Yes, the Homeyer driver works via the serial port. Note, however, that not all such filter wheels are compatible with the higher voltages on the RS-232 port. Damage to the filter wheel might result if the maximum input voltage is exceeded. We have only verified at this time that Homeyer wheels are compatible with this interface. The following circuit will convert the voltages on a serial port output to work with a CFW8-style filter wheel. Note: use this circuit at your own risk; incorrect wiring could damage the filter wheel.
