SYSTEM DESCRIPTION, INSTALLATION, AND MAINTENANCE MANUAL
eNfusion™ HSD-128 High-speed Data Terminal
7. Mechanical Installation
This section describes the mechanical installation requirements for the HSD and HSD-X units.
The outline and installation drawings for both transceivers are provided at the end of this
section.
A. General
This section contains the information required to plan the physical placement of the HSD
and HSD-X (Multi-Channel configurations only) transceivers.
The HSD Transceiver Outline and Illustration Drawing (Sheet 1 and 2) illustrates the
physical and mechanical specifications of the HSD transceiver. The HSD-X Transceiver
Outline and Illustration Drawing (Sheet 1 and 2) illustrates the physical and mechanical
specifications of the HSD-X transceiver.
In typical aircraft installations, the HSD assembly fits into standard ARINC, 8-MCU
mounting trays. HSD-X units fit into standard, 2-MCU mounting trays. Specialized trays,
that meet the requirements for installations of both the HSD and HSD-X units on
Helicopters, are also available from EMS SATCOM.
All HSD ARINC installation trays are included in the HSD and HSD-X Installation Kits that
are available from EMS Technologies Ltd. Section
Installation Kits describes the HSD and
HSD-X Installation Kits available from EMS SATCOM.
B. Physical Placement
When selecting a placement location for the HSD, and if applicable, HSD-X mounting
trays, allow for adequate spacing for the installation of the HSD assembly while providing
reasonable access for servicing. Leave a minimum gap of 0.5 inches between LRUs.
In Multi-Channel configurations, after wiring the tray(s) for HSD-X units, populate the trays
in order, starting from the first-in-line tray that is directly connected to the HSD-128
transceiver. The second HSD-X tray is connected to the first HSD-X tray as shown in
Figure 3–1. HSD-X trays are strapped to index the HSD-X units to read the appropriate
ARINC messages on the crosstalk bus (communications bus).
If an HSD-X must be removed for service, the Multi-Channel HSD system will still function,
but the remaining HSD-X units must be moved so that no empty trays are in the middle
of the series or chain. Refer to
"Maintenance and Repair" on page 5-1 for more information.
