Industrial wireless access point is a wireless switch used for industrial field wireless networking. At present, the main technology is 802.11 series, and the whole protocol is 802.11, 802.11a\b\g\n and so on. Industrial wireless access node (session point or access bridge): is a very wide name, which includes not only a simple wireless access point (wireless AP), but also a wireless router (including wireless gateway, wireless bridge) A general term for such devices.
The explosion-proof wireless Access Point series includes explosion-proof wireless AP, explosion-proof DTU, explosion-proof network bridge, and explosion-proof router. Be suitable for all kinds of petrochemical, electric power, Underground Pipeline and other dangerous production operation scenarios. The explosion-proof grade has two series of Exd IIB T6 and Exd IIC T6. Maxon's products are made of 304 stainless steel and support Ceiling or pole installation. It has a free-remove-cover design. The whole machine meets the IP68 waterproof rating.
Industrial Ethernet switches, which are used in industrial control field, are open and widely used due to the adopted network standards. They can adapt to low temperature and high temperature, resist electromagnetic interference, prevent salt spray and have strong earthquake resistance. Industrial Ethernet switches use a transparent and unified TCP/IP protocol, and Ethernet has become the primary communication standard in industrial control.
The serial port networking server is also called serial port server. The two keywords are serial port and network. The network is divided into two types: internal network and external network. The internal network generally refers to Ethernet, and the external network refers to the Internet. It is an effective means for communication on a global scale. Before the network is popular, data exchange is usually carried out between the device and the computer through simple RS232; if long distance transmission is required, RS485 can also be used (normal RS485 can transmit 1200 meters, industrial grade can transmit 5000 meters).
