Abstract

The invention discloses a router. The router comprises a core board and an interface board, wherein a routing master control chip is embedded in the core board, and a first SPI interface, a first RS232 interface, a first power supply output interface, a first power supply input interface and a first USB interface are arranged on the core board; a serial port conversion chip is embedded in the interface board, and a second SPI interface, a second RS232 interface, a second power supply input interface, a second power supply output interface, a second USB interface and an RS485 / 422 interface are arranged on the interface board; the serial port conversion chip is electrically connected between the second RS232 interface and the RS485 / 422 interface. The core board is electrically connected with the interface board, and meanwhile, the RS485 / 422 interface is arranged on the interface board, and the serial port conversion chip is embedded in the interface board, so that the second RS232 interface is converted to the RS485 / 422 interface, and the problems that the conventional router is single in function and limited in expandability are effectively solved.

Description

technical field [0001] The invention relates to the field of network equipment, in particular to a router. Background technique [0002] A router (Router), also known as a gateway device (Gateway), is used to connect multiple logically separated networks. The so-called logical network represents a separate network or a subnet. When data is transferred from one subnet to another, it can be done through the router's routing function. Therefore, the router has the function of judging the network address and selecting the IP path. It can establish flexible connections in a multi-network interconnection environment, and can connect various subnets with completely different data packets and media access methods. The router only accepts information from the source station or other routers, and is an interconnection device at the network layer. [0003] As a type of router, a wireless router is like an extended product that combines a simple wireless AP (Access Point, commonly kn...
