Intelligent ARINC 717 Interface ModuleEletter Product
The M4K717 is an intelligent ARINC 717 interface module for the multiprotocol Excalibur 4000 family of carrier boards. The module supports two ARINC 717 receive channels and two transmit channels. In transmit mode, the module sends the four subframes from a pre-defined buffer in dual-port RAM. In receive mode, the module stores all subframes with status and Time Tag information appended to each subframe.
The ARINC 717 bus defines the communication between DFDAU (Digital Flight Data Acquisition Unit) and the DFDR (Digital Flight Data Recorder). The Data over the bus is a collection of all various data to be recorded.
The EXC-4000 carrier board series was developed to meet the needs of avionic testers for multi-protocol integrated, digital bus testing. Modules may be selected out of a growing list which currently includes MIL-STD-1553/1760, MMSI, H009, ARINC-429, ARINC-708/453, Serial (232/422/485), ARINC 825, Discrete and CAN bus. Additionally, an IRIG B decoder implements a global time stamp relative to the IRIG B pulses. The need for higher density, different protocols, and multi-channel on one integrated test card has made the EXC-4000 series very successful.
