Chapter 3. FLASH UPGRADING
3.1 Introduction
The Troposcatter Solid State Power Amplifier (referred to
hereafter as ‘the TRP500’) uses ‘Flash memory’ technology,
and new firmware can be uploaded to either unit from an
external Microsoft Windows
® -compatible computer. This
makes software upgrading very simple, and upgrade files
containing the current version of firmware are available over
the Internet (Figure 3-1); via e-mail; or on CD.
This chapter outlines the complete upgrading process as
follows:
• New firmware can be downloaded via the Internet to
an external PC.
• The upgrade is accessible to the TRP500 by simply
connecting the unit to the serial port of the external
PC.
• The firmware upgrade is automatically transferred,
via File Transfer Protocol (FTP), to the TRP500
using CEFD’s CReflash utility application.
