2.1 Installation Overview

This installation overview assumes you have not installed any system components yet.

In order to set up your camera, you should take these initial steps:

1. Power down all equipment.

2. Following the manufacturer’s instructions, install the frame grabber (if applicable).

Be sure to observe all static precautions.

3. Install any necessary imaging software.

4. Before connecting power to the camera, test all power supplies.

Ensure that all the correct voltages are present at the camera end of the power cable (the Camera

Performance Specifications earlier in this document list appropriate voltages). Power supplies must meet the requirements defined in section 2.4

Power Input.

5. Inspect all cables and connectors prior to installation. Do not use damaged cables or connectors or the camera may be damaged.

6. Connect data, serial interface, and power cables.

7. After connecting cables, apply power to the camera. The POST (power on self test) LED on the back of the camera should glow green after one second to indicate that the camera is operating and ready to receive commands.

2.2 Input/Output

The camera provides 12-bit LVDS/RS-422 data and synchronization signals through the data output connector. Camera functions such as frame rate, integration time, binning, camera gain and offset are all controllable by the user via RS232 serial port. The camera is capable of free running operation or may be triggered externally via the input TRIGGER IN. TRIGGER OUT allows the synchronization of shutters or illumination sources in free running or externally triggered modes.

Note: Performance specifications are not guaranteed if your power supply does not meet these requirements.

DALSA offers a linear power supply (with cables) that meets the 6M3P’s requirements

(Universal Power Supply, part number 24-

00001-02, contact DALSA for more information), but it should not be considered the only choice. Many high quality supplies are available from other vendors. DALSA assumes no responsibility for the use of these supplies.

When setting up the camera’s power supplies, follow these guidelines:

• Do not connect or disconnect cable while power is on.

• Do not use the shield on a multi-conductor cable for ground.

• Keep leads as short as possible to reduce voltage drop.

• Use high-quality linear supplies to minimize noise.

VSYNC+, VSYNCVertical sync, true and complement--Output.

VSYNC high indicates the camera is outputting a valid frame of data.

2.6 Serial Communication

Connector and Pinout

The serial interface provides control of frame rate, integration time (shuttering), video gain and offset, pixel binning, external trigger and external integration (for information on how to control these functions, see “Operating the Camera” later in this document). The remote interface consists of a two-wire (plus ground) full duplex

RS-232 compatible serial link, used for camera configuration, and two back panel

SMA coax connectors used for external trigger input and output

GND TXD RXD

The camera uses an RJ-11 telephone-style connector for serial communications, with four conductors installed in a six-position connector. Note that both four- and sixconductor plugs may be used interchangeably with the RJ-

11 jack.

IMPORTANT: Both the PC/AT and the camera are configured as “DTE” (Data Terminal Equipment) devices requiring the

TXD and RXD lines to be swapped when interconnecting the two (note that pin 4, normally the yellow wire, is not

RJ-11

View into female jack

6-position with 4 conductors used on the RJ-11.) That is, the TXD pin represents DATA

OUT and the RXD pin represents DATA IN on both devices, so that one device’s

TXD line must connect to the other device’s RXD line and vice-versa.

Figure 4. 9 Pin Serial Port Connector to Camera RJ-11 Connector

Serial Communication Settings

The serial interface operates at RS-232 levels with fixed parameters of 9600 baud, 1 start bit, 8 data bits, 1 stop bit, and no parity. The interface uses only three wires, for received data, transmitted data, and ground. In general writing data must start with a write command byte and be followed by a data byte. Reading a camera register requires only a single read command byte.

6M3P Camera User’s Manual 13

The remote interface connector, on the cameras rear panel, is specified as a low-profile RJ-11 modular connector. The connector is a 6-position model, but only the center four positions are populated with contacts. It will mate with either the 4-position or 6position cable plugs. This type of connector typically requires special assembly tools; complete cable assemblies are available from suppliers such as Digi-Key:

Serial Cable Source

Digi-Key

701 Brooks Ave. South

Thief River Falls, MN 56701

1-800-344-4539 cable part number:

DALSA provides serial cables in 3 lengths: 10’, 20’ and 50’. Part number CL-31-00004-xx (where xx refers to the cable length in feet).

