1. Introduction
1.1. Overview
Designed for multi-camera systems, the CLV-403 Camera Link1Video Splitter interfaces
two Camera Link cameras to two frame grabbers each using standard Camera Link cables.
This enables the use of secondary frame grabbers for applications requiring parallel or
distributed processing, monitoring, etc. One frame grabber acts as master and provides
control and communications to the camera. The second frame grabber receives camera
video data only.
The CLV-403 incorporates high-speed 85 MHz interfaces and supports Camera Link base
configuration cameras. The CLV-403 also acts as a repeater, doubling the maximum
distance between the cameras and the frame grabbers.
Housed in a sturdy, compact aluminum enclosure, the CLV-403 Camera Link Video
Splitter is well suited for industrial environments.
1The Camera LinkTM interface standard enables the interoperability of cameras and frame grabbers,
regardless of vendor. The Automated Imaging Association (AIA) sponsors the Camera LinkTM
program including the oversight Camera Link Committee, the self-certification program, and the
product registry. The Camera LinkTM specification may be downloaded from the AIA website,
found at www.machinevisiononline.org

1.3. Functional Description
A block diagram of the CLV-403 Camera Link Video Splitter is provided in Figure 1-1.
The CLV-403 features two independent base-configuration splitters in a single unit for
multi-camera systems.
Each splitter interfaces one camera to two frame grabbers using standard Camera Link
cables. One frame grabber is the master (primary), and one frame grabber is slave
(secondary).
The interface between the camera and the master frame grabber contains the entire
Camera Link signal set defined in the Camera Link Specification for “base”
configurations. This consists of video data, camera control, and serial communications.
The master frame grabber receives video data from the camera, and can also control and
communicate with the camera.
The interface between the camera and the slave frame grabber contains only the video data
signals. The slave frame grabber receives video data, but cannot control or communicate
with the camera.
Since the CLV-403 regenerates all signals, it also acts as a repeater and supports an
additional 10 meters of separation between the cameras and the frame grabbers.
The CLV-403 is powered by an external wall plug-in power supply.

1.4. Typical Applications
1.4.1. Standard Base Application
A typical CLV-403 base application is shown in Figure 1-2. Two independent
Camera Link base configuration cameras are connected to a single CLV-403 via
standard Camera Link cables. Additional Camera Link cables are then used to
connect the CLV-403 to master and a slave frame grabbers for each camera.
The master frame grabbers provide camera control and communications, and may
also perform processing functions. The slave frame grabbers cannot control or
communicate with the cameras, but may be used for parallel processing, secondary
processing, camera setup, monitoring, etc.

2. Interface
2.1. Front Panel Connections
The CLV-403 Camera Link Video Splitter front panel is shown in Figure 2-1. The front
panel contains four video connectors for connecting to the cameras and to the master
frame grabbers. The front panel also includes a power indicator.
The video connectors are 3M MDR-26 types as specified in the Camera Link Spec.
Figure 2-2 identifies the MDR-26 pin positions.

2.3. Camera Connector Signals
The MDR-26 video connector signal assignments comply with the Camera Link “base”
configuration. The camera connector signal assignments correspond to the frame grabber
interface defined in the Camera Link Specification. Conversely, the frame grabber
connector assignments are as defined for the camera interface in the Camera Link
Specification. This arrangement provides compatibility with standard Camera Link
cables.
Table 2-2 identifies the signal assignments for the MDR-26 video connectors.
2.3.1. Cable Shield Grounding
Camera and frame grabber cable “outer” shields are connected to the CLV-403
aluminum case. The case is isolated from the CLV-403 circuitry and the cable
“inner” shields.
The frame grabber cable “inner” shield connects to circuit digital ground, maintaining
signal reference levels between the CLV-403 and the frame grabber.
