wires. Secondly, in the structure,
there are obvious differences between CAT5E and CAT6. The CAT6 adds an
insulated cross skeleton, placing four pairs of twisted-pair wires in four
grooves of the cross skeleton respectively, and the cable has a large conductor
diameter, small torque and a thicker outer diameter. This central cross new
production process is also designed to avoid crosstalk between cables when
applied to 1000BASE-T networks.
The difference between CAT6E and CAT6.
CAT6E
Since
the release of the TIA-568C.2 standard in 2009, CAT6E has been widely used in
various wiring systems. Compared with traditional CAT6, CAT6E has a higher
transmission frequency and rate. In general, the bandwidth of the CAT6 is
250MHz, and the bandwidth of the CAT6E is twice times that of it, which is
clearly a very good solution for a data center with high network bandwidth
requirements. As the CAT6E of the current cabling system darling, supply will
make a comparison with the traditional CAT6. At present, the number of 10G
network ports in the data center is increasing, in the 10G Ethernet interface
mode, 10GBase-T four pair of twisted wire is one of the most familiar ways we
currently know. CAT6E is now used in data centers, with the further expansion
of data center construction, the scale of use of CAT6E will be further
expanded. It should be noted, however, that although CAT6E has a superior side
to other cables, it also has its drawbacks and shortcomings. In the wiring, not
blindly according to the performance of the advantages and disadvantages to
choose, but according to the actual situation to choose the appropriate wiring
system for their own.
What is the Cat.7
The
CAT7 standard is a set of standards that support up to 600MHz bandwidth
transmission wiring on a 100 ohm twisted-pair line. CAT7 is a 8-core shielding
line, each pair has a shielding layer (generally metal foil shielding DINTEK),
and then 8 cores outside there is a shielding layer (generally metal braided
screen shielding DINTEK), the interface and the current RJ-45 is not compatible.
CAT7
The difference between CAT7 and CAT6.
There
are many notable differences between CAT7 and CAT6, most notably bandwidth,
cat5e has a higher transmission bandwidth (at least 600MHz) compared to CAT4,
CAT5, CAT6, and CAT7, The CAT6 channel provides at least 200MHZ of
comprehensive attenuation to crosstalk ratio and overall 250MHZ bandwidth, and
the CAT7 system can provide at least 500MHZ of comprehensive attenuation to the
overall bandwidth of the crosstalk ratio and 600MHZ. Another difference between
the CAT6 and CAT7 systems is their structure. CAT6 can use both UTP and STP,
while CAT7 is based only on shielded cables. Each pair of lines in the CAT7 has
a shielding layer, and the four pairs of lines together also have a large
public shielding layer. In terms of physical structure, the additional
shielding layer allows the CAT7 to have a larger line diameter. Another important
difference is its ability to connect hardware, the parameters of the CAT7
system require the connection head at 600MHZ when all line pairs provide at
least 60DB of integrated proximal string winding, while the CAT5E system only
requires that the value of 43DB,CAT6 in 250MHZ be provided at 100MHZ as 46DB.
Finally,
it needs to be explained that regardless of the use and purchase of that
product, it is necessary to understand the principle of the barrel, that is, the
use of the network rate of the online is how much, remember that
high-performance products can be backward compatible, in turn not. Then home
use of the network speed limit is the rate of the network card, in other words,
the rate of the network card is how much, the network line is how much.
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.

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! In recent years, in the process of digitalization, networking,
intelligence and multimedia, the universities have adopted mini-hosts as the
equipment for multimedia classrooms.
(6) Download
machine: The characteristics of the download machine, the mini-host is more
than nothing: small size, power saving and good heat dissipation, 24 hours
stable operation is no longer a problem.

and electronic whiteboards.
(8) Shangchao,
government, medical, military and other fields.
Nowadays, the mini
pc can realize dual-screen or three-screen display. It can sell stocks and play
games. It has far exceeded the basic performance originally pursued by the mini
pc. I believe that with the continuous advancement of technology, I believe
that the eglobal mini pc will create more surprise products for users.
In the new retail
industry, there are some industrial mini pc for project needs that can be

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.
RJ45 interface
manufacturers of various types of products:
Mouth 1: orange
blue green brown, light color in front, three five exchange
Mouth 2: white
orange, white green blue, white blue green, white brown brown
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:
