OmniBus® Family for CSDB

OmniBus CSDB

OmniBus CSDB refers to the CSDB serial communications capabilities available for all modular OmniBus platforms. OmniBus CSDB modules have 4 receive and 4 transmit CSDB channels, which can be combined with ARINC 429 channels on the same module.

OmniBus CSDB may be used for testing, simulating, and monitoring serial digital avionics equipment, including communication and navigation radios. It can also provide general purpose scheduled and asynchronous serial communications.

OmniBus Product Family

Ballard's OmniBus products connect computers or networks to one or more avionics databuses. Separate web pages provide information on OmniBus platforms (PCI, cPCI, PMC, VME, USB/Ethernet), avionics protocols (MIL-STD-1553, ARINC 429, ARINC 708, ARINC 717, and CSDB), serial ports (RS-422/232/423), and Discrete I/O.

Applications for OmniBus products include testing, simulation, and operational uses of avionics databuses. OmniBus products are built around an intelligent platform that can host one or more protocol modules. This flexible architecture accommodates mixed protocols, high channel counts, and unsurpassed processing power.

General

• Each CSDB module has 4 receive and 4 transmit (4R/4T) channels
• Programmable parity for each CSDB channel (odd/even/mark/space/none)
• Programmable parity for each 429 channel (odd/even/data)
• Programmable speed options:
• LO: 12.5 Kbps
• HI: 50 Kbps
• Custom
• Buffering schemes facilitate data handling:
• Single buffer is the default (receive/transmit)
• Ping-pong double buffers ensure data integrity (receive/transmit)
• Circular lists transmit a repeated pattern, such as a sine wave (transmit)
• FIFO list buffers can handle sequences of data (receive/transmit)
• Internal wrap-around self-test bus facilitates built-in test and diagnostics

Transmitters

• Vary the transmit amplitude under software control
• Messages scheduled according to bus parameters
• Continuous, non-continuous, and burst transmission supported
• Messages can be tagged for logging/interrupts

Receivers

• Automatically synchronizes with frame sync block
• Can receive continuous, non-continuous, and burst transmission
• Programmable filtering by label (address byte) and source identifier field (status byte)
• Automatic error detection:
• Bit error
• Parity error
• Frame error
• Detected errors can be logged and can generate interrupts

Sequential Monitor

• Create a sequential record in on-board memory or stream to file (with a simple program)
• Monitor concurrently with transmitter/receiver operation
• Monitor CSDB and ARINC 429 concurrently
• Monitor recording modes:
• Circular
• Fill and halt
• Each monitored message includes the label, status, data, channel number, and time-tag

Time-Tags

• Use 32-bit binary timer or 64-bit IRIG timer (displays day/hour/min/sec/ms/µs)
• IRIG timer options:
• Select IRIG-B or IRIG-A format
• Generate IRIG signal or sync up to an IRIG signal (on-board or external)
• Initialize timer to time of day or other value

Interrupts/Logging

• Configurable event log can be polled and can generate interrupts to the host PC
• The following events may be user-selected for logging/interrupts:
• When the monitor is full or halts
• On a user-specified frequency of monitored messages
• When tagged messages are sent or received
• When a message error is detected
• When a schedule halts or pauses
• When a schedule encounters a user-inserted Log Event command
• When a list buffer is empty or full
