I. Aspire-200 Connections to Aircraft
The Aspire-200 communicates with various systems in your aircraft to c
ontrol the
antenna and distribute resources to its subsystems.
(1) Power
28V aircraft power supplies the HDU, the IPLD, and all the antennas except
the Om
ni Blade antenna and the AMT-3500 IGA (115 VAC).

The HDU provides three standard connections to the navigation systems on
the aircraft. Each connection can accept labels from:
•Inertial
• GPS (GNSS)
• Hybrid
•FMS
•AHRS.
Table 2-3 provides the IRS ARINC 429 bus labels and associated data types.
Table 2-4, Table 2-5, Table 2-6, and Table 2-7 provide alternative data types.
For more information about the labels, refer to Appendix 10 of the ARINC 704-7,
Inertial Reference System document and ARINC Specification 429-ALL: Mark
33 Digital Information Transfer System (DITS).
The priority of navigation labels is:

The HDU does not require heading, pitch, and roll labels when operating with
an LGA.
