CAT control via Omnirig (Xiegu G90)

Hi All,
Apologies, I originally posed this in the v1 support section by mistake but I am actually using v2. Perhaps a moderator could delete my OP?
New ham here looking for the best logging software!
I have a Xiegu G90 which is supported natively by Flrig and uses the Icom-7100 settings with baud rate of 19200 in Omnirig.
Flrig works flawlessly but I am having problems getting Omnirig to work with Log4OM. Both the test clients installed with Omnirig work fine, but I cannot for the life of me get Log4OM to interface with Omnirig for CAT control. I have looked at lots of posts on here and a few people seem to have the same problem but I have not been able to find a solution. I have also watched Terry’s video tutorials which were great.
It’s a pity Log4OM doesn’t work with Flrig out of the box, and Hamlib looks confusing!
Any help would be much appreciated.
Regards,
Simon (M7WWX)

CAT via Omnirig and Flrig (to control Fldigi) the same time does not work.
I do it that way:
To work with Fldigi
Rig --> Cat --> Flrig --> Fldigi
Logging:
No cat in Log4OM. But I sent the logged contact (with the correct QRG etc.) via UDP from Fldigi to Log4OM.
Configuration --> ADIF Functions: Enable ADIF Monitor checked and ADIF files, add the Fldigi logbook.
Applications --> Fldigi --> set the UDP port there.

Many thanks for the reply. I realise you can’t use Flrig and Omnirig as the same time, as the COM port can only be used by one program.
I had the latest version of Log4OM and Omnirig installed, so this evening I uninstalled everything and reinstalled, opting to install the version of Omnirig bundled with the Log4OM installation.
It’s obviously an older version of Omnirig but hey presto, I have CAT control! Now I need to work out how to interface Log4OM with WSJT-X…

Guess you had been using the Swiss version of Omnirig which does not work with Log4OM

By the way Simon,
my G90 runs with Omnirig with the following settings:

Thanks Juergen,
I’ve seen you post these settings before.
In fact both these seem to work equally well.
Do you know what the differences mean?

Think RTS & DTR are only needed if a software switches PTT. If not there will be no difference between High or Low. That's what I think about it.

I realise that Terry. Was just highlighting that on the 2-tab version, Omnirig works with 1 or 2 stop bits selected, and RTS and DTR set to low or high. I wondered what effect these settings have.
Shouldn’t have included the Swiss screenshot, but the settings highlighted also work on the older version.
Regards,
Simon

RTS and DTR were from the old times mostly where you used a serial com port on your PC. With USB in most cases these settings are obsolete.
