OPAL-RT provides a MIL-STD-1553 driver for serial communication of data between the simulator and all devices in a typical 1553 bus network. The solution is based on an Abaco Systems RPCIE-1553 High Density PCI Express Interface and can be configured to interface with and access all functionalities, for any type of device:

• Remote Terminals (RT): passive devices used as interfaces between the bus and the hardware that should interact and connect to it.

• Bus Controller (BC): a unique device that manages transfers to the bus and preserves the deterministic aspect of 1553 transactions.

• Bus Monitor (BM), a passive device that simply listens to the 1553 transactions. The validation of a single device, in a loopback configuration, is also possible without the need for extra RT, BC, or BM devices.

MIL-STD-1553 is a military standard widely used in avionic systems. It defines the mechanical, electrical, and functional characteristics of a serial data bus. The standard has become one of the basic tools being used today by the Department of Defense for weapon systems integration. Some of the key MIL-STD-1553 elements are the bus controller (BC), the embedded remote terminal (RT), which is a sensor or subsystem that provides its own internal 1553 interface, and the stand-alone bus monitor (BM).
