ARINC 629 VME Multi-Terminal Emulator with Error Insert/Detect Module

The Sy629VME-BPTE card is an ARINC 629 to VMEbus interface packaged in a standard 6U, single slot format and provides a cost effective means for emulating up to 120 ARINC 629 Terminals, transmission and reception, with full data bus monitoring, through a single connection to the ARINC-629 data bus. This product is a firmware upgrade to the Sy629VME-BPT card.

With a single connection to an ARINC 629 data bus, the card provides facilities to add and delete terminals to/from the bus 'on-the-fly', whilst preserving the protocol. Emulated terminals compete with true terminals for bus access, in accordance with Basic Protocol. Important features such as refresh counter support and CRC checking are embedded in the design.

The features and facilities of the Sy629VME-BPM card are embodied within the design of this product, making it a most comprehensive facility for most applications using Basic Protocol.

The product is well established and is supporting many commercial, in-service, Boeing 777 full flight simulators.

- Fault Insertion and Detection

The Error Insert and Detection facility provides enhanced error detection together with the ability to insert user defined errors onto the ARINC-629 data bus. These errors can be inserted at either the string level or the word level.


String errors are realised by substituting the wordstring for a given XPP location by the wordstring defined by an alternative XPP location. This can be used to alter some of the parameters of the XPP cell and thereby create an error.


Word errors are divided into five types, namely:



- MID SYNC transition

- Biphase

- Parity

- High/Low bit count


The enhanced error detection facility checks for correct:



- SYNC waveform

- Biphase on data and parity

- Parity
