USB-COM422-PLUS-4

FTDI  USB-COM422-PLUS-4  开发模块, USB-RS422, 4通信口

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.
