  • Page 11: General Introduction

    The Adimec-1000m is a monochrome camera module for Industrial Machine Vision and measurement systems. The Camera Link digital interface and the size of the camera make electrical and mechanical interfacing easy. All camera functions are remote controlled. This allows the camera to be optimized for a specific application.

  • Page 13: Precautions

    2. PRECAUTIONS A CCD camera is a sensitive device. Please read the following precautions carefully before you continue unpacking or operating the camera. 2.1 Safety precautions 2.1.1 General It is advised to unpack and handle the camera in a clean, ESD protected working area. It is advised to read the whole manual before using the camera.

  • Page 14: Cleaning Of The Ccd

    2.2.2 Cleaning of the CCD Cleaning of a CCD sensor is a rather difficult task. Depending on the aperture of the lens used, any dust particles with a size of 10 µm and larger can show up in your image. All cameras are checked for cleanliness in our factory before shipment.
  • Page 15 If this step does not result in an acceptable result, continue with step 2. 2. 2. 2. 2. Remove the lens mount by unscrewing the 4 crosshead screws that hold the lensmount (see figure 2-1). 3. 3. 3. 3. Clean the inner screw thread of the lens mount using Alcohol or Hexane and a Q-tip. 4.

    Take care during handling of the camera. The Camera Link connector and the power connector should not be damaged. The maximum tightening torque for the Camera Link connector may not exceed 0.26 Nm. Prevent the entry of foreign objects or dirt to the connectors, as this will result in unreliable operation or damage.

  • Page 25: Functional Description

    4. FUNCTIONAL DESCRIPTION This chapter contains a functional description of the Adimec-1000m camera. It describes the main functions and features of the camera using a simplified block diagram. 4.1 Block diagram • Figure 4-1 shows a simplified block diagram of the Adimec-1000m/S camera.
  • Page 26 The letters written between brackets in the block diagram correspond to the command that is used to control the module concerned. The CCD output is amplified and digitized. In case of the Adimec-1000m/D camera the gain differences between the two CCD outputs is corrected with an analog gain correction (AG)
  • Page 27 After the pixel re-map stage the digital gain (GA) is applied. The video data after the gain stage is mapped to the Camera Link ports. The output resolution is set to 8 or 10 bit (optional: 12 bit) (OR). The distribution of the two video outputs for 8 or 10 bit (optional: 12 bit) output is done conform the Camera Link Port specifications.

  • Page 28: Control Of The Camera

    4.2 Control of the camera The Adimec-1000m camera is fully software controlled via the Camera Link cable using a simple ASCII based protocol. It is possible to save settings as ‘power-up default settings’ in the camera. Delivered with the camera is a windows based application that can be used to interactively control the camera and load and save power-up default settings.

    LC or FD command failed. No power-up defaults or factory defaults found. This error indicates an internal NVRAM failure To increase the reliability of the whole system it is good practice to verify each command by executing the ERR? command. 4.2.8 Horizontal readout direction The horizontal readout direction can be set to normal or mirrored readout.

    This function only applies on the horizontal timing and data contents of the image. The blanking as well as the Camera Link LVAL timing is set to pass 1004 active image pixels or to pass all the 1024 pixels including the 2*10 dark pixels on the left and right side of the image.

  • Page 42: Image Format [Partial Scan]

    Partial Scan and/or vertical binning achieve this. When using partial scan only a programmed number of lines are readout from the CCD. The unwanted lines are dumped and will not appear on the Camera Link output. Also, performing vertical binning can increase the readout speed. This however will reduce the vertical resolution by a factor 2.

When selecting a new (or the same) operation mode the frame period, image format and integration time for continuous mode are verified for the selected mode of operation.

  • Page 46: Integration Time In Continuous Mode

    The current Frame Period can be read back from the camera Command syntax: FP? The minimum frame period is depending on the number of lines that are read out. The camera checks the specified frame period and adjusts it to the minimum possible if the frame period is set for a too small value for the current image format.
  • Page 47 The IT command only effects the integration period in the continuous mode. When operating in a different than continuous mode, the value is stored. The settings will become active when the camera is set to continuous mode.

  • Page 50: Optional Delayed Transfer Mode

    These calculations of Timage apply to both modes of operation. 5.3 Optional Delayed Transfer mode The Adimec-1000m can be ordered with the optional delayed transfer mode. The delayed transfer mode is used in applications where two images must be captured with very little time in between.

  • Page 51: Shutter Operation During Image Transfer And Image Readout

    5.4 Shutter operation during image transfer and image readout During the image transfer and image readout operations charge is transferred in the CCD. A shutter pulse during these operations can damage the image or cause visible cross-talk of the shutter pulse in the image. If the camera is executing an image transfer or image readout and a shutter operation is required (caused by an external event or even in continuous mode depending on the integration time) the shutter operation is not executed immediately.

  • Page 52: Image Transfer Request Prior To Image Readout Completion

    During the image readout a shutter operation is executed with a delay ranging from 0...19.6 µs when vertical binning is not used, or 0...26.0 µs when using vertical binning. Note that while not executing an image transfer or image readout the shutter operation is executed immediately.

  • Page 55 Figure 6-5: Vertical timing for Adimec-1000m/xx Note that the LVAL signal is not a continuous signal and that the time between successive LVAL periods (tHBLK in the timing diagram) is not fixed but depends on the image format and possibly inserted shutter operation.

  • Page 57: Communication Protocol

    The camera is controlled by a host system connected to the Camera Link interface using the serial communication link of the Camera Link. Commands and resulting data are transferred between the host system and the camera according a communication protocol.

  • Page 58: Message Format

    ACK or NAK character after the time-out period has elapsed the host system must consider the transmitted message as not being received by the camera. The time-out time to be used for the Adimec-1000m camera should be at least 200 ms.
  • Page 59 Under normal conditions a NAK or no response from the camera results from damage of the transmitted characters due to noise or communication link hardware problems. In such case the host system should transmit the message again. The number of repeated transmissions after a NAK response or no response must be limited by a retry count to prevent lock-up.
