In such a situation, not only in the PC and mobile areas, but also in the projection industry has become one of the problems to be solved. The dilemma that many devices need to use different types of wire to synchronize with projectors has existed in the industry for a long time. Nowadays, microwhale projectors have brought new technological breakthroughs and become the first brand to support the wireless projection of windows platforms. In terms of support, the Micro Whale not only supports airplay, but also supports many functions such as DLAN and miracast, which is convenient for users to perform multi-device screen-cast operations. In terms of device support, the Micro Whale Projector is also fully compatible with IOS11, and supports all platforms that use Windows. Its new "Office Screencast" feature also makes operation more convenient, and it can be easily completed in a few simple steps. ,Very convenient, Simple setting, remote screen shooting is more convenient In the same industry, there are many manufacturers that do projection functions. However, most projectors use mobile devices, local devices, or external hosts to implement the projection screen. Even some projectors that support wireless projection require cooperation. Some app to achieve. Scanning two-dimensional code, downloading, registration, binding and other cumbersome operations, as well as the possibility of error, the experience is very unfriendly. The wireless video screen application launched by this micro-whale not only operates more easily, but also realizes a remote screen-casting function. It can adapt to more occasions in the use scenario, undoubtedly combing new standards for the entire industry. To achieve this function, you only need to upgrade the current device, upgrade the Whale Projector to WUI02.02.00 or later, search for and download the wireless projection software in the built-in application store, and restart the projector according to the operating instructions. The screen-casting function can be realized, and the options in the interface can also help us to easily select each platform. When using the screencast function in a device equipped with a Windows system, you only need to open the office.whaley.cn webpage in the Chrome browser to complete the operation. Enter the matching code according to the operation prompts to easily achieve the screen-casting function. Remote Screening, a pioneer of new features Due to the special nature of the shooting mode of the micro whale, it can get rid of local area network restrictions, and can easily complete the remote screen operation. Even if it is a usage scenario such as a remote conference, it can be easily screened by the micro whale projection without fear of distance. , Convenient and quick completion of screen-casting operations, who have opened up new areas in the industry. Through the technological innovation of the micro-whale, in the actual screen-casting experience, the mosaic and Caton phenomenon appearing in the old-fashioned projection airplay, DLAN protocol almost never appeared on the micro-whale projection, and the stability has also greatly improved. Microwhale projection has become a leading brand in the entire industry since its establishment. Through precise grasp of the market and attention to user suggestions, the microwhale has discovered the inconvenience of data projection via the HDMI2.0 interface, and continues to explore. The new possibility of wireless projection screen, finally launched a wireless projection screen. At the same time, it supports the latest ios11 operating system, whether it is Android, Apple mobile phone or windows computer, can easily use the micro whale shooting function, interactive screen size greatly reduced, at the same time benefit from the small whale projection High saturation and color management of the picture, the projection picture is more vivid and lifelike. The future of projection, more futuristic technology The wireless projection launched this time has got rid of the limitations of the past. It is no longer only the airplay protocol. At the same time, it has adapted support for more platforms such as windows, and the long-range screen-casting function has also completely dropped the industry’s perception of the screen-casting function. The micro-whale proved his strength in this industry again with actions. Thanks to the powerful hardware R&D capabilities of the micro whale and its grasp of the market, the micro whale projection platform on JD.com is also welcomed by more consumers. It is believed that with the addition of more functions, the micro whale will also make our life easier. And work becomes more convenient.

Apple introduced the airplay protocol, but because of Apple's closed strategy and limitations, airplay can only upload video to devices that support airplay. It is extremely inconvenient to use, and it is not supported by most of our Windows devices. 
Smart TV/box information can focus on smart TV information network sofa butler (http://), China's influential TV box and smart TV website, providing information, communication, TV boxes, smart TVs, smart TV software, etc. Answering questions.
1. Origin:
2. The name RJ stands for the registered jack and is the USOC (universal service ordering codes) code of bell system. USOC is a series of registered sockets and their wiring mode, which are developed by bell system to connect the user's equipment to the public network. FCC regulations control the application of this purpose. The FCC (Federal Communications Commission) issued a document on behalf of the U.S. government to specify RJ11.
3. RJ11 is the common name of the connector developed by Western Electric Co. Its shape is defined as a 6-pin connecting device. Originally called wexw, where x means "active", contact or needle. For example, we6w has all six contacts, numbered from 1 to 6. The we4w interface only uses four pins, the outermost two contacts (1 and 6) are not used, and we2w only uses the middle two pins. For RJ11, the information source is contradictory. It can be a 2 or 4-core 6-pin connector. What's more confusing is that RJ11 is not only used to represent the 6-pin connector, it also refers to the 4-pin version.
4. RJ45 and RJ11: different standards, different sizes
5. Due to the different sizes of the two (RJ11 is 4 or 6-pin, RJ45 is an 8-pin connection device), it is obvious that the RJ45 plug cannot be inserted into the RJ11 socket. However, it is physically feasible (RJ11 plug is smaller than RJ45 jack), which makes people think that they should or can work together. It's not. It is strongly recommended not to use RJ11 plug for RJ45 socket.
â’ because RJ11 is not internationally standardized, its size, insertion force, insertion angle, etc. are not in accordance with the international standard connector design requirements, so interoperability cannot be guaranteed. They even cause damage to both. Since the RJ11 plug is smaller than the RJ45 socket, the plastic parts on both sides of the plug will damage the metal pin of the inserted socket.
RJ - 45 port is our most common port, it is our common twisted pair Ethernet port
Because twisted pair is mainly used as transmission medium in Fast Ethernet, RJ-45 port can be divided into 10Base-T network RJ-45 port and 100base TX network RJ-45 port.
Among them, the RJ-45 port of 10Base-T network is usually identified as "eth" in the router, while the RJ-45 port of 100base TX network is usually marked as "10 / 100btx". This is mainly due to the fact that most products of Fast Ethernet router still adopt 10 / 100Mbps bandwidth adaptive.
The left figure shows the RJ-45 port of 10Base-T network, while the right figure shows the RJ-45 port of 10 / 100base-tx network. In fact, the two RJ-45 ports are exactly the same in terms of the port itself, but the corresponding network circuit structure in the ports is different, so they can not be connected casually.
Definition of RJ45 interface pin signal
Ethernet 10 / 100Base-T interface:
1 TX + tranceive data +
2 TX - tranceive data -
3 RX + receive data +
4 N / C not connected
5 N / C not connected
6 RX - receive data
7 n / C not connected
8 N / C not connected
Ethernet 100base-t4 interface:
1 TX_ D1 + tranceive data +
2 TX_ D1 - tranceive data
3 RX_ D2 + receive data +
4 BI_ D3 + bi directional data +
5 BI_ D3 bi directional data
6 RX_ D2 - receive data
7 BI_ D4 + bi directional data +
8 BI_ D4 bi directional data
Note: RJ45 interface adopts differential transmission mode, TX + and TX - are a pair of twisted pair, which can reduce interference when twisted together.
