Camera Hardware Interface
2.1 Installation Overview
(This installation overview assumes you have not installed any system components yet.)
When installing your camera, you should take these steps:
1. Power down all equipment.
2. Follow the manufactu rer’s instru ctions to install the framegrabber (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. Power supplies must meet the requirements defined in the
Power Connector section below.
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 and power cables.
7. After connecting cables, apply power to the camera.
8. Use the verify voltage (vv) command to verify that the camera is receiving a voltage of 12 to 15 DC. If the
camera is receiving less than the recommended voltage, then you may have to upgrade and/ or shorten
the power cable you are using.
8. Check the diagnostic LED. See LED Status Indicator for an LED description.
You must also set up the other components of your system, including light sources, camera mounts*, host
computers, optics, encoders, and so on.
*Please see 4.2 High Temperature and Mounting for more information on camera mounting and heat
dispertion.

2.2 Input/Output Connectors and LED
The camera uses:
A diagnostic LED for monitoring the camera. See LED Status Indicator in section LED Status Indicator for
details.
A 6-pin Hirose connector for power. Refer to the Power Connector section below for details.
The HSLink modles use a SFF_8470 / CX4 (with thumbscrews) for control, data and serial
communication.
The Camera Link model uses 2 high-density 26-pin MDR26 connectors for control, data and serial
communication.
Figure 1: Input and Output Connectors
WARNING: It is extremely important that you supply the appropriate voltages to your camera. Incorrect
voltages will damage the camera.
LED Status Indicator
The camera is equipped with an LED used to display the operational status of the camera. The table below

2.2.2 Power Connector
Figure 2: Hirose 6-pin Circular Male—Power Connector
The camera requires a single voltage input (+12 V to +15 V DC). The camera meets all performance
specifications using standard switching power supplies, although well-regulated linear supplies provide
optimum performance.
WARNING: When setting up the camera’s power supplies follow these guidelines:
Apply the appropriate, reliable voltages
Protect the camera with a slow-blow fuse between power supply and camera (2x nominal current).
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.
Use an isolated type power supply to prevent LVDS common mode range violation.
A stable supply of power must be maintained during code upgrades. Camera will fail if power is lost or
unstable while updating code. The user can not recover from this failure and the camera will have to be
returned to Teledyne DALSA for repair.
Note: Camera performance specifications are not guaranteed if your power supply does not meet these requirements.

EXSYNC
The camera ships in internal sync, internal programmed integration.
EXSYNC (Triggers Frame Readout)
Frame rate can be set internally using the serial interface. The external control signal EXSYNC is optional and
enabled through the serial interface. This camera uses the falling edge of EXSYNC to trigger pixel readout. See
section Exposure Mode and Line Rate for details on how to set frame times, exposure times, and camera
modes.
An Important Note: Do not stop imaging with the ESYNC signal high. If the EXSYNC signal is high when
imaging stops an imaging artifact will remain on the next line.

The camera ships in internal sync, internal programmed integration (exposure mode 2).
EXSYNC (Triggers Line Readout)
Line rate can be set internally using the serial interface. The external control signal EXSYNC is optional and
enabled through the serial interface. This camera uses the falling edge of EXSYNC to trigger line readout.
Section 3.2 Exposure Mode and Line Rate details how to set frame times, exposure times, and camera modes.
Output Signals, Camera Link
These signals indicate when data is valid, allowing you to clock the data from the camera
to your acquisition system. These signals are part of the Camera Link configuration and
you should refer to the Camera Link Implementation Road Map, available here, for the
standard location of these signals.
Clocking Signal
Indicates
LVAL (high)
Outputting valid line
DVAL (high)
Valid data
STROBE (rising edge)
Valid data
FVAL (high)
Outputting valid frame
IMPORTANT:
This camera’s data
should be sampled on
the rising edge of
STROBE.

tLINE PERIOD
(t LP)
The minimum and maximum line times made up of tTransfer, tREADOUT
plus tOVERHEAD to meet specifications.
53,190 (12k)
106,382 (8k)
tTransfer
The time from the reception of the falling edge of EXSYNC to the rising edge
of LVAL when pretrigger is set to zero. Pretrigger reduces the number of
clocks to the rising edge of LVAL but d oesn’t change the tim e to the first
valid pixel. If the fixed integration time mode of operation is available and
selected then the integration time is added to the specified value.

tREADOUT
Is the number of pixels per tap times the readout clock period. Pretrigger = 0.
38,400 (12k)
25,600 (8k)
tOVERHEAD
Is the number of pixels that must elapse after the falling edge of LVAL
before the EXSYNC signal can be asserted. This time is used to clamp the
internal analog electronics
425±25
thPR
Applies when the PRIN exposure control feature is enabled . The PRIN
signal must be held a minimum time after the EXSYNC falling edge to avoid
losing the integrated charge
Don’t care
twPR_LOW
Minimum Low time to assure complete photosite reset
3,000
tPR_SET
The nominal time that the photo sites are integrating. Clock synchronization
will lead to integration time jitter, which is shown in the specification as +/ -
values. The user should command times greater than these to ensure proper
charge transfer from the photosites. Failure to meet this requirement may
result in blooming in the Horizontal Shift Register.

Software Interface: How to
Control the Camera
All camera features can be controlled through the serial interface. The camera can also be used without the
serial interface after it has been set up correctly. Functions available include:
Controlling basic camera functions such as gain and sync signal source
Flat field correction
Generating a test pattern for debugging
The serial interface uses a simple ASCII-based protocol and the PC does not require any custom software.
Note: The command set may have changed from previous camera models. Do not assume that commands
perform similarly to older cameras.
Serial Protocol Defaults
8 data bits
1 stop bit
No parity
No flow control
115,200 kbps baud rate
Camera does not echo characters
Command Format
When entering commands, remember that:
A carriage return <CR> ends each command.
A space or multiple space characters separate parameters. Tabs or commas are invalid parameter
separators.
Upper and lowercase characters are accepted
The backspace key is supported
The camera will answer each command with either <CR><LF> OK > or <CR><LF> Error xx: Error
Message > or Warning xx: Warning Message >. The > is used exclusively as the last character sent by the
camera.
