Appendix B - Upgrading the Firmware

Your modem is controlled by firmware, which is stored in flash memory. The firmware remains stored in
memory when the unit is turned off. Occasionally, Multi-Tech releases an update to the firmware to add
features or improve operation. Since the firmware is stored in flash memory, you can upgrade it in a few
minutes by using the following procedures.
Identifying the Modem Firmware
You must know the model number and firmware version of your Multi-Tech modem to know whether or
not you should update it. To check the firmware version:
Run your favorite terminal program. If you are using Windows, you can use HyperTerminal.
1.
In the program's terminal window, type AT&F. Even if you cannot see the AT&F command on your
2.
LCD, be sure to type it completely, and then press Enter. If the modem does not respond with OK,
repeat the AT&F command.
Now type ATI3, press Enter and record your results. The firmware version should appear first in the
3.
response, which should look similar to the following:
ACF3_V1.702a_V90_P21_FSH
Identifying the Current Firmware Version
Identify the current version of the firmware at the Multi-Tech Web site. If your modem already has the
current firmware, there is no need to update it.
Go to http://www.multitech.com/en_US/SUPPORT/Updates/Firmware/.
1.
Select your model from the drop down list.
2.
Look at the firmware version number for your modem.
3.
If the firmware version matches the firmware version on your modem, it does not need to be
●
updated.
If the firmware version is greater than the firmware version on your modem, your modem has
●
an older firmware version and 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.
Downloading the Flash Wizard and Firmware Files
While still on the firmware page for your model,
1.
(http://www.multitech.com/en_US/SUPPORT/Updates/Firmware/) click Software in the left
navigation bar.
Click the Flash Wizard exe file for your operating system.
2.
For the EXE version, Open/Run the exe to install it. Click Next twice and then click Finish to
●
complete the install.
If you download the Mac version, extract the files and install the Flash Wizard.
●
Click Firmware in the left navigation bar to return to the firmware page.
