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. Excalibur’s MACC II represents a third option. A proven, low risk, low cost, off the shelf product that translates between different communications specifications. The MACC II can solve your communications problems without R&D costs and without schedule risks while still providing you with the flexibility to customize the system to your specific needs. The MACC II is a wholly contained Miniature Airborne Communications Converter (data converter - protocol converter or translator). The MACC II can carry up to 4 modules. Each module can be one of the following protocols: 1 dual redundant MIL-STD-1553/1760 interface 1 H009 channel 5 MMSI channels 5 ARINC-429 channels 2 ARINC-708 channels 2 ARINC-717 channels 5 ARINC-825 (canbus) channels 2 Serial channels (RS-232/422/485, NMEA 0183) Ethernet (10/100/Gigabit) 10 Discrete I/O signals Analog to Digital / Digital to Analog Please see multi protocol 8000 modules for additional information on protocols that can be used on the MACC II. The processor may be programmed to convert data in real time from any format to any other format. The MACC is programmed directly on the hardware - i.e. with no operating system - enabling it to achieve optimum latencies. Its small size, weight, low power requirements and integrated heatsink make it an excellent candidate for solving airborne communications incompatibilities. Before Ordering: The MACC is a table driven Avionics translator that enables devices supporting different communications specifications (e.g. Ethernet, Serial, ARINC 429, CAN Bus, Mil-1553, Discretes etc.) to talk to each other. The MACC is designed to work as COTS equipment requiring only that the user populate the translation tables and download them using the accompanying software to the MACC . Since Excalibur engineers have the experience in dozens of projects we have found that our customer’s projects can be implemented much faster and with lower risk if we fill in the tables for them. We provide this service free of charge. The tables are then provided to the customer who may then edit them to change, add to, or refine as required by the project. We also have experience with projects in which simple translation is insufficient and the MACC is tasked with initializing equipment on its own – without input data to guide it, or where special timing requirements or state machines need to be enforced not directly related to inputs. We often can implement these requirements into the MACC thereby solving project specific issues at lower cost and lower risk that would otherwise be possible. This may involve customization of the MACC and may incur NRE costs. In order to implement these tables and to determine if any special processing is required we ask you to send us a written spec of your requirement.
