ATEM Television Studio (first gen not HD) USB not working

I have a first gen TVS that has a USB port that is not working. I do not know the IP address, therefore I can't hook up to the unit in order to control it. This TVS hasn't been used recently. I am viewing the multi-view out and the inputs are all passing video, I just have no control. Is there another way to find out the IP of the unit or is there a way to do a factory reset so it will default back to 192.168.10.240? Thanks.

You might run a network scanner like Angry Ip scanner or Advanced IP Scanner.

You can run this scanner across multiple network sectors. Be sure to configure those base ip addresses also on the machine. Otherwise the scan will fail.
