The power supply and signal are fully isolated, with stronger anti-interference ability and safer use! USB To RS485 converter allows PC users to connect their RS-485 devices to systems that use USB interface. By attaching the converter to a PC, it will no longer be necessary to open the chassis or turn off the PC to install the hub. With the converter, the user instantly gets one extra high-speed RS-485 ports. In addition, 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, POS system and industrial control devices. Power supply: USB 5V Transmission distance: up to 1200 meters (9600bps) Chip solution: CH340E Communication protocol: pure hardware device, not subject to agreement Baud rate: up to 256000bps, supporting mutual transmission to support higher baud rate The power supply and signal are completely isolated, and the anti-interference ability is stronger 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) Temperature range: -40 ° C - 80 ° C Support system: support hot swap, support for win98 for CE for 2000 for 2003 for 2008 for XP for WIN7 for WIN8 for WIN10 for VISTA for 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.) without jumper settings to achieve mode conversion, to ensure compliance with the existing communication software and interface hardware. Different batches, the color of the PCB board inside the converter is random, don't accept the specified color; computer display Different, the color of
