The Samsung M310 is small in size. It uses DLP projection and LED light source technology. The standard resolution is 800×600, with 150 lumens brightness and 1000:1 contrast ratio, and it has D-sub and composite video interface. The release date and price have not been announced yet, and the problem of lower brightness is still the biggest bottleneck in the popularity of LED light sources.
POE (Power Over Ethernet) refers to the use of IP-based terminals (such as IP phones, wireless LAN access points AP, network cameras) without any changes to the existing Ethernet Cat.5 cabling infrastructure. Etc.) While transmitting data signals, it can also provide direct current technology for such devices. The POE Switch is a switch that supports Power over Ethernet.
The POE switch port supports an output power of 15.4W or 30W, which complies with the IEEE802.3af/802.3at standard, and supplies power to standard POE terminal equipment through network cable power supply, eliminating the need for additional power wiring. In line with IEEE802.3at POE switch, the port output power can reach 30W, and the power available to the powered device is 25.4W. In layman's terms, a POE switch is a switch that supports network cable power supply. It can not only realize the data transmission function of ordinary switches, but also Supply power to the network terminal.
POE (Power Over Ethernet) refers to the use of IP-based terminals (such as IP phones, wireless LAN access points AP, network cameras) without any changes to the existing Ethernet Cat.5 cabling infrastructure. Etc.) While transmitting data signals, it can also provide DC power supply technology for such devices. POE technology can ensure the normal operation of the existing network while ensuring the safety of the existing structured cabling, reducing costs to the greatest extent.
