[Elecraft] KPA100 - RS232 difficulties

Sun Jan 12 15:34:01 2003

Make sure the interface cable is wire exactly as shown in the diagram.
Haven't built the KPA100, but know the diagram is in the KIO2 manual, =
which
can be downloaded.  I got the exact same problem when I tried a three =
wire
cable that I had use on other rigs.  The K2 remote looks to see if pins =
7 &
8 are hooked together, if not, then it gives you the error message.  May
want to check the PC end of the cable with an ohm-meter to be sure.

Hello fellow Elecrafters

Just finished up the KPA 100 - the PA works fb.

However, I cannot get the RS232 port to work.

I have checked the computer cable three times and resoldered the pins of =
U4.

I can turn the port on and off, using the menu command

Using Hyperterminal, I can get the K2 to send the frequency to the =
computer
ok., but I cannot send the  command (SW01;) to the K2 to get it change
bands.

When I run K2 remote and select the COM port, K2 Remote comes back with =
an
error message to check the RS 232 connection or make sure the K2 is =
powered
up.

Anyone have any suggestions or ideas on things to check?
