1. Introduction
1.1. Overview
The CLR-102 Camera Link1Repeater supports Power over Camera Link (PoCL)
applications requiring separation between camera and frame grabber in excess of the
maximum Camera Link cable length (10 meters).
One Camera Link cable connects the camera to the repeater, and a second cable connects
the repeater to the frame grabber. This solution provides a 20 meter reach between camera
and frame grabber using a pair of 10m Camera Link cables. Several repeaters and cables
may be cascaded to support greater distances.
The CLR-102 powers PoCL cameras and incorporates the PoCL SafePower feature. The
CLR-102 is also an adapter; enabling the use of PoCL cameras with either PoCL or
standard (non-PoCL) Camera Link frame grabbers. PoCL frame grabbers used with
the CLR-102 must have the SafePower feature.
CLR-102 incorporates high-speed 85MHz interfaces and is compatible with both PoCL
and standard (non-PoCL) ”base” configuration cameras. The CLR-102 incorporates the
Miniature Camera Link (miniCL) connector popular with PoCL devices.
The CLR-102 is housed in a sturdy, compact aluminum enclosure.
1The Camera Link interface standard enables the interoperability of cameras and frame grabbers,
regardless of vendor. The Automated Imaging Association (AIA) sponsors the Camera Link
program including the oversight Camera Link Committee, the self-certification program, and the
product registry. The Camera Link specification may be downloaded from the AIA website, found
at www.machinevisiononline.org

1.3. Functional Description
A block diagram of the CLR-102 is provided in Figure 1-1. The CLR-102 regenerates the
“base” configuration signal set defined in the Camera Link Specification for Power over
Camera Link (PoCL) applications. The regenerated signals may then be transmitted an
additional distance up-to 10 meters over Camera Link cables. The CLR-102 incorporates
the Miniature Camera Link (miniCL) connector widely used in PoCL devices.
The CLR-102 incorporates the connectors, signals, pinouts, and chipset in compliance
with the PoCL section of the Camera Link specification. The CLR-102 regenerates all the
“base” configuration signals, consisting of video data, camera control, and serial
communications. A front-panel link status indicator identifies an active camera
connection.
The Camera Link Specification requires that repeater devices used in PoCL applications
“power” the camera, not simply pass-through power from the frame grabber to the
camera. To meet this requirement, The CLR-102 incorporates the 12V powering circuitry
specified. The 12V powering circuitry includes filtering as well as over current protection.
The over current protection is in the form of an automatically resetable fuse.
The CLR-102 incorporates the SafePower feature defined in the PoCL section of the
Camera Link Specification. The SafePower feature allows the CLR-102 to safely
interoperate with either PoCL or standard (non-Pocl) cameras and cables by first sensing
and identifying the attached camera type (PoCL or standard), and then only providing
power to PoCL cameras. This avoids excessive current draw and possible damage to the
CLR-102 caused when attempting power a standard (non-PoCL) camera and/or cable.
Since the CLR-102 provides power to PoCL cameras, it is not required that the frame
grabber connected to the CLR-102 be PoCL. Therefore, the CLR-102 acts as both a
repeater (for increasing distance between PoCL camera and frame grabber), and an
adapter (for enabling the use of PoCL cameras with standard non-PoCL Camera Link
frame grabbers).
PoCL frame grabbers used with the CLR-102 must have the SafePower feature.

The CLR-102 incorporates the Miniature Camera Link (miniCL) connector widely used in
PoCL cameras and frame grabbers. miniCL cables as well as adapting cables (i.e. one end
standard MDR style, one end miniCL) are readily available from Camera Link cable
suppliers.
The CLR-102 adds minimal delay (i.e. latency) to the video data path. This is an
important criterion for time-critical applications. The latency through the CLR-102 is a
fixed 3 pixel-clock delay. The pixel clock is established by the camera and can range from
20-85 MHz. Therefore, the CLR-102 fixed delay can range from 35 to 150 nS, depending
on camera. The delay added by the CLR-102 for the camera control and serial
communication signals is under 5 nS.
The CLR-102 detects the presence of an active Camera Link camera. When an active (i.e.
powered) camera is detected, the front-panel “link” indicator illuminates. The front panel
also includes a power indicator to show that the CLR-102 is powered.
The CLR-102 is powered by an external multi-nation wall plug-in power supply. The
locking power supply connector reduces the risk of an accidental disconnect.
For information about PoCL and SafePower, please see the Camera Link Specification.

1.4. Typical Applications
1.4.1. PoCL Repeater Application
A typical CLR-102 repeater application is shown in Figure 1-2. A PoCL camera is
connected to the CLR-102 using a PoCL-compatible Camera Link cable. The
connectors on the CLR-102 are miniCL type. If the camera has a miniCL connector,
then a PoCL cable with miniCL connectors at both ends is used. If the camera uses
the larger MDR connector, then a PoCL cable with one end miniCL and one end
MDR is used. Similarly, the appropriate cable is used to connect the PoCL frame
grabber to the CLR-102. Note that the cable between the CLR-102 and the frame
grabber can be either standard camera link or PoCL type, although the standard type is
recommended. The PoCL frame grabber must have the SafePower feature.
Camera power is provided by the CLR-102. If 10m cable lengths are used, then this
solution provides a 20 meter reach between camera and frame grabber.

1.4.2. PoCL Adapter Application
A typical CLR-102 adapter application is shown in Figure 1-3. A PoCL camera is
connected to the CLR-102 using a PoCL-compatible Camera Link cable. The
connectors on the CLR-102 are miniCL type. If the camera has a miniCL connector,
then a PoCL cable with miniCL connectors at both ends is used. If the camera uses
the larger MDR connector, then a PoCL cable with one end miniCL and one end
MDR is used. Similarly, the appropriate cable is used to connect the standard (non-
PoCL) frame grabber to the CLR-102. Note that the cable between the CLR-102 and
the frame grabber can be either standard camera link or PoCL type, although the
standard type is recommended.
Camera power is provided by the CLR-102. If 10m cable lengths are used, then this
solution provides a 20 meter reach between camera and frame grabber.
