RECESSED INSTALLATION
SUSPENDED CEILING
1. On top of the dome drive is an opening for an optional translator board. The opening has a cover that must be left in
place if a translator board is not required. A taller cover is supplied if a translator board is installed.
If you are going to install a translator board, follow the instructions that come with the translator board.
If you are not going to install a translator board, save the taller cover in case a translator board is ever installed.
2. Remove the ceiling tile from the ceiling.
3. Using the supplied template, cut holes in the ceiling tile for the dome drive and mounting hardware.
4. Remove the surface mount ring from the dome drive as follows. Refer to Figure 7.
a. Place fingers on the circular marks located on the sides of the surface mount ring.
b. Pinch the sides.
c. Lift and remove the surface mount ring from the dome drive. Do not discard the surface mount ring because it is
required to complete the installation.
5. Connect the wiring and attach the dome drive to the ceiling tile.
Using the supplied interface cable:
a. Plug the male RJ45-10 connector (also known as an RJ-50 connector) on the supplied interface cable (refer to
Figure 6) into the mating connector on top of the dome drive.
b. Turn the surface ring upside down, and place it on the inside of the ceiling tile. Refer to Figure 8.
c. Attach the dome drive to the ceiling tile and surface mount ring with the two #10 x 1.50-inch self-tapping
screws (supplied). Refer to Figure 8.
d. Replace the ceiling tile.
e. Remove an adjacent ceiling tile, and connect your wiring to the dome drive.
Refer to Figure 6, Table D, Table E, and Table F for wiring connections. Note that you can connect video using
either an unshielded twisted pair (UTP) of wires (refer to Table D) or coaxial cable (refer to Table E.) A BNC
connector for coaxial cable is attached to the dome drive.
If you are wiring more than one dome drive to the same transformer, connect one side of the transformer to pin
9 of the RJ45-10 connector on all modules. Connect the other side of the transformer to pin 10 of the RJ45-10
connector on all modules. Failure to connect all modules the same way will cause the cameras to be out of
phase with each other and may produce a vertical roll when switching between cameras.
WARNING:
Do not over-tighten the mounting hardware. Doing so can impede the pan movement of the
dome drive.
