[Trlog] RE: ICOM Control

[Bob Lanning]

I bought off of eBay a cable with the converter built in to the head of
a DB9 connector.  Power was supplied via the serial port.  Of course I
had moved the keying over to the parallel port.  Works great.

For those who may be tracking this thread:
 
If you are planning to use the voltages from the COM port that is
controlling the RADIO to provide voltage for a CI-V type controller this
may
be of interest to you.
 
W9RE sent me a note stating he was getting voltage from pin 20 (DTR) and
his
serial port powered controller worked. Pin 20 is used for keying CW in
my
setup (an accepted TR setting).
 
Just to see what would happen I changed KEYER CONTROL to a parallel port
and
started TR. The RTS and DTR lines were active (high) whereas they had
NOT
been active in the configuration that had KEYER CONTROL set to the
serial
port that controlled the radio. This change provided voltage for the
serial
controller I am using and it began to function --- not entirely
perfectly,
but still it was obvious that the frequency of the radio was being read
and
sometimes I could change bands using ALT-V or ALT-B. There may be some
other
timing parameters I need to change or it may be that the fact I am
running
TR in a Win98 DOS window may be affecting the timing of bytes to and
from
the COM port. I will report on this later after further testing.