2.7 TTL Trigger Input and Output

Connector

The camera uses an SMA connector (labeled TRIGGER IN) to allow the user to provide a standard TTL signal to control camera integration and readout. The input is high impedance (>10K) allowing the user to terminate at the SMA input as needed.

The camera has another SMA connector (TRIGGER OUT) that provides a standard

TTL output which is high whenever the camera is integrating.

Integration

2.8 Integration Time

The minimum integration time (or shutter time) is 10

µs. If the camera is not strobed or externally shuttered, an integration time of 10

µs will create smeared images. To reduce smearing, the integration time should be 1.5x to 2x the readout time when not using a strobe or external shutter.

3.1 How to Control the Camera

The 6M3P’s RS-232-compatible serial interface allows you to control its configuration and operation, including:

ƒ

Triggering Mode

ƒ

Binning

ƒ

Frame Rate (See also triggering)

ƒ

Integration Time

ƒ

Gain and Offset

Command Protocol Overview

The camera accepts 8-bit command/value pairs via its RJ-

11 serial port using RS-232 compatible signals. Camera commands are “clock” commands, which apply to the electronics that drive the image sensor. These include clock generation, frame rate, integration time, and binning. Each set of commands includes read and write variants. With the exception of reset commands, all 8-bit write commands must be followed by an 8-bit data byte.

The commands are interpreted as follows:

Serial Port Configuration

Baud 9600, fixed

Start bits 1

Data bits

Stop bits

Parity

8

1

None

!

WARNING: Any commands not listed should be considered invalid. Writing to invalid

addresses may overwrite camera calibration information, requiring the camera to be returned for recalibration.

WARNING: Due to initialization sequencing after power-up, no commands should be sent to the camera for a minimum of 1 second after power up.

3.2 Control Register Reference

A number of functions and modes depend on the control register settings. These settings are detailed in the following sections.

The “Write Control Register” command is used to write a register that controls specific camera triggering and test functions. This command must be followed by a data byte with bits defined as shown in the following table.

The “Read Control Register” command allows interrogation of the camera to determine current configuration of the control register.

3.6 Adjusting Gain

Bit [6] of register 1 is the Video Gain control bit. When this bit=0 the video channel gain=1x. When this bit =1, the video channel gain=4x.

Example

Use this command to set the gain to 4x:

Note: The register containing the Gain bit also controls other configuration data. All bits must be set appropriately.

3.7 Adjusting User Offset

User offset is adjustable from -2047 to +2048 by a 12 bit value as an MS and LS byte. The offset data is only written when the most-significant 8 bits are written to register 2. Therefore, the lower 4 bits should be written first to register 3, followed by the upper 8 bits, which will cause the offset to be applied to the pixel output.

The pixel offset data is written as a 2’s compliment number. Therefore either positive or negative offsets can be added to the pixel output to enhance the image contrast.

The offset value that is programmed effects the pixel offset by a ratio of about 8 to 5.

So, for that example, if an offset value of a positive 16 is entered to registers 2 and

3 the resulting pixel data will be adjusted by a positive 10.

3.8 Controlling Binning

Binning increases the camera’s light sensitivity by decreasing horizontal and vertical resolution—the charge collected by adjacent pixels is added together.

The 6M3P is capable of up to 8 x 8 binning. To enable binning, you must write bits

[1:0] to control register 1.

Binning mode affects the pixel clock rate, maximum frame rate, and readout time.

3.9 Triggering, Integration, and Frame Rate Overview

Image capture triggering, integration, and frame rate are closely related.

ƒ

With electronic shuttering, integration time can be less than 1/frame rate, but it can never be greater than 1/frame rate.

ƒ

You can program fixed integration and frame rates (or use defaults) and let the camera “free run.”

