Introduction

AI Translation

CH9120 is a chip that realizes transparent transmission between network and UART. It integrates TCP/IP protocol stack, which can realize bidirectional transparent transmission between network data packets and serial data. It has 4 working modes: TCP CLIENT, TCP SERVER, UDP CLIENT and UDP SERVER. The baud rate can be up to 921600bps. It can be easily configured by upper computer software or serial commands, which is convenient and quick.

CH9120 is a chip for transparent transmission between network and UART, which can realize the bidirectional transparent transmission of serial data and network data. It supports 4 working modes (TCP CLEINT/SERVER, UDP CLIENT/SERVER), and the baud rate supported ranges from 300bps to 921600bps. Before use, the network and UART parameters of the chip shall be configured by the upper computer software NetModuleConfig. Exe or the serial command. After the configuration is completed, CH9120 will save the configuration parameters to the internal storage space. And after the chip is reset, CH9120 will work according to the saved configuration value.

The basic parameters of CH9120 include: name, MAC address display, automatic access IP address setting, manual IP address setting (including CH9120 IP address, subnet mask, default gateway), and UART negotiation configuration.

The name is mainly for the convenience of CH9120 module management within the LAN, with the length of not more than 20 bytes. The MAC address field shows the MAC address of the currently selected module. There are two ways for CH9120 to set network parameters. 1) DHCP, that is, it automatically obtains network parameters from the gateway device with DHCP SERVER function; 2) manual setting. UART negotiation configuration function is to enter the serial configuration mode by handshaking through UART, which is disabled by default.
