The cable provides a fast, simple way to connect devices with 3.3 volt digital interfaces to USB. The C232HD UART cable contains a small internal electronic circuit board, utilising the FT232H, which is encapsulated into the USB connector end of the cable. The FT232H is a single channel USB 2.0 Hi-Speed (480Mb/s) to UART IC. For full details, features and enhancement descriptions please refer to the FT232H datasheet, this is available from http://www.ftdichip.com/Support/Documents/DataSheets/ICs/DS_FT232H.pdf. The digital interface of the cable is made up of ten individual wires which are terminated with single pole connectors which can be connected next to each other on a male header. The cables digital interface logic is 3.3 volts. The USB side of the cable is USB powered and is USB 2.0 Hi-Speed compatible. The cable is 1.8m long and supports a data transfer rate up to 12 Mbaud. The C232HD UART cable requires USB drivers, available free from http://www.ftdichip.com , which are used to make the FT232H 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, is used with application software to directly access the FT232H on the cable though a DLL. This is illustrated in the Figure 1-1.

Part Number Description End Connector 10 core, UL2464 24 AWG, USB to UART cable with +3.3V C232HD-DDHSP-0 Cable details digital level signals. Maximum Single pole, output of 250mA @ 3.3VDC on VCC receptacle x 10 diameter=6.5mm length = 1800mm (see Note 1) 10 core, UL2464 24 AWG, USB to UART cable with +3.3V C232HD-EDHSP-0 digital level signals. Maximum Single pole, output of 450mA @ 5.0VDC on VCC receptacle x 10 diameter=6.5mm length = 1800mm (see Note 2) Table 1.1 C232HD UART Cable Descriptions and Part Numbers Note 1: The VCC power output signal (RED wire) is 3.3V. The source of 3.3V is the on-board regulator output, which is switched onto the power output signal. Note 2: The VCC power output signal (RED wire) is 5.0V. The source of 5.0V is the USB VBUS input, which is switched onto the power output signal. FTDI supports customised end connector designs.

This cable contains an EEPROM which contains the USB configuration descriptors for that device. When the cable is plugged into a PC or a USB reset is performed, the PC will read these descriptors. The default values stored into the internal EEPROM are defined in the following table. Parameter Value USB Vendor ID (VID) 0403h FTDI default VID (hex) USB Product UD (PID) 6014h FTDI default PID (hex) Serial Number Enabled? Notes Yes A unique serial number is generated and programmed into Serial Number See Note the EEPROM during device final test. Enabling this option will make the device pull down on the Pull down I/O Pins in USB Suspend Disabled UART interface lines when the power is shut off (PWREN# is high). Manufacturer Name FTDI Product description depends on the cable. The following lists a the Product descriptions for each different cable. Product Description See note C232HD-DDHSP-0 C232HD-EDHSP-0 Includes power to operate the FT232H plus the cable Max Bus Power Current Power Source 500mA output current.

Remote Wake Up Disabled High Current I/Os Enabled Load VCP Driver Enabled Invert TXD Disabled Signal on this pin becomes TXD# if enable. Invert RXD Disabled Signal on this pin becomes RXD# if enable. Invert RTS# Disabled Signal on this pin becomes RTS if enable. Invert CTS# Disabled Signal on this pin becomes CTS if enable. Enables the high drive level on the UART and CBUS I/O pins. Makes the device load the VCP driver interface for the device. Default Internal EEPROM Configuration The cable EEPROM in the cable can be re-programmed over USB using the utility program FT_PROG.
