Introduction
Smith & Nephew 450P and 460P 3-CCD CCUs
(Camera Control Units) are state-of-the-art video
CCUs designed for use in endoscopic surgical
applications. Fingertip control of camera features
(enhancement features and zoom capabilities
[460P camera only]) and accessories (VCRs,
video printers, and still image recorders)
maximize surgeon control over the visualization
system and documentation.
The 450P and 460P CCUs’ advanced 3-CCD
digital circuitry provides superior color rendition
and high-resolution images. Their advanced
automatic features offer enhanced ability to
customize Smith & Nephew cameras to meet
individual procedural requirements. The 450P
and 460P CCUs offer optimum light sensitivity
to ensure sufficient light output at all times in
various endoscopic surgical applications. Their
improved camera shutters allow for smoother
light compensation. Variable controls such as
automatic shutter settings and light adjustments
permit adaptation of the CCU to address
changing conditions during surgery. The
enhancement control gives you the ability to
enhance the contrast and edges of anatomical
features. The digital zoom feature provides visual
access to surgical sites previously difficult to
visualize.
The 460P CCU incorporates four digital output
ports: IEEE-1394 DV (digital video), SDI (serial
digital interface), and two DVI (digital visual
interface) ports. The IEEE-1394 port allows direct
connection with any accessory compatible with
DV format. The SDI port allows high-quality
video to be distributed up to 300 feet using a
single coaxial cable. The DVI ports allow high-
resolution video to be directly displayed on a
1280 x 1024 pixel digital flat panel display.

Prepare the Camera Head
Sterilize and disinfect the camera head following
the Cleaning and Sterilization procedure
enclosed with the camera head. Once this is
complete, remove the cap from the camera
cable connector and ensure that no moisture
remains on the camera cable connector pins.
Let the pins air dry if they are damp.
Inspect the System
Components
This inspection ensures optimal performance
as well as safe operation of the equipment.
Light Source
Verify that the light source is producing the
correct amount of light. Factors that can affect
the light output include:
• Improper bulb placement
• Blown fuses and/or thermocouples
• Worn-out or burned-out bulbs
Refer to the manufacturer’s Operations Manual
if you suspect problems with the light source.
Electrical Connections
Examine the electrical connections:
• Electrocautery and other electrical noise-
inducing medical equipment can interfere
with the performance of camera control units
and monitors. To prevent interference, plug
monitors and camera equipment into an
outlet on a wall separate from noise-inducing
equipment.
• Check that the electrical equipment is
properly grounded (i.e., plugs contain a
ground prong). The camera must be plugged
into a hospital-grade AC outlet.
• If the monitor has a termination switch, it
needs to be set to 75 Ω(ohms). If two or
more monitors are used, only the termination
switch on the last monitor needs to be ON.
• Double check the equipment setup diagrams
to ensure that all connections are correct.

Preoperative Setup (continued)
Cable Connectors
The 450P and 460P CCUs use the following types of
cables: BNC coaxial cables, S-VHS cables which
have a 4-pin mini-DIN connector, IEEE-1934
connectors, DVI connectors, and USB 2.0 style
connectors. Figure 5 explains how to use these
video cable connectors.
Figure 5. Video Cable Connectors

Smith & Nephew 450P and 460P 3-CCD Camera Control Units Operations/Service Manual 10600023 Rev. B 17
Connect the Camera Head
Remove the protective cap from the camera
cable connector. Connect the camera cable to
the CCU by aligning the red dot at the end of the
camera cable connector with the red dot on the
CCU camera cable receptacle and push in firmly
(Figure 6).
Note: If you are unfamiliar with cable
connectors, see the Equipment Setups section.
Also see the Equipment Setups section for
diagrams of equipment setup using an
automatic light source.
Connect the Video
Accessories
Install the video accessories using the diagrams
in the Equipment Setups section as a guideline.
Below are some tips regarding video setup:
• When connecting video accessories
(monitors, VCRs or printers) to the CCU,
always connect the cables using the video
camera outputs to the video inputs of the
accessory equipment.
• When linking pieces of equipment in a chain,
the last piece of equipment should be set in
the 75 Ω or the “ON” position. If there is not
a 75 Ωor “ON” switch, your equipment is
self-terminating and you do not need to
perform this step.
• When using monitors or printers having
RGB/SYNC settings, connect the RGB/SYNC
outputs on the camera directly to the
RGB/SYNC inputs of the accessory monitor
or printer. You should use a BNC style RGB
cable because the camera’s RGB/SYNC
outputs are standard BNC coaxial cable
connectors. Use the RGB input with the video
printer for best results.
• When connecting Super VHS recorders
(S-VHS), monitors or printers, connect the
4-pin mini-DIN Y/C (S-Video) connectors
directly to the Y/C (S-Video) input of the
accessory equipment.
Note: See the Equipment Setups section for
diagrams of multiple accessory setups and
configurations.
Preoperative Setup (continued)
Align the red dot at the end of the
camera head cable connector with
the red dot on the CCU camera cable
receptacle and push in firmly.
