In the early 1990s, when DMX was first introduced on the lighting system, the DMX's lamp channel was 4-6, and now the lamp channel has been implemented 30-40, so each port will not support too many lights. About a dozen. In order to solve this problem, there are many transmission protocols on the market. The most popular ones are Artnet and StreamingAeN.
If DMX is most suitable for no more than 12 output ports, like the MA console, its output port is about 12, but up to 64 output ports can be achieved through Ethernet transmission. With Ethernet, it can be applied more widely and flexibly in large projects. The cable used for Ethernet is much cheaper than the DMX line we use today, so we can save it by using it for large projects. It can also be designed and controlled on a computer via Ethernet, and it takes a lot of manpower to use the DMX line.
Another new protocol is the RDM we often talk about, namely remote distribution control. Professional brand lights in the international market are now applied to RDM technology, because RDM makes it easier to set up.
RDM control can install a software on the computer interface, and directly see the situation on each light. If the light bulb is broken or the temperature is too high, it can be directly transmitted to the computer through RDM. Problems can be solved directly by the computer, no need to arrange a person to do, so the application of RDM is more popular internationally.
The application of RDM does not require additional controllers, and these protocols are directly supported on the professional console. Therefore, when selecting products, pay attention to the protocols supported by the lights. We recommend the protocols that support DMX and Ethernet and RDM. This is a very important development trend in the future.
In some international markets, they like to do it through wired and wireless, which makes the installation process easier and more convenient. They are popular in both European and American TV stations. Some lights can be transmitted via DMX, and some will be applied to wireless transmission systems.
Let's briefly introduce the RDM transport protocol. The above picture mainly demonstrates the three output ports of DMX. It is a complete system port through wireless and wired. This is an RDM software display interface. If you support RDM software, you can directly click to see the channel of each light. Values ​​and parameters, if your light supports RDM, the software interface can save you time and quickly solve the problems encountered on the lamp.
This picture is for complex projects. It can be seen from the figure that there should be many lights and many output ports in the performance and engineering. The biggest difference from the simple project is the Ethernet distributor in the middle. If you need to use 20 output ports or more ports in a large show, you can use the Ethernet splitter, because there are many lights that need to be controlled by a single point. This system combines RDM, Ethernet, and DMX control. A set of such systems will be much lower in cost. The development of future lights needs to support Ethernet, DMX, and RDM.
Nowadays, the matrix lights, each lamp bead controls the color of the lamp through 4 channels. If it is calculated according to 36 lamp beads, one lamp will have more than one hundred channels, which is not the channel to be occupied by other effects. Imagine a DMX signal cable can only be connected to two lights. Although wireless DMX and Ethernet modules do not increase in cost, you need to have these features, and new transport protocols will become more popular and gradually replace the old transport protocols.
In Europe and the United States, wireless devices are widely used in venues and TV stations. Now they are gradually being promoted to domestic TV stations. In fact, they can also try them in China. Many people are worried about whether there will be interference in wireless transmission. Now wireless devices support two different frequency bands of 2.4GHz and 5.8GHz to avoid interference.
Fiber Optic Cable Channel Assembly
An optical fiber trough is a cable trough for laying soft optical fibers. Material general points: flame retardant engineering plastics, aluminum alloy, steel several. Width is 120mm, 200mm, 240mm, 300mm, 340mm, 400mm, height is generally 100mm. Other sizes can be customized by manufacturers in case of mass purchase. Generally, it is used for wiring in indoor machine rooms.
Classification of optical fiber troughs
1. Plastic optical fiber trough
Plastic fiber groove is a new product developed according to the requirements of high standard machine room construction, absorbing the advantages of foreign products combined with China's national conditions. The groove body and fiber outlet and other accessories are made of high-quality flame retardant materials, good integrity, simple installation, corner corner protection, to ensure that the bending radius of the fiber is greater than 40mm; The fiber outlet is made of flame-retardant plastic and protected with rounded corners. It can be moved freely in the tank to facilitate fiber laying in the appropriate position.
2. Aluminum alloy optical fiber trough
Aluminum alloy fiber groove is designed and manufactured for the various environments and places used in fiber groove, as well as the wishes of customers at home and abroad. It is a new type of fiber groove required by high standard machine room.
The main channel and the column channel are assembled by special aluminum alloy profiles, the surface is chemically treated, and the bottom plate of the channel body is often aluminum plastic plate, which is neat and beautiful. The optical fiber trough can also be separately installed on the cable tray.
Fiber Optic Cable Channel assembly is an essential component of fiber optic networks. It is used to protect and manage fiber optic cables, ensuring that they are properly installed and maintained. This assembly is designed to protect fiber optic cables from environmental factors such as moisture, dust, and temperature changes, which can cause signal loss and degradation.
A fiber optic cable channel assembly typically consists of a channel, a cover, and mounting hardware. The channel is a long, narrow structure that is designed to hold multiple fiber optic cables. It is usually made of metal or plastic and can be mounted to a wall or other structure. The cover is used to protect the cables from external factors and can be made of a variety of materials, including plastic, metal, or fiberglass.
The mounting hardware is used to secure the channel and cover to a wall or other structure. It typically includes screws, bolts, or other fasteners that are designed to hold the assembly in place. Some fiber optic cable channel assemblies also include cable ties or other devices that are used to secure the cables inside the channel.
Fiber optic cable channel assemblies are used in a variety of applications, including telecommunications, data centers, and industrial environments. They are particularly useful in environments where space is limited or where cables need to be protected from external factors. For example, in a data center, fiber optic cable channel assemblies can be used to organize and protect cables running between servers and other equipment.
