The Application of Serial to Ethernet Converter in Intelligent logistics weighing System
To improve the management of logistics goods, A China company adopts an automatic weighing system. The system can realize automatic and reliable measurement data collection, identification, command, etc.
The Difference between the Domestic Router and Industrial Router
Industrial router is a device that utilizes a public wireless network to provide wireless data transmission capabilities to users. Industrial router with high forwarding function and high connection capacity.
What is Industrial serial to Ethernet Converter
Industrial serial to Ethernet converter is a communication device that realizes serial (TTL serial port or RS232/RS485/RS422) data and TCP/IP protocol data to achieve data transmission through the network.
The Firewall of the Cellular Router
The firewall principle of the cellular router has a series of hardware and software components between different network security domains. Through monitoring and restriction, we can shield the private information, structure and operation status externally as much as possible, and selectively accept external access.
What is VPN of the Industrial Router?
VPN virtual private network function is: set up a private network in the shared network, and encrypted communication. VPN is a basic function of the industrial router,
The Principle and Usage of the Serial Device Server
Serial device server, also known as serial to Ethernet converter, It is a terminal server that transmits data through the serial port of TCP/IP server. However, all of these are the same type of devices, which basically link the serial RS232, RS485 or RS422 interfaces to the serial port of serial device server and transmit data to the Ethernet packet.
Features and Application Scope of the Industrial Router
Industrial router is a kind of wireless communication router of the IoT. The design fully meets the requirements of industrial standards and industrial users. It uses high-performance industrial 32-bit communication processor, multi-dimensional detection software and multiple-protection mechanism hardware to improve the stability of equipment.
What are the Environmental Requirements for the Installation of Cellular Routers?
Installation of cellular routers usually has no special requirements and can be placed on walls or tables in any space. But in order to ensure the best performance of cellular routers, it is better to choose a suitable place. For the installation of cellular routers, it is best to meet the following points:
The Principle of CHAP Encryption for Industrial Routers
The industrial router's PPP protocol supports CHAP and PAP (Password Authentication Protocol). The CHAP protocol is more secure than PAP because of encrypted communication and timing verification. CHAP is commonly called the Challenge Handshake Authentication Protocol.
GRE and IPSEC for Industrial VPN Routing
Two protocols of GRE and IPSEC are common VPN encapsulation protocols in 3G routers. GRE VPN, Generic Routing Encapsulation, encapsulates datagram for certain network layer protocols (such as IP and IPX) so that these encapsulated datagram can be transmitted in another network layer protocol (such as IP).
