10 FAQ
1. Does QHY183C support 10bit or 12bit?
QHY183C supports both 10bit and 12bit output(For 10bit, it is 0-255, and it only uses the high
8bit, for 12bit it is 0-4095 map to 0-65535).
2. How to get maximum FPS?
Since QHY183C has very high data bandwidth. Not all computer can get the maximum FPS.
Normally I7-4core should have no problem for that. The CPU loading will also affect the
maximum FPS. So please reduce the CPU load by close other applications when using camera. If
the CPU load is too high, the software may become very slow or hang.
3. How to avoid the camera hanging?
If you camera always hangs. It may be caused by many reasons. You can check the following
things.
3.1 If your computer is via chipset, or some type of the mainboard. In SharpCap it cannot get
image at all. (But in ASCOM it works well). In this condition, you need enable the DDR buffer of
the camera. Current SharpCap does not support the enable DDR function. The next version
SharpCap will support it.
3.2 If there is power leak for your mounts and computers? The power leak may cause the leak
current transfer from computer to the camera via the GND. This may affect the USB transfer and
cause the data packet lost and cause it hang. You need to make sure the computer and the
mount is well grounded.
3.3 If the USB port's voltage not enough? Some computer's USB port +5V is not enough. It may
cause the camera always hangs. In this condition you can use a powered USB3.0 HUB to connect
camera and get the good +5V power for camera.
3.4 If your CPU load is too high? If CPU load is too high, it will cause many frame lost and cause
the camera hangs. You can increase the USB traffic value to reduce the FPS and get more stable
video transfer.
3.5 If the USB cable connection is good enough? Sometimes the contact issue in the USB cable to
camera or USB cable to computer will cause the signal loss and cause camera to hang. Especially
when you move the cables. In this condition. You can try to add a little silicon oil into the USB
socket/plug .This can increase the contact a lot better.
3.6 Avoid the statics. Sometimes the static electricity on human body will cause the camera to
hang. You can touch the computer metal case for first before touch the camera to let the static
electricity on your body release.
