Maintenance
1. Download the Full version of the update program which includes the program, associated
files and USB drivers. Also download the latest firmware for your modem from the web
site.
2. Unzip or extract the program files into the directory where you saved the download in
step one. An alternative is to leave the downloaded program files compressed - either
WinZip or Windows XP compressed folders will allow you to run the install program
directly from within the compressed file.
3. Run the "Install.exe" file by double clicking on it. This will create the C:\Program
Files\M500 FLASH Loader directory and place the program and associated files there.
The USB drivers will be in a sub-directory named. C:\Program Files\M500 FLASH
Loader\UsbDriver.
4. Unzip or extract the binary files into a suitable folder. You could use the C:\Program
Files\M500 FLASH Loader directory, or chose one within My Documents such as "M500
Binaries".
5. Connect the computer to the modem via a USB cable. If the modem is turned off then
turn it on. The computer will recognize and advise you that new hardware has been
found and run the new hardware wizard.
6. If the wizard asks if you would like to connect to the Internet to search for drivers, select
"No, not this time" and click "Next".
7. When asked if you want to "Install Automatically" or "Locate the drivers myself" or "Have
Disk", select the self locate or have disk option and navigate to the C:\Program
Files\M500 FLASH Loader\UsbDriver folder and there select the ftd2xx.inf file. Then let
windows do the rest. If notified that the driver is not certified select "Continue Anyway".
The supplied drivers are from a reputable source that manufactures the USB interface
chip.
The modem has a complementary program which talks to the loader and controls re-writing of the
flash memory. No actions to the modem are normally necessary before beginning update with the
exception of removing it from service, and the M500 Flash Update program can take care of all
tasks directly including finding the modem, determining if it has newer software/firmware versions
available and preventing loading of incorrect firmware to the modem The modem is specifically
designed to not accept firmware that is not made for it. For example the standard 70 MHz modem
would reject firmware for a 140 MHz or L-Band Modem.
It is a good idea to see if a later version of the update program or the update instructions are
available on the web. Those could be newer than the basic information given here.
4.3.2 Performing the Software/Firmware Update –
Once the PC program which does the actual update and communications with the modem is
installed the process for accomplishing the actual update using the original "M500 Flash Loader"
is as shown below.
⇒
Note: For virtually all users the recommended program is the newer "M500
Up_date.exe" program available on our web site at www.datumsystems.com. This newer
program in version 2.06 and later is significantly easier to use, works with any version of
Windows including Vista, and can check a special web site for available modem and
program updates on user command. This relieves the user from having to know about
numbering schemes, modem types, etc. Use instructions are also on the web site.
