Software Upgrades
To perform a software upgrade:
1. Turn off the FLS-2600B.
2. If it is not already done, turn on the computer.
3. On the hard disk of your computer, create a directory named "Test"
(C:\Test).
4. Insert the upgrade diskette into the computer’s floppy disk drive and
copy the *.hex file into the new directory (if necessary, unzip the file).
5. Connect one end of a null modem cable to the FLS-2600B RS-232 serial
port and the other end to an unused communication port on your
computer (ex. COM2).
6. If the software upgrade is performed in Windows 98, you have to
restart your computer in DOS mode before starting the upgrade
program. Otherwise, simply exit to DOS.

From C:\Test directory, type LO0006.exe /c:2 /F:C:\Test\*.hex,
