The Mystery Cable

While rooting through our attic, Ruth‘s brother Owen just found a mystery cable. It almost certainly belongs to me (virtually all of the cables in the house, especially the unusual ones, do), but this one is a mystery to me.

6-of-13-pin plug, believed to be proprietary.
End #1 of the cable is a 13-pin male serial connection with 6 connected pins, spring-loaded. It seems to be designed to screw in at one end. The screw is worn.

The more I look at it, the more I feel like I’m slowly going mad, as if the cable is some kind of beast from the Lovecraftian Cable Dimension which mortal minds were not meant to comprehend. It’s got three “ends” and is clearly some kind of signal combining (or separating) cable, but it doesn’t look like anything I’ve ever seen before (and don’t forget, I probably own it).

End #2 of the cable: a microphone, perhaps?
On the other side of the split, end #2 of the cable terminates in a fine metal mesh (perhaps concealing a microphone, small speaker, or temperature/humidity sensor). It has a “push-to-talk” style clicker switch and a “tie clip” on it.

Every time I look at it I have a new idea of what it could be. Some kind of digital dictophone or radio mic connector? Part of a telephone headset? Weather monitoring hardware? A set of converters between two strange and unusual pieces of hardware? But no matter what I come up with, something doesn’t add up? Why only 6 pins? Why the strange screw-in connector? Why the clicker switch? Why the tie clips? Why “split” the output (let alone have cables of different lengths)?

End #3: an earpiece, maybe?
End #3 looks like a fibreoptic audio terminator. Or perhaps a part of an earpiece. It, too, has a “tie clip” on (do I clip it to… my ear?)

In case it helps, I’ve made a video of it. You’ll note that I use the word “thingy” more times than might perhaps be justified, but I’ve been puzzling over this one for a while:

Can you help? Can you identify this mystery cable? Prize for the correct answer!

    I need to know!

    I’m afraid the fact that it was unscrewed probably means you’ve already taken apart/hacked/broken whatever little device monitored the cable for inputs.
