Pin Error With Arduino Mega 2560

I have used the targetinstaller to enable Simulink support for the Arduino Mega 2560 board. I am running under WIndows 7 Ultimate (64 bit) and Matlab/Simulink 2012a.
When I try to specify a digital output of 22 I get an error that the Uno boards can only support up to 9 output pins. Since I am using a Mega 2560 I should be able to specify I/O pin addresses up to 53 or so. I have reinstalled the Mega 2560 targetinstaller but that had no effect.
Any suggestion?

Hi Randall, The model might be configured to run on the Uno. To change this, in your model, select Tools > Run on Target Hardware > Options. In the Configuration Parameters dialog that opens, change the Target Hardware setting to Arduino Uno.

Hi Rolfe, Thanks for your response. I had also found this solution once I experimented with the options under tools a few hours after I posted the question. It would have helped for the pin error to mention to check this but it was not too hard to find.

Thanks for the suggestion, Randall. I've added a comment to the help topic for that block, and will recommend your enhancement of the error message to a developer.
