This Synchro to ARINC 429 HS Converter (933800-24) is a general purpose converter, which can be used whenever Synchro to ARINC 429 High speed conversion is required. It can receive three 3-wire Synchro ARINC 407 inputs: pitch, roll and magnetic heading. The received labels are then converted to ARINC 429 high speed. The output labels are: 320 (Magnetic Heading), 324 (Pitch) and 325 (Roll). This converter also receives 3 discreet flag inputs which are used to enable or disable the output of ARINC 429 labels associated with roll (325), pitch (324) and magnetic heading (320).
In addition, the converter outputs a “canned†discrete label 270 with data bit 14 set to a valid (1) state and all other data bits set to zero (0). The converter contains a strapping input, flag 4 that when strapped high (28VDC) disables label 270 output.
