RS-232 interface question

Hi folks.
I'm planning on building the 100W kit for my K2, and the 100W ATU, both together in a remote enclosure. Do I, or do I not, need the KIO2 RS-232 Interface kit, given that both the amp and the ATU are remote? Offline replies OK, as this is probably an old question!!

I have the setup that way and yes you will need the kio2 to make it all easy
to hook up it can be done with out it but you have to make a special cable
so it was easier to put the kio2 in and have it for when you go qrp and have
it for when you go qro.

Ted,

When you remote the KPA100, you must provide a path for the internal K2
signals that are required for its operation, and the KIO2 does bring out
those signals - the KIO2 is more than an RS-232 interface and that is the
reason there are cautions that a standard RS-232 cable MUST NOT be connected
to the K2 or KPA100 (even though the connector is the same - bad things will
happen to your K2 or KPA100 if you should accidently connect it with a
RS-232 cable.

There are alternatives to installing the KIO2 (see
http://www.qslnet.de/member/la3za/K2/mod.html for details), but if you want
a connection to the computer, the KIO2 is your only alternative.

When you remote the KPA100, any connection to a computer must be directly
from the base K2 - the RS-232 signals in the KPA100 will not function with
the remote KPA100 configuration.

73,
Don W3FPR
