How can we understand the electrical wiring of so many cables ?, So many electrical wiring
Whose lines are not messy? As long as you have mastered the wiring rules, you can understand the line.
What is the wiring rule?
Generally, construction from the end of the line to the end of the line is recommended. Specifically, wiring starts from the lamps or sockets at the last end, so that each wire along the line is collected to the distribution box and di

Wiring, should be in accordance with the current national standards, "Fire automatic alarm system Design Code", the type of wire, voltage grade check. Fire automatic alarm system transmission line and 50V power supply control line, should be used voltage grade not less than AC 250V copper core insulated conductor or copper conductor cable. The AC 220/380v pow

combination of two single laminates, each of which has electronic components and cables. Sometimes you need to connect one side of the single line to the other side of the board, this is through the guide hole (). The guide hole is a small hole on the PCB that is filled with or coated with metal. It can be connected to both sides of the wire. Currently, many computer boards use 4-or even 6-layer PCB boards, while graphics cards generally use 6-layer
When dealing with computer networks, it is inevitable that network cables should be used frequently. In fact, the production of Network cables is very simple, that is, to insert the 4-to-8-Core Cable of twisted pair wires into the crystal head according to certain rules, therefore, the materials required for the production of such network cables only need twisted pair wires and crystal heads. The required tools are also relatively simple. Generally, only one dedicated crimping clamp is required.
not available in a single line, only one power supply can be introduced.
For the typical structure of the AT traction network auxiliary partition Institute (SSP), see. In the figure, T is the catenary, F is the positive feeder, PW is the protection wire in parallel with the rail, B is the circuit breaker, SD is the security grounding device, and La is the lightning arrester; ot is the control circuit power supply; Pt is the voltage transformer; at is
About I2C, this is also the previously tangled part. Note.
(For details, refer to: source; Phodal'sBlog)
The I2C (Inter-Integrated Circuit) bus is a two-line serial bus developed by PHILIPS to connect the microcontroller and its peripheral devices. It is a bus standard widely used in the field of microelectronics communication control. > The I2C bus supports any IC production process (nmos cmos, bipolar ). Two-wire-the serial data (SDA) and serial clo

A fully meshed test environment is stricter than a one-to-one environment for throughput, requiring each port in the switch to receive data sent from other ports, as well as sending data to other ports, but 3Com 4900, Shenzhou digital D-link DGS-3308TG and Edimax ES-5800R these three excellent switches remain the same color, d

Two. Draw a simple circuit diagram
2.1 Schematic design process schematic design can be completed according to the following procedure.
(1) Design drawing size Protel 99/schematic, first of all to conceive a good part diagram, design a good drawing size. The size of the paper is based on the size and complexity of the circuit diagram, setting the appropriate paper size is the first step in designing a good schematic diagram.
(2) Set Protel 99/schematic design environment settings
The fire detection and alarm subsystem is the most important part in the fire automatic alarm system and fire-fighting linkage control system. It has the widest distribution of cables, because the fire detection alarm is set to be located in all parts of the intelligent building, and it is compatible with the protection object level.
Therefore, the number of cables (that is, the number of wires) and Connection Methods of the fire detection and alarm subsystem are extremely important, and they a
can we determine which combination?The more difficult the method is, the following are the general principles.(1) The signal layer should be adjacent to an inner electrical layer (internal power supply/formation), and the large copper film of the inner electrical layer should be used to shield the signal layer.(2) The internal power supply layer should be closely coupled with the formation, that is, the thickness of the medium between the internal power supply layer and the formation should be
"practical and advanced" and select a solution based on actual needs and consumption capacity.
2. Start construction
According to our expectation, it is important to purchase and classify all the cables to be prepared, and then add the corresponding labels on both ends of the cables ). Then we will classify the cables on a single route, and then you will get several simple lines and arrange them according to your plan. As for the location where the Integrated Wiring management system is stored

pressure trough provides three types of line slots: 6 p, 8 p, and 4 P, respectively, in the middle of the 8 p slot is our most commonly used to RJ-45 pressure trough, and the 4 P next to the 201711 telephone line pressure trough.
On the back of the 8 p pressure trough of the crimping tool, we can see the tooth-shaped module, which is mainly used to press the eight contacts on the crystal head on the twisted pair wire.
