Touch Screen Firmware V1001 (12 inch) and V1000 (15,17,19,24):

For Maritime Multi Display (MMD) / Industrial Standard Display (STD) units the touch screen signals are routed through

the display unit via the USB port and can not be controlled / detect status by the unit itself in any way. It means that even

if the unit was turned off by the front bezel Power ON/OFF function, the touch screen is still active and it will still send

touch screen signals through the pipeline.

This can be an issue to consider when you are cleaning the front glass. In order to avoid sending touch screen signals,

you have to either physically cut power to the unit, making sure that no lights illuminate, or disconnect the USB cable

physically from either computer or display unit. You may also disable the touch screen functionality from within the

Operating System (OS) or via customized functions from within applications running on the external computer you have

connected.

Touch Screen Firmware V1002 (12 inch) and V1001 (15,17,19,24,26):

Issue described above has been solved. For Maritime Multi Display (MMD) / Industrial Standard Display (STD) units

regarding cleaning of front glass, you have to be aware that in order to avoid sending touch screen signals to a

connected computer, you have to turn off the Display unit (via its front Power Symbol) and clean the front glass.

When done cleaning, simply turn on the Display again and Touch Screen controller is automatically re-activated.

To learn more about how to properly clean glass surfaces, review the “Ergonomics” section in the “General Installation

Recommendations” chapter earlier in this manual.
