LBC-4000 L-Band Up/Down Converter System
Revision 6
CEFD provides its archive download files in two compressed formats – *.exe (self-extracting) and
*.zip (compressed):
The self-extracting *.exe file does not require use of a third-party utility program.
Some firewalls do not allow the download of self-extracting *.exe files. You must instead
download the *.zip file, and extract the firmware files from the download with a user-supplied
third-party file archiver and compression utility program such as PKZIP for Windows, WinZip,
ZipCentral, etc. (PKZIP for DOS is not supported due to file naming conventions). CEFD does not
provide this utility program.
For detailed information on handling archived files, read your utility program's Help
documentation.
