Appendix C – Upgrading Modem Firmware

Your modem is controlled by semi-permanent firmware, which is stored in flash memory. Multi-Tech's firmware

remains stored in memory when the modem is turned off and can be upgraded as new features are added.

Checking the Modem Firmware Version

Check the current firmware version to determine if an update is needed:

1. Run a terminal program, such as HyperTerminal.

2. In terminal window, type AT&F. Even if you cannot see the AT&F command on your screen, be sure to type it

completely, and then press Enter. If the modem does not respond with OK, repeat the AT&F command.

3. Now type ATI4, press Enter, and record your results. The model number and firmware version should appear

similar to that shown below. In the example below, the firmware version is 1.032d.

Agere OCM v.92 MT9234ZPX-UPCI Internal Data/Fax Modem version 1.02d.

Identifying 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 upgrade it.

1. Go to http://www.multitech.com/setup/product.go and select your model from the Product drop down list.

2. Click Firmware. The firmware zip file name contains the version number. For example, IEQG102E.zip, indicates

version 102E.

3. Compare the version numbers.

● If the firmware version number matches the firmware version number on your modem, your modem does

not need to be upgraded.

● If the current firmware version number is greater than the firmware version on your modem needs to be

upgraded.

Warning: The first digit of the new firmware must match the first digit of the old firmware, or the modem may

not work properly (for example, if your current firmware version is 4.16, replace it only with 4.xx

firmware, not 6.xx firmware).

Upgrading Firmware on Windows

Installing the Flash Wizard Utility

From modem firmware page selected above:

1. If you are not on the page for your modem go to http://www.multitech.com/setup/product.go and select the

model from the Product drop down list.

2. Click Software.

3. Click the Flash Wizard utility link and click Open or Run the file.

4. Click Next to start through the Flash Wizard installation. Note the folder where the Flash Wizard will be

installed; you’ll need to extract the upgrade file to the same location.

5. Click Next and then click Finish.
