Connect the camera

Select “Camera Control Window” from the View menu to open the Camera Control

Window.

MaxIm will open the Camera Control window and display the Setup tab. After MaxIm is

installed it must be told which camera to use.

Click the “Setup” button in the upper left corner under Main CCD Camera.

QSI 500 SERIES USER GUIDE

Select “QSI Universal” from the Camera Model list box. Click OK.

That will take you back to the Camera Control Window. If you have a QSI camera with an

internal color filter wheel you’ll also need to tell MaxIm about that by clicking “Setup” under

“Filter Wheel” toward the upper right of the Setup tab.

Select “QSI Universal” as the filter wheel model. Click OK.

QSI 500 SERIES USER GUIDE

Click the “Connect” button to establish communication between MaxIm and your QSI

camera. If MaxIm fails to connect to the camera, double-check that power is supplied to the

camera and that the USB cable is securely connected. Once MaxIm connects to the

camera the Camera Control window will look like this:

Note: This example assumes the camera does not have a color filter wheel. If

you setup a filter wheel, “QSI Universal” will be displayed under Filter Wheel in

the dialog above.

Click the “Expose” tab along the top of the Camera Control window.

There are several fields and buttons in this window. On the left is a series of radio buttons

to select the type of frame to expose. The options are Light, Bias, Dark and Flat. Click the

button next to “Bias” to select a bias frame. A bias frame is an exposure with the shutter

closed of essentially zero exposure time. The Minutes and Seconds will be grayed

indicating that the exposure time can’t be modified for a bias frame. Make sure the Delay is

set to “0”. Click “Expose” to take one bias frame.
