The 429EX ARINC 429 Databus Analyzer provides avionics technicians and line maintenance personnel with an easy method for troubleshooting ARINC 429 labels. It has the capability to selectively trap labels three different ways. The 429EX has a non-volatile memory and features user-selectable ARINC Air Transport Equipment Identifier Codes. Transmitted and received data can be viewed in either hexadecimal or easy-to-understand engineering format.
The 429EX is housed in a rugged, compact case with internal, rechargeable NiCad batteries. The unit comes with either a 110V or 230V plug-in battery charger. An optional carrying case is available (sold separately) for convenience and protection of the unit.
