The iPORT CL-GigE and CL-U3 External Frame Grabbers
Pleora’s iPORT™ CL-GigE and CL-U3 External Frame Grabbers provide systems manufacturers and
integrators with cost and design flexibility advantages by converting Camera Link® cameras into native
GigE Vision or USB3 Vision™ cameras. With these external frame grabbers, Camera Link® cameras
transmit both video and control signals over the simple, long-distance cabling of Gigabit Ethernet (GigE)
or the widely available SuperSpeed USB 3.0 bus.
RJ-45 Ethernet connector

Base Camera Link support
USB 3.0 connector
iPORT CL-U3 External Frame Grabber (example)
Base and Medium Camera Link support
Based on field-proven designs, these external frame grabbers deliver additional benefits including high
bandwidth output, extended operating temperature range, and extensive GPIO functionality enabling
real-time, low-jitter triggering of cameras, and synchronization of other vision system elements.
Video is transmitted from Base and Medium Camera Link cameras with low, predictable latency over a
GigE or USB 3.0 link. The connection at the workstation is a standard USB 3.0 port or a standard
Ethernet RJ-45 jack, eliminating the need for a desktop computer with an available peripheral card slot
for a traditional frame grabber. As a result, designers can reduce system size, cost, and power consumption
by using computing platforms with smaller form factors, such as laptops, embedded computers, and
single-board computers.
Pleora’s CL-GigE and CL-U3 External Frame Grabbers help systems manufacturers and integrators to
leverage the performance attributes of GigE and USB 3.0, including high-bandwidth, power over cable,
and plug-and-play usability. In addition, the frame grabbers support flexible configurations, allowing
multiple cameras to be aggregated to a single Ethernet port, when using an off-the-shelf GigE switch.
Complying fully with the GigE Vision, USB3 Vision, and GenICam™ standards, these external frame
grabbers ensure interoperability with third-party equipment in multi-vendor environments.

Frame Grabber Connections” on page 17 and “iPORT CL-U3 External Frame Grabber Connections” on page

Camera Link Connector
The CL-GigE External Frame Grabber supports Base Camera Link cameras, which stream image data to
the external frame grabber. The CL1 connector is used to connect a Camera Link camera to the external
frame grabber using one standard Camera Link cable, as outlined by the Camera Link standard. This
connector can process up to 24 bits of data from the camera, and provides the following Camera Link
control signals, as specified by the Camera Link standard: CC1, CC2, CC3, and CC4.
Camera Link
connector (CL1)
Power Over Camera Link (PoCL)
The external frame grabber is powered through an external power supply and can optionally supply power
to the camera using PoCL, in accordance to the Camera Link Specification, version 2.0. When powered
using PoCL, 4 W at 12 V is supplied to the Camera Link connector for compatible cameras.
To prevent the external frame grabber from attempting to supply power to a non-PoCL cable or camera, you
can enable the SafePower protocol. For more information, see “To enable Camera Link SafePower and view
the status (industrial models only)” on page 88.
Voltage Drop Monitoring
The external frame grabber includes a Voltage Dropped state that monitors a voltage drop from 12 V to
a voltage below 10.5 V for cameras using PoCL. If the voltage drops below 10.5 V for more than
20 ms, the external frame grabber returns to the PoCL Sensing state.

For information about viewing the SafePower status and the status changes that occur, including PoCL
Sensing, see “To enable Camera Link SafePower and view the status (industrial models only)” on page 88.
Mapping to the Serial Communication Interface
The CL1 Camera Link connector is mapped to the Bulk0 serial communication interface on the external
frame grabber.
Mapping of Camera Link Connector and 12-Pin Circular GPIO
Connector Inputs
The GPIO pins on the 12-pin GPIO circular connector allow an external signal to control a Camera Link
camera, and are typically used for triggering. For example, you can use a trigger to synchronize image
capture from multiple cameras or to synchronize image capture with an external device.
12-pin circular
GPIO connector
Using the Programmable Logic Controller (PLC), you can map the GPIO input signals (GPIO_IN3,
GPIO_IN2, GPIO_IN1, and GPIO_IN0) to the four camera control signals (CC1, CC2, CC3, and
CC4) on the CL1 connector.
There are 16 possible mappings of the GPIO signals. For information about using the PLC, see the
iPORT Advanced Features Guide, available on the Pleora Support Center (www.pleora.com).
12-Pin GPIO Circular Connector
The GPIO inputs and outputs on the 12-pin GPIO circular connector support a variety of differential
and single-ended inputs and outputs, such as HVTTL, LVDS, and LVCMOS.

