Connect to the Development Computer

The NI 177x Smart Camera can connect to the development computer directly or through a network. To configure the NI 177x Smart Camera through a network, the NI 177x Smart Camera and the development computer must be connected to the same subnet.

Caution

To prevent data loss and to maintain the integrity of your Ethernet installation, do not use a cable longer than 100 m. National Instruments recommends using a shielded twisted pair cable for maximum signal integrity.

Direct Connection

To connect the NI 177x Smart Camera directly to the development computer, complete the following steps.

1.

Connect the 8-pin female M12 connector to the 100/1G connector on the NI 177x Smart Camera.

2.

Connect the Ethernet connector to an Ethernet port on the development computer.

The NI 177x Smart Camera is now connected directly to the development computer.

Network Connection

To connect the NI 177x Smart Camera to the development computer through a network, complete the following steps.

Verify that the development computer is connected to the network and powered on.

2.

Connect the 8-pin female M12 connector to the 100/1G connector on the NI 177x Smart Camera.

3.

Connect the Ethernet connector to an Ethernet port.

The NI 177x Smart Camera is now connected through a network and is available for additional configuration with the development computer.


1-5



Subnet Considerations

To use the NI 177x Smart Camera on a subnet other than the one on which the development computer resides, first connect and configure the NI 177x

Smart Camera on the same subnet as the development computer. Next, physically move the NI 177x Smart Camera. Contact your network administrator for assistance in determining which network ports reside on the same subnet.

IP Address Assignment

If the NI 177x Smart Camera is connected directly to the development computer, the device will use a link-local IP address. If the NI 177x Smart

Camera is connected to a network that has a DHCP server, the device will automatically obtain an IP address. You can also configure the NI 177x

Smart Camera to use a static IP address. If you cannot locate the NI 177x

Smart Camera on the network, first refer to the

Firewall Configuration

section, then assign a static IP address or contact your network administrator.

Note

If the NI 177x Smart Camera IP address is 169.254.x.x, the device is only accessible from the local subnet. To access the smart camera from a remote subnet, configure the smart camera to obtain an IP address from a DHCP server or manually assign a static

IP address.

DHCP IP Addresses

Using a DHCP server to assign an IP address has the following advantages:

• The DHCP server manages the IP addresses of the network. You do not need to know the IP address of the NI 177x Smart Camera.

• The DHCP server does not allow other devices to use the IP address that is already assigned to your NI 177x Smart Camera.

Although using a DHCP server simplifies IP address configuration, using a static IP address can be more reliable. Consider the following potential issues before using a DHCP server to assign an IP address to the NI 177x

Smart Camera:

• If the network has both static IP addresses and IP addresses managed by a DHCP server, the DHCP server must be configured to not use reserved static IP addresses. If the DHCP server is not configured this way, the DHCP server can assign a reserved IP address to another device, causing address conflicts on the network, which results in some devices being unreachable.


1-6 ni.com


When a NI 177x Smart Camera configured for DHCP starts, it must be able to connect to the DHCP server. If the NI 177x Smart Camera cannot connect to the DHCP server and is not connected to the same subnet as the development computer, it does not appear in MAX or Vision Builder AI.

Note

A NI 177x Smart Camera connected directly to the development computer or to the same subnet as the development computer is always configurable from MAX or Vision

Builder AI, regardless of the IP address settings.

Firewall Configuration

If you are having difficulty detecting the NI 177x Smart Camera on your network, you must configure the firewall to open the TCP/UDP ports used by the NI 177x Smart Camera and the host machine. The required ports are

listed in Table 1-2.

Port

Connecting Lighting and

External Devices

This chapter provides information about connecting the NI 177x Smart

Camera to external devices, including external lighting and triggering devices.

Connecting Lighting Devices

To connect a light directly to the NI 177x Smart Camera, connect the

LED_DRV signal to the positive terminal on the lighting device. Connect the ground of the NI 177x Smart Camera and the lighting device to a common ground.

The controlled current output sources current for a LED lighting device.

You can control the amount of current by specifying a value between 0 and

500 mA, in 256 steps.

To configure a light, you can enter the lighting data manually in MAX or

Vision Builder AI:

• MAX—Select the Lighting tab of the NI Smart Camera configuration page and click Configure Light. The light must be configured in

MAX before you can use it in LabVIEW.

• Vision Builder AI—Select the Lighting tab of the Acquire Image

(Smart Camera) step and click Configure Light.

Connecting a Light Controller

You can connect a light controller to the NI 177x Smart Camera in order to control any connected lighting devices.

