Specifications: 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 Colour: blue Material: PCB+plastic+metal Size: 70x27x13mm 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. Note: Different batches, the color of the PCB board inside the converter is random, don't accept the specified color; the computer display is different, the converter color may vary. Package Contents: 2 * USB To RS485 RS232 Converter

Package included: 2pcs USB to RS485 RS232 Converter. 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. The power supply and signal are fully isolated, with stronger anti-interference ability and safer use!. The power supply and signal are fully isolated, with stronger anti-interference ability and safer use!. USB To RS485/422 converter allows PC users to connect their RS-485/422 devices to systems that use USB interface.