Powering the External Frame Grabber
The CL-GigE External Frame Grabber can be powered through an external power supply or using Power
over Ethernet (PoE) which uses isolated PoE circuitry. If both options are connected at the same time, the
following rules are used:
1. If VIN < 9 V and PoE is supplied, the external frame grabber will be powered by PoE.
2. If VIN > 10 V and PoE is supplied, the PoE will be off and the external frame grabber will be
powered by VIN (10-16 V).
3. For PoCL operation, VIN must be in the range of 11.6 V to 13 V to meet the requirements of the
Camera Link specification, version 2.0.
9-10 V is not within the recommended voltage range and may cause a malfunction.
External Power Supply — Input Signals
The following table lists the input power signals for the CL-GigE External Frame Grabber from an
external power supply using the 12-pin circular connector.

Camera Link Connectors
The CL-U3 External Frame Grabber supports Base or Medium Camera Link cameras (depending on
your product model), which stream image data to the external frame grabber.
For the Camera Link Base models (the CL-U3B and CL-U3B-IND External Frame Grabber), the CL1
connector is used to connect a Camera Link camera to the external frame grabber using one standard
Camera Link cable, as outlined by the Camera Link standard. This connector can process up to 24 bits
of data from the camera.
For the Camera Link Medium models (the CL-U3M and CL-U3M-IND External Frame Grabber), the
CL1 and CL2 connectors are used to connect a Camera Link camera to the external frame grabber using
two standard Camera Link cables, as outlined by the Camera Link standard. These connectors can process
up to 48 bits of data from the camera.
iPORT CL-U3 External Frame Grabber Connections

All models provide the following Camera Link control signals on the CL1 connector, as specified by the
Camera Link standard: CC1, CC2, CC3, and CC4.
Camera Link connector (CL1)
iPORT CL-U3M External Frame Grabber (example)
Power Over Camera Link (PoCL)
The industrial models, which are powered through an external power supply, can optionally supply power
to the camera using PoCL. When powered using PoCL, 4 W at 12 V is supplied to each Camera Link
connector for compatible cameras, for a maximum of 8 W (4 W for Camera Link Base models and 8 W
for Camera Link Medium models), as outlined in the PoCL specification.
To prevent the external frame grabber from attempting to supply power to a non-PoCL cable or camera, you
can enable the SafePower protocol. For more information, see “To enable Camera Link SafePower and view
the status (industrial models only)” on page 88.
Voltage Drop Monitoring
The external frame grabber includes a Voltage Dropped state that monitors a voltage drop from 12 V to
a voltage below 10.5 V for cameras using PoCL. If the voltage drops below 10.5 V for more than
20 ms, the external frame grabber returns to the PoCL Sensing state.
For information about viewing the SafePower status and the status changes that occur, including PoCL
Sensing, see “To enable Camera Link SafePower and view the status (industrial models only)” on page 88.
Mapping to the Serial Communication Interface
The CL1 Camera Link connector is mapped to the Bulk0 serial communication interface on the external
frame grabber.

