ARINC 429 Output
The EFD1000 E5 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 ACU 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.
