1553 bus analyzer

Our new inline Bus Monitor is a very small, very light MIL-STD 1553 Bus Monitor that can be connected to any Windows device with a USB connector. It monitors and records all or selected 1553 traffic for later analysis or reconstruction in the lab using Exalt Software.


Flight Sim

Now Test your products using a real flight simulator for more accurate data.

Package includes:

  • Flight Simulator
  • MACC protocol converter
  • 429 or 1553 USB/Ethernet Interface
  • EXALT Plus



USB / Ethernet

The EXC-1553UNET/Px and the DAS-429UNET/RTx are intelligent, MIL-STD-1553 & ARINC-429 adapters. Its small size and ability to interface through USB or Ethernet interfaces make it a complete solution for developing, testing and performing system simulation of the MIL-STD-1553 & ARINC-429 buses, both in the lab and in the field.


1553 Mini PCIe

This card’s small size and suitability for Mini Card compatible computers make it a complete solution for developing, testing, integrating 1553 interfaces and for performing system simulation of the MIL-STD-1553 bus, both in the lab and in the field.



Fully Integrated

An advanced, ruggedized PC104 and PC104+ system in an enclosed, modular casing. The system is appropriate as a mission computer or for use in data acquisition and recording for any combination of ARINC-429, MIL-STD-1553, Serial, Discrete or similar types of communication.



Protocol Converter

The MACC is a complete Miniature Airborne Communications Converter (data converter) designed to convert between different avionics communications specifications, such as: 

MIL-STD-1553/1760, ARINC 429, ARINC 825, Serial (RS-232/422/485), NMEA, Discrete I/O's, Ethernet & more.



Mini Data Recorder

Excalibur’s MARC is a complete Miniature Airborne ReCording system designed to record messages of several communication protocols:

♦ MIL-STD-1553 / 1760

♦ ARINC-429 

♦ Discrete I/O's



MIL-STD-1553 Repeater

The ESI-1553RPT MIL-STD-1553 Repeater box was developed for customers who need to extend the existing length of their bus or provide the capability to utilize long stubs or to connect a number of devices to a single stub.
