[WriteLog] Unpowered Serial Adapters

[Ric Plummer]

Bob,
In general, interfaces that use control lines for power are subject to many
peculiararities. (sp?)
If you truly want a full RS-232 interface, it will require power.
>From the Writelog help files:

WriteLog asserts RTS (pin 4) and DTR (pin 20) on the rig port unless you
have also configured the Port Setup to send CW and do rig control on the
same port, in which case the DTR/RTS lines are used to send CW.

This indicates that WL already does it's best, but if you want to use CW
keying then it goes "up & down".
and the interface won't work at this point. So you may want to check your
configuration if you can live with the limits.

73,

Ric KV1W

Guys,



I have been experimenting with several different serial rig control
adapters, my collection of radios and my collection of logging software.



Here's where I'm at and what I've found.



On my CI-V interface (which is self powered) the unit comes right up and
works with Writelog, DXBase, CT, IRC and just about any other rig control
programs.



However, when using the inexpensive DTR powered interfaces only programs
with a selection in the software to hold the DTR high and thusly power the
interface work with these units.



DXBase has a selection for this,  IRC of course does..  But if this "can
happen" with Writelog, I have yet to figure it out in a few hours of
looking.  Does anybody know a configuration "INI" parameter or whatever it
takes to tell this port to wake up and keep the box powered?



Thanks ahead of time.



Sincerely,



Bob KØDD

He's Back....
