SYSTEM DESCRIPTION, INSTALLATION, AND MAINTENANCE MANUAL
eNfusion™ HSD-128 High-speed Data Terminal
• An RS-232 cable (Asynchronous Serial)
• An activated account with an Inmarsat Service Provider that supports MPDS
services
• A computer with an available COM port
• Dial-up Networking capabilities
When operating MPDS over the RS-232 port, no external connecting devices
are required. The channel card in the HSD acts as a “modem” and responds to
modem “AT” commands.
In order to make an MPDS over RS-232 connection, you need to select a
standard modem on your computer to direct the data traffic to the PC COM port
connected to the RS-232 MPDS port on the HSD.
(b) Using the Ethernet Interface
HSD transceivers with a Data I/O Type 2 Card (PNs 1110-A-0150, 1110-A-0160
and HSD transceivers with service bulletin 1110-SB-0004 accomplished) and all
HSD-X transceiver extensions support the Ethernet interface.
Connections using MPDS over the HSD Ethernet port require the following:
• A Point-to-Point Protocol over Ethernet (PPPoE) driver installed—a PPPoE
driver is the protocol most commonly used by Digital Subscriber Line (DSL)
devices; it establishes the connection of the session and the exchanges of
PPP frames over Ethernet.
• An activated account with an Inmarsat Service Provider that supports MPDS
services
• A computer with an Ethernet port
• Dial-up Networking capabilities/Web browser
• Optional devices (e.g. router) must be PPPoE compatible
(c) Optimizing the System for MPDS
To optimize your system for MPDS:
• Reduce the amount of unnecessary traffic. Ensure that the router
configuration disables unnecessary Local Area Network (LAN) messages.
• Increase the window size in TCP/IP.
• Use DNS caching and Web caching. When using DNS and Web caching,
the server only retrieves from the Internet IP addresses and Web pages not
stored in the server cache.
Note: DNS caching and Web caching is effective when using a LAN
configuration on the aircraft. For stand-alone computers, use a
personal Web browser cache.
To optimize your e-mail client when using MPDS:
• Compress attachments (zip files)
• Under Tools, in the Options of your e-mail client (e.g. Outlook®, Eudora®)
customize the settings for MPDS based on the recommendations below:
