Connecting cables

A single RJ-45 cable connects to the back of the wall plate providing S-video, composite
video, power and RS-232 control. The front of the wall plate provides the break-out
connections for S-video, composite video, power and RS-232 control. The wall plate may be
attached to a standard single gang wall box or placed in an equipment rack in a surface
mount wall box A 50' Cat. 5 cable is included to connect the camera enclosure to the back
of the wall plate. It is best to use the included Cat. 5 cable. In situations where a third party
cable is necessary, the cable must be between 10' and 200' long. Using a longer cable may
cause the camera to lose power.

To connect to the wall plate

1. Plug the Cat. 5 cable into the RJ-45

connector on the rear of the camera
enclosure.

2. Feed the wire through the ceiling to where

the wall plate will be connected.

3. Connect the other end of the Cat. 5 cable

to the RJ-45 connector on the back of the
wall plate.

4. Install the wall plate into an electrical

box.

To connect to the display device and control system

1. Connect the 15 VDC power supply plug

into the 15 VDC jack.

2. Plug the power supply into a standard

wall outlet (100V-240V).

3. Using the 25' S-video cable, connect the

S-video jack to the display device at the
S-video connector.

Note: For display devices that do not have
an S-video connector, use a composite
cable (not included) to connect the
composite jack to the composite connector
on your display device.

4. Connect a serial cable to the control

system, if needed.

Attention: Use only the power supply
provided with the Ceiling DocCam II. Use
of any unauthorized power supply will void
warranty.

To mount the camera

1. Attach a string or plumb bob to

the ceiling tile with a thumb
tack.

2. Position the string directly over

ample table space or work
surface to allow easy document
and object positioning.

3. Using a sharp utility knife, score

a 3

" diameter hole into the

front of the tile centered on the
string.

4. Cut out the 3

" hole.

5. Place the tile support rail on the

back side of the tile and center over
the hole.

6. Rotate the camera enclosure module

so that the positioning indicator is
oriented toward the monitor or
display device. This position is
standard document camera
orientation.

Note: If the positioning indicator is
not oriented toward the monitor or
display device, your image will not
be oriented properly.

7. Fit the tile ring through the hole in

the tile, sandwiching the tile support between
the camera enclosure and the tile.
The camera tile ring will fit into the 3

opening from the rear of the tile.

8. Position the tile above the ceiling.

9. Attach the white trim ring to the camera

enclosure from the front of the tile and tighten
gently. This will pull the trim ring, camera
module and tile support rail together and
firmly hold the camera in position against the
ceiling tile.
