DIGIBUS is a communication bus used in many French military equipments such as MIRAGE 2000 aircrafts, LECLERC battle tank and various French Navy vessels or submarines.

It is similar to MIL STD 1553 (same notion of bus controller, remote terminal, monitor, same transmission speed) but uses separate links for data and commands.

  • PMC-DIGICOOL board is a full function controller : it can, simultaneously, simulate a bus controller, several remote terminals and acquire and time stamp the traffic over the bus.
  • PMC-DIGICOOL-S is a monitor board which captures and time stamp the traffic over the bus.

Both boards can be used in ground test systems as well as in embedded equipments. They conform to PMC mezzanine format and can be used directly on a processor board with PMC slots. One may also use them in PCI, compact PCI or PCIexpress systems with carrier boards.

A full software support including driver, interface libraries and sample programs is provided for Windows XP or 7 and Linux. vxWorks is also supported.

BusView software is an easy-to-use application for Windows. It can simulate a bus controller or several remote terminals. It records and displays the data exchanged on the bus.

BusView software : simulate and display a DIGIBUS installation


Main functions :

  • Traffic description
  • Simulation of a bus controller
  • Message display
  • Interactive message modification
  • Full traffic recording on file
  • Replay of a sequence on display
  • Message filtering





Execution mode :

  • Simulator : the software is active on the bus