iPORT CL-GigE and CL-U3 External Frame Grabbers User Guide
Mapping of Camera Link Connector and 12-Pin GPIO Circular
Connector Inputs
The GPIO pins on the 12-pin GPIO circular connector allow an external signal to control a Camera Link
camera, and are typically used for triggering. For example, you can use a trigger to synchronize image
capture from multiple cameras or to synchronize image capture with an external device.
12-pin circular
GPIO connector
Using the Programmable Logic Controller (PLC), you can map the GPIO input signals (GPIO_IN3,
GPIO_IN2, GPIO_IN1, and GPIO_IN0) to the four camera control signals (CC1, CC2, CC3, and
CC4) on the CL1 connector.
There are 16 possible mappings of the GPIO signals. For information about using the PLC, see the
iPORT Advanced Features Guide, available on the Pleora Support Center (www.pleora.com).
Micro-B USB 3.0 Connector
The external frame grabber uses a Micro-B USB 3.0 connector for communication with your computer.
For the standard models, it also supplies power to the external frame grabber.
USB connector
For the industrial models, we recommend that you apply external power to the device BEFORE you connect
it to a USB port to ensure that adequate power is available.
iPORT CL-U3 External Frame Grabber Connections
35
Powering the Standard Models Over a USB 3.0 Connection
For the standard models, a USB 3.0 connection powers the external frame grabber.
When powering the standard models, 900 mA is required from the USB 3.0 port. Although 900 mA may
not always be used, it is requested from the port. If the host controller manages multiple ports and there
are other devices that draw a large amount of power (for example, another USB3 Vision device or a hard
drive), the host controller may not grant the requested 900 mA, resulting in dropped images, dropped
connection, or failure to connect. Similarly, on a USB hub, ensure 900 mA is available for the port.
The industrial models are powered using an external power supply. For more information, see “Powering
the External Frame Grabber” on page 36.
Locking Connectors
The external frame grabber has been designed to support the Micro-B locking connectors specified by the
USB3 Vision standard. The case includes threaded screw holes that comply with the connectors specified
in the standard.
The external frame grabber has been designed to provide the appropriate clearance around the vertical
USB 3.0 connector so that when a locking connector is attached, the screws will not damage the printed
circuit board (PCB).

Using Differential Inputs with Quadrature Encoders
This chapter provides information about the use of quadrature encoders and pertains to the following
external frame grabbers:
• CL-GigEB-IND: Industrial model of the enclosed CL-GigE External Frame Grabber for Camera
Link Base cameras
• CL-U3B-IND: Industrial model of the CL-U3 External Frame Grabber, available in mountable
enclosure or as a board set for Camera Link Base cameras
• CL-U3M-IND: Industrial model of the CL-U3 External Frame Grabber, available in mountable
enclosure or as a board set for Camera Link Medium cameras
Quadrature encoder sensors are often used to detect changes in the speed and motion in conveyor belt or
web systems. Two-phase quadrature encoders produce electrical signals that indicate the direction, speed,
and motion of the processed material on the web or conveyor. These signals are often used to control
camera triggering for providing uniform images under varying load conditions. The quadrature encoder’s
signals are typically processed by an external frame grabber that produces a trigger signal for the camera.
Quadrature encoders have a solid or hollow shaft that is mechanically connected to a motor or rotating
apparatus on the web or conveyor system. Two-phase quadrature encoders have two outputs labeled A
and B, which produce square wave signals when the shaft is rotating. These signals are 90° out-of-phase.
Using Differential Inputs with Quadrature Encoders
47
When the shaft changes rotation between clockwise and counter-clockwise directions, these signals
change phasing between +90° and -90°.
This change is used to detect direction of motion. The rate of the square wave signals is proportional to
the rotation speed of the shaft. This change is also used for detecting speed of motion. When these signals
are steady-state, and are not producing square wave signals, the motion has stopped.
Electrical Interfacing
The external frame grabbers have two differential pair inputs that are convenient to use with a wide range
of two-phase quadrature encoders. These inputs can be configured for differential LVDS, RS-422 and
HVTTL, or single-ended TTL, LVTTL, and HVTTL electrical signal levels. The industrial models have
switches labeled Differential Type and I/O Level, for configuring the inputs. For more information about
these switches, see “Differential Type and I/O Level Switches” on page 22.

