DDC’s DD-42916C1-300 is a PMC (PCI Mezzanine Card) designed specifically to interface with an ARINC 429 data bus.
Available from Allied Data Systems , the card contains both transmitters and receivers and can be used for analysing and simulating data on an ARINC 429 Data Bus.
The card provides 16 independently programmable Rx/Tx channels, with High speed/Low speed operation and engineering unit conversion.
This card is well suited for all types of ground support work (development, manufacturing test, etc), as well as on-board data acquisition.
LRU developers find that these cards provide easy access for simulating and/or testing new systems prior to use with actual flight systems.
Avionics maintenance and validation teams can perform end-item testing in the laboratory and by using portable PCs can continue testing in an aircraft.
The card has an on-board processor operating at 90MHz. The card contains 512Kb of dual-port RAM that can be accessed by both the PC and the card.
This dual-port RAM is used to reliably transfer ARINC 429 data to and from the card.
