Appendix F - Upgrading the Modem

5. If the firmware version number is greater than the firmware version number found in

“Step 1: Identify the Modem Firmware,” your modem has an older firmware version.

Continue with “Step 3: Download the Upgrade File.”

Warning: The first digit of the new firmware must match the first digit of the old

firmware, or the modem may not work properly; e.g., if your current firmware version is

4.16, replace it only with 4.xx firmware, not 6.xx firmware.

Step 3: Download the Upgrade File

1. If you are not already at the MultiMobileUSB firmware page of the Multi-Tech Web site,

follow the procedure in “Step 2: Identify the Current Firmware.”

2. Download the upgrade file for your modem by clicking its name, and save the file in a

temporary folder on your hard disk.

3. In the same section of the Web page, download the Flash Wizard utility for your operating

system by clicking it, and save it in the same folder.

Step 4: Extract the Upgrade Files

1. Install the Flash Wizard utility by double-clicking the file name in Windows Explorer.

2. Extract the upgrade files by double-clicking the file name. The extracted files include a

.HEX file, which contains the upgrade data, and a Readme file.

3. Copy the upgrade .HEX file into the Flash Wizard folder, which, in a default installation, is

at C:\Program Files\MultiTech Systems\Flash Wizard\.

Step 5: Clear Your Stored Parameters

Before you flash your modem, you should 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 the

modem to clear the stored parameters.

1. Run your favorite terminal program. If you are using Windows 95, 98, 2000, or Windows

NT, 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 screens 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.

Step 6: Upgrade 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 new firmware (e.g., BkQg300G.hex).

Warning: Never install an older version of firmware over a newer version. Doing so 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 file name, 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

device is powered on and that all cables are correctly and securely attached.
