Evening All,

Found my self working in an old royal bank of Scotland today and was disconnecting and removing some items and I came across a load of these. I assume they were old fashion data-ish points but anyone shed some light? 4580B39E-BD2D-46C1-B09A-DE5CAE0F71FC.jpeg

The round ones are XLR sockets, commonly used for data (Disco lights still use them)
The white oblong ones I believe were actually designed so that you could have two sockets side by side in a single outlet box.
So as they were in a bank they must have been to plug in a data transmitting device, but using the oblong sockets so you could not plug anything other than the "data transmission device" in. They were made by "britmac"

I thought they looked like XLR but didn’t know that it could have been used for data and yes they were Britmac boxes. I knew somebody in this forum would have know……..does anybody want any? 😂😂

3-pin XLR's are also used for professional audio, a couple of quid for used ones on auction sites.

Yes, and it can be a right nuisance keeping XLR audio cables and XLR lighting cables separate in a band environment because the cable types are very different. XLR cables for DMX lighting control uses twisted pairs for RS-485 serial data.

The area would have been for communications. The XLR for audio send (mic) and return for headphones. The rest has already been explained and is for power.
