Yes you need to convert the USB to serial and then the serial to TTL
levels.  There are versions of the cable available for sale for about $20
that do both conversions in one go.  Search for FT-736 TTL.

I used a USB to serial cable like this:

Then I built a small TTL level converter in a diecast box and fed it to a
din connector.  But that was mostly because I had the connector, box and
needed components in the junk box.  So it was "free".

Note that there are cheaper USB to Serial cables that do not use the
genuine FTDI chipset and do not work as well.
