Upgrading the Embedded Software
5. If the software upgrade is performed in Windows 98, you must restart
your computer in DOS mode before launching the upgrade program. In
other cases, simply exit to DOS.
6. Go to the “C:\Test” folder and launch the upgrade program by typing
the following line (spaces are required between parameters):
Lo0006.exe /C:2 /F:c:\test\filename.hex /S:19200
Parameters can be decoded as follows:
³
/C: serial port number (COM2 in the above example)
³
/F: file to copy on your unit (replace “filename” with the actual
name of the .hex file on your hard disk)
³
/S: computer-to-unit transfer speed (if “19200” does not work, try
“56700”)
7. When the Waiting for device handshake message appears, turn on
the Optical Power Meter.
The unit display remains off, the unit beeps once and the upgrade
program starts automatically. A progress bar on the computer screen
indicates the upgrade status. Once the software upgrade is complete,
the Reboot device for self-test message appears.
