Sycos offers a comprehensive range of Arinc-629 Interfaces to VMEbus, covering both
Basic Protocol and Combined Protocol. Products supporting Basic Protocol are the
primary focus, as they support Boeing 777 avionics test, development and simulation
Sycos’ Multi Current-Mode-Coupler Device provides a cost-effective alternative to
using individual Current Mode Couplers, allowing up to five stub cable connections
per card. Arinc-629 terminals essentially communicate with eachother through their
System Interface Modules (SIMs) without a bus connection. Such communication is achieved
without loss of message or protocol integrity and is idea for use in test, development
and simulation activities. The unit draws its power from the stub cable connections
and does not therefore need any external power supply.
There are three main products supporting Basic Protocol:
• Sy629VME-BPM Transmitter and Full Bus Monitor
• Sy629VME-BPE Transmitter and Full Bus Monitor with Error Insert/Detect
• Sy629VME-BPT Multi-Terminal Emulator (up to 120 terminals)
These three products are well established and have been employed in many test, development
and simulation activities since 1991.
The Sy629VME-BPM card is also available in Conduction Cooled Format, which is supported
with VxWorks drivers.
The fundamental features of these designs are now employed in Sycos’ Arinc-629 PMC
interfaces, which are entering service in 2012.
