Step 2: Identify the Current Firmware Version

Identify the current version of your modem's firmware at the Multi-Tech Web site. If your modem
already has the current firmware, there is no need to update it.
1. Using your favorite Web browser, go to
PX/firmware.asp.
2. Scroll down to your modem model number.
3. Look at the firmware version number for your modem.
4. If the firmware version number matches the firmware version number found in "Step 1: Identify
the Modem Firmware," your modem has the current firmware version, and does not need to be
updated.
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."

Step 3: Download the Upgrade File
1. If you are not already at the
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 by clicking it, and save it
in the same folder. Alternately, install the Flash wizard from the MultiModemZPX compact disc.

Step 4: Extract the Upgrade Files

1. Install the Flash Wizard utility by double-clicking the Flash Wizard 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: Document and Clear Your Stored Paramenters

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&W1Z command to the the
modem to clear the stored parameters.
1. Run your favorite terminal program.
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.
