1. Introduction
PCIe-FRM11 is an image acquisition device that supports cameras compatible with Base
configuration camera Link. PCIe-FRM11 acquires images in real time and transfers them directly to
system memory. The easy installation method and fast image transfer make it a suitable device to
meet the needs of the industry with low cost and high efficiency.
The sample program provided by the DQ system is provided in the form of a source so that the API
provided to use the board can be tested briefly, so the user can modify it and use it. Refer to Chapter
5 Sample Program for detailed explanation.
The MDR 26-pin connector can be connected to a Camera Link compatible camera, and the Mini-
Circular connector can supply the camera's power (12V). In addition, it has the function of external
control by providing 8 Digital Inputs and 8 Digital Outputs. Refer to 3-3 Connector Pin-Out for
detailed explanation.
Camera-link This is a board that transmits the captured image frame to the PC through the PCI
Express 1x interface method in conjunction with the standard camera. The operation of the board is
controlled by the program API, and the figure below shows the interlocking operation of the board.
[Figure 1-1. PCIe-FRM11 Board Usage]
In [Figure 1-1], PCIe-FRM11 is installed in the PCI Express slot in the PC and receives from the
camera through the image frame through the Camera-Link standard interface. It is responsible for
transmitting the received data to the application program through the PCI Express 1x interface. It is
interfaced with external I/O through the 15Pin D-SUB connector on the left, and the mini-circular
connector in the middle can supply power to the camera, and the 26Pin MDR connector at the bottom
is connected to Camera-Link Camera to provide frame data and asynchronous (UART) to send and
receive communication data.

2-3 Camera Link
Camera Link is a communication interface developed for use in vision applications. In the past,
we used proprietary connectors and cables between camera makers and frame grabber makers.
This caused a lot of confusion and cost increase for users. In order to resolve this confusion,
increasing data rate, and confusion in data transmission, the specifications of the Camera Link
interface are the specifications of cable or connector assembly, transmission speed and It was
made with regulations such as transmission method.
Many digital video solutions today use Low Voltage Differential Signal (LVDS) communication
defined by RS-644. RS-644 LVDS has become the Camera Link standard by improving the existing
RS-422 method, which had inconvenient cables and limited transmission speed. LVDS can transmit
data at high speed by using a differential signal with a low voltage swing. Compared to the
existing single-ended signal using one line, the differential signal transmits the signal using two
complementary lines. This transmission structure has the characteristics of large-scale common-
phase voltage rejection, low power consumption, and excellent noise immunity, which is
impossible with single-ended systems that only reference ground for data transmission.
An advanced LVDS technology for the transmission of digital data is a Channel Link. The channel
link can transmit parallel-to-serial and serial-to-parallel at 2.38 Gbps. Referring to [Figure 2-3], the
transmitter converts 28-bit CMOS/TTL data into 4 LVDS data streams. The converted signal is
transmitted to the MDR cable according to the Transmit Clock, and the opposite receiver converts
these four LVDS data into a 28-bit CMOS/TTL parallel signal according to the Receive Clock. This
channel link technology is being used as a low-cost chipset that is easy to learn and portable, so
that it can be used immediately.
Camera Link interface includes Base Configuration, Medium Configuration, and Full
Configuration. Base Configuration uses four RS-644 LVDS pairs for transmitter/receiver and camera
control as shown in [Figure 2-3], and uses two RS-644 LVDS pairs for communication between
camera and frame grabber. The data transmitted serially through the 26-Pin MDR Cable is
changed to 28-bit parallel image data at the Receive end of the frame grabber and used.

2-4 Camera Link Cable & Connector
Camera Link The connection between the camera and the PCIe-FRM11 board uses a 26 Pin
MDR (Mini D Ribbon) cable. The camera link cable consists of a twin-axial shielded cable and two
MDR 26-male plugs. [Figure 2-4] below is a commonly used camera link cable.
[Figure 2-5] is a 26-Pin Male MDR Connecter located at both ends of the cable, and [Figure 2-6]
is a 26-Pin Female MDR Connector, located at the camera or frame grabber. As shown in the
figure, the pin numbers are cross-connected, so that the transmitter and receiver terminals of the
camera and frame grabber signal lines are cross-connected.

2-5 Camera Link & PCIe-FRM11
PCIe-FRM11 supports Camera Link Base Configuration. Base Configuration consists of 4 LVDS
signal lines serializing 28-bit parallel signals including 24 data bits and 4 enable signals Frame
Valid, Line Valid, Data Valid, and a spare, and 1 LVDS signal line to synchronize with the camera. ,
Asynchronous serial communication including 4 CC (Camera Control) signals and 2 LVDS lines for
asynchronous serial communication to communicate with the camera are transmitted through
MDR cables.
The transmitted signal deserilizes 4 video LVDS serial signals into 28-bit parallel video signals
and control signals (Frame Valid, Line Valid, Data Valid, and a spare) through the Channel Link chip
in PCIe-FRM11. In addition, a clock signal is made with one LVDS to synchronize the signal
between the camera and PCIe-FRM11, and the remaining cameras control signals and
communication signals are converted into general TTL signal levels and used.
