Figure 3-7 to Figure 3-10 present the HSD-Xi and network mode HSD terminals connection
details.
6. Electrical Description
See Figure 3-7 to Figure 3-10 for installation information.
7. HSD-Xi Terminal System Interfaces
This section briefly describes the external HSD-Xi terminal system interfaces connections to
other systems on the aircraft. For information on interface connections available to aircraft
passengers, see "Installation" on page 3-1.
A. Forward IDs
Forward IDs identify the terminal to the Inmars
at Network.
The 24-bit Forward ID strap pins on the ARINC 600
connector form part of the Inmarsat
Serial Number (ISN). The ISN consists of the type approval number and the Forward ID.
Each Forward ID is associated with Inmarsat Mobile Numbers that a user on the ground
dials to reach the terminal on the aircraft. There is a unique Inmarsat Mobile Number for
each of the service types.
B. Discrete Outputs
The discrete outputs indicate the HSD-Xi terminal status.
