Appendix B – Upgrading the Firmware
Appendix B - Upgrading the
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, it
can be changed by either the manufacturer or the user as bugs are fixed or new features are added.
Since the firmware in your modem is stored in flash memory, you can upgrade it yourself in a few minutes
by using the following procedures.
Upgrade Overview
The upgrade procedure consists of the following steps, which are described in greater detail in the following
sections.
1. Identify the model number and firmware version of your modem.
2. 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.
3. Download the upgrade file for your modem.
4. Extract the firmware .HEX file and the appropriate flash upgrade program from the file you
downloaded.
5. Document and clear your stored parameters.
6. Upgrade the modem’s firmware using the .HEX file and the flash upgrade program.
7. 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 or not you should update it.
1. Run your favorite terminal program. If you are using Windows, 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 LCD, 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 ATI3 , press Enter and record your results. The firmware version should appear
first in the response, which should look similar to the following:
ACF3_V1.702a_V90_P21_FSH
Step 2 - Identify 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.
1. Using your favorite Web browser, go to http://www.multitech.com/support/MultiModem
II/firmware.asp .
2. Scroll down the table 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.
