The cables provide a fast, simple way to connect devices with a RS232 level serial UART interface to USB. Each USB-RS232 cable contains a small internal electronic circuit board, utilising the FT232R, which is encapsulated into the USB connector end of the cable. The FT232R datasheet, DS_FT232R, is available at http://www.ftdichip.com. The integrated electronics also include the RS232 level shifter plus Tx and Rx LEDs which give a visual indication of traffic on the cable (if transparent USB connector specified). The other end of the cable is bare, tinned wire ended connections by default, but can be customised using different connectors to support various applications. Cables are FCC, CE, RoHS compliant. The USB side of the cable is USB powered and USB 2.0 full speed compatible. Each cable is 1.8m long and supports a data transfer rate up to 1 Mbaud. Each cable supports the FTDIChip-ID™, with a unique USB serial number programmed into the FT232R. This feature can be used to create a security or password protected file transfer access using the cable. Further information and examples on this feature are available at http://www.ftdichip.com under FTDIChip-ID Projects. The USB-RS232 cables require USB drivers, available free from http://www.ftdichip.com, which are used to make the FT232R in the cable appear as a virtual COM port (VCP). This then allows the user to communicate with the USB interface via a standard PC serial emulation port (for example TTY). Another FTDI USB driver, the D2XX driver, can also be used with application software to directly access the FT232R on the cable though a DLL. This is illustrated in the Figure 1.1 Various Connector Options VCP TTY Wire Ended USB_RS232 Customised connectors USB Virtual COM Port Various Connector Options Wire Ended D2XX DLL TTY USB Customised connectors Software application access to USB via D2XX Figure 1.1 Using the USB-RS232 Cable Copyright © 2010 Future Technology Devices International Limited 1 Document Reference No.: FT_000077 USB TO RS232 SERIAL CONVERTER RANGE OF CABLES Datasheet Version 1.3 Clearance No.: FTDI# 51 2 Cable Part Numbers The following Table 2.1 gives details of the available USB-RS232 cables.

This section summarises the key features of the FT232RQ which apply to the USB-RS232 USB to serial RS232 converter cables. For further details, and a full features and enhancements description consult the FT232R datasheet.This is available from www.ftdichip.com. Internal EEPROM. The internal EEPROM in each cable is used to store USB Vendor ID (VID), Product ID (PID), device serial number, product description string and various other USB configuration descriptors. Each cable is supplied with the internal EEPROM pre-programmed as described in Appendix A - Cable EEPROM Configuration. The internal EEPROM descriptors can be programmed in circuit, over USB without any additional voltage requirement. It can be programmed using the FTDI utility software called MPROG, which can be downloaded from FTDI Utilities on the FTDI website (www.ftdichip.com). Additionally, there is a user area of the internal EEPROM available to system designers to allow storing of data (note that this is not modified by MPROG). Lower Operating and Suspend Current. The FT232R has a low 15mA operating supply current and a very low USB suspend current of approximately 70μA. (Note that during suspend mode, the current drawn by any customised cable application which uses the USB supply, should not exceed 2.5mA to remain USB compliant) Low USB Bandwidth Consumption. The USB interface of the FT232R, and therefore the USB-RS232 cables has been designed to use as little as possible of the total USB bandwidth available from the USB host controller. UART Pin Signal Inversion. The sense of each of the UART signals can be individually inverted by configuring options in the internal EEPROM. For example CTS# (active low) can be changed to CTS (active high), or TXD can be changed to TXD#. FTDIChip-ID™. The FT232R includes the new FTDIChip-ID™ security dongle feature. This FTDIChip-ID™ feature allows a unique number to be burnt into each cable during manufacture. This number cannot be reprogrammed. This number is only readable over USB can be used to form the basis of a security dongle which can be used to protect any customer application software being copied. This allows the possibility of using the USB-RS232 cables as a dongle for software licensing. Further to this, a renewable license scheme can be implemented based on the FTDIChip-ID™ number when encrypted with other information. This encrypted number can be stored in the user area of the FT232R internal EEPROM, and can be decrypted, then compared with the protected FTDIChip-ID™ to verify that a license is valid. Web based applications can be used to maintain product licensing this way. An application note, AN232R-02, available from FTDI website (www.ftdichip.com) describes this feature. Improved EMI Performance. The USB-RS232 cables are FCC and CE certified. Extended Operating Temperature Range - The USB-RS232 cables are capable of operating over an extended temperature range of -40º to +85º C thus allowing them to be used in automotive or industrial applications.
