Firmware
4.2.4 Via the Serial Port
The following procedure is for using the HyperTerminal software application. In some cases,
the HEX format file is available on the software CD and on the Web site.
Before you can load firmware through the serial port you need to convert the ROM code to
HEX format. There is a DOS application, R2H.EXE that can be used to convert the ROM file
to HEX format. The R2H.EXE application is available at ftp://ftp.lantronix.com/pub.
Put R2H.EXE and the *.ROM file into the same directory on a PC then open a DOS Window
to that directory and type:
C:\ R2H
filename
This will create a filename.hex file that you can load via the serial port.
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
on page
7-1
).
2.
Download the firmware to the unit using the
DL
command.
3. Select
Send Text File
and select the *.HEX file to be downloaded. The downloaded file
must be the
.HEX
(ASCII) version.
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.
*** NodeSet 2.0 ***
0>DL
02049 lines loaded.
Note:
You can only update your unit 's internal Web interface using TFTP or Device
Installer.
