[Elecraft] K4: Do I need with a K4 digi keyer like with my K3 ?

[DJ8EW]

I'm waiting for my new K4D. Now I still use a K3 with an old microham
'DIGI KEYER' as interface to my PC for contest (Wintest) and logging in
all modes including RTTY and digi modes and a cw-skimmer.
Did I understand the K4D information correct that all these features can
be done with the K4D and my windows10 PC without the DIGI KEYER hardware?
