Stellate EEG Machine, would like to read the input in real-time, need to jury-rig it

Question

I don't have an electrical engineering background but a neuroscience one, so apologies in advance for my poor knowledge.

Basically I have an EEG machine (Stellate Harmonie) and I would like to be able to read the data in real time. Unfortunately it saves the EEG output as a .sig file and the app itself is clunky and does not conduce itself to doing so. I am working with software engineers that code in python that are ready to work on it but can't until we can figure out a way to read the output of the machine in real-time. Any method to be able to figure this out would be greatly appreciated!

Edit: looking for a manual, but found this meanwhile, the image of the setup is here: http://userfile.alephnetwork.com/files/b2gmarekt_vendor/Stellate%20Harmonie%20%20E%20.pdf

Welcome to EE.SE. You haven't provided a link to the machine's user manual or any clue as to what interfaces are available on the EEG. — Transistor, Aug 10 '18 at 19:44
Hey Eugene: on page 8 of the document there's an image of the whole set up of the machine: http://userfile.alephnetwork.com/files/b2gmarekt_vendor/Stellate%20Harmonie%20%20E%20.pdf Does this help? @Transistor: I'm currently trying to find the manual, but I have linked what I could find — user195672, Aug 10 '18 at 20:13
Python is not a very fast/efficient language. You might need some C programmers if you need real-time processing. — Oldfart, Aug 11 '18 at 06:49

You may not be able to get the processed results in analog form but the inputs seem to interface between a junction box the Harmonie-E box. slow download Quick REf Guide

(If you are trying read from program memory in real-time you need a lot more insight) Why not deal with the factory support?

• Compressed spectral arrays for up to 128 channels without interrupting real-time recording
• Spectra and band activity for up to eight user-defined bands
• Coherence and phase spectra to measure relationships between two channels over time
• Spectral activity map. Display up to eight topographical representations simultaneously
• Long-term trend displays of band activity, ten plots at a time

I believe the company has since gone bankrupt. And so you recommend to get the input directly from the junction box? – user195672 Aug 13 '18 at 15:09
That's where to look for real-time inputs – Tony Stewart EE75 Aug 13 '18 at 16:08
How would you get the inputs from it or do we need to find an EE or Hardware Engineer? – user195672 Aug 13 '18 at 16:14
I don't know how it looks. – Tony Stewart EE75 Aug 13 '18 at 17:34
What would you need from me to be able to answer? I'm quite out of my depth, honestly – user195672 Aug 15 '18 at 16:17
You need to find an analog expert to examine if the interface signals give you what you need. You won’t get real-time signal processing of channels , I expect just the analog signals amplified. – Tony Stewart EE75 Aug 15 '18 at 16:29
What do you mean? I thought the signal would be in parallel and digital? Isn't that what the junction box does? Convert it from analog to digital? – user195672 Aug 16 '18 at 17:03
If you say so, that’s more than I expected – Tony Stewart EE75 Aug 16 '18 at 17:30
