DD-42916X SERIES

ARINC 429 VXI INTERFACE

MODULES

DESCRIPTION

FEATURES

The DD-42916X Series modules, avail-

able in B or C size, provide a high-per-

formance communications link between

a VXI host and an ARINC 429 Data

Bus. This series of modules is factory

configured as either register- or mes-

sage-based devices.

depots for implementing margin testing to

detect "phantom" errors and failures.

• Eight Programmable Parametric

Channels: Receive or Transmit;

High, Low, and Variable Speed;

Variable Voltage; Bit Gap; and

Word Size

The modules support eight configurable

parametric channels that can be set as

either receivers or transmitters. When

acting as transmitters, these channels

can output signals from 0 to 12 Volts.

Transmitters or receivers can be config-

ured for variable word sizes (2 - 32 bits),

appropriate parity (EVEN/ODD/NONE),

variable frequency (5 KHz - 120 KHz),

and variable bit gap.

• Eight Additional Low-Speed

Receivers

The module architecture is based on a

multiprocessor design that provides reli-

able, high-integrity ARINC 429 recep-

tion and transmission. Modules are

designed for high-performance applica-

tions, capable of off-loading tasks from

the host computer that could not previ-

ously be performed by a single interface

module.

• On-Board Engineering Unit

Conversion

• 256 Kilobytes-Dual Port RAM for

Real-Time Data

In addition to the eight configurable

channels, the modules also provide eight

low-speed receiver channels, for a total

of up to 16 independent ARINC 429 chan-

nels. The modules can filter received data

and schedule transmitted data as deter-

mined by the host computer. All of the

DD-42916X series modules have a float-

ing-point coprocessor used to convert

data to and from engineering units. This

allows the host to communicate data to

the module in engineering unit format.

• Available in B or C Size

• RS232/RS422 Port

The modules conform with the Mark 33

Digital Information Transfer System 429-

14 specifications. They are capable of

parametric testing that handles communi-

cations which deviate from the standard

specification. This is useful during the test

and validation phases of Line Replaceable

Unit (LRU) development and at repair
