VME: Four/Eight 1553 channels VME board

Four/Eight x 1553 channels VME board For RT, BC and Monitor applications

Feature Summary:
MIL-STD-1553B Notice 2 compliant terminals.
Software compatible to DDC® Enhanced MiniACE® architecture.
Can be configured as 8 x single channel or 4 x dual-redundant.
32K or 64K Word RAM per channel.
VME Bus interface.
Provided with software API for Windows, Linux, QNX and Windows GUI for easy operation.
Low power consumption.
Bootable RT option required for MIL-STD-1760.
Simultaneous RT/MT Mode.
Low cost.

V-Orchestra™ Functionality
The module is designed as a general purpose VME bus based module with 8 or 4 channels of Mil-Std-1553 communication channels.

Two options are available:

Eight independent channels, individually programmable as RT, BC or Monitor with individual transceiver and physical media for each 1553 node, with 32K words RAM per channel, or
Four independent channels with dual redundant transceivers and transformers, individually programmable as RT, BC or Monitor, with 64K words RAM per channel.
The board supports five (5) programmable interrupt sources (IRQ3- IRQ 7 of VME bus).
Memory Base Address is settable through strapping options on the VME P2 connector, or at the P3 and P4 DB25 connectors.
LED Indications for Device healthiness and data exchange via communication channel are available.

Provided Software
Drivers, API
All Sital boards are provided with drivers for Windows, Linux and a high level API, which is provided as source code.

Luthier™ software is a Windows application, which enables testing and verifying basic operation of the board and 1553 connections.
It enables the user to configure the channels as BC, RT or Monitor, define 1553 messages and frames, monitor the traffic on the bus and validate the correct operation of the board.
This easy-to-operate program also provides information about energy reflections on the 1553 bus, which are caused by bad connections or lack of terminations.


Flexible Configuration
V-Orchestra™ boards are based on FPGA, and Sital’s proven 1553 IP cores and transceivers. This combination provides flexibility in configuration, modes of operation and features. Users can request different configurations such as combination of single and dual-redundancy channels, data transfer from one channel to another (1553 repeater functionality), and even support for other protocols such as H009 and PP194.
Please contact Sital for details.
