Excalibur Systems was established in 1986 and from the outset, their intention to create and achieve notable accomplishments in the field of avionics was observable. Among other remarkable initial achievements, they designed the first ARINC-429 interface card for the personal computer and they have become an industry leader by manufacturing hundreds of products for the avionics industry. Included among their superb products, are their lines of connectors, cables, couplers and cards. However, their specialty lies with designing and manufacturing sophisticated and comprehensive systems. Besides displaying a unique commitment to customer service, Excalibur has earned numerous awards, accolades and commendations for their products and more importantly for their customer support, based on their philosophy of building and maintaining long-standing relationships with their customers, who they refer to as “partners”.

Today, when the markets are fast paced and customers demand more than a quality product, it takes dedicated employees, who are willing and able to go the extra mile for the company to continue growing and succeeding in these competitive niches. What makes Excalibur so successful, among other things is the fact that more than seventy five per cent of their employees have been with the company for a decade or longer. This unique relationship makes Excalibur more of a home than a working place and provides the stability needed to support and maintain relationships with its “partners”.

One of Excalibur’s flagship products, the EXC-1553 PCMCIA/B is an intelligent MIL-STD-1553 interface card for PCMCIA equipped computers. Its compact dimensions and compatibility with notebook computers make this MIL-STD-1553 interface card the perfect solution for system simulation performance of the MIL-STD-1553 bus, both in the lab and in the field. The EXC-1553PCMCIA/B can be programmed to operate as a Bus Controller, Remote Terminal, and Remote Terminal/Concurrent Monitor. The internal 64K word dual port RAM provides sufficient memory for advanced test and simulation requirements. Card operation may be programmed in real time.

Another one of Excalibur’s many achievements is an ARINC-429, a two wire differential bus, which can connect a single transmitter or source to one or more receivers or sinks. It has two defined speeds, 12.5 kHz and 100kHz. It meets the specifications set by the Aeronautical Radio INC (ARINC) – an organization composed of major airlines and airplane manufacturers, which promotes standardization of aircraft equipment. The ARINC specification defines not only the physical layer and electrical characteristics but the data format of data sent over the bus as well.

To facilitate this, ARINC publishes specifications describing communications busses as well as certain types of avionics systems. One of the more popular busses used in commercial aircraft today is the ARINC-429 bus.
