A.4 Upgrading the Series II Modem’s Firmware

The Series II Modem has a Flash PROM which contains firmware code for the hardware and DSP code for the digital signal processor chips. At various times, we may add enhancements and/or fixes to the firmware.

The flash technology used in the Series II Modem lets you load these upgrades into the PROM or DSP chips through the modem's serial port. If a Black Box Tech Support technician tells you that you need to upgrade your firmware, do so, taking these steps:

1.

Follow the technician’s instructions for downloading

FLASHPRO.ZIP and a new .HEX file from Black Box.

2. Unzip the FLASHPRO.ZIP file. Place this unzipped file and the

.HEX file in the same directory.

3. Run FlashPro by typing FLASHPRO, a space, -M and hitting

ENTER at the DOS prompt.

4. Highlight the "Configure" option in the MAIN MENU and hit

ENTER. Highlight "Active Port" and select the COM port to which you have your modem attached. Highlight "Baud Rate" and select the rate you want to program at. Hit ESC when finished.

5. Highlight the "Select File to Program" option in the MAIN MENU.

Highlight the .HEX file. Hit ESC when finished.

6. Highlight "Program Firmware" option in the MAIN MENU. When you are prompted to confirm the file to program, press "Y".

7. If you need more assistance programming FLASHPRO, then contact our tech support department again.
