NATUS XLTEK EMU128FS breakout box pin-out

This very short and technical post is about a piece of equipment for recording intracranial EEG, made by XLTEK, a company now part of Natus. The piece of equipment, called “breakout box”, is part of the EMU128FS system that allows recording up to 128 channels of EEG. That breakout box is a passive relay that takes “touchproof” connectors as inputs on the front side (carrying EEG signals from the patient) and relays them to four DB37 connectors on the back side towards the recording computer (figure 1). The pin-out refers to the way each touchproof connector is relayed to each pin of the DB37 connectors (figure 2).

Figure 1. Top: the front side of the XLTEK EMU128FS breakout box shows the touchproof connector inputs. Bottom: the back side shows the four DB37 connectors.

The pin-out information is not available in the documentation to the system. I am sharing this information here because I believe that it could be useful to advance neuroscientific research. This information has not been verified or endorsed by XLTEK or NATUS in any fashion. If you own a EMU128FS system, it would take you about 10 minutes and a multi-meter to get that information for yourself (and if you do, it would be great if you could share it so that we would be able to compare).
