This model, USB- COM232-PLUS2, provides a simple method of adapting two legacy RS232 serial devices to a modern USB port. This is accomplished by incorporating the industry standard FTDI FT2232H USB2.0 Hi-Speed serial bridge chip. The integrated electronics of the USB-COM232-PLUS2 utilise the FTDI FT2232H plus two RS232 level shifters and TXD/RXD LEDs to provide a visual indication of data traffic through the module. Figure 1.1 USB-COM232-PLUS2 The module uses a standard USB-miniB device connector for connection to an upstream host or hub port. RS232-level signals, including modem handshake signals, are available on an industry-standard DE-9P connector. The maximum RS232-level data rate is 1Mbps. The USB-COM232-PLUS2 module requires USB device drivers, available free from www.ftdichip.com, which are used to make the USB-COM232-PLUS2 appear as two Virtual COM Port (VCP). This allows existing serial communications software, such as HyperTerminal, to exchange data through the USB- COM232-PLUS2 to a legacy RS232 peripheral device.
