Flash Updates
Appendix C provides information on updating DPI host or peripheral
product firmware.
C.1 Preparing for a Flash Update
Please take the following precautions to ensure a successful flash
update:
• Obtain the new firmware version from Reliance Electric. Save it to
the hard drive of the computer. Do not attempt to perform a flash
from a floppy disk or a network.
• Read all instructions supplied with the new firmware file.
• Use a computer running terminal emulation software that
supports Xmodem transfers (e.g., HyperTerminal).
• Record parameter values in the device that will be flashed.
Updates may reset parameters to their default settings.
• Ensure that the DPI host product (SP600 AC drive) is stopped.
• Close all programs except the terminal emulation program that
you are using to flash the serial converter.
• Disable the screen saver and antivirus programs so that they do
not start during the flash process.
• If you are using a laptop computer, turn off the FIFO buffers in
HyperTerminal. In HyperTerminal, select File > Properties to
display the Properties dialog box. Click Configure, and then click
Advanced. Ensure that a check mark does not appear next to
Use FIFO buffers.
• Verify that Reserved (16) is set to “Auto” (default).
