4.1 Flash Updating via Internet
The CDM-840 Remote Router uses ‘Flash memory’ technology internally. This makes software
upgrading very simple, and updates can now be sent over satellite, 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 unit over satellite or by simply
connecting the unit to the Ethernet port of the external PC.
•
The firmware update is transferred, via File Transfer Protocol (FTP), from the external PC to
the unit.
