[Elecraft] RS-232 interface question

[W3FPR - Don Wilhelm]

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
