Television HD update question

I have run into an issue where, after updating our presentation computer's (Mac Mini) OS (over a year out of date), video is now not being sent to our ATEM Television HD switcher. Just a black screen.
After replicating with other cables and another (updated) machine, I speculated this was due to an out-of-date firmware on the switcher.
However, after updating the Control and ATEM Setup software, I have not been prompted to update the switcher.

https://i.imgur.com/ySI4K7P.png <--- current software installed on the switcher, per ATEM Setup. Version 8.1.1. As far as I can tell, this is the version it was shipped with.
The manual says updates will be prompted by the software. I did not receive such a prompt even with multiple reboots, restarts etc. And there is no way to force a check. So:
1) What is the most current software version for the Television HD switcher? Am I out of date or not?
2) If I am out of date, how do I go about manually updating?
- ATEM Setup does detect the device just fine, and I am connected via USB.
- The Mac does detect the BMD switcher as a display, and has been properly set.
I have already contacted support and hopefully will be hearing back from them soon, but any help is appreciated.
