23) Press the center button to start the bootloader firmware upgrade process. More information and
‘Waiting for download… (you have 30s)’ will be display. The microAeth will wait 30 seconds for the user
to send the firmware data file to the microAeth through the terminal emulator. If a file is not sent to the
microAeth, the instrument will timeout, display 'LOAD BAD' and shut down. If this occurs, the microAeth will
no longer have a valid firmware loaded. Any time the instrument is turned on again, only the bootloader will
start.
24) To send a file to the microAeth through Tera Term. Select the 'File' menu and select 'Send file...'
25) The 'Tera Term: Send file' window will open. Select the firmware '.hex' file.

have a valid firmware loaded. Any time the instrument is turned on again, only the bootloader will start.
29) If the firmware transfer and upgrade are successful, the data transfer will finish, ‘GOOD LOAD’ will be
displayed, self-checks will complete, ‘SUCCESS’ and ‘Shut Down’ will be displayed, and the microAeth will
shut down. Once the screen backlight turns off, the firmware upgrade is complete.
