USB 708 Avionics Interface for Weather Radar

The USB 708 family of pocket-sized USB adapters enable computers to interface with ARINC 708 and similar weather radar display databuses. These rugged USB 2.0 peripherals feature extensive functionality for testing and simulating weather radar systems, CDUs (Control-Display Units), and T-R (Transmit-Receive) units. They are used for monitoring, generating, recording, and playing back data. The ARINC 708 display databus is sometimes referred to as ARINC 453.


These versatile interfaces are suitable for a wide range of applications in the lab and in the field, and are compatible with virtually all modern PC laptop, desktop, and tablet computers. They support maximum data throughput on all 708 channels and have a large 32 MB built-in memory. All power necessary for operation is provided via the single USB port. Plug and Play and Hot Swap features make them easy to install and move between computers.
