1. Introduction
1.1. Overview
The CLR-101B Camera LinkTM1Repeater supports applications requiring separation
between camera and frame grabber in excess of the maximum Camera LinkTM cable
length (10 meters).
One Camera LinkTM cable connects the camera to the CLR-101B, and a second cable
connects the CLR-101B to the frame grabber. This solution provides a 20 meter reach
between camera and frame grabber using a pair of standard 10m Camera LinkTM cables.
Up-to three repeaters may be cascaded to support greater distances. CLR-101B
incorporates high-speed 85MHz interfaces and is compatible with any Camera Link
“Base” configuration camera. “Medium” configuration applications are supported using
two repeaters in parallel.
Featuring a sturdy compact enclosure with mounting flange and locking power supply
connector, the CLR-101B is well suited for OEM and industrial applications.

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 CLR-101B is provided in Figure 1-1. The CLR-101B regenerates
the “base” configuration signal set defined in the Camera Link Specification. The
regenerated signals may then be transmitted an additional distance up-to 10 meters over
standard Camera LinkTM cables.
The CLR-101B incorporates the connectors, signals, pinouts, and chipset in compliance
with the Camera LinkTM specification. The CLR-101B regenerates all the “base”
configuration signals, consisting of video data, camera control, and serial communications.

The CLR-101B incorporates high-speed (85MHz) interfaces and is compatible with any
“base” configuration camera. “Medium” configuration applications are supported using a
pair of CLR-101B’s in parallel. The CLR-101B does not support the Camera Link “full”
configuration.
The CLR-101B is powered by an external wall plug-in power supply (optional). A
locking power supply connector reduces the risk of an accidental disconnect.

1.4. Typical Applications
1.4.1. Standard Base Application
A typical CLR-101B application is shown in Figure 1-2. A Camera LinkTM “base”
configuration camera is connected to the CLR-101B via a standard 10m Camera
LinkTM cable. A second 10m Camera LinkTM cable is then connected from the CLR-
101B to a Camera LinkTM frame grabber. This provides a 20 meter reach between
camera and frame grabber

1.4.2. 40 Meter Application
Figure 1-3 shows an application in which multiple CLR-101Bs and standard cables
are cascaded to provide a 40 meter separation between camera and frame grabber. In
this example, a 40 meter reach is achieved using three CLR-101Bs and four standard
10m Camera LinkTM cables.

1.4.3. Medium Application
CLR-101B medium application is shown in Figure 1-4. Medium configuration, in
which two cables connect the camera to the frame grabber, is supported using two
CLR-101B’s in parallel. A Camera LinkTM medium configuration camera is
connected to two CLR-101Bs via a pair of standard Camera LinkTM cables. A second
pair of cables is then used to connect the CLR-101Bs to the Camera LinkTM frame
grabber
