Chapter 5 – Upgrading Firmware Your device is controlled by semi‐permanent firmware, which is stored in flash memory. The firmware stays in memory when the modem is turned off. It can be updated when new features are added. Since the firmware in your unit is stored in flash memory, you can upgrade the firmware in a few minutes. Determining if You Need to Upgrade the Firmware 1. Use a terminal emulation program to login to the device. The firmware version displays in the Introduction Menu.
Chapter 5 – Firmware Upgrade Identifying the COM port 1. Go to Start I Control Panel and then Open Device Manager. 2. Verify the COM port that is connected to the MT200A2W unit. In this example, it is MosChip PCI Serial Port (COM18). 3. Close the device manager. Upgrading Firmware Note the filename for the new firmware (example: KKQG_1_0_13.hex). Warning: Never install an older version of firmware over a newer version.
Chapter 5 – Firmware Upgrade 3. Close the terminal program. 4. Double‐click the Flash Wizard icon or filename to run Flash Wizard. The Identifying Devices window displays as the Flash Wizard locates and identifies the devices connected to your system. Note: If the message ERROR: No valid devices detected displays, verify that the MultiConnect is turned on, that all cables are correctly and securely attached, and the correct COM port is being used. 5. Click to highlight the model and click Next. 6.
Chapter 5 – Firmware Upgrade 7. When the flash upgrade is complete, Programming Complete appears. 8. Click Next. The Results window appears. 9. Click Finish to exit Flash Wizard.
