4. Double-click on the firmware zip file. Extract the files to the Flash Wizard folder. In a default

installation, this is C:\Program Files\Multi-Tech Systems\Flash Wizard\.

Recording Stored Parameters

Before flashing your modem, record the parameters that are currently stored in it, so you can

reprogram it after flashing. After you have recorded them, send the AT&F command to the modem to

clear the stored parameters.

1. Run your favorite terminal program. If you are using Windows 2000+ / XP, you can use

HyperTerminal.

2. In the program’s terminal window, type AT&V and press Enter to list your modem’s current

parameters.

3. Record your parameters by saving the LCDs and sending them to your printer.

4. Type AT&F and press Enter to clear your stored parameters and reset your modem to factory

default.

5. Close the terminal program.

Upgrading the Modem’s Firmware

Before you begin the following procedure, read the README.TXT file extracted from the upgrade

archive file. Note the file name for the boot code (e.g., F35ALOAD.S37) and the file name for the new

firmware (e.g., BKQG300G.HEX).

WARNING: Never install an older version of firmware over a newer version. Doing this WILL DESTROY

THE FLASH PROM! If the flash PROM is destroyed, the modem must be sent in for repair.

1. Run Flash Wizard by double-clicking its icon or by selecting it from the Start menu. The Identifying

Devices dialog box is displayed as Flash Wizard locates and identifies the devices connected to your

system.

Note: If the message ERROR No valid devices detected is displayed, verify that the modem is

turned on and that all cables are correctly and securely attached.

2. Click the modem to be upgraded, and then click Next to proceed.

3. Select the port to be upgraded from the Port list, select the appropriate .HEX file from the Hex File

list, and then click Next to continue.

Note: Do not use FLASHLDR.HEX. This file is used internally by Flash Wizard.

4. The Progress dialog box appears, showing a status bar that indicates the progress of the upgrade.

Caution: Disrupting the program during this stage of the upgrade can cause your modem to

become inoperable. Wait for the Next button to become active before proceeding.

5. When the flash upgrade is complete, the message Programming Complete appears. Click Next to

continue.

6. The Results dialog box appears next. Click Finish to exit Flash Wizard.

Restoring Your Parameters

Your modem has been updated. You can now open your terminal program to reprogram your modem

parameters or to confirm the update by typing ATI3 in the terminal window and pressing Enter.
