SYSTEM DESCRIPTION, INSTALLATION, AND MAINTENANCE MANUAL
MCS--4200/7200 Multi--Channel SATCOM System
B. Electrical Installation
(1) The information necessary to supply the electrical interconnects is shown in
Figure 5-12 thru Figure 5-26. Interconnect diagrams are as follows:
• Figure 5-12. Satellite Data Unit & HSU Interface Diagram
• Figure 5-13. CMC Top--mounted High Gain Antenna Interface Diagram
• Figure 5-14. WH--10 Handset Interface Diagram
• Figure 5-15. HF--SAT Transfer Panel Interface Diagram
• Figure 5-16. Signal Conditioning Unit Interface Diagram
• Figure 5-17. Maintenance Panel Assembly Interface Diagram
• Figure 5-18. HS--720 Interface Diagram
• Figure 5-19. HS--720 Forward ID and Configuration Pins
• Figure 5-20. Tecom Top--Mounted High Gain Antenna Interface Diagram
• Figure 5-21. Mechanically Steered High Gain Antenna Interface Diagram
• Figure 5-22. AMT--50 Mechanically Steered High Gain Antenna Interface Diagram
• Figure 5-23. Dassault Conformal High Gain Antenna Interface Diagram
• Figure 5-24. Ball Conformal High Gain Antenna Interface Diagram
• Figure 5-25. Low Gain Antenna Interface Diagram
• Figure 5-26. Toyocom Top--Mounted High Gain Antenna Interface Diagram.
(2) The applicable configuration pins in the aircraft wiring must be connected to make the
MCS system functional. The SDU receives and sends 30 system configuration
discrete inputs through the configuration pins to properly match the avionics
equipment installed on the aircraft (see Figure 5-12 and Paragraph 4. to identify the
configuration pins).
(3) The SDU receives a 24-bit ICAO address that identifies the aircraft in which the SDU
is installed (Figure 5-12). Continuity is defined as a resistance of 10 ohms or less
between a configuration pin or address pin and the common. Continuity is broken
when the resistance between a configuration pin or address pin and common
measures 100k ohms or greater.
(4) Table 5-6 lists ICAO Block Strapping.
