MegaPlus® Model ES 1.0 PRECAUTIONS CAUTION: A laser beam focused on the sensor, either directly or by reflection, can cause permanent damage to the sensor. Any laser powerful enough to produce localized heating at the surface of the sensor will cause damage, even if the camera power is off. A sensor damaged by laser light is NOT covered by the warranty. NOTE: The ES 1.0 Series Cameras require a minimum of 10 minutes warm up time prior to operation.

MegaPlus® Model ES 1.0 1. INTRODUCTION 1.1 Introduction With spatial resolution of one million pixels, 30 frames per second (fps), and dual channel progressive scan readout, the Redlake MASD, Inc. MegaPlus Camera, Model ES 1.0, is well suited for scientific and industrial imaging applications. The compact camera package operates through an AIA connection to a host computer.
REDLAKE MASD, INC. NEW EQUIPMENT WARRANTY REDLAKE MASD, INC. MEGAPLUS CAMERA REDLAKE MASD, INC. (HEREAFTER REFERRED TO AS REDLAKE) WARRANTS THIS CAMERA, AND ACCESSORIES MANUFACTURED BY REDLAKE, TO FUNCTION PROPERLY FOR ONE YEAR FROM THE DATE OF SHIPMENT. Redlake agrees to perform the following equipment warranty services in the United States. 1. Repair service: if shipped to us, repairs will be made at no charge. 2.
MegaPlus® Model ES 1.0 2. CONTROLS AND CONNECTORS 2.1 Camera NOTE: A lens cap is installed on each camera to keep dust from getting on the optical sensor or components when it is shipped. Remove the lens cap and install your lens in a dust free environment. 2.1.1 Mounting the Camera The MegaPlus camera has a ¼-20 threaded screw hole for mounting purposes on the bottom of the camera body (see Figure 2-1). There is a second hole, 0.228 inches in diameter, to accommodate a locating pin.
REDLAKE MASD, INC. Figure 2-2. ES 1.0 Rear Panel 2.2 Camera Rear Panel 2.2.1 AIA Interface The AIA Interface is a 68-pin, high density, dual row, D type connector that connects the camera to a frame grabber board and a serial communication interface for camera control. The frame grabber board processes and displays video from the camera. A complete technical description of the connector and the signals that it carries is contained in Chapter 4 of this manual. 2.2.
MegaPlus® Model ES 1.0 2.3 Cables There are three different cables available to connect the MegaPlus Camera to your computer, as shown in Figure 2-3 below. Figure 2-3. ES 1.
REDLAKE MASD, INC. 2.4 Hardware Setup Follow the instructions supplied by the frame grabber manufacturer when you are using their cables to install your camera. If using Redlake supplied cables, connect the camera as shown in Figure 2-4 below. Figure 2-4.
MegaPlus® Model ES 1.0 2.5 Routine Maintenance There are no user serviceable parts inside the camera. The camera must be returned to the factory for repair if a malfunction occurs. The lens and the sensor cover glass should be cleaned according to good photographic practices. The camera can be ordered from the factory with an infrared filter installed in the lens mount. If an infrared filter was not ordered originally, a piece of clear glass will be installed in place of the filter.

MegaPlus® Model ES 1.0 3. CAMERA OPERATION 3.1 Introduction The MegaPlus camera, Model ES 1.0, does not have any manual controls on the camera itself. Camera operation is accomplished by commands sent to the camera through a serial data link from a personal computer (PC). The camera serial data link may be ordered from the factory as either RS232 or RS422. In either case, the command syntax is the same.
REDLAKE MASD, INC. 3.3 Error Messages The camera can respond to an erroneous command or query in one of four possible ways. MESSAGE FROM CAMERA ERROR-SYNTAX ERROR-ARG OUT OF RANGE ERROR-XMIT ERROR-HARDWARE ERROR EXPLANATION The camera cannot make sense of the command The command is recognized, but the argument is out of range or indecipherable The receiver detected a transmission error such as buffer overflow, parity, or framing An internal hardware error was detected 3.
MegaPlus® Model ES 1.0 3.4.3 Continuous The camera will take pictures at 30 fps in dual channel mode and 15 fps in single channel mode. The frame rate is fixed and is not varied by the exposure setting. The camera can be synchronized to an external trigger source through the TRIGGER input on the rear panel of the camera or the EXPOSE input of the AIA interface connector. The trigger input frequency must be between 29.5 and 30.5 Hz. If the camera is not externally triggered, its frame rate will be 29.5 fps.
