The easy to install NEXUS MK C is a fully customized plug-and-play multiplexer for work class ROVs and is a mobilization time saver. Fitted to new ROVs or as an upgrade to existing systems it can handle data for ROV setups that require multiple cameras, sonars, attitude sensors, manipulators, cable and pipe trackers. The NEXUS MK C is the latest delivery in a series of seven multiplexers provided to MMT since 2018.

The NEXUS MK C system provides connectivity between the vessel and the ROV sensor package in one compact unit. The topside unit features an open interface that is versatile and perfect for data acquisition work aboard a wide range of vessels.

The NEXUS MK C includes a large number of sensor interfaces including Ethernet, HD video and serial channels. The 25 connectors on the subsea unit, configured to match a broad range of interfaces, allow configuration of the multiplexer for numerous tasks. Controllable power switching and health monitoring are available via an accessible software user interface.

MacArtney Underwater Technology has been supplying multiplexers to key underwater technology industries for decades. The first MacArtney NEXUS multiplexer, produced in 1999, digitized analogue signals from the depths to the surface via fiber optic cables. In the present day, the NEXUS MK C is MacArtney’s most versatile multiplexer solution, built to meet the customer’s needs.
