Appendix B – Upgrading the Modem’s Firmware 

Multi-Tech Systems, Inc. MT5634ZBA-Series User Guide (S000286G)                

If you are not already at the MultiModem ZBA Firmware page of the Multi-Tech Web site, follow the 
procedure in “Step 2: Identify the Current Firmware.” 

Download the upgrade file for your modem by clicking its name, and save the file in a temporary folder on 
your hard disk. 

In the same section of the Web page, click the Flash Wizard utility for your operating system to download 
it, and save it in the same folder. 

Install the Flash Wizard utility by double-clicking the file name in Windows Explorer.  

Extract the upgrade files by double-clicking the file name. The extracted files include a .HEX file, which 
contains the upgrade data, and a Readme file.  

Copy the upgrade .HEX file into the Flash Wizard folder, which, in a default installation, is at C:\Program 
Files\MultiTech Systems\Flash Wizard\. 

Before you flash your modem, you should record the parameters that are currently stored in it, so you can reprogram it 
after flashing. After you have recorded them, send the AT&W1Z command to the modem to clear the stored parameters.  

Run your favorite terminal program. If you are using Windows 95 or above, you can use Windows 
HyperTerminal.  

In the program’s terminal window, type AT&V and press E

NTER 

to list your modem’s current parameters. 

Record your parameters by saving the screens and sending them to your printer. 

Type AT&W1Z and press E

NTER 

to clear your stored parameters and reset your modem to factory 

default. 

Close the terminal program. 

Before you begin the following procedure, read the README.TXT file extracted from the upgrade archive file. Note the 
file name for the new firmware (example: ARQG125A.HEX). 

WARNING: Never install an older version of firmware over a newer version. Doing this WILL DESTROY THE FLASH 
PROM! If the flash PROM is destroyed, the modem must be sent in for repair. 

 

Run Flash Wizard by double-clicking its icon or file name, or by selecting it from the Start menu. The 
Identifying Devices dialog box is displayed as Flash Wizard locates and identifies the devices 
connected to your system. 

 If the message ERROR: No valid devices detected is displayed, verify that the modem is turned on 

and that all cables are correctly and securely attached. 

Click the modem to be upgraded, and then click Next to proceed. 

Select the port to be upgraded from the Port list, select the appropriate .HEX file from the Hex File list, 
and then click Next to continue. 

 Do not use FLASHLDR.HEX. This file is used internally by Flash Wizard. 

The Progress dialog box appears, showing a status bar that indicates the progress of the upgrade. 

Caution: Any disruption of the program during this stage of the upgrade can cause your modem to 
become inoperable. Wait for the Next button to become active before proceeding.

 

When the flash upgrade is complete, the message Programming Complete appears. Click Next to 
continue. 

The Results dialog box appears next. Click Finish to exit Flash Wizard. 

Your modem has been updated. You can now open your terminal program to reprogram your modem parameters or to 
confirm the update by typing ATI in the terminal window and pressing E

NTER
