Chapter 4. FLASH UPGRADING
4.1 Overview
This chapter provides procedural information for upgrading the firmware for the Comtech EF
Data PCB-4300 1:2 Phase Combiner. This chapter assumes that the user has familiarity with
Microsoft Windows-based operating systems.
4.2 Flash Updating via Internet
The PCB-4300 uses ‘Flash memory’ technology internally; this makes firmware upgrading very
simple, and updates can now be sent via the Internet (Figure 4-1), via E-mail, or on CD. The
complete upgrading process is summarized as follows:
• New firmware update for upgrading the PCB-4300 is transferred to a user provided PC
intended for Monitor and Control (M&C) of the PCB-4300 system.
• By simply connecting the PCB-4300 to an available serial port on the user-provided PC,
the upgrade can then be performed without opening the PCB-4300.
• Once the firmware update is extracted from the transferred archive file, the upgrade
process is executed via use of a utility program, FLSHCSAT.exe.
