[Elecraft] how to build interface cable between K3 and XV144

[Ron D'Eau Claire]

Fb Jonny. I believe the same cable works. I use my transverter cable as =
an
RS-232 "extension cord" between my computer RS232 port and the K3.=20

Yes, the K2 "AUX" connector is not a true RS232 port. But the three =
wires
used in the cable are compatible with either the AUX port or an RS232 =
port.
They have the three basic lines needed  for most communications.=20

The real danger is in hooking a full RS232 cable to the K2 AUX port. =
That
often results in damaging voltages being applied to the K2 AUX port =
because,
other than the three lines + ground shown in the transverter cable, some =
of
the other connections are not the same as used in normal RS232 busses.=20

Hello Ron,

Thanks for your reply.

Yes, I did read p.9 of the XV144 operation manual.  However, it only =
shows
the interface cable from XV144 to KI02 of K2 and NOT K3.

>From reading of the K3 manual, the RS232 socket has a different usage=20
>in K3 and the wiring is not similar to KI02. Is my understanding=20
>correct?  If yes, where can I find similar diagram as that in p.9 of=20
>the XV144 manual for building the interface cable between XV144 and K3.

cheers,
