Page 4: Introduction
CHAPTER 1 INTRODUCTION The QImaging Retiga EXi CCD digital camera features enhanced visible and IR quantum efficiency for super high sensitivity for demanding low light and fluorescence imaging applications. A progressive scan interline CCD sensor gives a resolution of 1.4 million pixels in a 12-bit digital output. High-speed low-noise electronics provide FireWire linear digital data for rapid image capture. -

Some laptop computers have 6-pin FireWire jacks that do not provide power. If your computer has such a port, you will have to power your Retiga EXi Fast 1394 by attaching an external power supply to the system. - Page 6 QCapture Suite Software The Retiga EXi Fast 1394 operates on both Windows and Mac OS based systems. QCapture Suite Software for both systems is available at . The easy-to-use QCapture software QIMAGING gives you complete control over the camera’s settings and image capture functions. QCapture Suite also includes a TWAIN-compliant interface that allows many Windows image-editing applications to acquire images using QImaging cameras.

Step 1. Install the 1394 PCI card (Windows Users Only) This step is for Windows PC users only. If you are installing the Retiga EXi Fast 1394 on a Mac OS computer, please skip to Step 2. -
Page 8: Step 2. Install Your Imaging Software
Once the IEEE 1394 card is installed in your computer, you are ready to install the FireWire drivers and imaging software. See your Imaging Software User’s Guide for complete installation instructions. Step 3. Connect the Retiga EXi Fast 1394 Once your imaging software is installed, connect your camera. There are two different types of connections. - Page 9 Connecting the camera to a PC/MAC desktop or MAC laptop Computer Perform the following for connecting your camera. • Remove the FireWire cable from the camera box, and plug one end of the cable into one of the camera’s FireWire sockets (either socket is fine).

If you turn off cooling (a setting in your imaging software), the amber LED will turn off too. Capturing Images with the Retiga EXi Fast 1394 Consult your imaging application’s user’s manual for more details. -
Page 14: Advanced Camera Controls
The External Trigger Port of the Retiga EXi Fast 1394 is a 6-pin miniature circular DIN connector. This port accepts digital logic signals that are used to control the camera's integration. The External Trigger Port is optically isolated from the camera's electronics. -
Page 15: Gain And Offset Controls
Table 1—Trigger Sources and Integration Modes Gain and Offset Controls The Retiga EXi Fast 1394's electrical gain and offset controls allow the user to map an image's intensities of interest to the camera's digital range. This mapping is performed in the analog domain and thus avoids the quantization errors incurred when the mapping is performed in the digital domain. -

If the image does not seem “sharp,” check the format of the lens or the coupler being used on the microscope. Retiga EXi Fast 1394 is equivalent to the CCD sensor and requires the appropriate lens or coupler. An incorrect coupler on the microscope will not provide the correct field of view, and will... -

Page 19: Glossary
CHAPTER 7 GLOSSARY Binning Binning is a method of increasing camera speed and sensitivity to boost low signals. Binning causes the acquired image to be brighter and smaller, but the resolution will be lower as a result. Because the image is smaller, the image transfer time is reduced significantly. When you select a binning setting in your imaging software, the camera combines data from several pixels in the camera’s CCD into a single super pixel. - Page 20 See IEEE 1394. IEEE 1394 High bandwidth (40 megabytes/second - 1394a; 80 megabytes/second - 1394b) interface for connecting digital imaging, storage, and other devices to host computers. Image Intensifier An electro-optical vacuum tube which intensifies or amplifies on low light level images. Integration The active collection of photons as done by an image sensor.

Pin 2 and should be a 5V TTL pulse. Output Signals There are two output signals provided on the Retiga EXi Fast 1394, SYNC A and SYNC B. SYNC A: This signal indicates the readout time of the camera and this signal is active high. A user could monitor this signal as a means of knowing when to trigger the next frame.
