ARINC 429 TO MIL-STD-1553 DATA TRANSLATOR PROTOCOL CONVERTER

ARINC 429 to MIL-STD-1553 Data Translator Protocol Converter

ARINC 429 to MIL-STD-1553 Data Translator Protocol Converter translates data from an ARINC 429 high/low speed data bus to a MIL-STD-1553 data bus.
The 1553 interface on this converter is configured as a single channel, single redundant Bus Controller (BC), but it could equally be configured as a dual redundant Remote Terminal (RT).
Typical uses for this type of converter are to provide an interface between an aircraft’s INS (ARINC 429) and mission equipment on a MIL-STD-1553B Databus.

The interface to the ARINC 429 bus is via high-speed opto-couplers assuring electrical isolation with the
rest of the equipment on this bus.
The interface can be used to acquire aircraft
navigation and attitude data from typically an INS.
The BC is responsible for transmitting the aircraft’s navigation and attitude data in the form
of a MIL-STD-1553 command word, immediately
succeeded by a fixed number of data words.
The typical update rate for the ARINC 429 data
would be 64 Hz.
The BC typically retransmits the data with a fixed frequency of 16 Hz.

A watchdog circuit is incorporated into the design and this is responsible for checking that the transmission of the 1553 continues under all conditions.

The customer must specify the required ARINC 429 labels selected for translation onto the
MIL-STD-1553 databus at the time of ordering. The 1553 data must also be specified - in particular the RT Address, Sub-Address, message type (BT to RT, RT to BC, RT to RT, etc.) and message length.
In addition the customer must also supply data word formats for each of the 16-bit data words contained in the transmitted 1553 message. As the ARINC 429 data can span up to 21-bits of data the translated 1553 data may have to span two 16-bit data words.
Precise information on how each data field is to be translated from the ARINC 429 to the 1553 must also be supplied.
