Appendix B – Upgrading the Firmware

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 MultiModem II 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, click the Flash Wizard utility for your operating system to download 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\Multi-Tech 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 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.

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 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 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 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.
