DATA ACQUISITION SYSTEM - DESCRIPTION AND OPERATION
1.
2.
General
A.
This section gives a general description for the data acquisition system. The only line replaceable
unit (LRU) for the data acquisition system is the Collins DCU-5010 Data Concentrator Unit (DCU).
B.
Refer to Figure 1 for a general view of the data acquisition system.
Description
A.
Data Concentrator Unit (DCU)
(1) The dual-channel DCU is installed in the tailcone, above the baggage compartment, at
approximately TCS 100. It receives analog, discrete, and ARINC 429 bus data from the engines
and the airplane systems. The DCU then sends the data through the ARINC 429 busses to
the circuits and the LRU's as follows:
•
Pilot's and the Copilot's Primary Flight Display (PFD)
•
Pilot's and the Copilot's Multifunction Display (MFD)
•
Integrated Avionics Processing System (IAPS)
•
Aircraft Recording System (AReS) Unit
•
Left and the Right Radio Interface Unit (RIU)
•
Terrain-Avoidance Warning System (TAWS)
•
Flight Data Recorder (FDR)
•
Off-Side (internal) DCU Channel.
(2) The DCU supplies the primary interface between the Collins avionics system and the systems of
the airplane. It examines the input data to supply the visual display of the system cautions and
the warnings to the light crew. It shows this on the light displays and the discrete annunciators
when necessary. The DCU also gives engine data, airplane system data, and synoptic data for
the light displays.
(3) The DCU does the crew alerting system (CAS) logic and concentration of data from many
sensors and system units. The DCU outputs engine and airplane sensor data to the MFD's.
(4) The DCU receives analog and discrete signals from the systems as follows:
Automatic Flight Control System

Hydraulic Indicating
Interior Lighting

On airplanes -000001 thru -000216, the DCU mounted fan is on only when AVIONICS is ON.
The fan operates off of channel A, which receives power when AVIONICS is ON.
