I suspect they are data, voice, or video jacks. Found in a conference room for a building from the 80s-90s. It’s the same wall as the TV. There’s also other existing RJ45 Cat 5 ports.
From the 80s-90s, my guess would be some proprietary format of conferencing or intercom that has not existed for thirty years or more.
They match the style of proprietary A/V control system ports used in 1990s conference rooms, Projector control interfaces, Crestron / AMX / Extron wall plates, RS-232 or RS-485 wiring inside custom housings.
They were used to connect Projector control panels, Motorized screens, Audio/video switchers, Touch panels, Old teleconferencing gear.
This is a great answer exceeding my expectations. Thank you!
No problem, being old has to have had some benefits lol. This was my shot.
Absolutely look like custom bullshit connectors used on custom boxes from the 80s.
OP said it was in a conference room. Good catch!
Did any one else see them as two faces like 😫
They look like USB A ports to me with an unusual housing around them.
I should have specified but this was found in a conference room of an old building. It was on the same wall as the TV. It would be pretty unusual to have two USB-A ports. I’m leaning towards them being network ports since those are usually run in pairs
They really do look like USB ports though. You sure they aren't run to a box where a PC would be, and let you plug in a keyboard and mouse?
Could be meant for USB KVM
Maybe some USB ports using the old serial BUS housing?
What's the back of the plate look like?
A trigger for my OCD?
There was an old DEC network connector for daisy chain coax networks where the wall socket would break the daisy chain to insert the computer being plugged in. I can't remeber what it was called but it looked something like this.
