Maiwe MWE-820A Isolated Serial Data Converter

Product Details

Mini USB to RS-485 / RS-422 converter similar to part US485MIO, however this converter also offers RS422 communication.This surge and static protected USB to RS-485 / RS-422 converter is powered from the USB port so there is no need for an external power supply. It is designed around the high performance and very reliable CP2102 chip from Silicon Labs, so it is compatible with all verisons of Windows, Mac and Linux.This particular USB to RS-485 / USB to RS-422 adapter is suitable for most applications, including industrial, commercial and any general office computer device. It is a bi-directional, (meaning it communicates in both directions), reliable and cost-effective converter that easily lets you connect any RS-485 or RS-422 device directly to your computer's USB port, efficiently converting USB signals to half-duplex RS-485 or full-duplex RS-422 and vice versa.The RS-485 / RS-422 end is a standard 4-screw terminal header for easy connection of single wires. Automatic send data control is enabled by default so no external flow or handshake control is needed.Point to point or point to multipoint networks with up to 32 nodes can be used with this converter. The typical communication distance is up to 9800 FT (3km) at 4800bps and 6500 FT (2km) at 9600bps.Overall Features:USB port-powered converterSupports RS485 and RS4222 feet USB extension cable includedIndication lights for RX and TXUp to 32 nodes in network configurationProtected against electrostatic voltagesSpecifications:Part numberMWE820AOperating systemWindows 10, Windows 8.1 / 8 (32/64-bit), Windows 7 (32/64-bit), Vista (32/64-bit), XP 32/64, Server 2003, 2000, ME, 98Se (all WHQL compliant)Linux 2.6.x, 3.x.xMac OS X 10.4, 10.5, 10.6, 10.7 and 10.8.Windows CE 5.0, 6.0Android 4.2ProcessorSilicon Labs CP2102RS485 output power4.7VDC (between D+ and GND)RS485 / RS422 InterfaceScrew terminal blockFail-safe bias resistorsYesSignalsRS485, 2-wire half duplex: D+, D-, GNDRS422, 4-wire full duplex: TX+, TX-, RX+, RX-, GNDCompatible withModbus RTU/ASCII, BACnetBias resistorsYesUSB interfaceStandard type A maleIndication LEDsPower, Send and ReceiveBaud rate300 to 921600bpsParityNone, Odd, Even, Mark, SpaceData Bits5, 6, 7, 8Stop Bits1, 1.5, 2TX / RX buffer size640 byte transmit buffer, 576 byte receive bufferFlow ControlHardware or Xon / XoffCOM port accessible byIncluded virtual COM port driversSpecial features- Event character support - Line break transmission- Automatic Send Control
