Chapter 4. UPDATING FIRMWARE
4.1 Updating Firmware via the Internet
TO ENSURE OPTIMAL PERFORMANCE, IT IS IMPORTANT TO OPERATE THE LBC‐4000
WITH ITS LATEST AVAILABLE FIRMWARE.
The LBC‐4000 L‐Band Up/Down Converter System with Ethernet is factory‐shipped with the
latest version of operating firmware. If you need to update the firmware, you can acquire the
download from the Comtech EF Data Web site (
www.comtechefdata.com ) or from Comtech EF
Data Customer Support during normal business hours via e‐mail or on CD by standard mail
delivery.
The LBC‐4000 Firmware Update process is as follows:
• Perform the update without opening the LBC‐4000 by connecting the Ethernet and the
serial ports of a user‐supplied PC to the LBC‐4000 rear panel ‘10/100 ETHERNET’ port
and the ‘J1 | COM1’ serial port.
• Download the firmware update via the Internet to the user PC.
• Transfer the firmware update files, via File Transfer Protocol (FTP), from the user PC to
the LBC‐4000.
