Chapter 4. FLASH UPGRADING
4.1 Flash Updating via Internet
Because the CDM-740 Satellite Modem uses integrated ‘Flash memory’ technology, the need for
updating firmware by physically replacing EPROMs is eliminated. This makes software upgrading
very simple, and updates can now be sent via the Internet (Figure 4-1), via E-mail, or on CD.
This chapter outlines the complete upgrading process as follows:
• New firmware can be downloaded via the Internet to an external PC.
• The upgrade can be performed without opening the CDM-740 by simply connecting the unit
to the Ethernet port of a computer.
• The firmware update is transferred, via File Transfer Protocol (FTP), to the CDM-740.
