• Original Industrial Grade Chip---Adopt original CH343G inside, fast communicating, stable and reliable, better compatibility. CH343G USB TO RS232/485/TTL Interface Converter, Industrial Isolation. With Aluminium Alloy Enclosure,Solid and durable.
• Safer Isolated Design--- Onboard unibody power supply isolation, provides stable isolated voltage, needs no extra power supply for the isolated terminal; Onboard unibody digital isolation, allows signal isolation, high reliability, strong anti-interference, low power consumption.
• Multi-protocol & Multi-type Conversion---USB to RS232, RS485 or TTL(UART); RS232, RS485 or TTL(UART) to USB. Note: only one of the RS232, RS485, and TTL can be converted to USB at the same time; And RS232, RS485, and TTL cannot be converted between each other; RS232, RS485 and TTL can be received at the same time but cannot be sent at the same time; RS232, RS485 and TTL cannot be converted to each other, but USB to RS232, RS485 or TTL is supported.
• Multiple Protection, Safe And Stable---Onboard TVS (Transient Voltage Suppressor), effectively suppress surge voltage and transient spike voltage in the circuit, lightningproof & ESD protection. Onboard self-recovery fuse and protection diodes, ensures the current/voltage stable outputs, provides over-current/over-voltage proof, improves shock resistance.
• Multi system Support---Supports Mac, Linux, Android, Windows 11 / 10 / 8.1 / 8 / 7, etc. Working Status Indicators: Onboard 3 LEDs for indicating the power and transceiver status. Fully automatic transceiver circuit with no delay, ensures the USB port communicates with different interfaces fastly and stably, without interfering each other Onboard TTL serial 3.3V/5V voltage translator, config the TTL level via switch. High quality USB-B and RS232 connectors, smoothly plug/pull.
