3.2 ARINC429 Interface
AT-1 is capable of interfacing with other aviation instruments by sending an ARINC429
signal on its ARINC429 output.
AT-1 is compatible to a wide range of avionics systems using ARINC429 hardware interfaces.
Please consult the section ‘‘Compatibility Considerations’’ on page 29 for details.

The ARINC429 interface consists of two data wires. The differential high-speed signal
requires twisted pair shielded cables, e.g. MIL-C-27500-22TG 2T14.
3.3 WiFi Interface
AT-1 features an integrated WiFi interface through which personal devices like tablets,
smartphones, or computers can connect to AT-1.
AT-1 is compatible to a wide range of aviation apps for traffic display. Please consult the
section ‘‘Compatibility Considerations’’ on page 29 for details.
3.4 Data Bus Interface
AT-1 uses a CAN data bus interface to connect to other AIR Avionics devices such as for
example traffic display units.
Only AIR Avionics articles intended for use with AT-1 may be connected to the data
bus.
