See below for details. Otherwise, choose A. After saving the configuration, see if the camera works.

Some IIDC cameras know how to set the exposure integration time in physical units seconds. Others don't. If your camera does not support physical units called "absolute units" in the IIDC specification , there is no way to automatically determine the correspondence between the units used by the camera and the actual time interval.

Open the Device Property Browser, and look for the read-only property Camera supports integration time in physical units. If it says Yes , everything is okay. If it says No , read on. With cameras that do not support physical units, the exposure time is controlled with an integer X ranging from 0 to or some subrange thereof.

You will need to know two numbers, A and B , such that the actual interval T in microseconds can be expressed by this formula:.

The values for A and B depend on the camera model often even among cameras from the same vendor. Usually, the camera's manual will tell you what the values for A and B are, or how to compute them. In IIDC 1.

Which units you'll get will depend on whether the camera knows about dB units. However, there are some cameras that indicate they support dB units but actually only allow reading out values in dB the gain needs to be set using the camera's arbitrary units.

If this is the case with your camera, you may notice that the Gain dB slider will not work properly. This should allow you to set the gain in arbitrary units but view the value in dB units. The default setting will find the first available camera on the system. If you have multiple cameras, you may want to ensure that the same individual camera is always tied to the same named Micro-Manager device. To find the correct ID for your camera, first configure with a single camera connected to your computer with a blank Camera ID.

Some cameras provide pixel depth greater than 8 bits but less than 16 bits e. Let's say your camera has a bit AD converter but what follows applies to any actual bit depth.

  • When set to bit mode Mono16 , your camera will yield bit images in bit format. However there are two ways in which a camera can do so, and the behavior is vendor-dependent and cannot be auto-detected. Some bit cameras will return pixels with intensity values ranging from 0 to These cameras work correctly with Micro-Manager without further configuration. Other bit cameras will return pixels scaled to the full bit range 0 to You will be able to see this by examining an image snapped in a Mono16 video mode, with an object in the image bright enough to saturate or nearly saturate the intensity range.

    The histogram will show that there are samples that exceed the expected maximum for the camera bit depth 12 , and mousing over the image will show in the ImageJ status bar that every pixel has an intensity value that is a multiple of 16 2 raised to the power of 16 - In some cases, the intensity will be constant modulo In this case, you can turn on the Right-shift bit samples property in the Device Property Browser you may want to put this in your System - Startup preset. This will convert the image so that the pixels range from 0 to The setting has no effect in 8-bit video modes or importantly if the camera either says that it acquires at full bit depth or fails to report its bit depth.

    The default 0 should be fine in most cases. Double-click on the Built-in FireWire entry in the interface list. Enter the IP address you want to use, then click on Apply Now.

    When you return to the Network Status screen, you should see that the Built-in FireWire port is active and has the IP address you just assigned. On a Windows machine, open the Network Connections applet in the Control Panel, double-click on the icon labeled Connection and click on the Properties button in the pop-up dialog box. Enter the IP address you want to use.
