1、CH9120 CHIPSET: Equipped with the original CH9120 chip, this Ethernet Adapter Module features an Ethernet MAC and PHY. The operating mode, port, IP and other network parameters of the chip are set through the host software and serial port commands. 2、BIDIRECTIONAL DATA TRANSFER: Capable of facilitating bidirectional transparent data transfer between 485 serial and RJ45 Ethernet ports, this module supports both 10M connections and both full duplex and half duplex operating. Compatible with IEEE 802.3 protocol. 3、AUTOMATIC LINE CONVERSION: The Ethernet module features MDI MDIX automatic line conversion, allowing for easy connection with either crossover or straight through cables without manual adjustments. 4、FLEXIBLE NETWORK CONFIGURATION: CH9121 serial to Ethernet adapter module supports 4 work modes: TCP CLIENT, TCP SERVER, UDP CLIENT, and UDP SERVER. The KEEPALIVE mechanism is supported. The serial port baud rate ranges from 300bps to 150000bps. 5、ROBUST SURGE GUARD WITH TVS: The onboard Transient Voltage Suppressor (TVS) can effectively suppress the surge voltage and transient peak voltage in the circuit, and protect the rear circuit and equipment. 6、LIGHTNING GUARD WITH GDT: Featuring a Gas Discharge Tube (GDT), which can be used to discharge the powerful lightning current into the earth, so that the subsequent circuit and equipment can avoid being damaged by the surge impact. 7、ENHANCED SIGNAL STABILITY: The onboard digital isolator has excellent performance to isolate the signal and make the transmitted signal more stable. Onboard power supply isolation provides stable isolation voltage and output short circuit guard, and no additional power supply is required at the isolation end.
