Specifications of Core429-DEV-KIT

• Processor To Be Evaluated: ProASIC Plus
• Interface Type: RS-232

The parity bit is bit 32 (the MSB). SSM is the Sign/Status
Matrix and is included as bits 30 and 31. Bits 11 to 29
contain the data. Binary Coded Decimal (BCD) and binary
encoding (BNR) are common ARINC data formats. Data
formats can also be mixed. Bits 9 and 10 are Source/
Destination Identifiers (SDI) and indicate for which

Transmission Order
The least significant bit of each byte, except the label, is transmitted first, and the label is transmitted ahead of the
data in each case. The order of the bits transmitted on the ARINC bus is as follows:

receiver the data is intended. Bits 1 to 8 contain a label
(label words) identifying the data type.
Label words are quite specific in ARINC 429. Each aircraft
may be equipped with different electronic equipment
and systems needing interconnection. A large amount of
equipment may be involved, depending on the aircraft.
The ARINC specification identifies the equipment ID, a
series of digital identification numbers. Examples of
equipment are Flight Management Computers, Inertial
Reference Systems, Fuel Tanks, Tire Pressure Monitoring
Systems, and GPS Sensors.
