GoFree Developer Toolkit


The GoFree Developer Toolkit is completely unique as, for the first time ever applications can be created which allow information from a Simrad network to be included as part of a wider program.


Open Protocol

The GoFree open protocol data strategy groups data into 5 different Tiers. Access to data varies, but essentially all data is free to use if it enhances the desirability of Simrad MFDs. 

Specifications for Tier 1 and Tier 2 (view only) are available to download for free - follow the links below. Any developer wishing to use Tier 2 control or Tiers 3 to 5 should contact [email protected] with a proposal.Support for Tiers 2-5 will be included in the Simrad NSS RTM3 Software release, available from late 2012.

Prior to the RTM3 software production release, a special “developer’s build” will be available for testing against.  It is important to note that Simrad retains the right to change the Tier 2 specification prior to the features being enabled in the first production release.
