Powerful 708 Interfaces
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.

Hardware
Models are available with one receive and one transmit channel (1R1T) or with two receive and two transmit channels (2R2T). They support simultaneous operation on all available channels and provide software-selectable word lengths and pre-sync pulses to support custom protocols that deviate from ARINC 708. All include eight avionics level input/output discretes and IRIG time synchronization/generation. Once configured, the USB hardware performs all the protocol processing. It manages the reception, transmission, error checking, time-tagging and buffering of messages—freeing your software to focus on high-level application-specific processing.

Software
Develop software applications with the included BTIDriver API, or use Astronics’ optional CoPilot software. CoPilot provides powerful, easy-to-use interactive tools for databus test, analysis, and simulation.
