Breaking through the architecture of HMI hardware and software, we freed HMI from its traditional combination with LCD panel and touch screen, and perfectly integrated HMI’s visual control into iPad with the powerful EasyBuilder project editor software. Not only do we inherit the advantage of traditional HMI and the motto of “Make Things Easy,” we also encourage infinite innovation in HMI technology and lead HMI into the cloud. FEATURE ● Multiple iPad Clients A cMT-SVR can be operated by three iPads simultaneously, and by Account Management in EasyBuilder, user accounts and access privileges can be managed properly. ● One iPad, Multiple cMT-SVRs An iPad can connect to operate up to 253 cMT-SVRs, and 3 of the connected cMT-SVRs can be set as hot projects for instant switch in operation. ● Break with Tradition Embrace the Trend Through the integration of iPad and EasyBuilder, cMT Viewer, requiring no additional learning, break the public image of traditional HMI operation.

Sign crew in and out of the yacht with the CrewBoard app. It provides quick, easy, secure and mobile access to an overview of which personnel are on board. This is the digital age equivalent to the onboard white board. Simply add crew members. CrewBoard is designed to be as simple and reliable as the original white board has been for all those years but in a format that is more in line with today’s technology and needs of crew. With its graphically appealing interface and intuitive management system, adding new crew members, groups, subcontractors and day workers and accessing advanced features is simple and self explanatory. Full user profiles including names and job titles can be added and amended quickly and easily whilst profile photos can be selected from existing albums and libraries or taken directly via the device’s in-built camera and uploaded. CrewBoard at a glance: • Full user profiles • Image with user profile • Intuitive management system • Suitable for use on iPhone or iPad • Fleet functionality • Visitors functionality • In app notification
