SYSTEM DESCRIPTION, INSTALLATION, AND MAINTENANCE MANUAL
MCS--4200/7200 Multi--Channel SATCOM System

HSD Channel ISN
a
Following the display of the ICAO aircraft address, the Inmarsat Serial
Number (ISN) for each installed HSD channel is displayed as shown
below:
ISNX: YYYYYY ZZZZZZ
Where "X" is a decimal number from 1 to 4 used to distinguish multiple
ISNs, and where "YYYYYY" represents the Type Approval ID and
"ZZZZZZ" the Forward ID. The ISNs for each installed HSD channel are
displayed on a separate line. If the ISN for an installed HSD channel is
not available, dashes are displayed in place of the Type Approval ID
and the Forward ID.

ORT Identification
a
Following the display of the ISNs, if one or more HSD channels are
installed, or after the ICAO, if no HSD channels are installed, the user
ORT identification is displayed as specified:
• ORT ID--XXXXXXXXXXXXX (first line)
• XXXXXXXXXXX--MODIFIED (second line, after another activation of
the MANUAL SCROLL button).
b
Where XXXXXXXXXXXXXXXXXXXXXXXX represents the 24-character
description contained in the user ORT description field. The user ORT
description field is used to annotate a particular set of ORT items to
identify one from another (e.g., NORTH PACIFIC ROUTE, SOUTH
ATLANTIC ROUTE, 747--400 ASIAN ROUTE, 777 ASIAN ROUTE).
Alternatively, this item could contain a software identification (e.g., a
software part number for the user ORT as a released entity).
c
The MODIFIED flag is only displayed if the state of the user ORT
modified flag indicates any item in the user ORT has been modified
since the user ORT was created. When any user ORT item is modified
by the SDU software, either directly or indirectly, the user ORT modified
flag is set to MODIFIED. If the state of the user ORT modified flag is
unmodified, the MODIFIED flag is not displayed. The state of the user
ORT modified flag is never set to unmodified by the SDU software.
d
The next two pushes of the MANUAL SCROLL button present the same
information for the Secured ORT partition.

SDU Temperature
a
Following the display of the ORT Identification, the SDU temperature is
displayed as shown below:
