Chapter 4. FLASH UPGRADING
4.1 Flash Updating via Internet
The CDM-Qx/QxL Open Network Satellite Modem eliminates the need for updating firmware by
physically replacing EPROMs. Instead, the CDM-Qx/QxL uses ‘Flash memory’ technology
internally. 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-Qx/QxL by simply connecting the
unit to the USB or serial port of a computer.
• The firmware update is transferred, via File Transfer Protocol (FTP), to the CDM-Qx/QxL.
