Introduction

Your modem is controlled by semi-permanent software (firmware) that is stored in flash memory. Firmware is nonvolatile; 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.

1.Identify the model number and firmware version of your MT4X56USB.

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 .HEX file and the appropriate flash upgrade program from the downloaded file.

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 MT4X56USB Firmware

You must know the model number and firmware version of your Multi-Tech MT4X56USB to know whether you should update it.

1.Run your favorite terminal program. If you are using Windows 95/98, Windows NT 4.0, 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.

3.Now type ATI and record your results. The model number and firmware version should be:

LT V.90 1.0 MT4X56USB Serial Data/Fax/Voice modem Version 4.07a

Step 2: Identify the Current Firmware Version

Identify the current version of the firmware at the Multi-Tech Web site. If your MT4X56USB already has the current firmware, there is no need to update it.

Multi-Tech Web Site

1.Using your favorite Web browser, go to http://www.multitech.com/support/firmware.htm.

2.Scroll down to the table with your MT4X56USB model number (non-USA firmware must be obtained directly from the FTP site).

3.Look at the Current Revision number for your MT4X56USB.

4.If the Current Revision number matches the firmware version number found in “Step 1: Identify the MT4X56USB Firmware,” your MT4X56USB has the current firmware and does not need to be updated.
