M4 / M4h – 4.3″ Monochrome Display
The M4 family of displays, formerly known as the 260 family, have become invaluable in an extremely wide range of applications; from weather stations to machines literally at the coal face, boat engine displays to performance monitoring on rock crushers, and many more diverse applications.
Now in its 3rd generation of hardware, the M4, formerly the 260 and M4h, formerly the 261, multi-function intelligent displays have been sold worldwide. With thousands in service, they are possibly the most tested and widely used marine and industrial CAN bus displays in use today – rugged in its design with proven durability.
The M4, part of the M Series, is the market leading engine monitoring display with dedicated software specifically designed to work with the new breed of electronic controlled engines. With full DM1 and DM2 alarm management, as well as multiple languages and configurable display formats, the M4 unit is the foundation of many customised versions of Veethree displays in use globally.
The M4h is capable of operating at lower temperatures with a heated LCD module operating down to -40ºC. The M4 operates to -25ºC, with both operating to +75ºC.
The graphical user interface is easily configured to measure, display, store, process and transmit data using the powerful Software Developers Kit (SDK).
