Hello,
I am currently trying to find a way to measure DC voltage across a device(s) to read via a serial RJ-45.
I use an opengear OM2224 serial monitor to remotely serial connect into some devices at various sites.
Edit: My relay racks are equipped with a -48VDC configuration but when measured range up to roughly -52VDC.
I am open to any ideas, please share your thoughts with me.

What I'm trying to do:
Somehow read a voltage of a device (i.e. router, switch, etc.) by using a serial RJ-45 connection. I've seen things like DATAQ, but they require an OS to export the measured data. I'm capable of doing a Serial RJ-45 connection or a Serial USB connection, per the OM2224 specs.Things I have considered:
- using an Arduino or ESP32, since some are built with an on-board analog-to-digital convertor (ADC).
- DATAQ (but requires an OS to export data or a USB stick to save to, unfortunately I cannot remotely access it.)
Skillset:
I do have a good formality with:- ESP32s
- Coding (any language)
- FPGAs
- Circuits
- Power
I am open to any ideas, please share your thoughts with me.
