SBC hosts
The Modular Avionics Controller
(RMAC/MAC2) is GE Intelligent Platforms’ new
family of intelligent, high performance 6U
VME and C-size VXI interface solutions for
ARINC 429, serial communications and other
avionics protocols. As an evolutionary follow-
on product from GE’s successful VME/VXI-AIC
product line, the RMAC/MAC2 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 RMAC/MAC2-based protocol
functions. The efficient and easy-to-use
MAC-API provides high performance access
to all protocol, control and data functions. A
comprehensive transition library is also
provided to seamlessly migrate applications
from the AIC to the RMAC. 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 RMAC/MAC2 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, RMAC/MAC2
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.
