Table 1: Cheetah C5180, C4181, and C4180 overview.
Cheetah cameras are advanced, intelligent, high-resolution, progressive scan, fully
programmable and field upgradeable CMOS cameras. They are built around ON
Semiconductor area scan Python CMOS imagers and are feature rich with a built-in image
processing engine, low noise, and efficient and optimized internal thermal distribution.
The Cheetah cameras feature a wide range of programmable functions; including
exposure control, frame rate control, area of interest, subsampling, pixel averaging, gain,
offset, several triggering options, strobes, output control, transfer function correction,
temperature monitoring, and user programmable and up-loadable LUT.
All Cheetah cameras offer global shutter for superior motion capture and exceptionally
high frame rates in high throughput applications. Cheetah camera exposure time can be
controlled using an internal control or an external pulse width. Exposure times up to 1
second with 1µs increments are supported. An Area of Interest (AOI) can be programmed
for each acquisition frame, and subsampling or pixel averaging capabilities are also
available. Analog gains up to 10 dB (3.17x) are supported and digital gain controls allow
further expansion of the low-end signal with 24dB (16x) of additional gain available.
A built-in gamma correction and user-defined look-up table (LUT) capability optimizes the
camera’s dynamic range even further. Bad pixel correction (DPC) and hot pixel correction
(HPC) can also be applied to correct for pixels that are over-responding or under-
responding. Auto-White Balance (AWB) is available in color cameras to correct for color
temperature. The cameras have a Camera Link interface that includes 8/10/12 bit data
transmission with two, four, eight, or ten output taps as well as camera control all on one

or two cables. The cameras are fully programmable via the Camera Link interface. The
adaptability and flexibility of the camera allow it to be used in a wide and diverse range of
applications including machine vision, metrology high-definition imaging and surveillance,
medical and scientific imaging, intelligent transportation systems, aerial imaging,
character recognition, document processing and many more.

1.2 Cheetah Specifications
1.2.1 General Information
A CMOS camera is an electronic device for converting light into an electrical signal. The
camera contains a light sensitive element CMOS (Complementary Metal Oxide
Semiconductor) where an electronic representation of the image is formed. The CMOS
image sensor consists of a two-dimensional array of sensitive elements –silicon
photodiodes, also known as pixels. The photons falling on the CMOS surface create
photoelectrons within the pixels, where the number of photoelectrons is linearly
proportional to the light level. Although the number of electrons collected in each pixel is
linearly proportional to the light level and exposure time, the number of electrons varies
with the wavelength of the incident light.

Cheetah Python Camera with Camera Link –User Manual
March 23, 2018 Page 10 of 96 Rev 2.1
1.3.1.1 Global Shutter Description
All Cheetah cameras support global shutter readout mode. In Global Shutter (GS) mode
every pixel starts and stops integration at the same time. This mode is excellent for clean
capture of moving scenes without the need for a mechanical shutter. When global shutter
mode is used, all pixel data is stored in light shielded regions within each pixel and held
there until readout.
Figure 1: Global Shutter Description
1.3.1.2 A/D architecture and frame rate controls
The image sensors used by the C5180, C4181, and C4180 cameras multiplex 80 (C5180)
and 64 (C4181 and C4180) columns respectively into an array of 64 A/D converters. The
camera takes care of all the details of re-ordering the lines within frame grabber memory.
Unlike a CCD where digitization is performed within one-pixel time, these cameras
perform digitization at 1/64th the pixel rate (64 A/D converters) and the digitization has a
depth of 10 bits.
The image sensor provides up to 32 Low-voltage Differential Signaling (LVDS) outputs, and
the time to readout one line from the image sensor is much less than the time needed to
output the data using Camera Link. The camera compensates for this mismatch in data
output rate versus data capture rate using two methods: a variable pixel clock for line
readout and the ability to add 1 microsecond of delay (row overhead) time at the end of
each line output by the camera. Slowing down the pixel line clock and adding delay (dead
time) at the end of each line allow the Camera Link frame grabber to keep pace with the
camera output.
The following figures show a typical CMOS image sensor architecture and the image
sensor spectral response in monochrome and color.

Cheetah is available with Monochrome or Color CMOS imager. The color image sensor is
equipped with a set red, green, and blue color filters arranged in a Bayer pattern over the
pixels. Red is the starting color.

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:

2.1.1 Power Supply
The camera requires a 12-volt power supply. Imperx recommends purchasing the optional
Imperx PS12V04 power supply. The PS12V04A power supply also provides connectors for
trigger input (black) and strobe output (white).

2.2 Camera Power Connector
The male 12-pin Hirose connector provides power and all external input/output signals
supplied to the camera. Refer to the following tables for connector pin-outs and pin
mapping. The connector is a male HIROSE type miniature locking receptacle #HR10A-10R-
12PB (71). The optionally purchased power supply is shipped with a power cable that
terminates in a female HIROSE plug #HR10A-10P-12S (73).

2.2.2 Electrical Connectivity
The Cheetah has two external inputs: IN 1 and IN 2. Input “IN 1” is optically isolated, while
input “IN 2” accepts Low Voltage TTL (LVTTL). Cheetah provides two general purpose
outputs. Output “OUT 1” is a 5v TTL (5.0 Volts) compatible signal and output “OUT 2” is
opto-isolated. The following four figures show the external input electrical connections
and the external output electrical connections.

Cheetah Python Camera with Camera Link –User Manual
March 23, 2018 Page 20 of 96 Rev 2.1
A. Input IN 1- Opto-Isolated
The input signal “IN 1” and “IN 1 Rtn” are optically isolated and the voltage difference
between the two must be positive between 3.3 and 24 volts.
Figure 9: IN1 electrical connection.
B. Input IN 2 LVTTL
The input signals “IN 2” and “IN 2 Rtn” are used to interface to a TTL or LVTTL input signal.
The signal level (voltage difference between the inputs “IN 2” and “IN 2 Rtn”) MUST be
LVTTL (3.3 volts) or TTL (5.0 volts). The total maximum input current MUST NOT exceed 2.0
mA.
Figure 10:IN 2 electrical connection.
C. Output OUT 1 LVTTL
Output OUT 1 is a 5v TTL (5.0 Volts) compatible signal and the maximum output current
MUST NOT exceed 8 mA.
Figure 11:OUT 1 LVTTL electrical connection.
D. Output OUT 2 - Opto-isolated
Output OUT 2 is an optically isolated switch. There is no pull-up voltage on either contact.
The voltage across OUT 2 Contact 1 and OUT 2 Contact 2 MUST NOT exceed 25 volts and
the current through the switch MUST NOT exceed 50 mA.