Differential Connection
The following diagram illustrates a typical differential connection to a quadrature encoder.
Using Differential Inputs with Quadrature Encoders
49
Single-Ended Connection
The following diagram illustrates a typical single-ended connection to a quadrature encoder.
Processing Quadrature Encoder Signals
GpioIn0 and GpioIn1 are connected to quadrature encoder outputs A and B, respectively. These signals
are processed by the external frame grabber’s built-in programmable logic controller (PLC). For
information about using the PLC, see the iPORT™ Advanced Features User Guide available on the Pleora
Support Center.
Images are captured only when the conveyor belt or web is moving in the forward direction in this
example. When the conveyor belt or web moves in the forward direction, Signal A leads Signal B by 90°.
When the conveyor belt moves in the reverse direction, Signal A lags Signal B by 90°. The PLC provides
a trigger signal on the Camera Link control line Pb0CC0 only when Signal A leads Signal B by 90°.
50
iPORT CL-GigE and CL-U3 External Frame Grabbers User Guide
The Timer0 function in the PLC is used to generate the trigger pulse Timer0Out. Timer0 itself is
triggered by the falling edge of a Boolean combination of A and B signals, which obtains the correct
quadrature phase for the forward direction. Another Boolean combination is used to produce the trigger
signal Pb0CC0 from Signal B and Timer0Out; when the conveyor belt or web moves in the reverse
direction, Signal B masks the trigger pulse Timer0Out.
Timer0 is configured with the following settings to generate a trigger pulse. These values may need to be
adjusted depending on the selected camera model and system requirements.
Table 28: PLC Timer Equations
Equation
Description
TimerTriggerSource = TriggerInput
Sets the triggering source for the Timer to be its external trigger input.
TimerTriggerActivation = FallingEdge
Sets the Timer to trigger on the external source’s falling edge.
TimerGranularityFactor = Granularity30ns
Sets the interval of the Timer’s internal clock tick. For this example,
we recommend that the selected factor be at least 8x smaller than
the period of the highest frequency expected from the quadrature
encoder.
TimerDelayRaw = 1
Sets the delay time before the pulse can start. This is the “low”
period of the pulse after the trigger. This value represents the
number of Timer internal clock ticks.
TimerDurationRaw = 6
Sets the duration or “high” time of the pulse. This value represents
the number of internal clock ticks.
The signal routing block in the PLC is configured using the Boolean expressions below. GpioIn0 is
Signal A, and GpioIn1 is Signal B. Note that “!” in the Boolean expressions represents not or inverted.
Table 29: Signal Routing Block Equations
Equation
Description
Timer0Trig = GpioIn0 & !GpioIn1
Generates the trigger signal for Timer0 from signals 'A' and 'B'.
Pb0CC0 = !(Timer0Out & GpinIn0)
Masks the trigger for the camera when the conveyor belt or web
moves in the reverse direction.

Installing the eBUS SDK
This chapter describes how to install the eBUS SDK, and also provides information about installing the
required driver.
Before you can configure and control your external frame grabber, you must ensure that the eBUS SDK
and USB3 Vision driver are installed on your computer.
The following topics are covered in this chapter:
• “Installing the eBUS SDK” on page 62
• “Installing the Driver” on page 62
Installing the eBUS SDK
61
Installing the eBUS SDK
You can install the Pleora Technologies eBUS SDK on your computer to configure and control your
external frame grabber.
The eBUS SDK contains an extensive library of sample applications, with source code, to create working
applications for device configuration and control, image and data acquisition, and image display and
diagnostics.
It is possible for you to configure the external frame grabber and GigE Vision/USB3 Vision compliant
video sources using other GenICam compliant software, however, this guide provides you with the
instructions you need to use the Pleora eBUS Player application.
Installing the Driver
The eBUS SDK includes two drivers: the GigE Vision driver and the USB3 Vision driver. The drivers,
which enhance existing general-purpose drivers shipped with NICs and USB 3.0 controllers, increase
image acquisition throughput and performance, decrease latency and jitter, and minimize CPU
utilization.
The drivers are selected for installation by default during the eBUS SDK installation process. If you choose
not to install the drivers (or want to uninstall either driver), you can use the eBUS Driver Installation Tool.
The driver must be installed before you can use eBUS Player or any third-party SDK software to configure
the external frame grabber. If it is not installed, the software will not detect the external frame grabber.
62
iPORT CL-GigE and CL-U3 External Frame Grabbers User Guide
To use the eBUS Driver Installation Tool
1. Click Start > All Programs > Pleora Technologies Inc > eBUS SDK > eBUS Driver Installation
Tool.
2. Under GigE Vision or USB3 Vision, click Install or Uninstall.
After a moment the driver status changes. If you are installing a driver, the driver is installed across
all network adapters or USB3 Vision devices on your computer.
3. Close the eBUS Driver Installation Tool.
You may be required to restart your computer.
To see the versions of the installed drivers, click Help > About.