ƒ

You can program fixed integration time and supply a (asynchronous) trigger signal to control frame rate, either by toggling a bit or by supplying a TTL pulse on the SMA connector. This is referred to as “Programmed Integration/External

Trigger Mode.”

ƒ

You can also have the camera integrate as long as an asynchronous TTL pulse is held high. This pulse will therefore control both integration time and frame rate.

This is also known as “External Integrate Mode.”

!

For a given frame rate, the maximum integration time is limited to the frame period less an overhead factor required for proper operation of the CCD. Maximum integration time is defined by this equation:

Max Integration Time = (1/Frame Rate) – Readout Time

This equation is valid for all binning modes, free running, external trigger and external integrate modes.

Note that binning mode impacts the Read Time and limits Integration Time.

WARNING: Do not set integration time higher than the limits of the equation above.

Unpredictable operation may result

ƒ

Programmed Integration/Free Running: (default) The camera free runs with the internally programmed integration time and frame rate

ƒ

Programmed Integration/SMA Trigger: The camera will integrate for the internally programmed time when triggered by a TTL high pulse on the SMA connector.

ƒ

Programmed Integration/Serial trigger: The camera will integrate for the internally programmed time when triggered by high signal on the serial interface.

ƒ

External Integration/SMA Trigger: The camera will integrate as long as the

TTL pulse on the TRIGGER IN SMA connector is high. The integration time is effectively the input pulse width. In this mode, TRIGGER IN also controls the frame rate.

ƒ

External Integration/Serial Trigger: The camera will integrate as long as the serial bit is held high. The integration time is effectively the input pulse width.

In this mode, the serial signal also controls the frame rate. Due to variation in the host operating system, this mode is generally used only for camera setup and functional testing.

Whenever the Integrate Mode or External Trigger Mode bits are set the MODE LED on the right side of the rear cover will light to indicate that an externally synchronized mode is active.

Free Running (Programmed Integration):

This mode is the camera’s default. The camera speed is controlled by writing a 3byte integration time value (in µs) to the three Integration Time registers. These three bytes are then combined to form a 24 bit integration time. The number represents the integer number of microseconds the camera will collect light. The number programmed in the three registers should not be below 10

µS (0000Ah). The camera will run at maximum speed for the programmed integration time.

DALSA C32-10005-01

6M3P Camera User’s Manual 25

The camera’s default integration time value is 638 ms which achieve 1 fps.

Example: Set integration time to 1000ms

Programmed Integration/SMA Trigger

For external SMA controlled triggering with a programmed integration time, a TTL rising edge on the TRIGGER IN (or SYNC) signal triggers the camera to acquire one frame of data. Integration begins within 200ns after the rising edge and stops when the programmed integration time has completed. After that single frame acquisition, the camera outputs the just acquired frame and “re-arms”, thus waiting for a new External Trigger signal to trigger a new frame acquisition. The camera is

“armed” when the read out of the acquired frame is completed. No additional rising

edges, or triggers, should be allowed during the image acquisition or frame read

out.

When the camera is in External Trigger Mode, the Frame LED will be illuminated on the camera back to indicate the camera is expecting a signal on the SMA connector or serial bit [7].

Because this signal is internally OR’ed with the Serial Trigger input, care must be taken to ensure the serial bit [7] of register 3 is equal to a logic 0 while in SMA

Trigger mode.

Programmed Integration/Serial Trigger

For external serial controlled triggering with a programmed integration time, a TTL rising edge on bit [7] of serial register 3 triggers the camera to acquire one frame of data. Integration begins within 200ns after the rising edge and stops when the programmed integration time has completed. After that single frame acquisition, the camera outputs the just acquired frame and “re-arms”, thus waiting for a new

External Trigger signal to trigger a new frame acquisition. The camera is “armed” when the read out of the acquired frame is completed. No additional rising edges, or

triggers, should be allowed during the image acquisition or frame read out.