Caution

The controlled current output is an unregulated output dependent on the range of the power supply provided to the device. If the power provided to the device is ±10% with

+5% AC ripple, the controlled current output could be as high as 27.6 V. If the provided power exceeds the input voltage specifications of the third-party lighting controller, do not connect the controlled current output to the controller to prevent damage to the controller.

Use a power supply with tolerances that meet the requirements of the controller.

Protecting Against Inductive Loads

When an inductive load, such as a relay or solenoid, is connected to an output, energy stored in the inductor may cause a voltage spike when power is removed. This flyback voltage can damage the outputs and the power supply.

The Power & I/O Accessory for NI 177x Smart Cameras (781993-01) includes integrated flyback diodes so that no additional wiring is required.

If you are not using the Power & I/O Accessory for NI 177x Smart

Cameras, you must install a flyback diode to limit flyback voltages at the inductive load. Mount the flyback diode as close to the load as possible.


4-4 ni.com


Use this protection method if you connect any of the open collector outputs directly to an inductive load.

Connect the NI 177x Smart Camera output and the negative side of the load to the diode anode and connect the positive side of the load to a +24 V

power supply and the diode cathode, as illustrated in Figure 4-4.

Field of View

The field of view is the area under inspection that will be imaged by the

NI 177x Smart Camera. It is critical to ensure that the field of view of your system includes the object you want to inspect.

system, use Equation 5-1 and the specifications for the image sensor of

your device, as listed in Appendix A,

Active Pixels is the number of pixels in either the horizontal or vertical direction,

Working Distance is the distance from the front element (external glass) of the lens to the object under inspection, and

Image Sensor Spectral Response

The spectral response curve describes the relative sensitivity of the sensor to different wavelengths of light. If you are imaging a dim scene, this information can be useful when selecting a light source to use in your application as the camera is most sensitive at its peak responsiveness. It also helps determine if your application might require filters to remove undesired wavelengths of light from the scene.


Specifications

, to find the normalized spectral

response curves for each image sensor.

Gain

For example, if the working distance of your imaging setup is 100 mm, and the focal length of the lens is 8 mm, then the field of view in the horizontal direction of a NI 177x Smart Camera using the VGA sensor is

FOV horizontal

=

×

8 mm

× 100 mm

=

59.2 mm

Similarly, the field of view in the vertical direction is

(5-2)

FOV vertical

=

×

8 mm

× 100 mm

=

44.4 mm

(5-3)

Based on the result of Equations 5-2 or 5-3, you can see that you might

need to adjust the various parameters in the FOV equation until you achieve the right combination of components that match your inspection needs.

This might include increasing your working distance, choosing a lens with a shorter focal length, or changing to a high resolution camera.

Gain is a multiplier applied to the analog signal prior to digitization.

Increasing the gain increases the amplitude of the signal. Gain allows you to trade off between making smaller signals more visible at the cost of increased noise and no longer being able to differentiate between larger signals. For most applications, the NI 177x Smart Camera default gain setting optimizes the balance between small signals and large signals.

Figure 5-2. Effect of Gain on the Video Signal

In Figure 5-2a, low gain has been applied to the signal. The pixel values in the image are grouped close together. In Figure 5-2b, medium gain has

been applied to the signal; there are now more notable differences in pixel

value within the image. In Figure 5-2c, high gain has been applied to the

signal; at high gain, mid-range and bright portions of the image are now

both represented as white, the highest pixel value. In Figure 5-2c, several

bright areas of the image have been clipped to the maximum pixel value, and you can no longer distinguish subtle shading in the brightest areas of the image.

Gain can be useful when there is not enough available light and you need to increase the brightness of your images. However, increasing gain multiplies both the signal and noise. When possible, it is preferable to add additional lighting.

Auto White Level (NI 177xC Smart Cameras)

NI 177xC Smart Cameras allow you to adjust the gain for each color plane in the RGB color space. The white level specifies the point at which values in the red, green, and blue color planes converge to produce white. To obtain an accurate white level, either adjust each gain value manually or use automatic white level adjustment with a test image. For best results the image should contain a neutral reference, such as a gray piece of paper or a reference card.


5-4 ni.com


Black Level (NI 177xC Smart Cameras)

The black level specifies the image brightness. Set the black level to the pixel value which corresponds to true black. If the black level is innacurate, near-black pixels may be displayed as black or black objects may appear gray in the output image.

There are multiple ways to adjust gain values or enable automatic white balance adjustment:

• MAX—Use the settings on the Camera Attributes tab of the device configuration page.

• Vision Builder AI—Use the settings on the Advanced tab of the

Acquire Image (Smart Camera) step.

Look-Up Table

There are multiple ways to adjust gain values or enable automatic white balance adjustment:

• MAX—Use the settings on the Color tab of the device configuration page to adjust gain levels or enable automatic white level adjustment.

