CDS -- GENERAL DESCRIPTION Purpose The common display system (CDS) shows this data to the flight crew: -Attitude -Navigation -Flight mode -Engine and systems data. The CDS also is an interface between some airplane systems. External Interfaces The computer for the CDS is the display electronics unit (DEU). Many avionic and airframe systems have interfaces with the DEUs. These systems send ARINC 429, analog, and discrete data to the DEUs. The DEUs send ARINC 429, analog, and discrete data to these systems. Components These are the components of the common display system: -Two display select panels -One engine display control panel -Two EFIS control panels -Two display source selectors -Two display electronics units (DEUs) -Four coax couplers -Six display units (DUs) that are the same -Two brightness control panels 737-600/700/800/900 TRAINING MANUAL -Two remote light sensors (RLSs). Operation These are the things that sets the data that shows on the displays units: -Display unit status -Display unit location -Selections made on the control panels and modules. These are the formats that show on the display units: -Primary flight display (PFD) -Navigation display (ND) -Engine display. Functional Description Two DEUs collect data from many avionic and airframe systems. Each DEU sends the data out on two coax cables. A coax coupler at the end of each coax cable divides the data signal and sends the data to all six display units. The two DEUs send data to all six display units. The DUs have program pins that identify the DU position. The DU position sets what data the DU shows on its display. DU status data goes from each DU to the DEUs on ARINC 429 data busses. The DEUs also are the interface between some avionic and airframe systems. For example, the DEUs receive BITE data from the electronic engine controller (EEC) and auxiliary power unit (APU). The DEUs send this data 31-62-00
