USB-COM422-PLUS1

The USB-COM422-PLUS1 module is a single channel USB to RS422 converter module. The USB-COM422-PLUS1 is based on the FTDI FT232R and includes level shifters to support full RS422 signalling plus Power/TXD/RXD LEDs to provide a visual indication of data traffic through the module. The module uses a standard USB-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 3Mbps. The USB-COM422-Plus1 module requires USB device drivers, which are used to make the USB-COM422-Plus1 appear as a Virtual COM Port (VCP). This allows existing serial communications software such as HyperTerminal to exchange data through the USB-COM422-Plus1 to a legacy RS422 peripheral device.
