Appendix B - Updating Your Modem’s Firmware
Introduction
Your modem is controlled by semi-permanent software, called firmware, which is stored in flash memory.
Firmware is nonvolatile; that is, it remains stored in memory when the modem is turned off. However,
either the manufacturer or the user can change the firmware as bugs are fixed or new features are added.
Multi-Tech System’s
Flash Wizard
utility can be used in the Windows operating system to update (flash)
your modem’s firmware.
The
Flash Wizard
utility is available on the MT5634ZPX-V92 CD or can be downloaded from Multi-Tech’s
ftp site.

1. Identify the modem’s model number and firmware version.
2. Identify the current version of the firmware.
3. Download the upgrade (.HEX) file for your modem.
4. Extract the firmware upgrade (.HEX) file.
5. Install The Flash Wizard .
6. Document your stored parameters.
7. Upgrade the modem’s firmware using the .HEX file and the Flash Wizard.
8. Restore your parameters.
Step 1: Identify the Modem Firmware
You must know the model number and firmware version of your Multi-Tech modem to know whether you
should update it.
1. Run your favorite terminal program. If you are using Windows 98, Windows NT, or Windows
2000, you can use HyperTerminal.
2. In the program’s 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. The modem should respond
OK.
3. After the modem responds OK, type ATI and press Enter. Record your results. The model
number and firmware version should appear.
Step 2: Identify the Current Firmware Version
Identify the current version of the firmware available for your modem on 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 Multi-Tech System’s support web page. Follow the
links to the modem firmware page.
2. Locate your modem model number.
3. Compare the firmware version number for your modem as found in

rent version, it does not need to be updated.
