USB I/O 24 R Datasheet
Driver Installation
Your first choice when using the USBIO24 is whether you want to use the Virtual COM Port driver
or the Direct DLL driver.
For programming simplicity the best driver is the Virtual COM Port and when installed the
USBIO24 will appear in the System Properties / Device Manager as an USB Serial Port (COMn) as
follows.
The COM port number will vary depending on the number of existing COM ports on your
computer and the number of USBIO24 s or USBMODs connected to your system.
To install the Virtual Com Port drivers, download the driver from our website or the ftdichip.com
website and unzip the files to a local directory. Connect the USBIO24 and windows will
automatically ask for the driver, select to specify a location and browse to the directory where you
have unzipped the files. (Use of the Non Plug & Play driver for the USBIO24 is recommended to
avoid a delay on connecting the USBIO24 )
Once the Virtual COM Port is installed it can be programmed exactly as a regular serial COM port
using the MSComm control from within VB or API calls from C or other languages. Set the COM
port to the same number as appears in the Device Manager, the baud rate, stop bits, parity etc are
not used as the device always runs at full speed.
The Direct DLL driver is installed in a similar manner but using the alternative download from the
website.
Programming the Direct DLL driver is by call to the DLL Library functions.
Please download the Direct DLL programmers guide from the FTDI website.
NOTE: Only one driver for the device can be installed at any one time.
