Appendix B. FLASH UPGRADING

The modem eliminates the need for updating firmware by physically replacing EPROMs.

Instead, the 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.

B.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)

<0/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.

Note: The c: is the drive letter used in this example. Any valid writable drive

letter can be used.
