Previously, these drivers were mutually exclusive and could not be installed at thesame time. The new Windows combined driver model (CDM) which may be installed on Windows 2000,XP, VISTA or Windows 7 allows applications to access FTDI devices through either the D2XX DLL or aCOM port without having to change driver type. However, it should be noted that an application can onlycommunicate through one of these interfaces at a time and cannot send commands to the D2XX DLL andthe associated COM port at the same time.The CDM driver comes in two parts. The first part is the bus layer that provides D2XX style functionalityand is always installed. The second part is the serial COM port layer and the CDM driver will determinewhether a COM port should be exposed by reading the EEPROM of FT232R, FT245R, FT2232D, FT232H,FT2232H, FT4232H and FT-X devices. In the case of FT232BM, FT245BM, devices, the CDM driver willdefault to always installing a COM port.This behavior can be changed and EEPROM settings ignored by changing the driver INF files as detailed inFTDIApplication NoteAN-107 Advanced Driver Options. Please note that modifying the INF files of aMicrosoft WHQL certified driver will invalidate the Windows certification.The driver is downloadable from the FTDI website found at the following links:VCP:D2XX:Copyright © 2015 Future Technology Devices International Limited 3Document Reference No.: FT_000160FTDI Drivers Installation guide for Windows 7Version 1.1Clearance No.: FTDI# 1203Installing CDM DriversTo install CDM drivers for an FTDI device under Windows 7, follow the instructions below:Connect the device to a spare USB port on your PC.If there is an available Internet connection, Windows 7 will silently connect to the Windows Updatewebsite and install any suitable driver it finds for the device.If the automatic installation takes place there is no need to continue with the procedureoutlined below.If no suitable driver is automatically found then the following procedure should be followed.Press the Windows start button to bring up the start menu and select “Control Panel”.Copyright © 2015 Future Technology Devices International Limited 4 [ Pobierz całość w formacie PDF ] |
