SBS Avionics Technologies announces the introduction of its ARINC 429 interface board for cPCI backplanes. The board is ideal for embedded avionics applications.
"The ARINC 429 cPCI interface is an excellent addition to SBS Avionics ARINC line of products," said Rick Schuh, President of SBS Aerospace Group. "The cPCI 429 product expands SBSí offering of the most advanced ARINC 429 product family, which includes ISA, PC/104, PCI, PCMCIA, and VMEbus."
How It Works
The A429-cPCI interface provides the user with 8 highly programmable ARINC channels over the cPCI backplane. Each channel is software configurable for transmit or receive, high or low speed (12.5k or 100k bits per second) and ARINC 429 or 575 protocol requirements. Source lists may be transmitted by any channel. Sink data may be filtered and received in a current value table, local monitor and/or global monitor buffers. The ARINC data word may be identified and sorted by either Label or Label/SDI. The onboard DSP controls the flexible data structures, triggers, interrupts, time stamping and data communications on the 429 bus. External triggers may be used for synchronization while the advanced interrupt technology allows real-time event handling by the host processor. As each 32 bit ARINC 429 data word is received, it is time stamped with a 48 bit, 1-msec time tag. When the receive channel is placed in the monitor mode, the time stamped data is accompanied with a 16 bit status word which provides error information regarding each received word. When a channel is setup as a transmitter, any number of label sequences may be sent on each channel and all transmit channels may be synchronized for simultaneous transmission. Each ARINC word to be transmitted has an accompanying control word used to implement various error injection capabilities. Words may be transmitted in scheduled and/or asynchronous priority methods. SBS' ARINC 429 interfaces are available with the optional Williamsburg Protocol on board. This breakthrough in technology provides for firmware implementation of the file transfer protocol. The firmware matches channels and handles all handshaking. File transfer status, error indication and multi-try methods are handled by the interface; interrupts may be used to notify the host of the interface's status. These features provide a resilient protocol handler, requiring very little host CPU attention. About SBS Avionics Technologies
