Sierra Wireless DART 200 CDPD Modem - Manual (Page 177)

PN1197-00 Revision 1.0
G Loading DART 200
Firmware
Periodically, the DART 200 firmware needs to be updated, because of
improvements to the DART’s capabilities, corrections for problems, or to
keep pace with the evolving CDPD standard. When this need occurs, a
ZIP file containing the upgrade materials will be available on the Sierra
Wireless Web site. If you do not have Internet access this file will also be
available on diskette. The ZIP file will contain the new firmware, a
download program, and a README file with instructions for loading the
firmware onto your DART 200 modem.
The download program runs under DOS, and can run as standalone or in
a DOS window under Windows. To reduce the possibility of time-outs it
is recommended that the files and program be copied to a hardfile before
starting execution. Time-outs can still occur if running under Windows.
If a retry or two does not eliminate the timeout problem, try to download
at a lower speed. If that also times out then run the download function as
a standalone program outside of Windows.
When the download is complete the last step in the process is for the
loader to issue an AT&F&W to restore and save the DART’s factory
defaults. If the modem is personalized for application use, reprogram the
modem with its application specific profile and S-Register settings.
However, loading the new firmware does not disturb the modem’s IP
address(s) and associated credentials. When the download is complete,
the modem registers on the CDPD network with no problems.
Firmware download procedure
Perform the following steps to download the new software to the DART
200.
1. Make the appropriate connections by:
• Connecting the modem to a 12 VDC power supply
• Connecting the modem’s RS-232 interface to a serial port on
your PC
2. Power on the modem.
3. Check that the modem’s server functions are inactive before starting
the download process. Start your ASCII terminal emulator and enter
an AT&V command.
