For any serial cable used in a ham shack, including this one, you should
use twisted pair cable for each circuit to minimize RFI
Ken,
For those purchasing a used K2, this seems to be a common problem, the
seller may not provide all the cables and accessories that originally
came with the K2 and its options. That includes a 2.1mm coaxial power
plug, a 3.5mm stereo plug that may be used for the key jack, the

2. Does any manufacture K2 RS232 cables?
Sure ... You do! The K2 is a 'melt-solder' kit. The K2 manual spells
out how to make the correct cable.
The K3 uses 'normal' 9pin serial cables. The K2's cable included
Elecraft's aux-bus info for the external ATU. The K3 mounts the ATU
internally. If a
The computer cable for the K2 requires only three wires connecting
pins 2, 3 and 5 on each end. The other pins must not be connected
since the KIO2 signals on these pins are not RS-232 capable.
Connecting them to an RS-232 connector will cause damage in the K2.
The K3 can use a standard
Ken:
The K3 uses a straight-through RS-232 cable with DB-9 connectors on either
end. The most common of these cables has all 9 pins connected, M-F, no
crossovers. The cable is described in the K3 Utility Help.
Not all of these pins are required for normal operation, but it doesn't hurt
to have
Thanks Dick and Jack...
I just wanted to be certain I was not missing something IRT to the K3.
I saw the info in the KIO2 manual on building the cable, but thought I had
seen something about pre-made cables (which would undoubtedly be MUCH
prettier than anything I can turn out!). As I bought the

Jim Brown K9YC has posted much good advice on this subject. Take a look
at his website information at

Pay particular attention to his comments about using twisted pair (CAT5)
for RS-232

hehe.. I expect we'll see quite a bit of flogging over the next few months. :-
I found the manual to be very well done. It is well written, coherent and
very easy to understand. Everything makes sense. Kudos to those that worked on
it.
I can't believe people are whining about the