REDLAKE MASD, INC. 3.4.6 Triggered Double Exposure Triggered double exposure is used in Particle Image Velocimetry (PIV) because of the short time between successive exposures. A triggered double exposure starts with the user-supplied trigger as illustrated in Figure 3-1 below. Figure 3-1. Triggered Double Exposure Timing Two images are captured in rapid succession by the camera in the triggered double exposure mode.
MegaPlus® Model ES 1.0 3.4.7 Mode Use this command to set the camera mode of operation. TYPE IN: MDE CS RESPONSE CR-LF EXPLANATION Sets the mode to continuous. MDE CD CR-LF Sets the mode to controlled. MDE TR CR-LF Sets the mode to trigger. MDE DE CR-LF Sets the mode to triggered double exposure. MDE? Queries the current mode setting. MDE xx Means the mode is set as indicated. NOTE: The FRS command sets the maximum frame rate limit in controlled and continuous modes.
REDLAKE MASD, INC. 3.4.9 Trigger This command selects the trigger source and polarity. There are two trigger inputs: the SMA connector on the rear panel of the camera (labeled TRIGGER), and the EXPOSE input carried by the AIA interface connector. TYPE IN: TRS AIA RESPONSE CR-LF EXPLANATION Selects the AIA interface connector EXPOSE signal as the trigger source. TRS EXT CR-LF Selects the TRIGGER connector on the rear panel as the trigger source. TRS? Queries the trigger source.
MegaPlus® Model ES 1.0 3.4.10 Transfer Pulse Delay This command sets the time between the initial edge of the strobe pulse to the initial edge of the transfer pulse in the triggered double exposure mode only. TYPE IN: TPD xxx RESPONSE CR-LF TPD? EXPLANATION Sets the delay in increments of 1 microsecond. The argument range is from 1 to 999 microseconds. If TPD is set to zero, the EXE value controls the first image exposure time permitting equal exposure time for both images.
REDLAKE MASD, INC. 3.4.12 Black Level The black level control functions much like the brightness control on a television set. The fixed video black level is set at the factory so that the output video is just above the black clipping level with the lens capped. The black level can be varied over a range of plus or minus 50 percent of peak white video. TYPE IN: BKF RESPONSE CR-LF BKE xxxx CR-LF BKE? EXPLANATION Sets the black level to an internal fixed value of approximately 10 counts above zero.
MegaPlus® Model ES 1.0 3.4.14 Digital Gain Sets the camera gain to a factor 1, 2 or 4. TYPE IN: DGN 1 RESPONSE CR-LF EXPLANATION Sets the camera gain to unity. DGN 2 CR-LF Sets the camera gain to times two. (Disabled for 10 bit operation) DGN 4 CR-LF Sets the camera gain to times four. (Disabled for 10 bit operation) DGN? Queries the current gain setting. DGN x Indicates that the gain is set to the factor value given. 3.4.
REDLAKE MASD, INC. 3.4.17 Strobe Polarity The strobe output on the rear panel of the camera provides a trigger pulse for the user. The polarity of the strobe signal is set by this command. The strobe output can drive a 50-ohm load and has a pulse width of 600 nanoseconds in older cameras. Cameras with software version 3.21 or higher have a strobe pulse width of 5µseconds; however the strobe pulse width is 600 nanoseconds in trigger double exposure mode.
MegaPlus® Model ES 1.0 Figure 3-2. Wedge Display 3.4.21 Display Wedge The wedge command displays linearly increasing gray scales in each quadrant of the image as shown in Figure 3-2. This function is useful for aligning the camera image to a frame grabber. The display wedge defaults to OFF when the power to the camera is turned off. TYPE IN: WDG ON RESPONSE CR-LF WDG OF CR-LF WDG? EXPLANATION Means the wedge is being displayed. Means the camera is imaging. Queries the state of the wedge display. 3.
REDLAKE MASD, INC. 3.5.2 Identification Query This command queries the camera for its model number and software version. TYPE IN: IDN? RESPONSE EXPLANATION Queries the camera for model number and software version. MEGAPLUS Model ES 1.0, Vx.
