The AVO-SVA2 balun allows the transmission
of a single S-Video signal and two analog audio
signals over unshielded twisted pair (UTP) cable,
such as Cat 5. Used in pairs, SVA2 baluns
eliminate costly and bulky S-Video cable,
allowing the connection of S-Video equipment
to any convenient modular outlet.
The SVA2 balun allows pre-existing twisted pair
cable to be used in such applications as
classroom video distribution, overhead projector
Installation
Caution: Do not attempt to open the balun housing. There are no user-serviceable parts
To install an AVO-SVA2 balun, perform the following steps:
1. Turn off power and disconnect the S-Video source and S-Video monitor.
2. Make certain the modular outlets and cross connects to which you will connect the
AVO-SVA2s are configured properly and labeled appropriately to identify the circuit.
Caution: Do not connect the AVO-SVA2 to a telecommunication outlet wired to
3. Verify the desired twisted pairs are not used with other LAN or telephone equipment.
4. Connect the balun to the S-Video port of the source equipment (i.e., DVD or VCR).
Connect the audio connectors to the audio source.
Caution: Do not mount the balun over equipment ventilation openings. Covering the
5. Connect a 4-pair Cat 5 cable from the RJ45 8-position modular jack of the AVOSVA2 to a structured cable, such as Cat 5.
6. Connect the second balun’s RCA inputs to the destination equipment.
7. Connect the 4-pair Cat 5 cable from the RJ45 8-position modular jack of another
AVO-SVA2 to the structured cable attached to the first balun.
8. Power on the S-Video equipment at both ends and adjust the monitor image and audio
levels to the desired settings.

and/or balun. Please ensure all wiring is “straight-through.”
openings may cause the equipment to overheat.
Troubleshooting
If your equipment malfunctions with AVO-SVA2 baluns in place, follow the troubleshooting procedures below:
How do I crimp an unshielded RJ45 connector onto Cat 5?
Crimping an RJ45 connector onto Cat 5 is a fairly straight forward task, assuming you have
the proper tools. Keep in mind that baluns require either the EIA/TIA 568A or 568B crimp
pattern, which are the industry standards for networking.
1. Perform diagnostics on your audio equipment by following the manufacturer’s
instructions.
2. Check all the connections and the structured cabling system. Verify the RJ45 crimp
pattern conforms to either EIA/TIA 568A or 568B standards.
3. Check the pin configuration of the structured cabling.
4. The maximum operational distances over which the AVO-SVA2 can be transmitted
is dependant on the equipment used and cable. Ensure that the maximum
recommended operational distances have not been exceeded.
5. Check that only twisted pair patch cords are being used.
6. Replace the AVO-SVA2 balun with another AVO-SVA2 that is known to be
working.
7. If you still cannot diagnose the problem, contact Intelix for support.
Frequently Asked Questions
How do I expose the individual pairs in Cat 5 cabling?
There is no single method when exposing the four
individual pairs in twisted pair cabling, such as Cat 5 and
Cat 6; however, it does help to have a cable stripping tool
designed to strip the cable jacket/insulation.
Begin by stripping back the cable’s outer jacket/insulation
about an inch (or more depending on whether multiple
baluns will be connected to the pairs of a single cable) so
that the internal wires are exposed. Be careful not to cut
the internal wires when stripping the insulation/jacket.
Eight twisted wires and a string should now be visible;
the string is unnecessary and may be removed. These
eight wires, which when combined form four pairs,
connect directly to the baluns. Typical protocol pairs
similar colors; the important thing is to verify the same
color-coded pairs are used on each end.
1. First, strip a portion of the insulation about 3/4" to expose the four twisted pairs.
2. Next, untwist the wires and fan them out so that they match either EIA/TIA 568A or
568B pattern.
3. Evenly trim the wires to about 1/2". Most RJ45 crimp tools feature a built-in wire
trimmer.
4. Insert the trimmed wires into the RJ45 connector so that each wire is in its individual
slot. Verify each wire is completely inserted.
5. Finally, insert the RJ45 connector into the crimp tool and squeeze firmly.
6. Repeat the above steps on the other end of the Cat 5 cable and verify pinout is iden-
tical on each end.
