The DATAIR-400/TRm Handheld ARINC 429 Data transmitter and analyzer is an easy to use diagnostic tool. It connects to an ARINC 429 data bus for instantaneous display of the active Labels on the bus - without any preset conditions. The ARINC 429 data word associated with a displayed Label can be viewed by simply positioning the cursor over the desired displayed Label and pressing the SELECT button. The display will then show the ARINC 429 word in binary or engineering unit format, the rate of occurrence on the bus in milliseconds, the SSM value and the Parity bit. The monitor will automatically adapt to and display the bus bit rate. Further filtering on the selected Label can be obtained by selection of the SDI field. In addition to having the same receiver features as the DATAIR-400, the DATAIR-400/TR allows the user to generate up to 16 ARINC 429 Labels to simulate a specific test.

DATAIR-400 ARINC Data Transmitter

Model  Description 
DATAIR-400  ARINC 429 Data Analyzer. Data Bus Monitor.
DATAIR-400/TRm ARINC 429 Data Transmitter and Analyzer.

The DATAIR-400/TRm ARINC data transmitter allows the user to set up a maximum of 16 ARINC 429
labels for transmission and to modify the transmitted data field for each Label (bits 9..32) in real time.
The data field on the first Label can be edited to ramp up and then down by one LSB increment at a
time. Labels to be transmitted are selected in Octal.
The frequency and interval of the transmitted word can also be set. Single shot mode is also available.
Edited binary data is displayable as a hexadecimal value in real time for those users who require this

ARINC 429 Receiver:
Very simple to use intelligent ARINC 429 Real Time Data Monitor.
Automatic Bus search with automatic bus speed selection.
User definable Engineering Units Display.
