4. Updating Firmware
Via the Serial Port
The following procedure is for using the HyperTerminal software application. This
procedure takes about 10 minutes.
Note:
Do not switch off the power supply during the update. A loss of
power while reprogramming will result in a corrupt program image and a
nonfunctional unit.
To download firmware from a computer via the unit’s serial port:
1. Enter Monitor Mode via the serial port (see
Monitor Mode
in the Troubleshooting
chapter).
2. Download the firmware to the unit using the
DL
command.
3. Select
Send Text File
and select the
SD21*.HEX
file to be downloaded. The
downloaded file must be the
.HEX
(ASCII) version.
Note:
For SDS1100, select the SD11*.HEX file to be downloaded.
4. After the final record is received, the unit checks the integrity of the firmware
image before programming the new firmware in the flash ROM. The following
message displays when the firmware upgrade is complete.
