Will be able to identify the device on the picture?

Good day to all.

In my server there is such piece of iron (see photo) unmarked. From it comes the signal to RS-232. It includes ava the end of the fault pair (1 pair out of 4. the Other 3 are cropped). I would like to know what it might be? On the card is the inscription FENIX A0.11. Just Google, I couldn't help :(
This stuff connects to the server that serves the Car Orionpro. Most likely, it is connected all other devices. to the system. I need to move it to a virtual server that has no COM ports. That is, through the signal Converter. But where and how this Converter to put - it is not clear, unfortunately. For this we need to understand what kind of signal goes in two transactions of twisted pair cable into the device (they are pictured below).
On the box there is nothing. None of the inscriptions.

Good day.
Maybe two wires from the smoke detectors/temperature something in the server?
Just saw the embodiment of a super hard reset and watchdog'and.
Can any contactless reader.
Maybe even just extra food.
I think we need to determine for starters where the wires connect.
Judging by the scheme, it has a microcontroller, so rather than transformation does something else.
There the wires go to a patch panel where all ComputerAnalog through... it is clear that. I mean, from one patch panel wires lead to another, then a third. What's on the other side - one God knows. - Ulises_Bailey commented on March 19th 20 at 09:24
Measure with a multimeter, we can just extra food. - meggie.Carter commented on March 19th 20 at 09:27