DALSA C32-10005-01

6M3P Camera User’s Manual 26

When the camera is in External Trigger Mode, the Frame LED will be illuminated on the camera back to indicate the camera is expecting a signal on the SMA connector or serial bit [7].

Because this signal is internally OR’ed with the TRIGGER IN Sync input, care must be taken to ensure the TRIGGER IN signal is equal to a logic 0 while in Serial

Trigger mode.

External Integration/SMA Trigger

When in External Integrate/SMA mode, a TTL rising edge on the TRIGGER IN (or

SYNC) signal triggers the camera to acquire one frame of data. Integration begins within 200ns after the rising edge and stops within 550 ns after the falling edge.

After that single frame acquisition, the camera outputs the just acquired frame and

“re-arms”, thus waiting for a new External Trigger signal to trigger a new frame acquisition. The camera is “armed” when the read out of the acquired frame is completed. No additional rising edges, or triggers, should be allowed during the

image acquisition or frame read out. This means in this mode TRIGGER IN necessarily controls both integration and frame rate.

When the camera is in External Trigger Mode, the Frame LED will be illuminated on the camera back to indicate the camera is expecting a signal on the SMA connector or serial bit [7].

Because this signal is internally OR’ed with the Serial Trigger input, care must be taken to ensure the serial bit [7] of register 3 is equal to a logic 0 while in SMA

Trigger mode.

External Integration/Serial Trigger

When in External Integration/Serial mode, a TTL rising edge on serial bit [7] of register 3 triggers the camera to acquire one frame of data. Due to variation in the host operating system, this mode is generally used only for camera setup and functional testing. Integration begins within 200ns after the rising edge and stops within 550 ns after the falling edge. After that single frame acquisition, the camera outputs the just acquired frame and “re-arms”, thus waiting for a new External

Trigger signal to trigger a new frame acquisition. The camera is “armed” when the read out of the acquired frame is completed. No additional rising edges, or triggers,

should be allowed during the image acquisition or frame read out.

This means in this mode TRIGGER IN necessarily controls both integration and frame rate.

When the camera is in External Trigger Mode, the Frame LED will be illuminated on the camera back to indicate the camera is expecting a signal on the SMA connector or serial bit [7].

Because this signal is internally OR’ed with the TRIGGER IN Sync input, care must be taken to ensure the TRIGGER IN signal is equal to a logic 0 while in Serial

3.11 Controlling Frame Rate

The 6M3P allows you to control frame rate in three ways.

ƒ

Free Running (Programmed Frame Rate): (default) The camera free runs with the internally programmed frame rate time and integration time.

ƒ

External Trigger/Internal Integration: The camera frame rate will be controlled by the TTL pulse on the TRIGGER IN SMA connector. The camera will integrate for the programmed integration time. (Reference section 3.10

Controlling Integration Mode)

ƒ

External Integration: The camera frame rate will be controlled by the TTL pulse on the TRIGGER IN SMA connector. The camera will integrate for as long as the pulse is held high. In this mode, TRIGGER IN also controls integration. (Reference section 3.10 Controlling Integration Mode)

Free Running (Programmed Fame Rate)

This mode is the camera’s default. To specify programmed frame rate, you must set bit [7] of register 1 to 0 (Integrate Mode = Internal), and bit [3] of register 1 to 0

(Trigger Mode = Internal). Next, write the 3-byte frame rate value (in µs or 1/Frame

Rate) to the three Frame Rate registers. These three bytes are then combined to form a 24 bit frame rate time. The number represents the integer number of microseconds between frames. The number programmed in the three registers should not be below

10

µS (0000Ah), nor above the calculated value noted in section 3.9 Triggering,

Integration, and Frame Rate Overview.

Example: Set the Frame Rate to 2.5 fps

1.0 Reference section 3.9 Triggering, Integration, and Frame Rate Overview to ensure the desired frame rate can be supported for the selected binning and integration modes.

