The CLV-402 Camera Link
two frame grabbers using standard Camera Link
addition of a second frame grabber for functions such as camera setup, secondary/parallel
processing, and monitoring.
One frame grabber acts as master (primary) and provides control and communications to
the camera. The secondary (slave) frame grabber receives camera video data only. The
CLV-402 incorporates high-speed 85 MHz interfaces and supports all Camera Link
configurations (base/medium/full). Multiple CLV-402s may be cascaded to support 4 or 8
frame grabbers.
The CLV-402 may also be used as a high-speed (85 MHz) repeater, doubling the
maximum distance between camera and frame grabber.
The CLV-402 Camera Link
well suited for industrial environments.

1.3. Functional Description
A block diagram of the CLV-402 is provided in Figure 1-1. The CLV-402 interfaces one
camera to two frame grabbers. One frame grabber is the master (primary), and one frame
grabber is slave (secondary). All video interfaces incorporate high-speed (85 MHz)
Channel Link devices.

CLV-402 Camera LinkTM Video Splitter
Figure 1-1: CLV-402 Block Diagram
The interface between the camera and the master frame grabber contains the entire
Camera Link
TM
signal set defined in the Camera Link Specification for all configurations
(base/medium/full). 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.

Page 6
Since the CLV-402 regenerates all signals, it also acts as a high-speed (85 MHz) repeater
and supports an additional 10 meters of separation between camera and frame grabbers(s)
using standard Camera Link
TM
cables.
The CLV-402 is powered by an optional external wall plug-in power supply.

1.4. Typical Applications
1.4.1. Standard Application
A standard CLV-402 application is shown in Figure 1-2. In this Camera Link
“full” configuration example, the camera is connected to a CLV-402 via a pair of
standard Camera Link
to connect the CLV-402 to the master and slave Camera Link
TM
cables. Four additional Camera LinkTM cables are then used
TM
frame grabbers.
TM
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.
“Medium” configuration applications use the same cable connections as shown for the
full case.
“Base” configuration applications require just one cable between camera and CLV402, and one cable from the CLV-402 to each of the frame grabbers. Only the
connectors marked “base” are used, the “full” connectors are not used.

Multiple CLV-402s may be cascaded to support four or eight frame grabbers. An
application in which three CLV-402s are cascaded to interface four frame grabbers to
a Camera Link
standard Camera Link
TM
“full” configuration camera is shown in Figure 1-3. Fourteen
TM
cables are used to interconnect the equipment. Note that one
frame grabber is the master, and all remaining frame grabbers are slaves.

2.3. Video Connector Signals
The MDR-26 video connector signal assignments comply with the Camera LinkTM “full”
configuration, providing compatibility with all Camera Link cameras and frame grabbers
(base, medium, and full). 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.
Tables 2-1 and 2-2 identify the signal assignments for the CLV-402 “Base” and
“Medium/Full” MDR-26 video connectors, respectively.

2.4. Cable Shield Grounding
Camera and frame grabber cable “outer” shields are connected to the CLV-402 aluminum
case. The case is isolated from the CLV-402 circuitry and the cable “inner” shields.
The frame grabber cable “inner” shield connects to circuit digital ground, maintaining
signal reference levels between the CLV-402 and the frame grabber.
The Camera Link
grabbers that enable the inner shields be tied to digital ground either directly, or through a
parallel R/C network. In CLV-402, the camera connector represents the Camera Link
TM
Specification recommends that a provision be incorporated into frame
TM
frame grabber interface. To incorporate this flexibility, the CLV-402 ties the inner shields
from the camera connector to digital ground through 0-ohm resistors. If necessary, the 0ohm resistors may be replaced with a parallel RC network.
