1 About the Camera
1.1 General
The Cheetah C2020, C2420, C2420Z, C4020, and C4120 CMOS cameras feature advanced
Sony Pregius CMOS image sensors, global shutter technology, and Camera Link interface
to produce high quality images with fast frame rates in a small form factor for industrial
application. The cameras ship with Imperx CamConfig programming software featuring an
easy-to-use graphical user interface (GUI).
The cameras in this manual support Camera Link Base, Medium, and Full connectivity for
reliability and high frame rates. Power over Camera Link (PoCL) capability is provided to
minimize cabling. Camera Link cameras require a frame grabber on the computer for
capturing individual frames from the camera’s video stream.
The manual describes the cameras listed in the following table.

The C2020, C2420, C2420Z, C4020, and C4120 are small profile, progressive scan digital
cameras. They are fully programmable and field upgradeable. The cameras feature a built-
in image-processing engine, low power consumption, low noise, and high dynamic range
(71 dB). The cameras provide several trigger modes and output strobes allowing you to
synchronize the image capture of one or more cameras to an external event. They also
provide Area of Interest (AOI) and programmable look-up tables (LUT).
The C2420Z camera features a micro-polarized CMOS sensor. The sensor has
a 2x2 pixel sub-array where each pixel within the sub-array blocks a different polarization
filter angle (0, 45, 90 or 135 degrees). The camera’s 2462 x 2056 resolution provides
resolution of 1232 x 1028 per polarization angle.

such as machine vision, industrial inspection, high-definition surveillance, aerospace, and
more.

1.4 Technical Support
Each camera is fully tested before shipping. If for some reason the camera is not
operational after power up, check the following:
1. Check the power supply and all I/O cables. Make sure that all the connectors are
firmly attached.
2. Check the status LED and verify that it is steady ON, if not –refer to the LED
section.
3. Enable the test mode and verify that the communication between the frame
grabber and the camera is established. If the test pattern is not present, power
off the camera, check all the cabling, frame grabber settings, and computer
status.
If you still have problems with the camera operation, contact technical support at:

2 Hardware
2.1 Camera Connectivity
The back panel of the camera provides all the connectors needed to operate and control
the camera. The back panel also provides an LED status indicator.
Figure 1: CLF camera back panel connectors.
The camera provides the following connectors:
1. Two camera outputs. These are standard Mini-Camera Link connectors providing
data, sync, control, and serial interface.
2. Male 12-pin Hirose miniature locking receptacle #HR10A-10R-12PB (71)
providing power and I/O interface.
3. Status LED indicating the status of the camera (2.1.2. Camera LED Status).
4. Model / Serial Number showing the camera model and serial number.
2.1.1 Pin Assignments
The Hirose connector on the camera’s back panel is a male type miniature locking
receptacle #HR10A-10R-12PB(71). The Imperx power supply (sold separately) terminates in
a female HIROSE type miniature locking receptacle #HR10A-10P-12S(73) and has two small
BNC pig-tail cables for the external trigger input (black) and strobe output (white) (Table 1).

2.1.2. Camera LED Status Indicators
The camera has a red-green-yellow LED on the back panel of the camera. The following LED
colors and light patterns indicate the camera status and mode of operation:
LED Condition
Status Indication
Green steady ON
Normal operation. You should see a normal image coming out
of the camera.
Green blinks at
~ 2.0 Hz
Programmable Frame Time enabled.
Amber steady ON
Test mode. You should see one of the test patterns.
Amber blinks at ~ 0.5 Hz
Camera is in AGC/AEC mode or trigger mode. In this AGC/AEC
mode, changing the shutter slider does not affect image
luminance.
Red steady ON
RS-232 communication error or firmware load error. Re-
power the camera and load the factory settings. If the
condition is still present, contact the factory for support.
LED OFF
Power not present. Possible power supply failure or faulty
external AC adapter. Re-power camera and load factory
settings. If the LED is still OFF, contact the factory for RMA.
Table 2: LED status indicators on camera.
2.1.3 Power Supply
The camera can use an external power supply providing +12VDC, ± 10% and up to 2.5A DC
current. Imperx offers the PS12V04A universal power supply adapter for use with all
Camera Link cameras. The PS12V04A power supply ships with a power cable that

Cheetah Pregius Camera with Camera Link –User Manual

2.2 Electrical Connectivity
The Cheetah camera has two external inputs, IN 1 and IN 2. Input IN1 is optically isolated
while input IN2 accepts low voltage TTL (LVTTL). The camera provides two general-
purpose outputs. Output OUT1 is a 5v TTL (5.0 Volts) compatible signal and output OUT2
is opto-isolated. The following figures show the external input electrical connections and
the external output electrical connections:
A. Input IN 1- Opto-Isolated
Input signals IN1 and IN1 Rtn are optically isolated, and the voltage difference between
the two must be positive between 3.3 and 24 volts.
Figure 4: IN1 electrical connection.
B. Input IN 2 LVTTL
Input signals IN2 and IN2 Rtn provide interfaces to a TTL or LVTTL input signal. The signal
level (voltage difference between the inputs IN2 and IN2 Rtn) must be LVTTL (3.3 volts) or
TTL (5.0 volts). The total maximum input current must not exceed 2.0 mA.
Figure 5: IN2 electrical connection.
C. Output OUT 1 LVTTL
Output OUT1 is a 5v TTL (5.0 Volts) compatible signal and the maximum output current
must not exceed 8 mA.

Figure 6: OUT1 LVTTL electrical connection.
D. Output OUT 2 –Solid state relay, optically isolated
Output OUT2 is an optically isolated switch. There is no pull-up voltage on either contact.
External pull-up voltage of up to 25 volts is required for operation. Output is not polarity
sensitive. AC or DC loads are possible. The voltage across OUT2 Contact 1 and OUT2
Contact 2 must not exceed 25 volts and the current through the switch must not exceed
50 mA. On resistance is less than 5 Ohms.

2.3 Mechanicals
The camera housing is made of precision-machined aluminum. For maximum flexibility,
the camera has eight M3X0.5mm mounting holes located towards the front of the camera
on all four sides. An additional plate with ¼-20 UNC (tripod mount) and hardware ship
with each camera.
