This download is for computers that have the usual Intel or AMD chipset. It is not a set of driver files, but is an installer program that installs the driver automatically.
Please be sure to follow this sequence:-
1. Disconnect all DesignaKnit Cable Links.
2. Download and run this installer.
3. Restart Windows if requested.
4. Connect the Cable Link(s).
If DesignaKnit is not installed on this computer, then after downloading, save the file onto removable media such as a memory stick or CD. Transfer it to the computer that DesignaKnit is installed on and run it from there.
When a DesignaKnit cable link or USB converter is attached to a computer for the first time, the driver is usually installed automatically from the internet. The download available on this page is intended to help solve driver problems where the normal installation didn’t work.
However a driver was installed, the normal procedure for updating it can be found here and it should not normally need to be updated from this page.
If the Mac has the M1 or M2 ARM chipset, the automatic driver installation might not work, and it may be necessary to download this set of ARM driver files. Other Macs should be able to use the normal driver.
This driver is for the following USB links:
USB to serial converters:
This driver is also suitable for the newer type of DesignaKnit USB to Serial Converter with the FTDI chipset, but not for the older type that has the Prolific chipset. Please see
