Elecraft K3 with KIO3B USB interface

[W4FI]

I just installed the KIO3B USB interface in my K3.  How do I connect the RRC-1258 as I no longer have an RS-232 port on the radio?  I probably cant see the forest for the trees here so any help is appreciated.

Thanks

Hi

It looks like they have replaced the D-sub with a RJ45 connector in KIO3B interface. Im sure Elecraft have a adapter cable available where you get the D-sub back. I found the cable in the manual E980297

According to the K3S manual, the adapter is supplied with the K3S. This is the same RS232 port as on the K3,
just changed to an RJ45 to save space.
