SYSTEM DESCRIPTION, INSTALLATION, AND MAINTENANCE MANUAL
eNfusion™ HSD-128 High-speed Data Terminal
D. Mechanical Description
This section describes the mechanical characteristics of the HSD and HSD-X
transceivers.
(1) HSD Transceiver
The HSD transceiver is an 8-MCU sized unit with mounting requirements according
to the ARINC 600 specification. The front panel has one, socket D-Type size B (25
contacts) maintenance port connector (under protective cover) for data loading and
monitoring of the unit. Two front-panel LEDs indicate unit status.
The rear connector complies with ARINC 600, shell size 2 and has three inserts: upper,
middle, and bottom. The upper and middle inserts each have one #1 coax contact
and seventy, 22-gauge signal contacts. The bottom insert connector has contact with
only positions 1, 2, 3, 7, 8, and 12. The rear panel has three polarization points.
For detailed wiring information, refer to the interconnection diagrams and contact
assignments for each installation mode presented in
"Installation" on page 3-1 as
noted below:
(2) HSD-X Transceiver
The HSD-X is a 2-MCU sized unit with mounting requirements according to the ARINC
600 specification. The front panel has one, female, micro-D type connector for data
loading and monitoring of the unit. Three front panel LEDs illuminate to indicate unit
functionality as described in detail in
"Test and Fault Isolation" on page 4-1.
