VN0601

Interface for ARINC 429

The VN0601 is a powerful interface for ARINC 429 bus systems.
It supports test and analysis tasks in avionics development and additionally enables acquisition of further measurement signals via integrated analog and digital IO.

Highlights

Multi‑channel ARINC 429 access: Four ARINC 429 TX and four ARINC 429 RX channels support high‑speed and low‑speed communication. 
Precise time base: High‑resolution time stamps and synchronization with other devices and bus systems enable accurate timing analysis. 
Integrated IO acquisition: Analog and digital inputs and outputs allow additional signal acquisition and control. 

Open and flexible test architecture: The reloadable FPGA hardware architecture and the open XL Driver Library enable integration of custom and third‑party applications.
Rugged design: Electrically isolated connections and a very rugged housing support operation in demanding environments.

Functions

Variable channel‑specific settings