• Vision Builder AI—Use the settings on the Color tab of the Acquire

Image (Smart Camera) step to adjust gain levels or enable automatic white level adjustment.

A look-up table (LUT) transformation maps pixel values in the source image into other values in the transformed image. For example, you can use a LUT transformation to improve the contrast and brightness of an image.

Note

NI 177xC Smart Cameras allow you to define a LUT for each color plane in the RGB color space.

To enable a LUT in MAX, use the LUT Controls on the Camera

Attributes tab of the device configuration page.

Refer to the NI Vision for LabVIEW Basics Help for information about a using a LUT transformation to improve images in LabVIEW. To open this document, navigate to Start»All Programs»National Instruments»

Note

Vision Builder AI does not support LUT editing for NI 177x Smart Cameras.

Maintenance

Do not touch the CCD sensor by hand or with other objects. The sensor can be damaged by electrostatic discharge (ESD), body oils, and particulate matter.

Use a lens mount cover whenever a lens is not mounted on the camera to protect the sensor from dust and dirt.

Avoid drastic temperature changes to prevent dew condensation.

When necessary, use the following procedure to clean the sensor at a workstation equipped with anti-ESD facilities. If dust sticks to the CCD, first attempt to blow it off from the side of the sensor using ionized air.

If oils are present on the sensor, clean the sensor with a cotton bud and ethyl alcohol. Be careful not to scratch the glass. Use only one pass over the glass per cotton bud to minimize the risk of recontamination and scratching.

Image Acquisition

This chapter contains information about acquiring images with the NI 177x

Smart Camera and explains the relationships between triggering, lighting, and exposure.

Exposure

The NI 177x Smart Camera provides control of the image sensor exposure time through software. The exposure time is the amount of time that light is allowed to strike the sensor to produce an image. When light strikes the surface of the sensor, it dislodges electrons. As more light strikes the sensor, more electrons are freed, creating a charge on the sensor.

For a given amount of light, the sensor collects more charge during a longer exposure time than a shorter exposure time. Because the charge is what is read out to produce the image, it is important to have an optimal amount of light and exposure time for your application.

Exposing the image sensor for too short of a time relative to the amount of light in the environment results in a dark, low contrast image. Exposing the image sensor for too long of a time relative to the amount of light in the environment results in a bright, low contrast image. When the image sensor is exposed for an appropriate amount of time relative to the light in the environment, acquired images will exhibit appropriate contrast to easily distinguish both dark and light features. Contrast is a key factor in obtaining good results from image processing algorithms.

In applications where the object under inspection is moving, the exposure time must be carefully considered. If the object moves significantly during the exposure, the resulting image is blurry and unsuitable for processing.

The maximum exposure time for imaging a moving object without blurring depends on the per pixel spatial resolution and the rate of motion of the object. The per pixel spatial resolution is the field of view, calculated in the

Field of View


Image Sensor

, divided by the number of pixels in the sensor. Together, this information can be used to calculate the maximum exposure. Assuming the object is moving

maximum exposure time.

) where

E max

is the maximum exposure time without blurring,

R is the rate of motion of the object either horizontally or vertically,

FOV is the field of view in the direction of motion, and

N is the number of sensor pixels in the direction of motion

(6-1)

For many applications that include moving objects, additional lighting is necessary to achieve good image contrast due to the short exposure time required to avoid motion blur.

Additionally, in many environments, the ambient light conditions vary too significantly to obtain consistent results without adding dedicated lighting.

For example, in a building with windows, the ambient light can vary significantly with weather. Also, standard fluorescent lighting flickers at a rate that is perceivable by the NI 177x Smart Camera. In these situations, the ambient light must be overridden with a dedicated light source to ensure reproducible results.

Acquiring Images

You can configure the NI 177x Smart Camera to acquire images based on internal timing or an external trigger signal. In both cases, the NI 177x

Smart Camera can acquire images at the camera’s maximum frame rate.

Refer to the

Maximum Frame Rate

section for information about factors

that affect the maximum frame rate.

Internal Timing

The NI 177x Smart Camera features two types of internally-timed modes: free-run mode and fixed-frame-rate mode.

In free-run mode, the device acquires images at the maximum frame rate allowed by the configuration.

In fixed-frame-rate mode, you can specify a frame rate that is less than or equal to the maximum frame rate.


6-2 ni.com


External Trigger

Use the trigger input to synchronize the NI 177x Smart Camera with an external event, such as the assertion of a signal generated by a proximity sensor. You can trigger the NI 177x Smart Camera at rates up to the maximum frame rate. Refer to the


section for

information about factors that affect the maximum frame rate.

