The Modular Avionics Controller (MAC) is
GE Intelligent Platforms’ new family of intel-
ligent, high performance 6U VME and C-size 
VXI interface solutions for ARINC 429, serial 
communications and other avionics proto-
cols. As an evolutionary follow-on product 
from GE’s successful VME/VXI-AIC prod-
uct line, the MAC family provides a single 
integrated interface to multiple avionics 
protocols on VMEbus or VXIbus platforms. 

Software
An integrated Application Programming 
Interface (API) is provided for high-level 
access to all MAC-based protocol functions. 
The efficient and easy-to-use MAC-API 
provides high performance access to all 
protocol, control and data functions. A com-
prehensive transition library is also provided 
to seamlessly migrate applications from the 
AIC to the MAC. API support for VxWorks, 
Microsoft Windows 7, Vista, XP and 2000 
is provided for PC-based hosts across the 
GE Intelligent Platforms 810 and National 
Instruments PCI-MXI-2 interface. Linux sup-
port is provided with select GE Intelligent 
Platforms x86-based VME SBCs. High level 
ARINC 429 support is optionally available 
for LabVIEW. For VME and VXI hosts, the API 
is also supplied in source code.

Hardware Architecture
Architecturally, the MAC has two PMC slots 
which can be populated with one or two 
powerful PMC Modules. All user I/O is via 
front panel connectors. Transition cabling 
to 68-pin SCSI III connectors are provided 
with every module.

ARINC 429 product configurations have 
a minimum of 2 receive and 2 transmit 
channels, up to a maximum configuration 
of 48 receive and 16 transmit channels 
or 32 receivers and 32 transmitters, front 
I/O on a single board populated with two 
PMC modules. Data rates, parity, filtering, 
message scheduling, error injection, self-
test operation and protocol features are 
controlled on-board. All ARINC 429 channels 
operate independently and simultaneously 
at full data throughput.

In addition to ARINC 429, MAC configuration 
options offer concurrent, integrated 
support for numerous other 2-wire ARINC 
interfaces including ARINC 419, 453, 571, 
573, 575, 582, 585, 708 and 717. Serial 
interfaces, including RS-232 and RS-422 are 
also supported.
