The making of MIL-STD-1553 and related products
Category : MIL-STD-1553
The MIL-STD-1553 was first used with military avionics under the Depart of Defense of the United States in defining electrical, mechanical, and functional features of a serial data bus. With time, however, civil avionics adopted it in their on-board data handling (OBDH) subsystems. Over the years, its revisions have allowed its use in ships, combat vehicles, missiles and satellites.
The military standard cards come in two functions. The single function works as Remote Terminal, Bus Monitor or Bus Controller. On the other hand, the multi-function is equipped with various features that enable it to work as a multiple Remote Terminal and a Bus Controller at the same time. It also functions as a Triggerable Bus Monitor.
Ethernet Adapters
There is a couple of MIL-STD- 1553 adapters. While both are small-sized and can interface through Ethernet interfaces, the USB EXC-1553UNET/Px adapter functions either as a single or a dual channel while the Rugged ES-1553RUNET/Px can work as multiple Remote Terminals and a Bus Controller at the same time or a Triggerable Bus Monitor. Both adapters are designed for optimum lab and field developing, testing and simulation of the performing system of the MIL-STD-1553 bus.
Two Dual Redundant Channel Card Interfaces
There are different card interfaces supporting dual redundant 1553 channels – the EXC-1553ExCard/Px, the EXC-1553PCMCIA/Px and the EXC-4500ccVPX/xx. They work with computers equipped with Express Card, PCMCIA and VPX respectively.Owing to their small size they are suitable for simulation of the MIL-STD -1553 bus whether in the field or in the lab.
Four Dual Redundant Channels Card Interfaces
Card interfaces in this group include the EXC-4000cPCI/xx card working with Compact PCI computers as well as the EXC-4000P104Plus or the xx card for PC/104 Plus computers. They are compatible with all ordinary versions of MIL-STD-1553—A and B. Moreover, every channel supports BC and RT modes of error injection and all modes of error detection.
Mini Card
Small in size, the Mini CPIe card works perfectly with computers designed for use with mini cards to deliver great solutions in the development, testing and integration of 1553 interfaces and system simulation performance of the MIL-STD-1553 bus. In addition, it supports error detection and injection.
Four Multi-Function Channels Interface Boards
The EXC-1553ccPMC/Px and EXC-1553PMC/Px support up to four channels for computers compatible with PCI Mezzanine Card. They have both single function and multi-function capabilities. Additionally, they support error detection on all modes and error injection in BC and RT modes.
Eight Dual Redundant Channels Cards
The Tx M4K1553PxS, the EXC-4000VXI/xx, and the EXC-4000VME/xx works with computers equipped with VME and VXI. Their modules are the M4K1553Px. In addition, they are compatible with the ordinary MIL-STD-1553 variations including A and B. Every channel has the support of error detection in all modes as well as BC and RT modes of error injection.
Multi-Protocol Boards
The boards in the EXC-400 series were developed when it was realized that avionic testers needed digital bus testing with multi-protocol integration. The available modules include H009, ARINC-708/453, MIL-STD-1553/1760, Discrete,ARINC-429,CAN bus, MMSI and the 232/422/485 Serial. Their greatest features lie in availability of different protocols, higher density and a multi-channel in a single test card.
Conclusion
It should be remembered that most of the interface cards features can only be found on full size testers. However, they are small enough to allow use in both the lab and the field. These qualities serve to add to a great user experience.
