UPDATING THE FIRMWARE USING XMODEM
Introduction
The ATLAS 550 supports firmware updates via the ETHERNET port using either TFTP from a network
server or the CONTROL IN or CRAFT interfaces using XMODEM. This procedure outlines the steps for a
successful firmware upgrade using the CONTROL IN or CRAFT interfaces and XMODEM software.
Tools and Materials Required
• VT100 terminal or PC with VT100 terminal emulation software
• XMODEM software
To prevent electrical shock, do not install equipment in a wet location or during a
lightning storm
Electronic modules can be damaged by static electrical discharge. Before handling
modules, wear an antistatic discharge wrist strap to prevent damage to electronic
components. Place modules in antistatic packing material when transporting or storing.
When working on modules, always place them on an approved antistatic mat that is
electrically grounded.
