cNODE Maxi - Transponder

The largest members of the cNODE® transponder family.

Typical applications utilising the Maxi transponder as a DP reference solution and for subsea construction operations.

The cNODE Maxi design is very modular and covers a large range of  applications with its variety of different transducers, internal and external sensors, housing materials and other add-on functions.

New configurations and software can easliy be downloaded from the Transponder Test and Configuration unit (TTC30) without opening the transponder.

The floating collar and release design make the launch/recovery operation safe and easy. Spare parts for cNODE are based on the main modules.

    standard deviation):
    — Range accuracy: 0.02 m
    — Repeatability: 0.01 m
  • Acoustic data link for command and data transfer
  • Internal tilt sensor ± 90°; accuracy ± 2°
  • External connector for transponder configuration and software
    update via serial line (TTC30)
