CH9120 Ethernet Network Module 4 Mode 150Kbps RJ45 Serial Printer

Summary

• ORIGINAL CHIPSET, BI DIRECTIONAL TRANSMISSION: Utilizes the original CH9120 chip, incorporating an Ethernet Media Access Control and Physical Layer (PHY). Achieves seamless, bi directional transparent transmission of RS232 serial data and RJ45 Ethernet data.
• ADAPTIVE INTERFACE, MDI MDIX AUTO SWITCHING: Supports 10M full duplex and half duplex Ethernet interfaces, compatible with the for IEEE 802.3 protocol. Automatically detects and switches between crossover and straight through Ethernet cables, ensuring easy connectivity.
• IP AND DNS SUPPORT, EASY CONFIGURATION: Supports DHCP for automatic IP address allocation and enables DNS domain name access. Configure chip working modes, ports, IP, and other network parameters via host software or serial commands.
• VERSATILE OPERATING MODES, SERIAL BAUD RATE RANGE: Supports four operational modes, TCP CLIENT, TCP SERVER, UDP CLIENT, and UDP SERVER, along with a KEEPALIVE mechanism. Compatible with a baud rate range of 300bps to 150000bps, accommodating various application needs.
• PROTECTING FEATURES: Features onboard TVS (Transient Voltage Suppressor) for suppressing surge voltages and transients, safeguarding downstream circuits and devices. Equipped with onboard GDT (Gas Discharge Tube) to safely divert currents to ground, protecting circuits and devices from surges.
