Thank you for purchasing a QHY Filter wheel. I’m sure that it will give you hours of pleasure by saving you time swapping out filters. Please take the time to read this manual so you can familiarise yourself with some basic understanding of how the filter wheel works, and how to get the most from it. 1) How to connect your filter wheel When you first open your package, please check to make sure everything you ordered is there.
2) The connections : Power may be applied in either port With the spare port available for any other device that may also need power. Next connect the RS232 cable to the middle connector and connect the other end to a free RS232 port on your computer. You filter wheel should now have a similar image as this one on the right. Power Power RS-232 If you wish to use the QHY-9 camera as the filter wheel host, then replace the RS-232 cable with the cable specifically for the QHY-9, as shown in image.
) Using the filter wheel First you need to connect the RS-232 cable, then apply power. Connect to the filterwheel using your prefered imaging software. For instance, lets assume you have Maxim DL V5.xx. Start Maxim and select your camera as normal, but you will now be able to select your filter wheel. Simply click on the “Setup Filter” box and select “Ascom” as the filter wheel. Then click on the “Advanced” box in the bottom left and select “QHY 2”FW(RS232)” from the drop down menu.
Click “OK” to finish off the configuration, and select “Connect” to start your imaging session. You may now individually change filters by simply selecting the filter you want in the drop down list You may rename the filters if you like. Look up the help in Maxim DL on how to do this. In this example, Red is in Slot 1, Green in slot 2 and so on. In this example, the first slot (Red Filter) is selected, and the filter wheel will immediately move to the selected position if its not on it already.
5) Filter position calibration In the event you need to align the filter position with the camera position, please read the following. In some PC’s the mscomm32.ocx file should be registered (Run the “Install.bat” file). Run the “Color wheel calibration.exe” file found in “Manual control and calibration software” directory. Connect the Filter Wheel using the RS-232 cable. The Buttons 1 – 5 are the Filter Wheel control buttons.
