I noted one of my new mother boards has an internal serial port and I
happen to have a couple of serial connectors that mount on the back
plane. Unfortunately they don't say if it's RS232 compliant. They do
give some specs.
I've seen a number of USB to serial converters, but after using one and
wiping out my whole internal USB buss I've decided to give those a bit
of caution.
What I'd really like to do is set up the system to allow me to select
the desired antenna via keyboard using BCD output. 4 lines for 10 or
full binary for 15. OTOH BCD converters are cheap, and plentiful. A
converter, opto isolators and you are in business...and I'd not need
extra control heads for the remote antenna switches. In addition I could
program the control for the 6-back to know if any lines that would show
"in use", are really being used hence when at either location I'd not
have to be concerned if the one of the other antennas displayed it was
being used by the other station if it wasn't actively being used. IOW
if the other radio is powered down, either computer could make use of
the full system... 6-pack and two RCS-8 remote switches and one
rotator. Unfortunately I only have one amp that can be remote operated
and no auto tuners. I'd like to find some circuits and programs for those.
