ARINC429 on iNAT devices supports additional Labels
15 October 2025
The iNAT-RQT and iNAT-FSLG system families are now available with additional ARIN429 label support.
iMAR Navigation provides an ARINC429 interface on its iNAT -Rx/-Fx/-Hx navigation system series. The iNAT -Rx/-Fx/-Hx series is a class of inertial measurement systems (IMS), which is made for a wide range of operation in navigation, timing, surveying, guidance and control. All systems of the system family iNAT-Fx, iNAT-Hx and iNAT-Rx as well as iPRENA-x systems and certain iCOMBANA systems follow the same internal hardware architecture and hence provide the same electrical interface (power supply,
communication and data interface, EMI/EMC protection).
The iNAT-Rx/-Fx/-Hx series supports as an option up to 4 hardware implemented bidirectional ARINC429 channels, which are available on system connector X2 (pins 21-36). High speed (100 kbps ±1%) and low
speed mode (12 to 14.5 kbps ±1%) is implemented on each channel.
On request, iMAR can add these systems also to the EASA Part21/G Capability List to provide them with EASA Form 1.
