OCCRA Teams,
I have successfully updated the firmware in the VEXnet transmitters and receivers that we used last year. Here is a partial list of the VEXnet hardware that was returned last year and I updated for use during the 2010 season.
Team 245, Team 51, Team 33, Team 43, Team 255, Team 573, Team 777, Team 802, Team 17, Team 1, Team 9. I also have 2 units that appear to be from Waterford and Roeper but are mismarked.
There is a VEXnet wiki utility that allows one to manually update your own hardware. It requires a male,USB A to A cable. IF you do this yourself, please email me to let me know this has happened successfully.
Another option is to bring your VEXnet transmitter and receiver to the VEX workshop where I can update both units after the workshop.
