Features:
- All original chips are used! All use original chips! All use original chips!
- 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
- Multi-system support hot swap, support win98/CE/2000/2003/2008/XP/WIN7/WIN8/WIN10/VISTA/LINUX/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.