Configuring Your Computer’s NIC for use with the
CL-GigE External Frame Grabber
When using the CL-GigE External Frame Grabber and connected Camera Link camera, you may observe
high data rates (above 800 Mb/s) that are close to the physical limit of Gigabit Ethernet (1000 Mb/s).
This chapter provides guidance on how to configure your external frame grabber to maximize the
performance of your system.
The following topics are covered in this chapter:
• “Configuring the NIC for Communication with the CL-GigE External Frame Grabber” on page 66
• “Calculating the Required Bandwidth” on page 68
• “Understanding the Effect of the Features on Bandwidth and Performance” on page 68

65
Configuring the NIC for Communication with the CL-GigE
External Frame Grabber
For optimal performance, we recommend that you enable jumbo packets (also known as jumbo frames)
and set the receive descriptors to the maximum available value.
The instructions in this section are based on the Windows 7 operating system. The steps may vary
depending on your computer’s operating system.
To configure the NIC for optimal performance
1. In the Windows Control Panel, click Network and Internet.
2. Click Network and Sharing Center.
66
iPORT CL-GigE and CL-U3 External Frame Grabbers User Guide
3. In the left-hand panel, click Change adapter settings.
4. Configure the NIC for jumbo packets (more often referred to as jumbo frames) and set the NIC’s
Receive Buffers (Receive Descriptors) to the maximum available value. Using jumbo packets allows
you to increase system performance. However, you must ensure your NIC and GigE switch (if
applicable) support jumbo packets.
To complete this task, right-click the NIC and click Properties. Then, click Configure. The exact
configuration procedure, as well as the jumbo packet size limit, depends on the NIC.

Calculating the Required Bandwidth
To calculate the approximate bandwidth that is required, use the following formula. Keep in mind that
this calculation results in an approximate value, and does not take into account Ethernet, IP, UDP, and
GigE Vision overhead. Note that each image is broken up into many packets, which should be considered
when determining overhead.
PayloadSize (MB) x 8 x Frames Per Second = Bandwidth (Mbps)
PayloadSize is automatically calculated by the device, based on the selected image settings, which include
Width, Height, OffsetX, OffsetY, PixelSize, and any padding that has to be added to the image payload. To
see the PayloadSize, open eBUS Player, connect to the external frame grabber, and then click Device
control. PayloadSize appears in the TransportLayerControl category.
For example, for an external frame grabber configured to use HD_720p_60Hz with a PayloadSize of
1.84 MB, the equation would look like this:
1.84 MB x 8 x 60 Hz = 883.2 Mbps
Understanding the Effect of the Features on Bandwidth and
Performance
This section provides a summary of the features that you can adjust to maximize the bandwidth and
performance of your system. For detailed information about maximizing your performance, see the
Configuring Your Computer and Network Adapters for Best Performance Application Note, available on the
Pleora Support Center (www.pleora.com).
Width, Height, and Pixel Format
The Width, Height, and PixelSize have a direct effect on the bandwidth that is used between the CLGigE External Frame Grabber and the computer. Increasing the width and the height of the image will
result in larger frames being streamed from the external frame grabber.
Interpacket Delay
Burst traffic from the Sony Camera Link can cause AUTO_ABORT or MISSING_PACKET errors. To
avoid these errors, you can increase the interpacket delay (TransportLayerControl\GevSCPD) to spread
the burst effect. The interpacket delay is the time the CL-GigE External Frame Grabber waits before
sending each packet of an image. If GevSCPD is set too high, then you may observe that the
BlocksDropped (part of the Status statistics in the Image Stream Control dialog box) is increasing.
68
iPORT CL-GigE and CL-U3 External Frame Grabbers User Guide
Acquisition Frame to Skip
If the CL-GigE External Frame Grabber drops frames because of high bandwidth usage (close to 1
gigabit), you can reduce the bandwidth by adjusting the AcquisitionControl\AcquisitionFrameToSkip
feature.
You can set this feature to 2 to skip two frames and then send one frame, resulting in one out of every three
frames being sent, for example.
Packet Size
To decrease the CPU resources required to reassemble full frames, you can increase the
GevSCPSPacketSize. Doing so increases the size of each packet, resulting in fewer packets, thereby
reducing the amount of CPU that is used for packet reassembling. Depending on the
GevSCPSPacketSize you choose, you may need a NIC that supports jumbo packets.
You can also set the AutoNegotiation feature to True, which allows the eBUS SDK to negotiate the largest
packet size that the computer can receive. When acquisition starts, you can see the value that was
negotiated for the GevSCPSPacketSize feature.
On some occasions, your computer may display a Connection Lost error. This can occur when a NIC
does not properly support jumbo packets. If this occurs, you can either disable jumbo packets on the NIC
or disable the AutoNegotiation feature and set the DefaultPacketSize manually.
Please note that if you execute the DeviceReset command, the GevSCPSPacketSize is reset to 576. To
avoid this limitation, you can set the GevSCPSPacketSize manually or override this feature using the User
Set. The User Set is a feature that lets you save the changes you make to your external frame grabber
settings. For more information about User Sets, see the eBUS Player User Guide.

