uMACC - Converter

Excalibur Systems

The uMACC is a wholly contained Communications Converter (data converter - protocol converter or translator). Its small size makes it a complete solution for developing & testing both in the lab and in the field.

The uMACC can carry up to 4 modules. Each module can be one of the following protocols: 

Please see multi protocol 8000 modules for additional information on protocols that can be used on the uMACC.

The processor may be programmed to convert data in real time from any format to any other format. The uMACC 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 communications incompatibilities.

Before Ordering: 

The uMACC 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 uMACC 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 uMACC .

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 uMACC 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 uMACC thereby solving project specific issues at lower cost and lower risk that would otherwise be possible. This may involve customization of the uMACC 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.
