CAUTION:
Make sure all peripheral equipment that will be connected to the fiber unit is turned OFF during
installation. Damage to equipment may result.
NOTE:
Belden number 9259 or equivalent RG59/U coaxial cable should be used between the video equipment and the fiber units.
Do not exceed the maximum distance recommended by the manufacturer of the video equipment.
NOTE:
Coaxial cable must be terminated with female BNC connectors to properly connect with the fiber links.
Connect the video equipment, such as a camera and monitor, to the input and output BNC jacks on the
S768DAV transmitter and receiver using terminated coaxial cable. See Figure 10.

ONNECTIONS
Audio input and output signals are connected to the 26-pin connector located on the back of the module,
or to the screw terminal connectors on the Interface board supplied with the unit. See Figure 10 and
Figure 11. Refer to Table 3 and Table 4 for wiring information.
NOTE:
Signal strength remains the same regardless of type of connection.
Audio connection options include:
!
Balanced transmitter input to balanced receiver output
!
Balanced transmitter input to unbalanced receiver output
!
Unbalanced transmitter input to unbalanced receiver output
!
Unbalanced transmitter input to balanced receiver output
1)
For a balanced connection, connect the external equipment to the (+) and (-) pins of the desired
channel.
2)
For an unbalanced connection, add a short jumper between the (-) pin and the ground pin.

Most cable manufacturers identify the individual fibers in the cable. Select appropriately terminated fiber
and mark both ends with a unique identification label (e.g. for cable no. 03, fiber no. 08) to ensure that the
fiber connected to the near end is the same as the one connected to the far end.
The proper optical connection will link the transmitter's TRANSMIT (OUT) port to the receiver's RECEIVE
(IN) port. See Figure 10.
1)
Wipe the inside of the port’s sleeve with a lint-free pipe cleaner moistened with reagent-grade
isopropyl alcohol. Blow dry with dry air.
2)
Clean the connector using a lint-free cloth dampened with reagent-grade isopropyl alcohol.
Thoroughly wipe the side and end of the ferrule. Blow the ferrule dry with dry air. Visually inspect
the ferrule for lint.
3)
Fasten the fiber optic cable to the port.
