DAM-3232N
DAM-3232N is a universal USB/RS-485/422 converter without external power supply, compatible with USB, RS-422 and RS-485 standards. It can convert single-ended USB signals into balanced differential RS-422 or RS -485 signal, provide surge protection power per line, surge voltage generated on the line due to various reasons, and the extremely small inter-pole capacitance, and ensure the high-speed transmission of the RS-485/RS-422 interface. The RS-422 and RS-485 ends of DAM-3232N are connected through DAM-CONVERT and DB9 male connectors. The converter has zero-delay automatic transceiver conversion function, and the unique I/O circuit automatically controls the data flow direction. Without any handshake signals (such as RTS, DTR, etc.) and jumper settings, it can achieve full duplex (RS-422 ) and half-duplex (RS-485) mode conversion, just plug and play, so as to fit all existing communication software and interface hardware. DAM-3232N interface converter can provide reliable connection for point-to-point, point-to-multipoint communication, each point-to-multipoint converter can connect 32 RS-422 or RS-485 interface devices. The data communication rate is 110bps ～750Ksps, and the supported communication methods are USB to RS-422, USB to RS-485 conversion.
