Re: [N1MM] PW-1 bus collisions
- In the listing of hardware options, I forgot to include microHAM MK2R
and MK2R+. CI-V is one of the options available from each of the two
(2) two bit ports (pins 4/5 and pins 2/3) on the accessory connector.
There are 20 different interfacing/status options for those two ports.
For example, to provide CI-V data for a PW-1 driven by Radio 1, one
would connect the tip of the PW-1 CI-V line to pins 4 & 5 of the ACC
port and connect the sleeve/shield to pin 18. "Serial Port 1" would
be set to CI-V: TX frequency", "Source" would be set to "Radio 1" and
Baud Rate/Address would be set appropriately for the PW-1.
Note: although it is possible to source data from the "focused radio"
and use a tally from the other two bit port to drive switching relays,
I don't recommend trying to "share" a PW-1 between the two radios as
that raises other issues with ALC levels, PTT switching, filtering,
bypass switching for the "other" radio, isolation, etc.
