Autopilot Support

GRT Autopilot Support


Autopilot interface software is part of the display unit software. However, the servos may need to be updated from time to time as the display unit software changes.   The software in each servo is updated with a USB stick using the same procedure as the display unit. Use the Software Update function on the A/P Maintenance page to send the new software to the servos.

Release Date
Current Servo Software  13/14* 3/21/2013

*Note on V. 13/14 – Versions 13 and 14 are both current. Version 14 is functionally the same as Version 13 and was created to adapt to the newer style PIC chip. If an update to servo software is required, the system will automatically detect the chip type and install the version appropriate for the servo. The March 21st software release only reflects this combination, and is not a routine software update for autopilot operation. (In other words, if your servo software is Version 13, it IS current and it will not update to Version 14 because Version 14 does not apply to it.)
