1. Introduction
1.1. Overview
The CLV-401 Camera LinkTM1Video Splitter interfaces one Camera LinkTM camera to
two frame grabbers using standard Camera LinkTM cables. This arrangement enables the
addition of a second frame grabber for functions such as camera setup, secondary/parallel
processing, and monitoring.
One frame grabber acts as master (i.e. primary) and provides control and communications
to the camera. The secondary (slave) frame grabber receives camera video data only. The
CLV-401 supports the Camera LinkTM “base” configuration. “Medium” configuration
applications are supported using two CLV-401s. Multiple CLV-401s may be cascaded to
support 4 or 8 frame grabbers.
The CLV-401 Camera Link TM Video Splitter is housed in a sturdy, compact aluminum
enclosure and 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-401 is provided in Figure 1-1. The CLV-401 interfaces one
camera to two frame grabbers. One frame grabber is the master (primary), and one frame
grabber is slave (secondary).

Figure 1-1: CLV-401 Block Diagram
The interface between the camera and the master frame grabber contains the entire
Camera LinkTM 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-401 regenerates all signals, it also acts as a repeater and supports an
additional 10 meters of separation between camera and frame grabbers(s) using standard
Camera LinkTM cables.
The CLV-401 is also compatible with the second Camera LinkTM cable used in the
“medium” configuration, enabling a pair of CLV-401s to be used in parallel to support
medium configuration applications.
The CLV-401 is powered by an external wall plug-in power supply.

1.4. Typical Applications
1.4.1. Standard Base Application
A standard CLV-401 base application is shown in Figure 1-2. A Camera LinkTM base
configuration camera is connected to a single CLV-401 via a standard Camera LinkTM
cable. Two additional Camera LinkTM cables are then used to connect the CLV-401
to the master and slave Camera LinkTM frame grabbers.
The master frame grabber provides camera control and communications, and
performs the primary processing functions. The slave frame grabber cannot control or
communicate with the camera, but may be used for parallel processing, secondary
processing, camera setup, monitoring, etc.

1.4.2. Medium Application
A CLV-401 medium application is shown in Figure 1-3. Medium configurations, in
which two cables connect the camera to the frame grabber, are supported using two
CLV-401s in parallel. A Camera LinkTM medium configuration camera is connected
to two CLV-401s via a pair of standard Camera LinkTM cables. Four additional
Camera LinkTM cables are then used to connect the CLV-401s to the master and slave
Camera LinkTM frame grabbers.

1.4.3. Cascaded Application
Multiple CLV-401s may be cascaded to support four or eight frame grabbers. An
application in which three CLV-401s are cascaded to interface four frame grabbers to
a Camera LinkTM base configuration camera is shown in Figure 1-4. Seven standard
Camera LinkTM cables are used to interconnect the equipment. Note that one frame
grabber is the master, and all remaining frame grabbers are slaves.
