Description: , Features: All original chips are used! All use original chips! All use original chips! Industrial protection: TVS transient suppression for protection, electrostatic ESD for protection, surge for protection, short circuit connection of A and B signal lines and short circuit for 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 Multi-system support hot swap, support win98/CE/2000/2003/2008/XP/WIN7/WIN8/WIN10/ VISTA/LINUX/for MAC OS X system, USB interface can be hot swapped Automatically identify and control the data transmission direction without any handshake signals (such as RTS, DTR, etc.). The mode conversion can be realized without jumper settings, ensuring compliance with existing communication software and interface hardware. With TXD, RXD indicator Line Converter only, other accessories demo in the picture is not included. Specifications: 1. Power supply: USB 5V 2. Transmission distance: up to 1200 meters (9600bps) 3. Chip solution: CH340 Communication protocol: pure hardware device, not subject to agreement Baud rate: up to 921600bps, supporting mutual transmission to support higher baud rate 6. Protection: TVS transient suppression for protection, electrostatic ESD for protection, surge for protection, short AB signal line and short-circuit for 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. Support system: support hot swap, support win98/CE/2000/2003/2008/XP/WIN7/WIN8/ WIN10/VISTA/LINUX/for MAC OS X system, USB interface can be hot swap 10. 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. 11.
