BOHEMIA N.Y., 14 May 2009. North Atlantic Industries (NAI) in Bohemia, N.Y., is introducing MIL STD 1553 and CANBus functions for its VME, CompactPCI, and PCI multi-function boards for aircraft avionicsand similar applications.

Known as N7, N8 (MIL STD 1553) and P6 (CANBus) modules, they provide the mix-and-match capability to configure military avionics functions on one board. Other typical functions include A-D, D-A, S/D, D/S, LVDT/RVDT, DLV, ARINC 429 and 575, RS-422/485/232, Discrete and TTL I/O, reference generator, differential transceiver, and RTD.

The N7 and N8 modules provide two dual-redundant MIL STD 1553B Notice 2 interface channels. Each channel can be configured to act as a Bus Controller (BC), remote terminal (RT) or monitor (MT). They include 128-kilobyte (64K words) on board memory per channel, register compatibility with the SµMMIT family of devices from Aeroflex Inc., support for automatic message return, and automatic health monitoring (BIT).

The P6 module provides four independent, isolated, channels of Control Area Network (CAN) serial data bus links, conforming to the ISO 11898 international standard. Both CAN A & B are supported. CANBus support is implemented with the Bosch FPGA core. Its stack design conforms to the SAE J1939 protocol specification, with address claiming option. It has ANSI C Compliant Network, Transport and DataLink layers. Has include Self-configurable, Non-Configurable and Command Configurable ECU settings. Continuous Health Monitoring (BIT) is provided.

The N7, N8 and P6 functions are supported on VME, cPCI and PCI multi-function boards with operating temperature ranges of -40 to 85 degrees Celsius and 0 to 70 C.
