Thanks Dave and the Team for the efforts in getting this happening.

I used the PD-2020 as it had not had a run for awhile, all good with fixes and camera WIP etc.
Look forward to some more updates.
Fingers crossed for some higher SR's for the purpose of testing and experimentation etc.
I'll give it a spin on the Porsdown 4 later.

The Instructions at https://wiki.batc.org.uk/Jetson_Nano ok to follow
I used a 64gb card and it all sorted itself out fine.

Thanks again
Robert

Hi Robert

Portsdown 2020 should have identical functionality to Portsdown 4 for Jetson.

My guess is that you need to re-authorise the ssh connection from the Portsdown 2020 to the Jetson. As detailed here: https://wiki.batc.org.uk/Jetson_Nano#Se ... _Portsdown

Thanks Dave
Yes many times Off/On and wait before I decided to switch over to the Portsdown 4, worked first go.

ALso different usb cables just to be sure with the PD2020

Finding the Jetson is working well with a 5v3a power pack curently

More testing
Cheers

Hi Dave,

The Jetson is still working well!

I'd like to play with the audio bitrate settings (same for the Portsdown standard), looking at the config file (Mike pointed me towards the file) it seems the audio bit rate is 20kb/s or 48kb/s. How can I alter this to experiment with different rates? I can't work out how the calculations work and how I also alter the video bit rate to suit the new audio rate and alternative FECs.

Also I found something to be aware of when using a Blackmagic ATEM Extreme:

- The Extreme has two USB-C ports. I have found it is important to use the same physical port for the Jetson every time for reliable operation
- It is possible to use both USB-C web camera outputs simultaneously i.e. one to the Jetson nano and one to my PC (for MS Teams, OBS etc.)

Justin.
