ARINC 429 bus testing device

This handy device allows the quick check of all to an ARINC429 bus connected units, either transmitting or receiving.

Questions, like which bit is changing when a certain state is reached in the aircraft, or how specific data are scaled, are easily answered. But also the simulation and display of ARINC429 data, like the altitude or the speed is possible without any problems.

The entire handling is effected via 3,5 touchscreen display, which is also well readable at daylight. An accumulator allows a total employment of 45 minutes without any external power supply.

The test signals are getting connected via customized cables or breakout boxes.
