Comtech EF Data CDM-700 - Manual (Page 139)

Chapter 9. FLASH UPGRADING
9.1 Introduction
The CDM-700 eliminates the need for updating firmware by physically replacing EPROMs. Instead,
the CDM-700 uses ‘Flash memory’ technology internally. This makes software upgrading very
simple, and updates can now be sent via the Internet (Figure 9-1), 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-700 by simply connecting the unit
to the serial port of a computer.
• The firmware update is transferred, via File Transfer Protocol (FTP), to the CDM-700.
