OmniBus Discrete I/O

OmniBus Discrete I/O refers to the standard avionics discrete and general-purpose digital IO capabilities available for all modular OmniBus platforms. Each OmniBus Discrete I/O module has 32 IO lines configurable as inputs and/or as outputs. Inputs have programmable thresholds and debounce filters, and outputs have protection circuits and can sink up to 200 mA.

OmniBus Discrete is used to sense and control discrete signals in a wide range of applications with up to 40 VDC.

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.

OmniBus Discrete provides interface capability for standard avionics discretes and general-purpose digital IO. OmniBus Discrete has many programmable features that facilitate its use for sensing, controlling, and testing DC circuits at voltages up to 40 VDC. Each of the 32 IO lines may be configured as as an input and/or an output. The input of an IO line can be used in conjunction with its output for built-in test (i.e., to verify the state of the output) or to sense the state of an ORed circuit. Inputs can be configured as series (voltage/open or voltage/ground) or shunt (open/ground) with a programmable threshold voltage suitable for use from TTL level through 28 VDC. The debounce feature filters the input to eliminate excessive transitions. Outputs are open collector and can sink up to 200 mA. Protection circuits permit switching of inductive loads and will shut down the output driver in over-current or over-temperature conditions.

The Downloads section contains data sheets with complete information on Discrete I/O functionality for OmniBus products.

PCI AND cPCI

The OmniBus PCI and cPCI boards can host 1 or 2 on-board cores with circuitry to support 1 or 2 protocol modules. Because each on-board core has its own dedicated DSP, the OmniBus PCI/cPCI boards can host up to 32 ARINC 429 channels without relying on the host processor or risking data loss from an overloaded DSP.

Ethernet/USB

The OmniBusBox device hosts 2 on-board cores with circuitry to support 2 protocol modules. Because each on-board core has its own dedicated DSP, the OmniBusBox device can host up to 32 ARINC 429 channels without relying on the host processor or risking data loss from an overloaded DSP.

 

VME

The OmniBus VME boards can host 2 or 4 on-board cores with circuitry to support up to 4 protocol modules. Because each on-board core has its own dedicated DSP, the OmniBus VME boards can host up to 64 ARINC 429 channels without relying on the host processor or risking data loss from an overloaded DSP.

BTIDriver API

Users can develop their own software using the included Application Program Interface (API) to quickly develop custom applications. OmniBus products can be easily configured and operated with only a few API calls. The comprehensive library also includes a broad range of functions for specialized needs.

PowerPC

An SDK is available for advanced users who are developing software to run on the PowerPC (available on OmniBusBox, OmniBus VME, and OmniBus PMC).

 

Drivers

Driver software is available for Windows®, Linux®, LabVIEW, LabVIEW RT, VxWorks®, INTEGRITY® and other operating systems. Availability varies by product. Contact Ballard for specific details for your desired Omnibus product.

OmniBus Part Numbers

The part number for an OmniBus product is a combination of the platform number, module number(s), CoPilot code, and options. This results in thousands of possible part number combinations. Contact Ballard sales for assistance in determining the best OmniBus order number to fit your needs. Each platform core can accept one module. A core without a module may be used for future expansion.
