Features: 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. 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. 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. 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. Lightweight and Convenient - Small size, light weight, simple and practical. Specification: Material: ABS Color: Black, White (optional) Size: approx. 11 * 7 * 1cm / 4.33 * 2.76 * 0.39inch The RS-485/RS-422 terminals of this series of interface converters support the following four networking modes: 1. Point-to-point four-wire full duplex (RS-422) 2. Point-to-multipoint four-wire full-duplex (RS-422) 3. Point-to-point two-wire half-duplex (RS-485) 4. Point-to-multipoint two-wire half-duplex (RS-485) When the converter is used as full-duplex or half-duplex wiring, in order to prevent signal reflection and interference, a matching resistor (parameter 120 ohm 1/4W) is required at the end of the line.