To use an external trigger, the trigger signal must be provided on the

TRIG_IN+ and TRIG_IN– inputs to the camera and triggering must be

enabled in the software. Refer to the

, for information about connecting external signals.

You can enable triggering in the following software programs:

• Vision Builder AI—Select the Enable Trigger checkbox on the

Trigger tab of the Acquire Image (Smart Camera) step.

• LabVIEW—Set the value of the TriggerSource attribute to External

Trigger and set the value of the TriggerMode attribute to On.

• MAX—Select the Enable Trigger checkbox on the Triggering tab of the device configuration page.

Figure 6-1 illustrates the relationship between an external trigger, a lighting

strobe, and the exposure time.

Figure 6-1. Externally Triggered Mode

6-3



The trigger shown in Figure 6-1 represents an external trigger, configured

to use the rising edge as the active edge. The time between the active edge of the trigger and the assertion of the lighting strobe is a user-configurable trigger delay. The trigger delay can be configured in either milliseconds or edge counts.

The amount of time required from the assertion of a trigger to the start of the light strobe and image exposure varies by application. For example, if a sensor that detects the presence of a part is positioned before the NI 177x

Smart Camera on a conveyor belt, a trigger delay is required to ensure that the image is not exposed until the part to be inspected passes in front of the

NI 177x Smart Camera. In this case, specifying the trigger delay in terms of edge counts allows the NI 177x Smart Camera to expose the image when the part is in position regardless of changes in conveyor belt speed. For other applications, a delay specified in milliseconds is sufficient.

If you are strobing a light, there is a delay of 500

μs while the lighting controller turns on the light.

After the lighting turn-on time, the exposure begins. The width of the exposure pulse determines how long the sensor is exposed. The exposure time can be adjusted by setting the Exposure Time control in Vision

Builder AI, setting the ExposureTime attribute in LabVIEW, or by setting the Exposure Time control in MAX. The lighting strobe deasserts at the end of the exposure pulse. The end of an exposure starts the image readout from the sensor.

The maximum trigger rate is determined by the maximum frame rate

for your configuration. Refer to the


section for information about the factors that affect the maximum frame rate.


6-4 ni.com


Maximum Frame Rate

Frame rate is the inverse of the frame period. The frame period is the time from the start of exposure on one frame to the start of exposure on the next

frame, as shown in Figure 6-2.

Figure 6-2. Frame Period

The frame period is affected by the following factors:

•

Exposure time, as described in the

Exposure

section of this chapter

•

Trigger delay, as described in the

External Trigger

section of this chapter

Determining the Maximum Frame Rate

You can determine the maximum frame rate for your configuration in software by reading the Max Frame Rate indicator in Vision Builder AI, reading the AcquisitionFrameRateLimit attribute in LabVIEW, or reading the Max Frame Rate indicator in MAX.

When external triggering is enabled, do not trigger faster than the maximum frame rate. If a trigger occurs faster than the maximum frame rate, the camera exhibits the following behavior. If an incoming trigger is received during exposure, the incoming trigger is ignored. If an incoming trigger is received during readout, the trigger is delayed until readout concludes.


6-5



Use Equation 6-2 to understand how software determines the maximum

frame rate:

max frame rate

=

min frame period

(6-2) where min frame period is the minimum amount of time for the strobe

and trigger mode, as described in the Calculating the Minimum

Frame Period section.

Determining the Exposure Time

The minimum frame period depends on exposure time, lighting mode, and trigger delay.

A longer exposure time results in a longer frame period, and a slower maximum frame rate.

Determining the Trigger Delay

If the trigger delay is set longer than the untriggered minimum frame period, the trigger delay value further limits the min frame period. When the trigger delay is specified in milliseconds, the software includes this in the calculation of the maximum frame rate indicator.

Calculating the Minimum Frame Period

Refer to Equations 6-3 and 6-4 to calculate the minimum frame period for

untriggered acquisitions with and without strobing.

Device Initialization

While the NI 177x Smart Camera initializes, the Power and Status LED indicators exhibit behavior described in the following table:

Table 7-1. LED Indicator Behavior during Device Initialization

Indicator Name

Power

Status

LED Behavior

Red for 0.5 seconds then solid green

Red for 0.5 seconds then off

If both the Power and Status indicators continuously display solid red, your device has experienced a critical error and you should contact NI support.

Power Indicator

The Power indicator provides information about the power supply. The

Power indicator is green while the camera is properly powered on. When no power is being supplied to the NI Smart Camera, the Power indicator is unlit. When power is first applied to the device, the Power indicator flashes red for one second while internal systems power up. If the Power indicator stays red for longer than one second, it indicates that the voltage is out of range.

Status Indicator

The Status indicator provides information about the status of the camera.

The following table describes the behavior of the Status indicator:
