<p>Features:</p> <p>USB power supply, no need for external power supply: Compatible with USB1.0\/1.1\/2.0, RS-422, RS-485 standard, can convert USB signal and protocol frame into balanced differential RS-422 or RS-485 signal and UART protocol. The frame can realize the bridging of the star USB network to the RS-422\/RS-485 network, which is equivalent to a bridge device. This series of products provides surge protection per line and 600W lightning protection. </p> <p>Adopts TVS and thermistor dual lightning protection and surge protection technology: It can effectively resist lightning strikes and surge voltage generated on the line for various reasons, and maintain a very small interelectrode capacitance, ensuring high-speed transmission of the RS-422\/RS-485 interface. </p> <p>The converter with internal no delay automatic transmission and reception conversion: The unique I\/O circuit automatically controls the data flow direction without any handshake signal (such as RTS, DTR, etc.), and does not need jumper setting to achieve full duplex ( RS-422), half-duplex (RS-485) mode conversion, plug and play ensures that it is suitable for all existing communication software and interface hardware. </p> <p>Support for point-to-point, point-to-multipoint communication: Point-to-multipoint converters can allow connection of 32 RS-422 or RS-485 interface devices, data communication rate 300-128000bps, with power indicator lights and data flow indicators to indicate fault conditions. Supported communication methods are USB to RS-422, USB to RS-485 conversion. </p> <p>Lightweight and Convenient - Small size, light weight, simple and practical. </p> <p>Specification:</p> <p>Material: ABS</p> <p>Color: Black, White (optional)</p> <p>Size: approx. 11 * 7 * 1cm \/ 4.33 * 2.76 * 0.39inch</p> <p>The RS-485\/RS-422 terminals of this series of interface converters support the following four networking modes:</p> <p>1.
