Important Notes

  • With the introduction of version 1.10, the converter now supports a system with a Autopilot.  With version 1.11 you are now able to connect and communicate with a previous generation of Autopilot such as the S1G, S2G and S3G as examples.  Information in the manual regarding not being able to connect the converter with a Autopilot in the system is now redundant.
