Factors include the property, speed, the object’s spectral characteristics, exposure time, the light source characteristics, the specifications of the acquisition system and so on. The exposure amount (exposure time x light amount) is the most important factor in getting desirable images.

    3.4.1 RS-422 Input When using RS-422 for input, connect a differential input via twisted pair as shown in figure 3-4-2. For correct operation, make sure to connect GND. With RS-422, multiple receivers can be connected to one driver. In such a case, only terminate the furthest receiver. On this camera, setting the Terminate setting to ON activates the terminator.

  • Page 27: Ttl Input

    3.4.3 TTL Input To use TTL input, connect the camera as in figure 3-4-3 below. To avoid damaging the device, do not input a signal to the – pin. In addition, make sure that the Terminate setting is OFF and the terminator is inactive. If the terminator is active, the signal may not be received correctly.

  • Page 28: Lvds Output

    3.4.5 LVDS Output If the receiver requires LVDS input, it can be connected by attaching resistors to the camera outputs. Multidrop is not supported. Connect only 1 receiver per camera. In addition, be sure to check that the receiver side must be terminated. If not, correct signals may not be received.

  • Page 29: Relation Of External Trigger Input And Output

    3.4.7 Relation of External Trigger Input and Output The external trigger output uses the external trigger input driver as an intermediary as shown in figure 3-4-7. Therefore it is possible to switch the output ON/OFF by use of an enable resistor. For settings, see “4.2.6.4 Setting Line Source”.

    4.8 Pixel Correction Generally speaking, image sensors (CCD, CMOS and so on) have fixed pattern noise and photo response non-uniformity. When you use the lens, lens shadings and light sources also can cause non-uniformity. The camera is set to the optimal correction before shipping in order to provide images of high grade.

    5 Basic Camera Setting Checks 5.1 Before Power On Check whether there are any dents or scratches on the camera. There might have been damage to the camera’s connectors or internals during transport. ①Check the pin assignments of the power cable(See figure 3-3-1 and table 3-3-1) ②Check that your network device supports 1000-Base T and Jumbo Frames.

    6 Sensor Handling Instructions 6.1 Electrostatic Discharge and the Sensor The CMOS sensors are susceptible to damage from electrostatic discharge and can deteriorate as a result. Take care when handing the sensor. 6.2 Protecting Against Dust, Oil and Scratches The CMOS sensor window is part of the optical path and should be handled like other optical components with care.
