Study Notes
- DATAC is a technology for a single global data bus developed by Boeing.
- It uses a single twisted pair of wires to carry information between components of an aircraft system.
- Each component's data is coded and broadcasted in a synchronized order to prevent jumbling.
- DATAC allowed a greater number of components to be integrated into aircraft systems and reduced maintenance needs.
- DATAC was installed and tested on a NASA 737 before being incorporated into Boeing's B777.
- ARINC used DATAC as the basis for a new industry data bus standard called ARINC 629.
- ARINC 629 is a bidirectional, distributed control bus that can support up to 120 users at a transmission rate of 2 Mbps.
- Terminals listen to the bus and wait for a quiet period before transmitting, and only one terminal can transmit at a time.
- The ARINC 629 terminal controller and Serial Interface Module (SIM) are installed on a circuit board within each Line Replacement Unit (LRU).
- The SIM interfaces with the stub cable via a connector on the LRU, which is then coupled to the global data bus via a current mode coupler.
