4. Additional Information
The code contained in the boot loader, which isused to update the firmware image,is not
part of the firmware it-self. This means that,the firmware can still be updated even if the
built-in firmwarehas been corruptedor does not exist. If the firmware update fails, simply
executethe update procedures again in BOOTP mode, as described in Chapter 3, and the
update should be successful.
The LRA-900-E obtains the IP address assigned by the user and retrieves the firmware image
through the utility program. Note that when updating the firmware, the LRA-900-E uses the
factory-default MAC address rather than any user-defined MAC addresses. The LRA-900-E
has a built-in flash protection feature that prevents any modification to the firmware stored in the
flash memory, before attempting to update the firmware, the “ Init Switch ” should be set to
the “ Init ” position and then the LRA-900-E can be powered-on and rebooted to disable the flash
protection. Since the flash
memory then be comes
writable, the firmware can
be updated via the
Ethernet network.
Notes:
Note1:
If the IP address settings do not work correctly (e.g. there is no response to a ping command),
please contact your network administrator to obtaina valid IP address for the LRA-900-E module.
Note 2:
If the settings displayed in the IP address field of the firmware update window is incorrect or
invalid (e.g. IP address: 0.0.0.0), then a valid IP address must be manually specified for the
LRA-900-E in order to process the update operation. Please contact your network administrator
to obtain avalid IP address before proceeding.
