Features 1.1 Features The Texas Instruments MC-1000WU-20A camera features the Texas Instruments TC215 solid-state monochrome charge-coupled-device (CCD) image sensor. The camera is for vision system applications requiring highresolution and high-sensitivity operation. The camera features include: - 1-2 TV frame rate, 15 Hz High sensitivity, 0.
Introduction 1.2 Introduction The MC-1000WU-20A is one of a series of high-resolution video cameras that employs TI’s mega-pixel CCD image sensors. The cameras are intended for scientific and industrial imaging applications where image data processing is required. The MC-1000WU-20A camera employs the TI TC215 full-frame CCD image sensor, which features 1,017,000 active photosites, resulting in a very-highresolution image.
Physical Description 1.3 Physical Description The MC-1000WU-20A camera is housed in an aluminum case 210.6 mm long (excluding lens) by 68.0 mm high by 68.0 mm wide. It is self-contained except for power supply and monitor. The camera weighs 2.09 pounds. The MC-1000WU-20A offers a standard TV C-mount lens attachment with an adjustable lens locking ring to allow precise adjustment of the lens back focal length. A variety of lenses or mechanical shutters may be used.
Equipment Supplied 1.
Equipment Required But Not Supplied 1.5 Equipment Required But Not Supplied The MC-1000WU-20A camera uses the full-frame TC215 CCD image sensor. This full-frame format sensor requires a mechanical shutter or an electronic light strobe to prevent image smear. The shutter or strobe light allows scene information to be captured during either the open time of the shutter or on-time of the strobe light.

Installation Procedure 3.2 Installation Procedure The following paragraphs describe installation procedures for the MC-1000WU-20A camera. 3.2.1 Mounting the Camera The camera can be mounted using any one of (??Two on page 1–4??) three 1/4 20-thread mounting holes located on the camera base plate. 3.2.2 Connecting an Auto-Iris Lens Most auto-iris lenses can be used with MC-1000 series cameras.
Post-Installation Test 3.3 Post-Installation Test When the power and monitor connections have been made, test the camera by applying power to the monitor and the external power supply (if used). The green power-on LED on the camera rear panel should light and an image should appear on the display. It may be necessary to operate the shutter control or frame-buffer hardware to obtain an image. In addition, the lens may require focus adjustment to obtain a sharp picture.
