Configuration Script Example

The following script configures Data Forwarding frame grabbers for synchronized line-scan acquisition:

for (var grabber of grabbers) {
    if (grabber.InterfacePort.get("InterfaceID").includes('df-camera')) {
        console.log("Configuring slave card");
        // set the Width/Height/PixelFormat of the (virtual) remote device (on
        // the slave card) equal to the Width/Height/PixelFormat of the (real)
        // camera (connected to the master card)
        grabber.RemotePort.set("Width", 8192);
        grabber.RemotePort.set("Height", 1);
        grabber.RemotePort.set("PixelFormat", "Mono8");
        // configure the event input tool EIN1
        grabber.InterfacePort.set("EventInputToolSource[EIN1]", "A");
        grabber.InterfacePort.set("EventInputToolActivation[EIN1]", "StartOfScan");
        // configure the event input tool EIN2
        grabber.InterfacePort.set("EventInputToolSource[EIN2]", "A");
        grabber.InterfacePort.set("EventInputToolActivation[EIN2]", "EndOfScan");
        // configure start/end of scan triggers
        grabber.StreamPort.set("StartOfScanTriggerSource", "EIN1");
        grabber.StreamPort.set("EndOfScanTriggerSource", "ScanLength");
        grabber.StreamPort.set("ScanLength", 1000);
    } else {
        console.log("Configuring master card");
        grabber.RemotePort.set("TestPattern", "GreyDiagonalRampMoving");
        grabber.RemotePort.set("CxpLinkConfiguration", "CXP6_X4");
        grabber.RemotePort.set("CxpLinkConfigurationPreferredSwitch", "CXP6_X4");
        grabber.RemotePort.set("TriggerSource", "CXPin");
        grabber.RemotePort.set("TriggerMode", "On");
        grabber.DevicePort.set("CameraControlMethod", "RG");
        grabber.DevicePort.set("ExposureReadoutOverlap", "True");
        grabber.DevicePort.set("CxpTriggerAckTimeout", "0");
        grabber.DevicePort.set("StrobeDuration", "0");
        grabber.DevicePort.set("ExposureTime", "20");
        grabber.DevicePort.set("ExposureRecoveryTime", "0");
        grabber.DevicePort.set("CycleMinimumPeriod", "50");
        // configure start/end of scan triggers
        grabber.StreamPort.set("StartOfScanTriggerSource", "Immediate");
        grabber.StreamPort.set("EndOfScanTriggerSource", "ScanLength");
        grabber.StreamPort.set("ScanLength", 1000);
    }
}

Note: In this example, the start-of-scan trigger is the receipt of the start-of-scan event from the master, but the end-of-scan trigger is generated locally. One alternative would be to use EIN2 as EndOfScanTriggerSource.
