• The power supply and signal are fully isolated, with stronger anti-interference ability and use
• USB to RS485/RS232 converter allows PC users to connect their RS-485//RS-232 devices
• By attaching the converter to a PC, it will not be necessary to open the chassis or turn off the PC to install the hub
• Since the power is derived from the USB port, there are not any cumbersome power adapters. This makes the converter especially suitable for PLCs, printers, systems and industrial
• Industrial-grade protection: TVS transient suppression protection, electrostatic ESD protection, surge protection, AB signal line short connection and short connection protection with the power supply (short connection does not burn)
• Multi-system support hot-plugging, support for Win98/CE/2000/2003/2008/XP/WIN7/WIN8/WIN10/VISTA/LINUX/MAC OS X system, USB interface can be hot-plugging
• Automatically identify and control the direction of data transmission without any handshake signals (e.g. RTS, DTR, etc.) No jumper settings can be realized without mode switching to ensure compliance with existing communication software and interface hardware
