2-2 Camera Link
Camera Link is a communication interface for use in a vision application development. In the
past, the camera manufacturer and Frame Grabber manufacturers use their own standard
connectors and cables. This has caused a lot of confusion and increased costs to users. In order to
eliminate this confusion and increase the data rate and data transmission trouble, the
specifications of Camera Link interface have been made to the regulations of cable or connector
assembly specifications, transfer speed, transfer method at the meeting of camera makers and
Frame grabber manufacturers.
Currently, many digital video solution use the LVDS (Low Voltage Differential Signal)
communication as defined RS-644. LVDS is a way to improve the existing RS-422 that had
intractable cable and transmission speed limit. RS-644 LVDS was the Camera Link standard. The
LVDS can be transferred the data at high speed using low voltage swing differential signal
Differential Signal. This is compared with the existing single-ended signal (Single-ended Signal)
using one of the lines, the differential signal transmits the signal using two complementary lines.
Such a transfer is characterized by excellent noise immunity, low power consumption, large in-
phase voltage transmission to refer only to the data transfer on the ground, however Single-
ended system is impossible.
Camera Link has multiple configuration with depending on the amount of data to be transferred.
Base Configuration consists of 28 bits, including a 24-bit pixel data and 3-bit video sync signal
lines of the Data Valid, Frame Line Valid, Line Valid, one reserved signal line, and can transmit
2.04Gbit / s (256MB / s). Medium Configuration can be transmitted the 48bit video signal to
4.08Gbit/s(510Mb/s), Full Configuration can be transmitted the 64bit video signal to
5.44Gbit/s(680MB/s). Camera Link requires two cables to transfer more than Medium
Specifications.
Transmitter part is converted to LVDS data stem’s 4/8/12 from 28/48/64 bit CMOS / TTL data
only. Converted signal is transmitted to MDR Cable in accordance with the Transmit Clock signal,
the opposite Receiver will be converted into parallel LVDS data of 28/48/64 bits of CMOS / TTL
according to the Receive Clock signal from 4/8/12 LVDS data. This Channel Link technology can
immediately take advantage of the low cost chip-set because easy to learn and easy to transplant.
Camera Link Interface includes Base Configuration, Medium Configuration, Full Configuration.
Base Configuration is used 4 RS-644 LVDS pairs for controlling the Transmitter/Receiver and
Camera like [Figure 2-2], is used for communication between the camera and the frame grabber.
Transferred the data from serial 26-Pin MDR Cable, is used to change 28-bit parallel image data at
the Receiver part of Frame Grabber.

2-3 Camera Link Cable & Connector
The connection between the camera link cameras and USB3-FRM13 board uses the 26 Pin Mini
MDR (Mini D Ribbon) cable. Camera Link cable consists of twin-axial shielded cable and 2 Mini
MDR 26-male plug. The bottom of [Figure 2-4] Camera Link cable is typically used.
26-Pin Mini MDR Connecter is located at the end of the cable as like [Figure 2-5], [Figure 2-6] is
26-Pin Mini MDR Connecter, placed at the Camera or Frame Grabber. As shown in the figure, Pin
numbers are cross-linked to each other, Transmitter and Receiver of Camera and Frame Grabber
signals are connected cross each other.

2-4 Camera Link & USB3-FRM13
USB3-FRM13 supports Camera Link Base/Medium/Full Configuration. Base Configuration, 24
data bits and four enable signals Frame Valid, Line Valid, Data Valid and a spare, including 28-bit
parallel signals serialized four LVDS signal lines and one LVDS signal line to fit the camera and
synchronous LVDS signal lines including four CC (Camera Control) signal and full 11 includes two
asynchronous serial communication to communicate with the camera LVDS lines, is transmitted
through one MDR cable. In order to use the MDR Medium / Full Configuration is used other cable
and has a total 64bit wide video path.
The transmitted signal parallelizes 12 video LVDS serial signals into 64-bit parallel video signals
and control signals for each specification (Frame Valid, Line Valid, Data Valid, and a spare) through
the Channel Link chip in USB3-FRM13. In addition, one LVDS to synchronize the signal between
the camera and the USB3-FRM13 makes a clock signal, and the remaining cameras control signals
and communication signals are converted into general TTL signal levels and used.

2-5 PoCL Function
PoCL (Power over Camera Link) is to transmit the power to the cable such as the data transfer
cable to the camera. [Figure 2-9] shows the connection with theUSB3-FRM13 and the camera.
(a) Base Configuration PoCL Connection
(b) Full Configuration PoCL Connection
Camera Link Signals Power, Other Control Signal
[Figure 2-9. PoCL Connections]
This concept is similar the USB-powered devices to receive power from a power source such
as a Repeater or Frame Grabber. PoCL has an advantage of reducing the number of interfaces
required by the back of the camera. That is, using the four drain of the Camera Link cable wires
(4 ground), the power cable can be removed from the camera. Not only it does not have any
effect the quality of data from the camera, but also it is very helpful in reducing the cost and size
of the system to remove the power source terminal.

USB3-FRM13 User’s Manual

[Figure 2-10. Connection without Power Cable]
Implementation of PoCL that is, power transfer is used by setting the Camera Link 1, 13, 14, 26
pins as [table 1] and 1 and 26pins are used as the power(+ 12V). It can supply current of 330mA
for 12V, it can supply current of 400mA for 10V as standard on 4W (watt),
For USB3-FRM13, PoCL function can be implemented in the Base Configuration Connector.
It is available for Base / Full Configuration camera.

[Figure 2-12. PoCL Cable Pin out]
In order to use a PoCL, generally it requires a transformation of the Frame Grabber (power
supply section) or a dedicated cable. Frame Grabber conversion is divided into the power by
changing the design of the product to include a power supply "safe power" or "dedicated power".
Difference between the two, in the case of of "safe power" is to add some of the sensor circuit in
order to detect the possible PoCL camera –it does not detect the camera and cable, there is no
power supply. "Dedicated power" is always supplied a power, but use a fuse in order to supply
the equipment that do not receive support.
USB3-FRM13 supports dedicated power. It is only available if the camera supports PoCL and
uses PoCL cables. If either the camera or the cable does not support PoCL, PoCL does not work.
If you do not want to use the PoCL of the camera while using the PoCL cable, disconnect the
fuse (F1) on the board.

The Line Scan Camera is less time to transfer the information rather than Area Scan
Camera because the outputs are a single line of pixels per exposure. However, the Line
Scan Camera will be required moving objects in order to obtain images. Synchronization
between the movements of the camera and the object is required. This synchronization is
a little difference according to the manufacture’s cameras and is performed by the trigger
pulse which most of the triggering signal of an external camera or the camera’s itself. The
trigger pulse is initiated by the application. A thickness, width, delay of the trigger can be
gave a value (Blank, Width, Delay) by the program.
