USB 2.0 To RS485 Converter

Product Details Industrial USB To RS485 CH340 Converter Upgrade Converter Compatibility Standard RS-485 Connector Board Module Highlights: • All original chips are used! • Industrial protection: TVS transient suppression protection, electrostatic ESD protection, surge protection, short circuit connection of A and B signal lines and short circuit protection with power supply (short connection without burning) • Transmission distance up to 1200 meters (tested at 9600bps) • Support baud rate 921600, much higher than 115200, higher baud rate for paired mutual transmission • Automatically identify and control the data transmission direction without any handshake signals (such as RTS, DTR, etc.). Themode conversion can be realized without jumper settings, ensuring compliance with existing communication software and interface hardware. • With TXD, RXD indicator Product parameters: 1. Power supply: USB 5V 2. Transmission distance: up to 1200 meters (9600bps) 3. Chip solution: CH340 4. Communication protocol:pure hardware device, not subject to agreement 5. Baud rate: up to 921600bps, supporting mutual transmission to support higher baud rate 6. Protection: TVS transient suppression protection, electrostatic ESD protection, surge protection, short AB signal line and short-circuit protection with power supply (short-circuit without burning) 7. Temperature range: -40 ° C - 80 ° C 8.Provide 5V power supply externally, with fuse current limit 9.Automatically determine and control the data transmission direction, without any handshake signal (such as RTS, DTR, etc.),the mode conversion can be realized without jumper setting, ensuring compliance with existing communication software and interface hardware.
