with CoaXPress(CXP) Interface
The Cheetah C5180, C4181, C4180, C5190, C4191, and C4190 CMOS cameras provide
exceptional video image quality with a CoaXPress® (CXP) output interface and
GenICam™compliant programming. The ruggedized cameras use advanced 25-, 16-, or
12-megapixel ON Semiconductor Python sensors, industrial grade components, and
superior processing power to produce high-resolution images, a range of frame rates,
low noise, and excellent near-infrared sensitivity. The cameras provide exceptional
durability and performance in the most demanding applications.

About the Cheetah Camera
General
The Cheetah Python series of cameras provide an imaging platform with the latest digital
technology and industrial grade components. They use CMOS imaging sensors and offer a
broad range of resolutions and frame rates. Cheetah cameras are available in both
monochrome and color.
The cameras in this manual are compatible with the CoaXPress (CXP) output interface. Use
your frame grabber’s GeniCam™ compliant software to configure your cameras. The
following table describes the C5180, C4181, C4180, C5190, C4191, and C4190 cameras
covered in this manual.

Cheetah CMOS cameras are advanced, high-resolution progressive scan cameras. They are
fully programmable and field upgradeable. Programmable functions include exposure control,
frame rate control, area of interest, subsampling, pixel averaging, gain, offset, triggering
options, strobes, output control, bad pixel correction, and user-programmable look-up tables
(LUT). The cameras use ON Semiconductor area scan Python CMOS image sensors and feature
a built-in processing engine, low noise characteristics, and optimized thermal distribution.
The Cheetah C5180, C4181, C4180, C5190, C4191, and C4190 cameras use global shutter
operation for exceptionally high frame rates and superior motion capture. The cameras can
control exposure time using internal controls or an external pulse width. They support
exposure times up to 1 second with 1 µs increments. An Area of Interest (AOI) can be
programmed for each acquisition frame, and subsampling or pixel averaging capabilities are
also available. The cameras also support analog gain up to 10 dB (3.17x) and allow further
expansion of the low-end signal with 24 dB (16x) of additional digital gain available.
Built-in gamma correction and user-defined look-up table (LUT) capabilities optimize the
camera’s dynamic range features. You can also apply defective pixel correction (DPC) and hot
pixel correction (HPC) 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 2-channel (C5180, C4181, C4180) or 4-channel (C5190, C4191, C4190)
CXP-6 CoaXPress output interface that includes 8-bit and 10-bit data transmission and camera
control functionality in one cable. There is also support of active or passive Canon EF lenses.
The camera’s ruggedized design and flexibility enable its use in a 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.

Technical Support
Imperx fully tests each camera before shipping. If the camera is not operational after power
up, check the following:
1. Check coaxial 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 it is not, refer to the section
2.3 LED Status Indicators.
3. Enable the test mode and verify that the communication between the computer
and the camera is established. If the test pattern is not present, power off the
camera, check all the cabling, software settings, and computer status.
4. If problems still exist, contact technical support at:

Hardware
Camera Back Panel
The Cheetah Python CXP cameras provide three connectors for outside equipment and one
status indicator LED on the back panel. The panel includes:
1. Two 75-ohm, 1.0/2.3 DIN mini-coax receptacles (Amphenol P/N 282121-75)
provide 2-channel data output, control data (including Canon lens control), trigger,
and power over CXP.
2. Male 12-pin Hirose type miniature locking receptacle #HR10A-10R-12PB(71)
provides the general purpose I/O interface.
3. USB type B programming/SPI connector.
4. Status LED indicates the status of the camera.
5. Serial Number shows camera model and serial number.

CXP Camera Connectors and
Cables
The coaxial cable(s) connected to the camera provides power over CXP (PoCXP). The
Camera’s video data output, control data, triggering, and general I/O’s are serialized and
continuously transmitted over CoaXPress (CXP-6) using a standard 75-ohm mini-coaxial
cable. Imperx offers two types of mini-coax cables: 1) a cable with a 1.0/2.3 DIN mini-coax
push/pull plug on one end and a BNC connector on the opposing end; 2) a cable with a
1.0/2.3 DIN mini-coax push/pull plug on both ends. The interface provides a high-speed
downlink up to 6.25 Gbps for video transport and a lower speed 20 Mbps uplink for
communication and control.
The CXP output interface requires a CoaXPress frame grabber for collecting and storing the
camera’s output. The frame grabber installs in the host computer and enables you to view
images and configure the camera.
I/O Cable
The optionally purchased PWIO01 cable is used for transmitting external trigger and strobe
signals. It terminates in a female HIROSE plug #HR10A-10P-12S(73) on one end and 12 loose
wires on the opposing (see Figure 2).
Figure 2: CBL-PWIO01 cable (ordered separately)

Cable for cameras with Canon Lens Control
If using Canon EOS active lens control with the camera, use CBL-IO12-0002 cable to connect
lens to the camera. The CBL-IO12-0002 cable is sold separately and used for transmitting
power, lens control, trigger input, and strobe output signals. It terminates in a female
HIROSE plug #HR10A-10P-12S(73) on one end and on a female Sam Woo and two BNC
connectors on opposing end (see Figure 3).

I/O Connector
A 12-pin Hirose type connector on the back of the camera provides all external input/output
signals supplied to the camera. The male Hirose connector is a miniature locking receptacle
#HR10A-10R-12PB(71).

Electrical Connectivity
Cheetah cameras have two external inputs: IN 1 and IN 2. Input IN1 is optically isolated
while input IN2 accepts low voltage TTL (LVTTL). Cheetah cameras provide two general-
purpose outputs. Output OUT1 is a 5 V TTL compatible signal and output OUT2 is opto-
isolated. The following graphics show the external input electrical connections and the
external output electrical connections.

August 27, 2019 Page 20 of 86 Rev 1.0
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 V and 24 V. The minimum input current is 3.3 mA.
Figure 5: 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 V) or TTL
(5.0 V). The total maximum input current must not exceed 2.0 mA.
Figure 6: IN2 electrical connection
C. Output OUT 1 – TTL
Output OUT1 is a 5 V TTL compatible signal and the maximum output current must not
exceed 8 mA.
Figure 7: 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 OUT 2 Contact
2 must not exceed 25 V and the current through the switch must not exceed 50 mA. On
resistance is less than 5 Ohms.
