Waveshare USB TO RS232/485/TTL

USB TO RS232/485/TTL is an industrial-grade USB to RS232/485/TTL isolated converter featuring an authentic FT232RL chip, with built-in power isolation, ADI magnetic coupling isolation, TVS protection circuits, and an aluminum alloy housing design. USB TO RS232/485/TTL is easy to operate with zero-latency automatic TX/RX switching, offering fast communication speed, stability, reliability, and safety. It is suitable for industrial control equipment or applications with demanding communication requirements.

• Supports USB to RS232, USB to RS485, and USB to TTL (UART) communication
• Genuine FT232RL for high-speed, stable, reliable communication with excellent compatibility
• Onboard integrated power isolation providing stable isolated voltage; no external power supply required on the isolated side
• Onboard integrated ADI magnetic coupling isolation for signal isolation with high reliability, strong anti-interference capability, and low power consumption
• Onboard TVS for effective suppression of surge and transient spike voltages, with lightning and ESD protection
• Onboard self-resetting fuse and protection diodes for stable current and voltage output; overcurrent/overvoltage protection with strong surge resistance
• Onboard zero-delay auto transceiver switching circuit for fast, stable communication between the USB port and various interfaces without mutual interference
• Onboard TTL serial port 3.3V/5V level shifting circuit; switchable TTL communication voltage level via toggle switch
• Aluminum alloy enclosure with anodized matte finish and CNC-machined openings — robust, durable, and finely crafted
• 3 external LED indicators for easy monitoring of power status and signal TX/RX activity
• High-quality USB-B and RS232 connector materials for smooth insertion/removal and solid reliability
