Introduction
1.1
Functional Description
The USB-COM-Plus modules are a family of communication devices. This model, USB-COM232-Plus1,
provides a simple method of adapting legacy serial devices with RS232 interfaces to modern USB ports.
This is accomplished by incorporating the industry standard FTDI FT232R USB-Serial bridge chip.
The integrated electronics of the USB-COM232-PLUS1 utilise the FTDI FT232R and includes RS232 level
shifters plus 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.
RS232-level signals, including modem handshake signals, are available on an industry-standard DE-9P
connector. The maximum RS232-level data rate is 1Mbps.
Pin 9 of the DE-9P connector can be configured to output (+5V) with a configuration utility available free
from www.ftdichip.com.
The USB-COM232-Plus1 module requires USB device drivers, available free from www.ftdichip.com, which
are used to make the USB-COM232-Plus1 appear as a Virtual COM Port (VCP). This allows existing serial
communications software, such as HyperTerminal, to exchange data through the USB-COM232-Plus1 to a
legacy RS232 peripheral device.
