Chapter 4. FLASH UPGRADING
4.1 Introduction
The MBT-5003 uses ‘Flash memory’ technology, and new firmware can be uploaded 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 4-1), via e-mail, or on CD.
The complete upgrading process is as follows:
• New firmware can be downloaded via the Internet to an external PC.
• The upgrade can be performed without opening the MBT-5003 by simply connecting the
unit to the Ethernet port or serial port of the external PC.
• The firmware update is transferred, via File Transfer Protocol (FTP), from the external
PC to the MBT-5003.
