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. 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. 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. DIGITAL ISOLATION, DIRECT CURRENT DIRECT CURRENT POWER ISOLATION: Onboard digital isolator ensures signal integrity and stability through effective signal isolation. Provides stable isolated voltage and short circuit prevention, with no additional power supply needed for isolated terminals.
