Chapter 4. FLASH UPGRADING

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 t

he 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.