Automatic/Persistent IP Address
The Device Control dialog box allows you to configure a persistent IP address for the external frame
grabber. Alternatively, the external frame grabber can be configured to automatically obtain an IP address
using Dynamic Host Configuration Protocol (DHCP) or Link Local Addressing (LLA). The external
frame grabber uses its persistent IP address first, but if this option is set to False, it can be configured to
attempt to obtain an address from a DHCP server. If this fails, it will use LLA to find an available IP
address. LLA cannot be disabled and is always set to True.

Configuring How Images are Acquired
Depending on the device you use, eBUS Player provides you with a list of image acquisition modes. The
modes allow you to acquire images continuously or frame-by-frame. You can also save images to the
external frame grabber’s onboard memory so that you can retrieve them later.
Modes Standard on Most GigE Vision and USB3 Vision-Compliant Devices
Continuous, SingleFrame, and MultiFrame modes are usually standard for external frame grabbers.
Acquisition starts when the Play button is pressed (the AcquisitionStart command is executed).
eBUS Player Main Page
Device Control Dialog Box
Continuous Mode
This mode allows you to acquire images continuously and is the default mode for most external frame
grabbers.
Multiframe Mode
This mode allows you to acquire a fixed number of images. To configure the number of images, set the
external frame grabber’s AcquisitionControl > AcquisitionFrameCount feature.
You can set the AcquisitionControl > AcquisitionFrameCount feature in the Device Control dialog box,
as shown in the following image.
80
iPORT CL-GigE and CL-U3 External Frame Grabbers User Guide
SingleFrame Mode
This mode allows you to acquire a single image.
Recording and Readout Modes, Available on Pleora Devices
The recording acquisition modes allow you to capture images from a camera and store them in the
external frame grabber’s onboard memory. The readout acquisition modes allow images to be acquired
from the device’s memory at a slower rate, ensuring images are not lost.
These modes are helpful when you are working with a camera that transmits images at a rate that exceeds
the connection between the external frame grabber and the computer, resulting in dropped images. For
example, a Base Configuration Camera Link camera transmits images at up to 2.04 Gbps (2 taps, 12 bits)
but the connection to the computer might be only 1 Gbps. By using the recording and readout modes in
this example, you can capture and stream images from the camera without losing any images (as long as
there is space in the onboard memory).
The recording acquisition modes (ContinuousRecording, MultiFrameRecording, and
SingleFrameRecording) support back-to-back recording, which allows you to click the Stop and Play
buttons multiple consecutive times without clearing the onboard memory.
Acquisition starts when the Play button is pressed (the AcquisitionStart command is executed) when one
of the recording modes is selected.
Images can be stored in the external frame grabber’s onboard memory as long as there is space or until
there are 512 images in memory. For information about calculating how many images you can store, see
“Calculating How Many Images Can be Stored in Onboard Memory” on page 83.
If the USB cable is disconnected, or if the computer is restarted, all captured images will be lost.
Understanding When Images are Removed from the Onboard Memory
The following actions remove the images from the external frame grabber’s onboard memory:
• Streaming images from the onboard memory using one of the readout acquisition modes
(ContinuousReadout or SingleFrameReadout).
• Power cycling the device, which clears all images from the onboard memory.
Connecting to the External Frame Grabber and Configuring General Settings

