The configuration of the module can be changed by connecting it to a compatible GRT EFIS. The
configuration data is stored in the GPS module, allowing it to operate stand-alone after it is configured.
Unless specified in the setup for a particular transponder or UAT setup, the above settings should be
used.
EFIS Configuration Settings
When the Safe-Fly is wired to a GRT EFIS (other than a HS or WS display unit), one serial port on the
EFIS display unit must be configured for this module. Since the GPS includes a serial port combiner,
the EFIS will provide you with additional serial ports via the Safe-Fly GPS inputs.
Using the “Set
Menu”, “General Setup”, configure the serial port on the EFIS that is wired to the “Serial
Control Input/Output” as “Safe-Fly GPS and SPC”, at 115,200 baud.
After saving these settings,
the General Setup menu will show additional settings associated with this module. They appear just
after the serial port configuration settings.

GRT Safe-Fly GPS
To use this GPS as a navigation source to the EFIS, set
it to “GPS1”, or “GPS2”. If not used as a navigation
source to the EFIS, set it to “Not Assigned”. Note that
the EFIS supports 2 GPS inputs, and only one GPS
input can be assigned to GPS1 or GPS2, so it may be
necessary to change an internal GPS input to “Not
Assigned”, or a serial input configured for GPS1 or
GPS2 must be set to “Not Used”.
