I installed another chassis this week. This one took a little more effort since I had to make a new ground wire for it. Similar to houses having ground wires (wires that literally are connected to the ground, buried deep) many parts of the sub are grounded to the surrounding environment (seawater). This is important to protect the electronics in case of circuit overload.
I also set up and installed the new video hub for inside the sphere. The video hub takes all of the camera inputs, and directs their output to various pilot or observer monitors. It can be a simple one input to one output, or one input can output to multiple screens. The difference with the new one is that the connections can be changed from the hub itself as well as from the computer. I was able to boot up the old hub, save the settings, connect the new hub, find out the settings can’t be transferred between two different models, type in the settings, type in the settings again because the hub went through a firmware update and didn’t save the settings, and install the hub into the mock sphere. It’s pretty tight with the spacing up at the top but hopefully there won’t be too much wire switching in the sphere.
New video hub!
