描述:
The USB-COM422-PLUS4 module is a single USB interface to four independent RS422 ports, communication device. The integrated electronics of the USB-COM422-PLUS4 utilise the FTDI FT4232H (USB 2.0 Hi-Speed device) and includes RS422 level shifters plus Power/TXD/RXD LEDs to provide a visual indication of data traffic through the module. The module uses a standard USB Mini B device connector for connection to an upstream host or hub port. RS422-level signals, including modem handshake signals, are available on an industry-standard DE-9P connector. The maximum RS422-level data rate is 10Mbps. The USB-COM422-PLUS4 module requires USB device drivers, which are used to make the USB-COM422-PLUS4 appear as four Virtual COM Ports (VCP). This allows existing serial communications software such as HyperTerminal to exchange data through the USB-COM422-PLUS4 to a legacy RS422 peripheral device. . Adds quad RS-422 serial ports by connecting to a USB 2.0 Hi-Speed interface. . Easy plug & play installation and RS-422 device connection . Works with USB 1.1 & 2.0 Host and Hub ports .