• Making any of the following AcquisitionMode changes and then clicking the Play button
(AcquisitionStart command):

ContinuousRecording Mode
With this mode, images are acquired continuously and are stored in the device’s onboard memory until
the memory is full (or 512 images are stored in onboard memory). When this limit is reached, the external
frame grabber stops acquiring new images from the camera.
We recommend that you observe AcquisitionControl > BlockBufferCount (Expert or Guru visibility
level is required). When the value for this feature stops increasing, the memory is full. For information
about the actions that clear the images from onboard memory, see “Understanding When Images are
Removed from the Onboard Memory” on page 81.
To determine how many images can be stored in memory, see “Calculating How Many Images Can be
Stored in Onboard Memory” on page 83 .
ContinuousReadout Mode
With this mode, images are continuously read (and removed) from the device’s onboard memory. The
readout begins at the first image in memory. To see the number of images stored in onboard memory, see
AcquisitionControl > BlockBufferCount in the Device Control dialog (Expert or Guru visibility level is
required).
Readout continues until the Stop button is pressed (AcquisitionStop command is executed) or until the
last image has been sent by the device (BlockBufferCount will be 0).
82
iPORT CL-GigE and CL-U3 External Frame Grabbers User Guide
MultiFrameRecording Mode
With this mode, a fixed number of images are stored in the device’s onboard memory. To configure the
number of images, set the AcquisitionControl > AcquisitionFrameCount feature in the Device Control
dialog. Images can be read out from memory using ContinuousReadout mode.
A maximum of 512 images can be acquired at one time in MultiFrameRecording mode.
To determine how many images can be stored in memory, see “Calculating How Many Images Can be
Stored in Onboard Memory” on page 83.
If AcquisitionControl > AcquisitionFrameCount is set to a value that exceeds the amount of available
memory, the external frame grabber stops acquiring new images when the onboard memory is full (or
512 images are stored in onboard memory).
BlockBufferCount shows the number of images currently in memory. In MultiFrameRecording mode,
this number is cumulative: If the memory is empty and you acquire an image, BlockBufferCount will
match the AcquisitionFrameCount. If you stop and restart recording, BlockBufferCount will increment
(to a maximum of 512 images, depending on the image size) and will no longer match the
AcquisitionFrameCount.
For information about the actions that clear the images from onboard memory, see “Understanding
When Images are Removed from the Onboard Memory” on page 81.
SingleFrameRecording Mode
With this mode, a single image is saved in the external frame grabber’s onboard memory after each
AcquisitionStart command.
For information about the actions that clear the images from onboard memory, see “Understanding
When Images are Removed from the Onboard Memory” on page 81.
SingleFrameReadout Mode
With this mode, a single image is acquired from the external frame grabber’s onboard memory.
Calculating How Many Images Can be Stored in Onboard Memory
First, take note of the PayloadSize, which appears under TransportLayerControl in the Device Control
dialog box. Expert or Guru visibility level is required to access this feature.
The PayloadSize is automatically calculated by the device based on the selected image settings, which
include Width, Height, OffsetX, OffsetY, PixelSize, any chunk data, as well as any padding that has to be
added to the image payload.
Connecting to the External Frame Grabber and Configuring General Settings
83
For example, for a device configured to use Mono10p with images that are 1920 x 1080, the PayloadSize
is equal to 2 592 000 bytes per image or 2 472 MB (2 592 000 / 1 048 576).
After determining PayloadSize, you can use the following equation to determine the number of images
that can be saved in onboard memory:
Available onboard memory MB / PayloadSize MB = Number of images that can be saved
Using our example, the equation is:
120 MB / 2 472 MB = 48 images

