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 System CD or can be
downloaded from Multi-Tech’s ftp site.
Upgrade Overview
The upgrade (flash) procedure for the Windows operating system consists of the
following steps:
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 95, 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.
