IntelliBus is a Boeing-developed serial databus communication standard designed to network sensors, actuators, and subsystems while providing the simplicity necessary for miniature smart sensors, the low latency needed for flight controls, the time determinism required for data analysis, and the distance for industrial control. IntelliBus permits the integration of signal conditioning, analog-to-digital conversion, and digital interfacing into a low-cost package that can be installed in any sensor, actuator, interface module, or system. Aeroflex Colorado Springs (Aeroflex) licensed the IntelliBus standard to market products in 2004. IntelliBus has a low overhead that enables maximum data transmittal, accommodates both sensors and actuators for monitoring and control, and incorporates fault avoidance features. Additionally, IntelliBus accommodates a high sensor count per bus (over 500), allows synchronization between multiple busses, simultaneous sampling capability, and isochronous transmission with low jitter (+/- 500ps). IntelliBus is time deterministic and enables high data rates per bus (30, 15, and 7.5 Mbps) while maintaining a low cost-per-node. Aeroflex has developed a Network System product family consisting of a Network Interface Controller (NIC) and a Network Device Interface (NDI) to address a variety of communication and control network requirements in the Factory Floor Automation and In-Vehicle Health Monitoring fields. Features include: A standard set of functions and services that locate, configure, and operate a wide range of transducer devices A mechanism to acquire and distribute data: • Synchronously • At multiple sample rates • Simultaneously with minimal acquisition jitter Minimal network latency without strict constraints on communication at the peripheral device Support of device (node) memory containing node information and automatic peripheral configuration (at boot) Multi-cast connectivity to a large number of peripheral devices A mechanism for any node to filter and trap network data Low-overhead time-deterministic device-todevice data transfers Data buffering to minimize network latency Low-cost, EMC compliant physical layer: easymaintenance twisted-pair copper Capable of 30 Mbps data rate Scalable hardware, firmware and software A. Physical and Data Link layers (OSI layers 1-2) Per the product features listed above, twisted pair copper wiring is utilized with M-LVDS (Multipoint-LowVoltage Differential Signaling) data transceivers for high-speed (30 Mbps) signaling, or RS-485 transceivers for lower speed applications. Off-the- shelf transceivers are used. Due to proprietary bit sampling schemes in the receiver, no clock recovery or re-syncing is necessary in the physical layer (layer 1), only signal level translation and output tri-stating is required. The typical Aeroflex NIC/NDI network system consists of one bus controller and multiple nodes. Half duplex data transmission occurs, where only the bus controller or the addressed node is actively transmitting data. More than one node may be receiving the data. (Full-duplex communication is possible on a single controller-to-node system. The Data Link layer (layer 2) support is provided by two hardware functions: the Network Interface Controller (NIC) and the Network Device Interface (NDI). The AX7000 Network Interface Controller (NIC) The NIC function is the master bus controller for the Aeroflex NIC/NDI network. Connecting directly to a physical layer transceiver, the NIC controls the scheduling of data communications on the network by issuing commands to the NDI devices on the network. Typically a PCI card in a host PC, the NIC uses a set of IntelliBus protocol NIC opcodes which allow host modification access to the NIC scheduler, as well as direct access to network data. The AX30 Network Device Interface (NDI) The NDI function is the miniaturized interface chip connecting peripheral devices onto the Aeroflex NIC/NDI serial network. The IntelliBus protocol allows each NDI device to support up to 16 peripherals (or channels). These peripherals can range from simple sensors or indicators to complex audio/visual components. With 30 Mbps of throughput on the physical bus, many NDI chips can be supported on a single Aeroflex NIC/NDI network, with the maximum addressable range of up to 509 channels per bus. B. Presentation layer (OSI layer 6) Included in the NDI is support for serial data communications with peripherals via SPI, ISC, I2S and UART ports. The number of ports (channels) available within a specific NDI determine the pin count and size of the device; thus, a range of NDI device package sizes supports a variety of peripheral area constraints. Input and output FIFO buffering is provided within the NDI to support the difference in data rates between the peripherals and the highspeed Aeroflex NIC/NDI traffic rate. C. Application layer (OSI layer 7) Included in the NDI is flexible support for a large variety of signal processing and signal conditioning devices, such as: Analog to Digital Converters Digital to Analog Converters Microcontrollers Digital I/O (switches, indicator drive) Inter-node communication Standard Products AX7000-NIC Network Interface Controller (NIC) Preliminary Datasheet- May 2005 www.aeroflex.com/mixedsignal FEATURES Supports IntelliBusTM Protocol v3.0 Dual IntelliBus Network Ports Full and Half Duplex Support IntelliBus RS-485 Physical Layer Synchronous Data Rates up to 15.0 Mbps Asynchronous Data Rates of 7.5, and 15.0 Mbps 256K Word Schedule Memory 256 Word Dynamic Schedule Register Space 1K Word Deep Receiver FIFOs External IntelliBus Power Source APPLICATIONS Sensor Integration Factory Floor Automation In-Vehicle Healthy Monitoring Process Control Systems BENEFITS Network Interface Controller (AX7000-NIC) Capable of running network schedule Provides gateway to other higher networks Supports up to 510 logical addresses of sensors, actual tors, and IICs per bus Host processor can directly talk or control IntelliBus schedule via NIC Runs membership services functions Provides synchronous trigger time-base Contains network traffic FIFO buffer Multiple form factors available (PCI user specified) GENERAL DESCRIPTION The AX7000-NIC Network Interface Controller (NIC) is a third generation controller design specifically to be used as a controller in a PC based IntelliBus development system. The card plugs directly into a 66Mhz, 32-bit 3.3V PCI V2.2 compliant slot in a Pentium PC compatible computer. The card supports two semi-independent IntelliBus serial channels, which operate in asynchronous mode supporting the IntelliBus Isochronous (IS) communications tier at data rates up to15Mbps. The IntelliBus network channels are implemented using the IntelliBus RS-485 physical layer and can be configured in a Half or Full Duplex arrangement. The card contains a 1K word deep FIFO for each of the two network receiver channels. This allows real time data collection using a standard PC operating system. All control and data retrieval operations are handled by software through registers implemented in the PCI interface. The card supports a custom microcode instruction set that is used to control the execution of a schedule. The microcode is loaded, by software, into onboard schedule memory. The card contains status lights for a real time indication of the state of the network. The NIC controls all I/O from an Interface Card. The AX7000-NIC is manufactured at Aeroflex Colorado Springs’ 104,000-square foot ISO-9001 certified facility. Aeroflex Colorado Springs has been producing high-reliability integrated circuits and circuit card assemblies for the aerospace industry since 1980. Figure 1.

The flash interface is implemented as a standard SPI interface. Remote ID Inputs The AX30NDI contains support for ID inputs which can be read by the IntelliBus Network Interface Controller to determine the physical location of each NDI located on a bus.