Configuring Camera Link Settings
The external frame grabbers support one Camera Link Base or one Camera Link Medium camera
(depending on your model), which streams image data to the external frame grabber using one standard
Camera Link cable (for Camera Link Base models) or two standard Camera Link cables (for Camera Link
Medium models), as outlined by the Camera Link standard. Optionally, the industrial models can supply
power to the cameras using PoCL.
The CL-U3 External Frame Grabber supports both Base and Medium Camera Link cameras, while the CLGigE supports Base Camera Link cameras.
To ensure images are received properly, you must configure the general Camera Link settings, which
include specifying the sensor scan type (either areascan or linescan) and selecting the number of taps for
your camera. All of this information is provided by the camera manufacturer.
You can optionally enable the SafePower protocol, which enables PoCL and prevents the external frame
grabber from attempting to supply power to a non-PoCL cable or camera.
Supported Camera Link Configurations
The following table lists the supported Camera Link modes and sub-modes. All Camera Link Medium
configurations are supported, with the exception of the 3-tap configurations. For detailed information

network
Verify that the network activity LED and network
connection speed LED are active. If these LEDs
are illuminated, check the LEDs on your
network switch to ensure the switch is
functioning properly. If the problem continues,
connect the external frame grabber directly to
the computer to verify its operation. For
information about the LEDs, see “Status LEDs”
on page 30.
The external frame grabber
and computer are not on the
same subnet
Images might not appear in eBUS Player if the
external frame grabber and the computer
running eBUS Player are not on the same
subnet. Ensure that these devices are on the
same subnet. In addition, ensure that these
devices are connected using valid gateway and
subnet mask information. You can view the
external frame grabber IP address information
in the Available Devices list in eBUS Player. A
red icon appears beside the device if there is
an invalid IP configuration.

In a multicast configuration,
the external frame grabber
may not be configured
correctly
Images might not appear on the display if you
have not configured the external frame grabber
for a multicast network configuration. The
external frame grabber and all multicast
receivers (for example, a vDisplay HDI-Pro
External Frame Grabber) must have identical
values for both the GevSCDA and
GevSCPHostPort features in the
TransportLayerControl section. For more
information, see“Multicast Network
Configuration” on page 94.
In a multicast configuration,
your computer’s firewall may
be blocking eBUS Player
Ensure that eBUS Player is allowed to
communicate through the firewall.
Anti-virus software or firewalls
blocking transmission
Images might not appear in eBUS Player
because of anti-virus software or firewalls on
your network. Disable all virus scanning
software and firewalls, and re-attempt a
connection to the external frame grabber with
eBUS Player.
In a multicast configuration,
images appear on a display
monitor connected to a
vDisplay HDI-Pro External
Frame Grabber but do not
appear in eBUS Player.

Resolution
Dropped packets: eBUS
Player, NetCommand, or
applications created using
the eBUS SDK
Insufficient computer
performance
The computer being used to receive images
from the device may not perform well enough to
handle the data rate of the image stream. The
GigE Vision driver reduces the amount of
computer resources required to receive images
and is recommended for applications that
require high throughput. Should the application
continue to drop packets even after the
installation of the GigE Vision driver, a
computer with better performance may be
required.
Insufficient NIC performance
The NIC being used to receive images from the
GigE Vision device may not perform well
enough to handle the data rate of the image
stream. For example, the bus connecting the
NIC to the CPU may not be fast enough, or
certain default settings on the NIC may not be
appropriate for reception of a high-throughput
image stream. Examples of NIC settings that
may need to be reconfigured include the
number of Rx Descriptors and the maximum
size of Ethernet packets (jumbo packets).
Additionally, some NICs are known to not work
well in high-throughput applications.

performance of your system, see the
