ARINC 429 Output
The EFD1000 transmits the following labels on pins 26 and 27 (Note – some labels are
only transmitted when configured for an ACU installation). Labels 350 and 354 are
proprietary labels and should not be used for any purpose by any other third party
device.
Note – When connecting any third party device to this output it is the installer’s
responsibility to verify that the connected device does not have any adverse
effects from the labels below.
Note – The labels below are non-standard ARINC or GAMA labels due solely to the rate at
which the label is being transmitted.
Note- Except as shown in the wiring diagrams (Section 9) no ARINC 429 interface is
approved under the Aspen STC, and must be approved separately.

(1) These labels are only transmitted if fresh data is received from the selected GPS Source. As
such, the actual output rate is also limited to the rate which the GPS outputs these labels.
(2) These labels are only transmitted if the 429 OUTPUT PORT SPEED is set to HIGH. Other labels,
are transmitted if the 429 OUTPUT PORT SPEED is set to HIGH or LOW
*The label rate has a tolerance of plus 10% and minus 0%
