The USB-RS232 adaptor cables are a family of communication devices. This model, US232R, provides a
simple method of adapting legacy serial devices with RS232 interfaces to modern USB ports.
Each US232R adapter contains a small internal electronic circuit board which utilises the FTDI FT232R,
mounted inside a rugged plastic enclosure capable of withstanding industrial temperature ranges. The
integrated electronics also include RS232 level shifters and TXD/RXD LEDs to provide a visual indication
of data traffic through the adapter.
The Cable incorporates a standard USB-A 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 1MBaud.
The US232R adapter cable requires USB device drivers, available free from FTDI, which are used to make
the US232R appear as a Virtual COM Port (VCP). This allows existing serial communications software,
such as HyperTerminal, to exchange data through the US232R to a legacy RS232 peripheral device.…more
