TTC Mn429-2000 Miniature Network ARINC 429 Interface Unit

The ARINC 429 data bus supplies data from a wide variety of electrical sub-systems to an onboard flight computer. The Mn429-2000 is a miniature networked encoding unit that timestamps the incoming ARINC 429 data, processes and delivers packetized data to designated nodes on an Ethernet network.

The Mn429-2000 stack consists of a unique ARINC 429 bus interface module (MBIM-429B-1), an IEEE 1588 time, and Ethernet interface module that also functions as an overhead card (MARC-500-1), and supporting processor, power supply, and structural components.

Each ARINC 429 interface module receives wordstrings from up to four standard avionics ARINC 429 serial digital data buses, providing automatic and seamless detection and switching between high speed (100 Kb/sec) and low speed (12 Kb/sec) receive data rates. Data words are timestamped as they arrive, buffered on the module, and processed for transmission to the network fabric.

The Mn429-2000 can accommodate up to eight ARINC 429 interface modules, receiving up to 32 data channels. A 30-watt miniature power supply module is available to accommodate additional power requirements for extended stacks.

 

Aerospace Instrumentation Brochure

Modern aerospace instrumentation systems can be highly complex, and it can be difficult to know how to meet program needs. It’s not unusual for requirements to change during a campaign and cause significant delays, and data must be captured reliably no matter what – otherwise expensive additional flights will be needed or months of program data could be lost. Read our brochure to learn how you can reduce your risk with commercial off-the-shelf (COTS) solutions.
