Data Transfer Units

What should I consider when upgrading my Universal Avionics Data Transfer Unit (DTU)?

The Solid-State Data Transfer Unit (SSDTU) is a direct physical replacement for the DTU or DTU-100. The P2 connector will require replacement if used in the existing installation.  The SSDTU is a different Part Number (P/N) than the DTU or DTU-100, and will require certification approval under FAA Form 337 for installation in the aircraft.
