In order to set up your camera, you should take these initial steps:
This installation overview
assumes you have not
installed any system
components yet.
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 allthe 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 data and synchronization signals through the
data output connectors. 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.

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
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 RJ11 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
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.

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.

1M60 Camera User’s Manual14
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:
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.

Command Protocol Overview
The camera accepts 8-bit command/value pairs via its RJ11 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.

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.

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

All bits (*) must be set appropriately.
3.9 Adjusting User Offset
User offset is adjustable from -2047 to +20478 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
the MS Offset register. Therefore, the lower 4 bits should be written first to the LS
Offset register, 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.
Note: Register 3 contains other configuration data. All bits must bet set to the
appropriate values.

3.10 Triggering, Integration, and Frame Rate Overview
Image capture triggering, integration, and frame rate are closely related.
Integration time can be less than 1/frame rate, but it can never be greater.
You can program fixed integration and frame rates (or use defaults) and let the
camera “free run.”
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.”
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.

3.11 Controlling Integration (Shutter Time)
The 1M60 allows you to control integration (also known as exposure time or shutter
time) in five ways.
Programmed Integration/Free Running: (default) The camera free runs with
the internally programmed integration time and frame rate
Programmed Integration/SMA Trigger: The camera will integrate for the
internally programmed time when triggered by a TTL high pulse on the SMA
connector.
Programmed Integration/Serial trigger: The camera will integrate for the
internally programmed time when triggered by high signal on the serial
interface.
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.
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.
The register settings required for each mode are defined in the following table
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.
Register 1
Bit [3]

Free Running (Programmed Integration):
The camera speed is controlled by selecting the integration time value in the
Integration Time register. The camera will run at maximum speed for the
programmed integration time.
Example: Set integration time to 4ms (1/250 s)
1.0 Using the command 82h, set bit [7] of the data byte to 0 (Integration Mode =
Internal), bit [3] of the data byte to 0 (Trigger Mode = Internal), and bits [2:0]
to 101.
NOTE: All bits within the register are written at one time. Ensure the correct value
for all bits are used when changing camera modes.

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 2 us 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, ortriggers, should be allowed during the image acquisition or frame read out.
DALSAC32-10010-01
1M60 Camera User’s Manual24
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 2 us 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, ortriggers, should be allowed during the image acquisition or frame read out.
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 Connector
When in External Integration/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 2 us after the rising edge and stops 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 (850 us). This means in this mode TRIGGER IN necessarily
controls both integration and frame rate.
When the camera is in External Integrate Mode the red LED will light on the back
panel to indicate the camera is expecting a signal on the rear panel SMA connector.
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 Connector
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. Integration begins within
2 us after the rising edge and stops 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
(850 us). This means in this mode TRIGGER IN necessarily controls both
integration and frame rate.
When the camera is in External Integrate Mode the red LED will light on the back
panel to indicate the camera is expecting a signal on the rear panel SMA connector.

Because this signal is internally OR’ed with the TRIGGER IN Sync input, care must

3.12 Controlling Frame Rate
The 1M60 allows you to control frame rate in three ways.
Free Running (Programmed Frame Rate): (default) The camera free runs
with the internally programmed frame rate time and integration time.
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 3.10Controlling Integration Mode)
External Integration: The camera frame rate will be controlled by the TTL
pulse on the TRIGGER IN SMA connector. The camera will integrate fas 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)
To specify programmed frame rate, you must set bit [7] of register 1 = 0 (Integrate
Mode = Internal), and bit [3] of register 1 = 0 (Trigger Mode = Internal). Next, write
the frame rate bit value to the Frame Rate register.
Example: Set the Frame Rate to 30 fps
1.0 Reference section 3.10 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), bit [3] of the data byte to 0 (Trigger Mode = Internal), and bits [2:0]
of shutter control to 000.
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 command 88h to set bits [6:4] of control register 3 to the integration time
value 001.

Cleaning and Maintenance
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.
