[Elecraft] K2 with MacOS Classic

[Dan Barker]

Yes, and then you get to buy a bunch of parts for your KIO2<g>!

DO NOT CONNECT RS-232 to your KIO2 without opening all unused (by RS-232)
pins. ONly Sig Ground, TX and RX go from computer to K2. All other lines on
the KIO2 are not RS-232 and can't tolerate the +- 15V the computer will
supply.

No I don't, but probably the easiest way to do this would be to to find
a
Mac specific Modem Cable (Ebay for $4 US).  It will have the correct DIN
connector for the Classic Mac serial port and a DB-25 connector at the
other end. My guess is that you would just need a DB-25 to DB-9 adaptor
to connect the cable up to the K2 (it looks like the KIO2 has a DB-9
on it).  The adaptor, I believe, should be straight through as I am
assuming
that the computer would view the K2 as being DCE, just like a modem.
