Established in 1986, Excalibur Systems started with an idea, and with a desire to create and achieve. The company designed the first ARINC-429 interface card for the personal computer; and it has not looked back since.

Today, Excalibur manufactures hundreds of products for the Avionics Industry. From connectors, cables, couplers and cards to sophisticated and complete systems, the company's commitment to customer service is legendary. Excalibur has received numerous awards, accolades and commendations for its products and more importantly for its service and support. Excalibur builds and maintains long-standing relationships with customers, which are addressed as "partners".

In today's fast paced technology market, it takes more than quality products to enable a company to consistently grow. It takes dedicated employees, who are willing and able to go the extra distance. That is the formula for success at Excalibur. More than seventy five per cent of the 45 employees have been with the company for at least ten years. This provides Excalibur with the stability to support and maintain relationships with its partners.

Accessories: Couplers, Repeaters, Bus Switches, Connectors, Cables & more

Box Couplers
Box Couplers and in-line couplers are the key components in the fabrication of your bus architecture. Excalibur provides a full line of standard couplers listed in the catalog as well as custom couplers to your requirements. The design for our products was implemented to meet the specification requirements as well as being aesthetically pleasing. If you have a requirement for couplers, Excalibur's products are cost competitive, with delivery from stock.

In-Line Couplers
IN-LINE COUPLERS are predominately utilized in airborne applications but can also be used where space is limited such as testers and simulators. Couplers are provided with a standard cable length but custom cable lengths can be procured at a nominal cost. The products were designed to meet the environmental requirements imposed by the military, including the temperature range of -55°C to 125°C.

Bus Switches
Bus Switches are devices that enable system architecture to be reconfigured. This reconfiguration is mostly accomplished in the test environment and includes but is not limited to simulation of missile firing and switching in or out a new section of bus interface.
Excalibur Systems is the only manufacturer of devices (ESI-R24/27/28) that contain their own TTL driver circuitry that allows them to be directly driven from a computer.

The ESI-1553RPT 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. The box was implemented using simple signal detection and switching techniques to minimize the delay through the device. Delay through the unit is in the range of typically of 700 nsec. to 900 nsec. maximum. Each connection to the bus is made through the implementation of a bus coupler in various configurations. Standard MIL-STD-1553 transceivers and digital signal processing are utilized to steer and shape the received signals, and retransmit them in the correct direction. Each of the two connections [J1 and J2] is bi-directional. Its type of connection is defined specifically in each configuration as marked on top of the box. A signal received at either connector will enable the signal to flow through towards the other connector. P1 provides the power connection to the device which is 12-36 VDC (28V nominal).The unit is intended to operate within the temperature range of -40º to 85º C.

Excalibur provides a variety of terminators that includes, 78 ohm, 3K ohm and others.

Dragon - PC/104 System
Excalibur’s Dragon is an advanced, ruggedized PC104 and PC104+ system in an enclosed, modular casing. The system is appropriate for use in data acquisition and recording for any combination of ARINC-429, MIL-STD-1553, Serial, Discrete or similar types of communication. The modular, stackthrough design of the PC104/PC104+ platform allows you to build a tailormade configuration based on Excalibur’s extensive range of boards while permitting the integration of other commercially available PC104/PC104+ cards. This modularity also enables the Dragon to be modified or upgraded at any time as technology and requirements change. The Dragon includes a processor card, a power supply and a selection of Excalibur’s ARINC-429 and MIL-STD-1553 boards. Each unit is heat sink protected, enabling an internal operational temperature range from -40°C to +85°C. The unit comes with military style waterproof connectors and seals between rings to impede water incursion as well as EMI/RFI protection to the inner electronics. Its compact footprint allows for versatility when space is at a premium.

Camelot is a ruggedized laptop computer featuring a full sized display that is able to operate in severe environmental conditions, such as water and dust. The unit has been designed to work with one or more of Excalibur’s PCMCIA cards. An optional chasis that allows PCI or PCI Express cards is available as well. The unit comes with the cards and software already integrated.

MACC - Miniature Airborne Communications Converter
When designing or upgrading avionics systems we are often faced with the task of integrating components that were not originally designed to work together.
A control computer that communicates using RS-232 may need to control component that expects MIL-STD-1553 messages or an INS may put out ARINC-429 labels, which are needed by Multi function Display designed around RS-422.
Faced with problems like these, integrators must choose between two poor options. They must either give up on one of the units in favor of another unit that may be less suitable but uses the appropriate communications spec; or they must add a computer system – often PC104 – which can translate from one unit to the other. These computers are generally large, heavy, hot, and require substantial power.
The MACC is a wholly contained Miniature Airborne Communications Converter. It contains an internal microprocessor, a dual redundant MIL-STD-1553 interface, three receive and one transmit (or receive) ARINC-429 channels, two serial channels (1 RS-232, 1 RS-232/422/485), 1 Ethernet (10/100/Gigabit) and 8 Discrete I/O signals (5 can be used as an RT address instead of Discretes) . The processor may be programmed to convert data in real time from any format to any other format. Its small size, weight, low power requirements and integrated heatsink make it an excellent candidate for solving airborne communications incompatibilities.
