5.1 Firmware Overview
Make sure to operate the DT-4500 with its latest available firmware.
The DT-4500 Series C- or Ku-Band Down Converter is factory-shipped with its
latest version of operating firmware. If you need to update the firmware, you can
apply the update to the DT-4500 without having to remove it from operation.
You may directly acquire the download from Comtech EF Data’s web site
(www.comtechefdata.com), or receive the archive file by e-mail from Comtech EF
Data Product Support.
