The JcAir T1200B is an ARINC 429 Control Display Unit designed for testing ARINC 700 series line-replaceable units (LRUs) and avionics equipment. Operating as both a bus analyzer and signal simulator, it measures and interprets avionics system outputs while generating controlled test inputs. The unit decodes navigation and communication data including VOR, ILS, ADF, VHF, HF, DME, and LRA associated words, translating BCD and BNR data into engineering units.
