VIDEO MONO AUDIO BALUNS
3. Installation
To install a pair of Video Mono Audio Baluns, take these steps:
CAUTION!
Do not attempt to open the housing. There are no user-serviceable parts
inside the Video Mono Audio Balun. Opening the unit will void your
warranty.
1. Make sure that the video devices at either end are not too far away from each
other (refer to the Maximum Distance specification in Chapter 1). If either
device is beyond the reach of the Balun at the other end, the signals the
device receives will be weak or nonexistent.
2. Follow the manufacturer’s instructions for (a) turning off power to the video
and audio equipment you will be attaching and (b) disconnecting that
equipment from AC power and from all other devices.
3. Make certain that the telecommunications outlets and cross-connects to
which you will connect the Baluns are configured properly and are labeled so
that the circuit can be identified.
4. Verify that the twisted-pair circuit you want to use is not already being used
for other LAN or telephone equipment.
CAUTION!
Do not connect the Video Mono Audio Balun to a telecommunication
outlet wired to unrelated equipment. Making such a connection may
damage the equipment and/or the Balun. Please make sure that all
wiring is straight-through-pinned.
Do not mount the Video Mono Audio Balun over equipment-
ventilation openings. Covering the openings may cause the equipment
to overheat.
5A. If your application is two-way (that is, one pair of audio/video signals going one
direction and one pair going the other direction): Run four RCA phono cables from
each balun to the attached device: one to the device’s VIDEO AUX IN port,
one to the device’s VIDEO AUX OUT port, one to the AUDIO IN port, and
the fourth to the AUDIO OUT port. (These cables must have RCA male
connectors on the Balun end.) Make sure that the VIDEO IN and AUDIO IN
ports on one end are connected to the VIDEO OUT and AUDIO OUT ports
on the other. Refer to Figure 3-1 on the next page.
