OmniBus 1553 PMC
OmniBus 1553 PMC has the power and flexibility to operate as a simple or intelligent 1553 interface card or as an embedded processor. Its on-board PowerPC processor and ability to run user programs make the OmniBus 1553 PMC unique among PMC cards. It is available with either convection cooled front panel or conduction cooled rear panel I/O. Though not modular like other OmniBus products, it has all OmniBus 1553 features in one or two 1553 channels and a variety of configurations.
OmniBus products are built using an integrated board, core, and module architecture. PCI, cPCI, and Ethernet/USB boards include 1 or 2 cores, VME boards have up to 4, and PMC boards include a single fixed core. Each on-board core has a dedicated protocol processor, IRIG timer, and 3 sync and 3 trigger lines. These cores are the support circuitry for the I/O modules, which contain the interface to the databus protocol(s). Isolating the protocol interface on the I/O module provides the flexibility to create custom, user-specified configurations for single or mixed protocols. The protocol-specific OmniBus architecture provides a better solution with greater performance than general-purpose modular systems (such as IndustryPack™).
