SECTION 5
ELECTRICAL INSTALLATION
1. Overview
A. General
(1) This section supplies electrical installation procedures, power distribution, and
interconnect diagrams for each component of the MCS system.
2. Equipment and Materials
A. General
(1) None.
3. Electrical Installation Procedure
A. Connector Layout and Contact Arrangement
(1) Each front panel connector of the SDU, HSU, and HPA complies with ARINC
characteristic 615, and is used to interface the LRU with an ARINC 615 portable data
loader for software uploads. Pin callouts are specified in Table 5-1. See the
MECHANICAL INSTALLATION section for specifics regarding connector part
numbers for the ARINC 615 connector for each LRU and the corresponding mating
connector.
(2) Table 5-2 lists the pin arrangements for the RJ--45 jack for the Ethernet Port 1. When
a user terminal is connected to this jack, the rear connectors are disconnected so
only the Ethernet Port 1 communications are available from this interface.
(3) The rear connectors of the SDU, HPA, RFUIA, and HSU comply with ARINC
characteristic 600 as specified in Table 5-3. The ARINC 600 connector layouts and
contact arrangement for the various connector plugs for each LRU of the MCS
system are shown in Figure 5-1 thru Figure 5-11.
(4) Table 5-4 and Table 5-5 list the contact arrangements for the top and middle inserts
for the SDU ARINC 600 connector. Table 5-6 lists the ICAO Block Strapping.

(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.
