    Images Detecting a Camera When you first open the QuickCam application, and after powering up the camera, QuickCam automatically detects all cameras on the network and asks you to set an IP address for each (or accept the suggested default). If you have multiple cameras on your network, ensure you give each one of them a unique IP address.

  • Page 25: Gpio Control

    QuickCam User’s Manul GPIO Control The GPIO connector allows the camera to receive (and in some cases output) direct, real-time control signals that are independent of Ethernet communications. Ethernet network protocols introduce a small but measurable and unpredictable lag that does not allow extremely precise and reliable control of camera behavior such as line rate, integration time, and readout direction.

  • Page 26: Gpio Input Labels

    The signals in the GPIO Control Block are defined in the tables below. Inputs to QuickCam are labeled In (where n is an integer from 0 to 7) and outputs are labeled Qn (where n is an integer from 0 to 15).

  • Page 31: Configuring The Gpio (With Examples)

    QuickCam User’s Manul 6. 3 Configuring the GPIO (With Examples) Overview As was mentioned in the introduction of this chapter, to configure the GPIO, you need to accomplish three main tasks: Step 1 The first step is to select and assign the GPIO connector pins and signal type to use for any necessary inputs or outputs.
  • Page 32 QuickCam User's Manual Step 2 Next you must map the GPIO input number and signal type set on the Exposure/GPIO tab to a GPIO Look-Up Table Input Configuration Label. Step 3 The final step maps the GPIO Look-Up Input Configuration Label to a GPIO Output Configuration Label.
