Camera Link Fiber-Optic Extender
FOXY
Camera Link
Fiber-Optic Extender
Description
Specifications
The Foxy fiber-optic extender allows
Camera Link connections to span distances
well beyond the typical limit of 10 meters.
Using one duplex LC-style fiber-optic cable,
the transmitter and receiver modules can be
separated by hundreds or thousands of
meters.
No user programming or special
considerations are required. The extender’s
operation is completely automatic and
absolutely transparent to the camera and
frame grabber.
Foxy supports Base mode at 66.5 MHz with
no exceptions. It is fully Camera Link
compatible and employs genuine National
Semiconductor Channel-Link components
for the camera and frame grabber
interfaces.
Bi-directional general purpose I/O are
provided in addition to the Camera Link
connection. These can be used, for
example, to control attendant equipment
(e.g. illuminator, motorized lens) or to extend
a PC serial port.
The transmitter and receiver modules are
housed in rugged aluminum enclosures and
each requires less than 4 Watts. The LC
fiber-optic cable is detachable at both ends.

Usage Instructions
Troubleshooting
Foxy is easy to install and use. No
programming or configuration is required.
The LEDs are helpful in diagnosing various
problems.
Step 1: Connect the transmitter to the
camera with a Camera Link compatible
cable. Secure the cable’s jack screws.
TX OK does not illuminate: Ensure that the
optical transceiver is properly installed. The
transceiver can be removed by
disconnecting the fiber-optic cable, lowering
the transceiver’s bail latch, and then pulling
the transceiver out of the module.
Step 2: Connect the receiver to the frame
grabber with a Camera Link compatible
cable. Secure the cable’s jack screws.
Step 3: Connect the modules with a
duplex LC-style fiber-optic cable. The fiberoptic cable connects to optical transceivers
within the modules. Note that the cable
attaches with an audible click.
Step 4: Connect the power supplies to the
extender modules.
Step 5: Power-on the system. Either
module may be powered-on first. Once both
are on they will automatically synchronize.
Synchronization does not depend on
Camera Link activity. Thus, the modules will
synchronize without an active camera or
frame grabber, or with either disconnected.
RX OK does not illuminate: Ensure that the
other module is powered and that the fiberoptic cable is properly attached. Check for
kinks or sharp bends in the fiber-optic cable.
Check for dirt on the ends of the fiber and
inside the optical transceivers.
Transmitter’s TX OK and RX OK illuminate
but transmitter’s CAM SYNC does not:
Check the camera’s Camera Link cable.
Ensure that the camera is powered and in
the proper mode of operation, and that the
frame grabber is supplying the proper
control signals to the camera.
All LEDs except the receiver’s CAM SYNC
LED illuminate: Cycle power to the
Extender modules.
LED Indicators
Each module has four LED status indicators.
Precautions
TX OK
This indicates that the module
is transmitting an optical signal.
Exercise electro-static discharge
precautions when handling the extender.
RX OK
This indicates that the module
is receiving an optical signal and is properly
synchronized with the other module.
Note that the modules will synchronize
without a frame grabber or camera attached.
Power-off equipment before making or
breaking connections.
CAM SYNC On the transmitter this
indicates the presence of a Camera Link
clock.
On the receiver this indicates that camera
data is being received.
POWER
This indicates the module is
powered-on.

The modules are identical in appearance.
Make sure to connect the transmitter to the
camera and the receiver to the frame
grabber.
Handle the optical elements carefully. Do
not kink or tightly bend the optical cable.
Keep dirt off the ends of the fiber and out of
the optical transceivers.

General Purpose I/O Usage
The figure below illustrates one channel of
the GP I/O circuit. There are four channels
total, two in each direction.
The opto-isolated interface allows electrical
isolation between the module and the user’s
equipment. However, if isolation is not
required, the output stage (GPOUTx) can be
powered by connecting Vopto to +3.3Vout
and GNDopto to GND. Similarly, GPINx can
be asserted by connecting GPIN_ANODE to
+3.3V and GPINx to GND.
The GP interface can be modified to allow
GPOUTx to signal the state of a Camera
Link CC bit. Contact Stride for more
information.
The +3.3Vout connection is an output from
the modules (100 mA max.). Note that the
Vin and GND connections are available on
both the General Purpose I/O and Power
connectors.
Do not connect to the unused pins.
