Introducing the CH9120 Ethernet Network Module, a powerful solution designed to seamlessly connect RS232 serial ports to RJ45 Ethernet networks. This versatile module supports a baud rate range from 300bps to 150000bps, making it ideal for various applications in industrial automation, data acquisition, and remote monitoring. Original Chipset with Bi-Directional Transmission: The CH9120 module utilizes the original CH9120 chip, which incorporates an Ethernet Media Access Control and Physical Layer (PHY). This ensures seamless, bi-directional transparent transmission of RS232 serial data and RJ45 Ethernet data, providing reliable communication for your devices. Adaptive Interface with MDI/MDIX Auto Switching: This module supports both 10M full duplex and half duplex Ethernet interfaces, fully compliant with the IEEE 802.3 protocol. The adaptive interface automatically detects and switches between crossover and straight-through Ethernet cables, simplifying connectivity and reducing setup time. IP and DNS Support for Easy Configuration: The CH9120 module supports DHCP for automatic IP address allocation, making network integration straightforward. It also enables DNS domain name access, allowing for easy configuration of chip working modes, ports, IP addresses, and other network parameters via host software or serial commands. Versatile Operating Modes and Baud Rate Range: This module supports four operational modes: TCP CLIENT, TCP SERVER, UDP CLIENT, and UDP SERVER, along with a KEEPALIVE mechanism to maintain connections. Its compatibility with a wide baud rate range (300bps to 150000bps) ensures it meets the diverse needs of various applications. Protecting Features for Enhanced Safety: The CH9120 is equipped with onboard TVS (Transient Voltage Suppressor) to suppress surge voltages and transients, protecting downstream circuits and devices. Additionally, it features an onboard GDT (Gas Discharge Tube) that safely diverts excess currents to ground, ensuring the safety and longevity of your equipment. Digital Isolation for Signal Integrity: With an onboard digital isolator, this module guarantees signal integrity and stability through effective signal isolation. It provides stable isolated voltage and prevents short circuits, eliminating the need for an additional power supply for isolated terminals. The CH9120 Ethernet Network Module is the perfect choice for those seeking a reliable, flexible, and easy-to-configure solution for connecting RS232 devices to Ethernet networks. Enhance your connectivity and ensure robust communication with this advanced module, designed to meet the demands of modern applications.
