FIRMWARE UPGRADE
MAXnet SERIAL MODE FIRMWARE UPGRADE
MAXnet User’s Manual
8-6
Verify that the controller is running the new firmware by running the MAXnScom utility and
sending a WY command to the controller. The WY response should indicate the version number
of the upgraded firmware.
If MAXnSupg 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 baud rate is 115200 baud.
- The default comm port selection is 1.
Examples:
