Step 3: Download the Upgrade File
1.
If you are not already at the MultiModemZDX 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 .S37 file into the Flash Wizard folder, which, in a default installation, is at
C:\Program
Files\MultiTech Systems\Flash Wizard\.
Step 5: 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., 2MBPFL1 1 .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 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.

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

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.

The
Progress
dialog box appears, showing a status bar that indicates the progress of the upgrade.
Caution:
Any disruption of 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.

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

The
