The M4 CAN bus display family are designed as an OEM (Original Equipment Manufacturer) product, and are not available direct to end users. Formerly known as the CANvu 260/261, Veecan 260, and Teleflex Kantrak 2700/2710 the displays 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 and M4h, the multi-function intelligent displays have been sold for decades worldwide, model names have changed over the years but hardware compatibility has been maintained.

Compatibility Quick Reference Check

  • M4 previously our CANvu 260, compatible with the 2700 from Kongsberg, and 7200 by Seastar
  • M4h previously our CANvu 261, compatible with the 2710 from Kongsberg, and 7210 by Seastar

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 has a standard Engine Monitor application available 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).
