The SENSYS Top Side Unit (TSU) allows a straight connection from the submersible MX3D UW data acquisition units, that are usually connected to a ROV MUX, to read out the MX3D UW data to a PC. With an IP65 rated housing and waterproof connectors, the TSU can be placed on deck or in the field at nearly any condition. Furthermore, it converts the 230VAC to the required 24V of the MX3D UW.