2.0 Using the command 82h, set bit [7] of the data byte to 0 (Integration Mode =

Internal) and bit [3] of the data byte to 0 (Trigger Mode = Internal).

NOTE: All bits within the register are written at one time. Ensure the correct value for all bits are used when changing camera modes.

3.0 Use commands 8Dh, 8Eh, 8Fh to set the 24-bit Frame Rate time value.

5.1 Cleaning

Electrostatic Discharge and the CCD Sensor

Charge-coupled device (CCD) image sensors are metal oxide semiconductor (MOS) devices and are susceptible to damage from electrostatic discharge (ESD). Although many sensor pins have ESD protection circuitry, the ESD protection circuitry in

CCDs is typically not as effective as those found in standard CMOS circuits.

Electrostatic charge introduced to the sensor window surface can induce charge buildup on the underside of the window that cannot be readily dissipated by the dry nitrogen gas in the sensor package cavity. When charge buildup occurs, surface gated photodiodes (SGPDs) may exhibit higher image lag. Some SGPD sensors may also exhibit a highly non-uniform response when affected by charge build-up, with some pixels displaying a much higher response when the sensor is exposed to uniform illumination. The charge normally dissipates within 24 hours and the sensor returns to normal operation.

Preventing ESD Damage

To prevent ESD damage, DALSA advises you to take the following handling precautions.

1. Ground yourself prior to handling CCDs.

2. Ensure that your ground and your workbench are also properly grounded.

Install conductive mats if your ground or workbench is non-conductive.

3. Use bare hands or non-chargeable cotton gloves to handle CCDs. NOTE:

Rubber fingercots can introduce electrostatic charge if the rubber comes in contact with the sensor window.

4. Handle the CCD from the edge of the ceramic package and avoid touching the sensor pins.

5. Do not touch the window, especially in the region over the imaging area.

6. Ground all tools and mechanical components that come in contact with the

CCD.

7. DALSA recommends that CCDs be handled under ionized air to prevent static charge buildup.

8. Always store the devises in conductive foam. Alternatively, clamps can be used to short all the CCD pins together before storing.

The above ESD precautions need to be followed at all times, even when there is no evidence of CCD damage. The rate which electrostatic charge dissipates depends on numerous environmental conditions and an improper handling procedure that does not appear to be damaging the CCDs immediately may cause damage with a change in environmental conditions.

Protecting Against Dust, Oil, and Scratches

The CCD window is part of the optical path and should be handled like other optical components, with extreme care.

Dust can obscure pixels, producing dark patches on the sensor response. Dust is most visible when the illumination is collimated. The dark patches shift position as the angle of illumination changes. Dust is normally not visible when the sensor is positioned at the exit port of an integrating sphere, where the illumination is diffuse.

Dust can normally be removed by blowing the window surface using clean, dry, compressed air, unless the dust particles are being held by an electrostatic charge, in which case either an ionized blower or wet cleaning is necessary.

Oil is usually introduced during handling. Touching the surface of the window barehanded will leave oily residues. Using rubber fingercots and rubber gloves can prevent contamination. However, the friction between rubber and the window may produce electrostatic charge that may damage the sensor. To avoid

ESD damage and to avoid introducing oily residues, only hold the sensor from the edges of the ceramic package and avoid touching the sensor pins and the window.

Scratches can be caused by improper handling, cleaning or storage of the sensor. Vacuum picking tools should not come in contact with the window surface. CCDs should not be stored in containers where they are not properly secured and can slide against the container.

Scratches diffract incident illumination. When exposed to uniform illumination, a sensor with a scratched window will normally have brighter pixels adjacent to darker pixels. The location of these pixels will change with the angle of illumination.

Cleaning the Sensor Window

1.Use clean, dry, compressed air to blow off loose particles. This step alone is usually sufficient to clean the sensor window.

2. If further cleaning is required, use a lens wiper moistened with alcohol.

3. We recommend using lint free, ESD safe cloth wipers that do not contain particles that can scratch the window.

4. Wipe the window carefully and slowly.
