APPENDIX - GKD USB DRIVER INSTALLATION
Introduction
The GKD USB to CAN Converter includes an FTDI USB interface chip and a special Windows
driver is needed to allow the GKD Series 1-L PC software to use a USB port to talk to the
Series 1-L Display Unit. This note details how the driver software can be installed.
Windows version
The version of USB Driver required for a particular PC may depend on which version of
Windows operating system is installed on that PC. Many modern computers with Internet
access may automatically search for a suitable driver on the internet and install it for you.
Older PCs, or where there is no Internet access, may require the drivers to be available on
the PC already and a Windows Driver Installation Wizard told where to look for the driver.
Note that ONLY Windows XP, Vista & Windows 7 are supported.
Plug in USB to CAN Converter and install drivers
Plug the USB to CAN converter into a USB port and a Found New Hardware report is seen
indicating a USB Serial port. A Found New Hardware Wizard appears, as shown below:
If the PC has Internet Access you may be able to set the “Yes, this time only” button and
click Next for the PC to find and install the right driver. Advice may also be obtained from
the FTDI website on how to obtain a suitable VCP driver for their USB chip.
If there is no Internet Access, or a driver can’t be found then at this stage click the “No, not
this time” button and Next. A new screen appears asking for the location of the driver file.
If Windows can’t find a driver load driver interface files onto PC
If windows can’t find a driver, or there is no internet access, GKD supplies driver files on a
CD. Create a new “USB Driver” folder on the PC, typically entitled C:\USB Drivers, and load
GKD’s driver folder from the CD into that folder. The folder is typically called “USB FTDI
Drivers”.
In the “USB FTDI Drivers” folder there should be two .pdf files that give instructions for
Windows XP and Windows 7 Computers Installations. Typically run the setup file:
CDM 20814_ Setup.exe
to run the installation file & load drivers.
The USB to CAN Converter should now work correctly with the GKD Series 1-L PC software.
