The Sy629VME-BPE is a daughter module fit to the Sy629VME-BPM card and provides a convenient means for monitoring ARINC 629 bus traffic whilst providing extensive error detection & identification capability.

All features of the Sy629VME-BPM card are retained when the daughter module is fitted. The daughter module also provides the ability to insert a comprehensive range of transmit faults, while transmitting and receiving data in accordance with programme data written into the XPP and RPP personality memory.

The Fault Insertion and Detection facility provides enhanced error insertion and identification capability together with the ability to insert user defined errors into the ARINC-629 bus. The errors are inserted by writing pairs of words to the Error Insert FIFO. The first word defines the type of error and the second word defines where the error should be inserted, by reference to the XPP defined transmit schedule. Errors can be inserted at the word or string level.

Fault Insertion and Detection:

- Gap

- MID SYNC Transition

- Bi-Phase

- Parity

- High/Low Bit Count

Data describing detected receive errors is automatically placed in the Error Detection FIFO where it can be accessed by the user software.
