I would expect what you described (setp ...-invert) to work. It's true that you can't setp a pin that is connected to a signal, but -invert is not connected to any signal.
When emc is running, open a terminal, run 'halcmd', then 'show param m5i20.0.out-03-invert'. This will show whether the pin is supposed to be inverted or not. Hm, looking at the source code, it appears that in the m5i20 driver the default value of -invert is TRUE. Perhaps you actually need to set it to FALSE to get the opposite polarity? The 7i37 isolation daughtercard has active-low outputs; this may have been done so that the default is compatible with the 7i37.
