Matthias, we are aware of Sony utilizing a modified RS-422 protocol.
We're looking into supporting Sony's non-standard bit rate, but no promises there just yet.
Current suggestion would be to try utilizing a CNA1, but we understand it's not ideal.
That being said, we've successfully hooked up a Panasonic ENG via RS-422 to an RCP box.
The current Beam manual explains the options available, but it doesn't exactly spell out the steps to CCU/Camera connection.
Check out page 13/14 for the options. You can download it here.
It seems like it's a case by case for these cameras out there nowadays, never the same steps for each one.
That's why I do suggest getting in contact so our engineers can chat with you first to really dig into a workflow.
Not just trying to make a sale, but actually interested in spending some time to really investigate the ideal workflows for CCU/Camera communication so we can make any adjustments where need be.
