Can you switch any of the outputs at all?

If the issue is you can control the first 16 outputs but not 17-32 because you can't find a code in the 232 database, have a look at the codes in the 232 database ("CMX Series Advanced Mode")

Here's the command for output 9 to component input 14: V0914\r
the 09 and 14 would presumably be for the output and input, so try copying the commands, renaming them and replacing the numbers in the string as appropriate.
