Msposd to OpenIPC

Hi!

I am tring to realize a project with px4 flight controller and openipc camera.
I would like to see some osd of course.

The status of the msposd is the following:
nsh> msp_osd status
INFO [msp_osd] Running on /dev/ttyS3
INFO [msp_osd] initialized: 1
INFO [msp_osd] initialization issues: 0
INFO [msp_osd] scroll rate: 125
INFO [msp_osd] successful sends: 380718
INFO [msp_osd] unsuccessful sends: 0
INFO [msp_osd] Current message:
HOL|DSRM|N
INFO [msp_osd] No VTX Configuration available, can’t do channel switching

But I recieve no data on the other side:

There are random fonts on the openipc video image, but no osd.

Can you help me?

Thank you,
