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.
Contents

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 Power Power
middle connector and connect the
other end to a free RS232 port on your
computer.
You filter wheel should now have a RS-232
similar image as this one on the right.
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.

3) Installing Driver
Place you supplied drivers disk in your CD Rom, and proceed to install the required drivers.
If you want a stand alone filter wheel (Not driven by the QHY-9), then proceed to install the
the driver “QHYFWRS232ASCOM.exe” found in the “Ascom RS 232 Driver” directory.
If you have a QHY-9, and wish to drive the filter wheel with your camera (Direct), then you will
need to install “QHY9FWASCOMSetup.exe” which is found in the “Ascom QHY-9 direct”
directory.
Please make sure that you have the latest version of Ascom installed on your PC.
