Appendix E. FLASH UPGRADING
The CDM-570/570L eliminates the need for updating firmware by physically replacing
EPROMs. Instead, the CDM-570/570L modem uses ‘flash memory’ technology
internally, and new firmware can be uploaded to the unit from an external PC, as follows:
Go to: www.comtechefdata.com
Click on: downloads
Click on: flash upgrades
This makes software upgrading very simple, and updates can now be sent via the Internet,
E-mail, or on disk. The upgrade can be performed without opening the unit, by simply
connecting the modem to the USB or Ethernet port of a computer.
E.1 Ethernet FTP Upload Procedure
1. Identify the reflashable product, firmware number, and version for download.
The current base modem M&C version can be viewed at the top level menu of the
front panel display (press “CLR” button several times to view). Also, you can find
the firmware information within the <Util > <Firmware > <Info> <Image#1,
Image#2 > menu tree.
Using serial remote control, you can query the firmware revision levels with the
<0/SWR? Command. (Abbreviated)
Or
<)/FRW? Command (Detailed)
2. Create a temporary directory (folder) on your PC.
Windows: Select File > New > Folder > and rename the New Folder to "temp" or
another convenient and unused name. Assuming "temp" works, you should now
have a "c:\temp" folder created.
