USB-COM232-PLUS2 Datasheet

Clearance No.: FTDI# 96

1 Introduction

The USB-COM232-PLUS modules are a family of Hi-Speed communication devices. 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.

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.
