FIRMWARE UPGRADE
MAXnet ETHERNET MODE FIRMWARE UPGRADE
MAXnet User’s Manual
8-2
-
The first code block is re-written with a valid MAXnet signature so that the boot block will
recognize that valid firmware is loaded in the flash.
-
A restart command is sent to the controller, causing the controller to re-boot with the new
firmware.
Verify that the controller is running the new firmware by running the MAXnEcom utility and
sending a WY command to the controller. The WY response should indicate the version number
of the upgraded firmware.
If MAXnEupg encounters an error that will not allow it continue, it will either abort the program or
continuously retry until the error no longer occurs. In the case of a continuous error that does not
clear, the user can abort by entering Control-C (holding down the 'Ctrl' key and pressing 'C').
Unless specified via a command line option:
-
The default upgrade file name is maxn.bin.
-
The default IP address is 10.40.30.61.
-
The default TCP/IP port selection number is 23.
-
