NKK Switches has simplified the HMI by creating solutions using SmartDisplay. These solutions facilitate ease of use, require less operator training, save space, and can be scaled to the customer’s requirements. A main benefit of these systems is their universal application and that they are not dependent on proprietary protocol or tools, but are free to be used as desired.

NKK has the ability to supply solutions with most configurations, number of switches, and communication interfaces. For system design support directly from our engineering team, please call 1-877-2-BUY-NKK or email us here.

SmartDisplay product ISC15ANP4

  • Application:
    • Control System for Remotely Operated Vehicle (ROV)
  • Story:
    • Previous control system for the ROV utilized standard pushbuttons spread across multiple control panels. In an effort to increase value and efficiency, Eclipse Group, Inc. chose the NKK SmartDisplay?? as a unique solution that could operate the multiple functions of the application in one location while providing ease-of-use for operators.
  • Solution:
    • Configurations of 4×4 and 2×8 OLED SmartDisplay combine to create an armchair mounted control system managing input from the operator at the surface and converting it into actions subsea. This unique SmartDisplay solution controls the different functions of the ROV, from operating the propulsion system to controlling the lights and video cameras. NKK provided design and programming of the OLED SmartDisplay subsystem and timely production turn-around.
