SYSTEM DESCRIPTION, INSTALLATION, AND MAINTENANCE MANUAL
eNfusion™ HSD-128 High-speed Data Terminal
Note: All connections, except power and RF, are HSD specific. Refer to “other
SATCOM” and antenna manufacturers’ installation documentation for
interconnection wiring details.
(a) Maintenance Port Interface – Combined/Selective
The HSD transceiver has an RS-232 Maintenance Port interface that provides
access to a maintenance utility program for data loading, system monitoring, and
testing purposes.
Access to the HSD Maintenance Utility Program is achieved by connecting an
RS-232, VT-100 terminal (PC or Laptop operating a terminal emulation program)
to the RS-232 Maintenance Port.
The HSD Maintenance port is available at the front of the HSD and at the rear
ARINC 600 connector. Connection on the front of the HSD is accessible via a
DB25S connector for local maintenance of the unit. Remote access is provided
for cases where local access is unavailable. For remote access, install an
accessible DB9S connector in the cabin area.
Note: The front panel and remote connections to the maintenance port cannot
be used simultaneously.
Refer to "Test and Fault Isolation" on page 4-1 for information on how to connect
and use the maintenance port—including equipment requirements, connection
and cabling requirements, software loading instructions, and configuration
details.
(b) Antenna Subsystem RF Interface – Combined/Selective
Several external RF parameters (such as cable losses and antenna gain), that
must be delimited to ensure proper operation, dictate the HSD performance
requirements.
Table 3–13 defines these parameters and their expected values.
(c) WOW Pin Wiring – Combined/Selective
This section describes the requirements for WOW pin wiring.
• Combined Mode Installations
In Combined Mode installations, WOW1, WOW2, and WOW Program Select
are reserved for future use.
