5.3 Camera Block Diagram
Figure 5.1 Camera Block Diagram
All controls and data processing of the VP-61MX-18 H camera are carried out in one FPGA chip. The FPGA
generally consists of a 32-bit RISC Micro-Controller and Processing & Control logic. The Micro-Controller
receives commands from the user through the CoaXPress interface and then processes them.
The Processing & Control logic processes the image data received from the CMOS image sensor and then
transmits data through the CoaXPress interface. The Processing & Control logic also controls time-sensitive
trigger inputs and output signals. Furthermore, Flash and DDR3 are installed outside FPGA. The DDR3 is used
for the frame buffer to process images and the Flash stores the firmware to operate the Micro-Controller.

5.5.1 Camera Mounting and Heat Dissipation
Camera Mounting Recommendations for Antivibration
When you mount a camera in a poor condition, the fan equipped on the camera may amplify vibrations which
can lead to blurry images. Follow the instructions below to prevent and/or reduce vibrations caused by the fan.
Fix the camera’s front or side surface by using at least four screws.
Prevent ingress of foreign objects between the camera and system surfaces.
Keep the camera’s center of gravity as near as possible to the system’s center of gravity.
If your lens’ weight or size is greater than the camera’s, make and use proper mounting brackets to support
the lens.
Prevent foreign matters from falling into the fan. This may cause damage to the fan blades.
Camera Mounting Recommendations for Effective Heat Dissipation
Do not obstruct the air inlets and outlets of the fan.
If the fan is not available, leave enough space around the heat sink so that heat can be easily dissipated
through the heat sink by natural convection.
If the fan is not available, mount the camera on a metal structure made of high thermal conductive materials
(e.g. Aluminum) to properly dissipate the heat generated by the camera.
The contact surface of the camera must be at least 30% of the camera’s Front-Block.

6 Connecting the Camera
The following instructions assume that you have installed a CoaXPress Frame Grabber (hereinafter ‘CXP Frame
Grabber’) in your computer including related software. The procedure below also assume that you may attempt
to configure a link between a camera and CXP Frame Grabber by using four coax cables. For more detailed
information, refer to your CXP Frame Grabber User Manual.
To connect the camera to your computer, follow the steps below:
1. Make sure that the power supply is not connected to the camera and your computer is turned off.
2. Plug one end of a coax cable into the CH1 of the CXP connector on the camera and the other end of the
coax cable into the CH1 of the CXP Frame Grabber in your computer. Then, connect the CH2, CH3 and
CH4 of the CXP connector on the camera to the CH2, CH3 and CH4 of the CXP Frame Grabber
respectively using the other three coax cables.
3. Connect the plug of the power adapter to the 6-pin power input receptacle on the camera.
4. Plug the power adapter into a working electrical outlet.
5. Verify all the cable connections are secure.
You must connect the CH1, CH2, CH3 and CH4 of the CXP connectors on the camera to
their respective connectors on the CXP Frame Grabber using four coax cables.
The VP-61MX-18 H camera does not support Power over CoaXPress (PoCXP).

6.1 Precaution to Connect the CXP Cables
External or system vibrations may result in loosening or disengagement of the CXP cables from the CXP DIN
connectors. Vieworks recommends that you make a connector locking bracket for your application or use a
dedicated locking bracket (available from Vieworks, sold separately) for securing the cables to the CXP DIN
connectors.
6.2 Precaution to Center the Image Sensor
Users do not need to center the image sensor as it is adjusted as factory default settings.
When you need to adjust the center of the image sensor, please contact your local dealer or the
manufacturer for technical assistance.
6.3 Precaution about Blurring Compared to the Center
Users do not need to adjust the tilt as it is adjusted as factory default settings.
If the tilt settings need to be adjusted inevitably, please contact your local dealer or factory representative for
technical support.
6.4 Installing Vieworks Imaging Solution
You can download the Vieworks Imaging Solution at http://www.vieworks.com. You should perform the software
installation first and then the hardware installation.

7 Camera Interface
7.1 General Description
As shown in the following figure, three types of connectors and an LED indicator are located on the back of the
camera and have the functions as follows:
① Status LED: displays power status and operation mode.
② 6 pin Power Input Receptacle: supplies power to the camera.
③ 4 pin Control I/O Receptacle: provides access to the camera’s I/O lines.
④ CoaXPress Connector: transmits video data and controls the camera.

VP-61MX-18 H
Page 20 of 82 D-21-355
7.2 CoaXPress Connector
CoaXPress protocol includes an automatic link detection mechanism (Plug and Play) to correctly detect the
camera to the CXP Frame Grabber connection. The connection between the camera and CXP Frame Grabber
uses a coax (also known as ‘coaxial’) cable and provides up to 6.25 Gbps bit rate per cable.
7.2.1 CoaXPress Connector (75 Ω DIN 1.0/2.3 Receptacle)
Figure 7.2 CoaXPress DIN 1.0/2.3-type Connectors
The CoaXPress connectors on the VP-61MX-18 H camera comply with the CoaXPress standard and the
following table shows the channel assignments.

Table 7.1 Channel Assignments for CoaXPress Connectors
When you connect a camera to a CXP Frame Grabber using coax cables, make sure to
connect the cables to their correct channels. If you connect the CH1 of the CXP connector on
the camera to a channel other than CH1 of the CXP Frame Grabber, the camera may not
transmit images properly or the communication between the computer and camera may fail.
