The EM Display Protocol (EMDP) provides a standard set of console display states that represent each of the five Electromagnetic (EM) bands used by vessel sensor systems.

The display states are designed to be easily identified and distinguished from each other. Colours have also been chosen to correlate (where possible) with their associated band (eg the use of violet for the ultraviolet band).

The EMDP should not be confused with the Standard Designation Display Protocol (SDDP) which uses a different set of display states to represent variables in console visualisations.

Display States

The EMDP’s five display states are:
