DATAIR-400/M3(V2) Handheld ARINC 429 Tester

The DATAIR-400/M3(V2) is the next generation of the previous DATAIR-400/TR ARINC 429 handheld Tester.

The DATAIR-400/M3(V2) is aimed at providing the user with an easy to use first line diagnostic tool for testing and troubleshooting ARINC 429 avionics systems. It allows the user to connect to an ARINC 429 data bus and easily view the active ARINC 429 Labels on the bus or to generate up to 150 ARINC 429 test words to simulate a specific test. The receiver will automatically adapt to and display the bus bit rate.

The DATAIR-400/M3(V2) ARINC 429 Tester is a Hand Held unit that comprises an 8 line by 21 character backlit LCD, an alphanumeric keypad, a microprocessor controlled ARINC 429 receiver, transmitter board with a detachable rechargeable battery pack.

The DATAIR-400/M3(V2) instrument and accessories are supplied in a flite case, Part Number: DATAIR-400/M3(V2)/FC.

DATAIR-400/M3(V2) Handheld ARINC 429 Tester Detail

The DATAIR-400/M3(V2) features data entry in engineering units format for transmitted ARINC 429 data. Data values for up to 150 labels can be entered and the values and configuration can be stored in one of ten user profiles for easy and fast recall for different projects.

Standard labels held in non-volatile ROM can be recalled and saved as custom labels if required. These special labels can override the standard definitions if required. These custom labels can be suspended or deleted altogether if they are no longer required. The customised labels are also separated by the Hex ID -  Equipment Identifier as there can be multiple different definitions of the same label value.

We provide a software utilty for users that would prefer to define their custom engineering unit Labels on a PC. Further information can be found HERE.
